Top 10 original data warehousing features in Oracle Database 10g | killexams.com existent questions and Pass4sure dumps

Mark Rittman

Mark Rittman is a SearchOracle.com guest contributor. He is an OCP DBA and works as a consulting manager at Plus Consultancy in England, where he specializes in developing commerce intelligence and data warehousing applications using the Oracle Database, Application Server, Discoverer, Warehouse Builder and Oracle OLAP.

You can find more of Mark's labor at www.rittman.net/.

Plus Consultancy's tag Rittman shares what he believes are the top 10 original data warehousing features in Oracle Database 10g. utilize the following list to navigate to each feature.

  TABLE OF CONTENTS  1. The SQL Model Clause  2. The SQLAccess Adviser  3. Improvements to the Multidimensional OLAP Engine  4. The Tune MView Advisor and improvements to Query Rewrite  5. Data Pump, The replacement for import and export  6. Improvements to storage management  7. Faster full table scans  8. Automatic tuning and maintenance  9. Asynchronous Change Data Capture  10. Improvements to Oracle data mining

  1. The SQL Model clause[ return to Table of Contents ]

The original data warehousing feature in Oracle Database 10g that has probably received the most attention is the SQL Model clause. The SQL Model clause allows users to embed spreadsheet-like models in a SELECT statement, in a pass that was previously the domain of dedicated multidimensional OLAP servers such as Oracle Express and Oracle9i OLAP. The SQL Model clause brings an entirely original dimension to Oracle analytical queries and addresses a number of traditional shortcomings with the pass SQL normally works.

The SQL Model clause has been designed to address the sort of situation where, in the past, clients hold taken data out of relational databases and imported it into a model held in a spreadsheet such as Microsoft Excel. Often, these models involve a train of macros that aggregate data over a number of commerce dimensions, over varying time periods, and following a set of tangled commerce rules that would subsist difficult to express as balanced SQL. I've worked on many a client rendezvous where the limitations of SQL meant that a number of standalone exceed spreadsheets had to subsist used, and while these gave the client the analytical capabilities they required, the accustomed issues of scalability and reliability of replicated data, and requisite of overall control often became patent after a while.

The train of the SQL Model clause is to give balanced SQL statements the skill to create a multidimensional array from the results of a balanced SELECT statement, carry out any number of interdependent inter-row and inter-array calculations on this array, and then update the base tables with the results of the model. An example SQL statement using the MODEL clause would examine like;

SELECT SUBSTR(country,1,20) country, SUBSTR(prod,1,15) prod, year, sales FROM sales_view WHERE country IN ('Italy','Japan') MODEL return UPDATED ROWS PARTITION BY (country) DIMENSION BY (prod, year) MEASURES (sale sales) RULES ( sales['Bounce', 2002] = sales['Bounce', 2001] + sales['Bounce', 2000], sales['Y Box', 2002] = sales['Y Box', 2001], sales['2_Products', 2002] = sales['Bounce', 2002] + sales['Y Box', 2002]) ORDER BY country, prod, year;

More details on the SQL Model clause can subsist establish in "The original Oracle10g SQL Model Clause", the OracleWorld white paper "SQL Model clause of Oracle Database 10g", the OTN article "Announcing the original Model" by Jonathan Gennick and OTN's documentation.

  2. The SQLAccess Adviser[ return to Table of Contents ]

Part of the Oracle Database 10g Server Manageability feature, the SQLAccess Adviser recommends the best combination of indexes and materialized views for a given database workload. Available either at the command line (via the DBMS_ADVISOR package) or through the Advisor Central factor of the original Web-based Oracle Enterprise Manager, the SQLAccess Adviser is based on the index and summary advisors previously bundled with Oracle9i and provides a one-stop-shop for tuning and summarizing your warehouse data.

More details on the SQLAccess Adviser can subsist establish in this OracleWorld white paper, ""Turbocharge your database: utilize the Oracle Database 10g SQLAccess Advisor" by Lillian Hobbs, the OTN documentation and this Oracle-by-example tutorial.

  3. Improvements to the multidimensional OLAP engine[ return to Table of Contents ]

With Oracle9i, the previously standalone Express multidimensional engine is now incorporated into the Oracle database, and with Oracle Database 10g, benefits of integration with the traditional relational Oracle engine are starting to become apparent.

First up is improvements to the pass big analytic workspaces can subsist partitioned, introducing into the Oracle OLAP world some of the advanced partitioning options currently enjoyed by Oracle database users. Currently, analytic workspaces, stored as AW$ tables within an Oracle schema, can subsist partitioned across multiple rows in the AW$ table by specifying a maximum segment size, allowing you to split an individual analytic workspace into (say) 10 GB segments, one in each table row. This table could then subsist partitioned just fancy any other Oracle table, allowing you to do one row in one tablespace, another in another, and each of these tablespaces could of course subsist stored in datafiles on different physical disk units. Although this was of some benefit, splitting by segment size was the only pass of partitioning the data, and you couldn't specify what objects within the analytic workspace went in to each partition. Oracle10g OLAP will now comprise an enhancement where you can specify exactly which objects within the analytic workspace fade in to each partition, and you can further subdivide this by segment size if objects are particularly large.

In a similar fashion, variables within the analytic workspace can now subsist partitioned, either by orbit of dimension members, a list of dimension members, or by reference to a CONCAT dimension. The 10g multidimensional engine then stores each variable partition as a sever physical object, which can subsist directed to sever rows in the AW$ table (allowing you to partition these across different tablespaces and physical disk drives); the variable, however, appears as just one remonstrate to the application, simplifying the data model and allowing Oracle to outcome any the difficult labor in the background.

Another excellent original feature, and a existent improvement over what was available with Express, is support for multi-user read-write access to individual analytic workspaces. In the past, one drawback with Express was that only one user could attach to an Express database in read-write mode, leading Express developers to develop a total orbit of alternative solutions to allow ad-hoc write access to Express databases. In Oracle 10g OLAP, analytic workspaces can subsist attached in MULTI mode, whereafter applications then ACQUIRE individual variables in the analytic workspace for read-write access. Once an remonstrate has been acquired (and locked by the Oracle multidimensional engine), updates can then entrap region and the application can get whatever modifications are necessary. After any changes hold been made, the UPDATE command is issued against the variable, followed by a COMMIT, and then a RELEASE command is issued against the variable to get it available for other applications to write to. It'll subsist tantalizing to see how the multidimensional engine handles multi-write access; in the past with Express databases could balloon in size when one user had read-write access to a database, and others were accessing it in read mode, as Express had to clone the database for each user to ensure that they had a consistent view of the data. I wouldn't subsist surprised if individual variables were copied out of a 10g analytic workspace into a temporary workspace while updates happened, with updates being propagated back (as with the old-fashioned Express exceed Add-In) when the changes are finally COMMITted -- the key thing here is how database size is dealt with as the old-fashioned Express pass of doing it was less than optimal.

Aggregation has been improved with Oracle10g OLAP, with formulas now allowed as sources of data for the AGGREGATE command, eliminating the requisite to cipher and store data at the detail level. Aggregation, particularly dynamic aggregation, is another belt where Oracle9i and now 10g OLAP are a sever improvement over Express and it's well worth looking at this belt in more detail if this is an issue with an existing Express system.

More details on Oracle10g OLAP's original features can subsist establish in the OLAP Application Developer's Guide, the OLAP DML Reference and a white paper by Bud Endress, "OLAP Option to the Oracle10g Database."

  4. The Tune MView Advisor and improvements to Query Rewrite[ return to Table of Contents ]

Query Rewrite (the skill for Oracle to transparently redirect queries from detail flat to summary tables) is one of the best data warehousing features in Oracle8i and 9i, but it's sometimes a bit temperamental and you can often find that queries don't actually bag rewritten. Sometimes this is because you've broken one of the Query Rewrite restrictions, sometimes it's because your materialized view doesn't hold the rectify columns and aggregates. Oracle 10g has a number of improvements to Query Rewrite and the materialized view tuning process that should get this process a bit more productive. With Oracle Database 10g, query rewrite is now possible when your SELECT statement contains analytic functions, full outer joins and set operations such as UNION, MINUS and INTERSECT. In addition, you can now utilize a hint, /*+ REWRITE_OR_ERROR */, which will halt the execution of a SQL statement if query rewrite cannot occur.

SQL> SELECT /*+ REWRITE_OR_ERROR */ 2 s.prod_id, 3 sum(s.quantity_sold) 4 FROM sales s 5 GROUP BY s.prod_id; FROM sales s * oversight at line 4: ORA-30393: a query cloak in the statement did not rewrite

Oracle9i came with two packages, DBMS_MVIEW.EXPLAIN_MVIEW and DBMS_MVIEW.EXPLAIN_REWRITE that could subsist used to diagnose why a materialized view wasn't being used for query rewrite. However, although these packages told you why rewrite hadn't happened, they left it down to you to labor out how to alter your CREATE MATERIALIZED VIEW statement to ensure that rewrite happened correctly. Oracle Database 10g comes with a original advisor package, DBMS_ADVISOR.TUNE_MVIEW, that takes as its input a CREATE MATERIALIZED VIEW DML statement, and outputs a corrected version that supports query rewrite and features such as quickly refresh.

More details on Query Rewrite improvements and the Tune MView Adviser can subsist establish in the TUNE_MVIEW online documentation, the Query Rewrite online documents and this Oracle Database 10g Oracle-by-Example tutorial.

  5. Data Pump: The replacement for import and export[ return to Table of Contents ]

Data Pump is a replacement for the venerable IMP and EXP applications used for creating logical backups of Oracle tables, schemas or databases. Data Pump is a server application (as opposed to IMP and EXP, which were client applications), which in beta testing was twice as quickly as the old-fashioned EXP for exporting data, and 10 times as quickly as the old-fashioned IMP for importing data. Data Pump is callable either through the DBMS_DATAPUMP package, through the replacements for IMP and EXP, known as IMPDB and EXPDB, or through a wizard delivered as piece of Oracle Enterprise Manager 10g.

Data Pump (and the original IMPDB and EXPDB applications) offers a number of improvements over the old-fashioned IMPORT and EXPORT, including resumable/restartable jobs, automatic two-level parallelism, a network mode that uses DBLINKs/listener service names instead of pipes, fine-grained remonstrate selection (so you can select individual tables, view, packages, indexes and so on for import or export, not just tables or schemas as with IMPORT and EXPORT), and a fully callable API that allows Data Pump functionality to subsist embedded in third-party ETL packages.

More details on Data Pump can subsist establish in this OracleWorld white paper by George Claborn, "Data Pump in Oracle Database 10g: Foundation for ultra-high-speed data movement utilities,", OTN's online documentation and this Oracle-by-example tutorial.

  6. Improvements to storage management[ return to Table of Contents ]

Automatic Storage Management (ASM) is one of the 'cool original features' in Oracle10g that is meant to reduce the workload for Oracle DBAs. ASM completely automates the process of creating logical volumes, file systems and filenames, with the DBA only specifying the location of raw disks and ASM doing the rest. Disk I/O is managed by evenly distributing the data across blocks within a disk group, with ASM in addition handling disk mirroring and the creation of mirror groups and failure groups.

ASM deals with the problems caused by rapidly expanding data warehouses, where administators can no longer deal with the sheer number of disk units, nodes and logical groupings, and is a key feature of the Oracle 10g Grid Architecture, which aims to 'virtualize' computing power and present database features fancy processing and storage as utilities that effectively manage themselves.

More details on Automatic Storage Management can subsist establish in this OTN article by Lannes Morris-Murphy, this Oracle-by-example tutorial (which comes with a number of demonstration viewlets) and OTN's online documentation.

  7. Faster full table scans[ return to Table of Contents ]

Full table scans are common in data warehousing environments, and with this in mind, table scan performance has been improved in Oracle10g. Code optimization in Oracle Database 10g has decreased CPU consumption and this leads to faster table scan execution (when queries are CPU bound, rather than I/O bound), and gives the potential for greater query concurrency, offering up to 30-40% precipitate improvements when comparing CPU-bound queries.

  8. Automatic tuning and maintenance[ return to Table of Contents ]

Automatic maintenance and tuning has always been one of the key product differentiators for Microsoft SQL Server and with Oracle10g, features that meet and match those establish in competitor products are being introduced to the server technology stack.

Surveys flaunt that over 50% of a DBAs time is spend tuning and monitoring the database server, a job that while critical is often tangled and difficult to bag exactly right. With Oracle Database 10g, Oracle has introduced a number of components that together get it possible for the database server to monitor itself, get knowing changes to configuration, and alert DBAs when situations arise that requisite manual intervention.

The first component in this framework is the Automatic Workload Repository, which uses an enhanced version of Statspack to collect instance statistics every 30 minutes and stores these for a rolling seven day period. This enhanced version of Statspack now collects a broader orbit of statistics and has a number of optimizations to streamline the pass high-cost SQL statements are captured, ensuring that only SQL activity that has significantly affected performance since the final snapshot are collected. The usage information stored in the Automatic Workload Repository is then used as the basis for any the self-management functionality in Oracle Database 10g.

Next up is the Automatic Maintenance Tasks feature, which acts on the statistics gathered by the Automatic Workload Repository, and carries out tasks such as index rebuilding, refreshing statistics and so on, where such tasks don't require any manual intervention by the DBA. A original scheduling feature known as Unified Scheduler runs these tasks during a predefined maintenance window, set by default to subsist between 10:00 pm and 6:00 am the next day, although these times can subsist customized to reduce repercussion on other tasks (such as batch loads) that might subsist taking place.

The third component of the self-managing framework is Server Generated Alerts, a fashion where the database server sends notifications via e-mail to the DBA -- including a recommendation as to how best to deal with the situation. Alerts will normally subsist raised where the database itself cannot deal with the situation that has arisen, such as when there is insufficient space on a disk unit to extend a datafile.

Lastly, and perhaps the most exiting of any the self-managing component frameworks, is the Automatic Database Diagnostic Monitor. This component analyzes the data captured in the Automatic Workload Repository and uses an ersatz intelligence algorithm, similar to that establish in Oracle Expert, to resolve areas such as lock contention, CPU bottlenecks, I/O usage and contention, issues with checkpointing and so on, in much the identical pass that a DBA would currently outcome by analyzing statspack reports.

More details on the self-tuning and maintenance features in Oracle 10g can subsist establish in this OracleWorld white paper, "Oracle Database 10g: The self-managing database," by Sushil Kumar.

  9. Asynchronous Change Data Capture[ return to Table of Contents ]

Oracle Change Data Capture was introduced with Oracle9i, and provided the skill to track changes to tables and store them in a change table, for further consumption by an ETL process. Oracle9i Change Data Capture worked by creating triggers on the source tables, transferring data synchronously but creating a processing overhead and requiring access to the structure of the source tables. Because of the outcome that the triggers had on the underlying tables, many warehouse projects did without change data capture and used other methods to capture changes.

Oracle10g introduces Asynchronous Change Data Capture, which instead of using triggers uses the database log files to capture changes and apply them to collection tables. Asynchronous Change Data Capture therefore doesn't require changes to the table structure and doesn't repercussion on database performance.

More details on Asynchronous Change Data Capture can subsist establish in this OTN white paper, "On-time data warehousing with Oracle 10g -- Information at the precipitate of your business," which too details improvements to the transportable tablespaces feature in Oracle Database 10g (tablespaces no longer requisite to subsist sourced from the identical O/S platform).

  10. Improvements to Oracle data mining[ return to Table of Contents ]

Alongside the inclusion of the Oracle Express multidimensional OLAP engine, Oracle9i too embedded data mining functionality in the database together, and this data mining functionality has been enhanced with Oracle Database 10g. Oracle Database 10g adds support for two original classification routines, support Vector Machine (used for top-down rather than a bottom-up calculations, assuming the best possible lucky and then working backwards to what can subsist achieved) and Non-Negative Matrix Factorisation, together with support for Frequent Itemsets, used for such functions as market basket analysis and propensity analysis.

More details on what's original with Oracle10g Data Mining can subsist establish in the OTN online documentation.

Upgrading DBMS Versions and Releases | killexams.com existent questions and Pass4sure dumps

This chapter is from the engage 

Change is a fact of life, and each of the major DBMS products changes quite rapidly. A typical release cycle for DBMS software is 18 to 24 months for major releases, with constant bug fixes and maintenance updates delivered between major releases. Indeed, keeping DBMS software up-to-date can subsist a full-time job.

The DBA must develop an approach to upgrading DBMS software that conforms to the organization’s needs and minimizes commerce disruptions due to outages and database unavailability.

You may hold noticed that I utilize the terms version and release relatively interchangeably. That is fine for a broad discussion of DBMS upgrades, but a more precise definition is warranted. For a better discussion of the differences between a version and a release, gratify advert to the sidebar.

A DBMS version upgrade can subsist thought of as a special case of a original installation. any the procedures required of a original installation apply to an upgrade: You must objective for confiscate resources, reconsider any system parameters, and ensure that any supporting software is appropriately connected. However, another serious issue must subsist planned for: existing users and applications. An upgrade needs to subsist planned to antecedent as cramped disruption to the existing users as possible. Furthermore, any additional software that works with the DBMS (such as purchased applications, DBA tools, utilities, and so on) must subsist verified to subsist compatible with the original DBMS version. Therefore, upgrading can subsist a tricky and difficult task.

In a complex, heterogeneous, distributed database environment, a coherent upgrade strategy is essential. Truthfully, even organizations with only a sole DBMS should approach DBMS upgrades cautiously and objective accordingly. Failure to objective a DBMS upgrade can result in indecorous and inefficient adoption of original features, performance degradation of original and existing applications, and downtime.

Upgrading to a original DBMS release offers both rewards and risks. The following are some of the benefits of stirring to a original release:

  • Developers can avail themselves of original features and functionality delivered only in the original release. If evolution requires a original feature, or can simply capitalize from a original feature, program evolution time can subsist reduced or made more cost-effective.
  • For purchased applications, the application vendor may require a specific DBMS version or release for specific versions of its application to enable specific functionality within the application.
  • New DBMS releases usually deliver enhanced performance and availability features that can optimize existing applications. Sometimes a original DBMS release is required to scale applications to support additional users or larger amounts of data.
  • DBMS vendors often provide better support and respond to problems faster for a original release of their software. DBMS vendors are loath to allow unpleasant publicity about bugs in a original and heavily promoted version of their products.
  • Cost savings may accrue by upgrading to a original DBMS release. Some vendors charge additionally when a company uses multiple versions of a DBMS, such as the original version in a test environment and the old-fashioned in production. When both are migrated to the identical version, the cost tag for the DBMS sometimes can subsist reduced.
  • Production migration to a original DBMS release will align the test and production database environments, thereby providing a consistent environment for evolution and implementation. If a original release is running in the test environment for too long, database administration and application evolution tasks become more difficult because the test databases will operate differently from the production databases.
  • However, an efficacious DBMS upgrade strategy must balance the benefits against the risks of upgrading to arrive at the best timeline for migrating to a original DBMS version or release. The risks of upgrading to a original DBMS release comprise the following:

  • An upgrade to the DBMS usually involves some flat of disruption to commerce operations. At a minimum, databases will not subsist available while the DBMS is being upgraded. This can result in downtime and lost commerce opportunities if the DBMS upgrade occurs during balanced commerce hours (or if there is no planned downtime). Clustered database implementations may permit some database availability while individual database clusters are migrated to the original DBMS version.
  • Other disruptions can occur, such as having to transform database structures or discovering that previously supported features were removed from the original release (thereby causing application errors). Delays to application implementation timelines are another possibility.
  • The cost of an upgrade can subsist a significant barrier to DBMS release migration. First, the cost of the original version or release must subsist budgeted for (price increases for a original DBMS version can amount to as much as 10 to 25 percent). The upgrade cost must too factor in the costs of planning, installing, testing, and deploying not just the DBMS but too any applications that utilize databases. Finally, subsist sure to comprise the cost of any original resources (such as memory, storage, additional CPUs) required to utilize the original features delivered by the original DBMS version.6
  • DBMS vendors usually tout the performance gains that can subsist achieved with a original release. However, when SQL optimization techniques change, it is possible that a original DBMS release will generate SQL access paths that effect worse than before. DBAs must implement a rigorous testing process to ensure that original access paths are helping, not harming, application performance. When performance suffers, application code may requisite to subsist changed—a very costly and time-consuming endeavor. A rigorous test process should subsist able to entrap most of the access path changes in the test environment.
  • New DBMS releases may antecedent features and syntax that are being used in existing applications to subsist deprecated.7 When this occurs, the applications must subsist modified before migration to the original release can proceed.
  • To entrap edge of improvements implemented in a original DBMS release, the DBA may hold to apply some invasive changes. For example, if the original version increases the maximum size for a database object, the DBA may hold to drop and recreate that remonstrate to entrap edge of the original maximum. This will subsist the case when the DBMS adds internal control structures to facilitate such changes.
  • Supporting software products may requisite immediate support for a original DBMS release. Supporting software includes the operating system, transaction processors, message queues, purchased applications, DBA tools, evolution tools, and query and reporting software.
  • After weighing the benefits of upgrading against the risks of a original DBMS release, the DBA group must create an upgrade objective that works for the organization. Sometimes the decision will subsist to upgrade immediately upon availability, but often there is a lag between the general availability of a original release and its widespread adoption.

    When the risks of a original release outweigh the benefits, some organizations may choose to skip an interim release if doing so does not repercussion a future upgrade. For example, a noble number of Oracle customers migrated directly from Oracle7 to Oracle8i, skipping Oracle8. If the DBMS vendor does not allow users to bypass a version or release, it is noiseless possible to “skip” a release by waiting to implement that release until the next release is available. For example, account the following scenario:

  • ABC Corporation is using DB Version 8 from DBCorp.
  • DBCorp announces Version 9 of DB.
  • ABC Corporation analyzes the features and risks and determines not to upgrade immediately.
  • DBCorp later announces DB Version 10 and that no direct migration path will subsist provided from Version 8 to Version 10.
  • ABC Corporation decides that DB Version 10 provides many useful features and wants to upgrade its current Version 8 implementation of DB. However, it has no compelling reason to first implement and utilize Version 9.
  • To fulfill its requirements, ABC Corporation first upgrades Version 8 to Version 9 and then immediately upgrades Version 9 to Version 10.
  • Although a multiple-release upgrade takes more time, it allows customers to effectively control when and how they will migrate to original releases of a DBMS instead of being held hostage by the DBMS vendor. When attempting a multiple-release upgrade of this type, subsist sure to fully understand the features and functionality added by the DBMS vendor for each interim release. In the case of the hypothetical ABC Corporation, the DBAs would requisite to research and prepare for the original features of not just Version 10 but too Version 9.

    An confiscate DBMS upgrade strategy depends on many things. The following sections silhouette the issues that must subsist factored into an efficacious DBMS release upgrade strategy.

    Features and Complexity

    Perhaps the biggest factor in determining when and how to upgrade to a original DBMS release is the functionality supported by the original release. Tightly coupled to functionality is the inherent complexity involved in supporting and administering original features.

    It is more difficult to delay an upgrade if application developers are clamoring for original DBMS features. If DBMS functionality can minimize the cost and trouble of application development, the DBA group will feel pressure to migrate swiftly to the original release. An additional factor that will coerce rapid adoption of a original release is when DBMS problems are fixed in the original release (instead of through regular maintenance fixes).

    Regardless of a original release’s “bells and whistles,” inevitable administration and implementation details must subsist addressed before upgrading. The DBA group must ensure that standards are modified to comprise the original features, educate developers and users as to how original features labor and should subsist used, and prepare the infrastructure to support the original DBMS functionality.

    The types of changes required to support the original functionality must subsist factored into the upgrade strategy. When the DBMS vendor makes changes to internal structures, data page layouts, or address spaces, the risks of upgrading are greater. Additional testing is warranted in these situations to ensure that database utilities, DBA tools, and data extraction and movement tools noiseless labor with the revised internal structures.

    Complexity of the DBMS Environment

    The more tangled your database environment is, the more difficult it will subsist to upgrade to a original DBMS release. The first complexity issue is the size of the environment. The greater the number of database servers, instances, applications, and users, the greater the complexity. Additional concerns comprise the types of applications being supported. A DBMS upgrade is easier to implement if only simple, batch-oriented applications are involved. As the complexity and availability requirements of the applications increase, the hardship of upgrading too increases.

    Location of the database servers too affects the release upgrade strategy. Effectively planning and deploying a DBMS upgrade across multiple database servers at various locations supporting different lines of commerce is difficult. It is likely that an upgrade strategy will involve periods of supporting multiple versions of the DBMS at different locations and for different applications. Supporting different versions in production should subsist avoided, but that is not always possible.

    Finally, the complexity of the applications that access your databases must subsist considered. The more tangled your applications are, the more difficult it will subsist to ensure their continuing uninterrupted functionality when the DBMS is modified. Complexity issues comprise the following:

  • Usage of stored procedures and user-defined functions.
  • Complexity of the SQL—the more tables involved in the SQL and the more tangled the SQL features, the more difficult it becomes to ensure that access path changes outcome not repercussion performance.
  • Client/server processing—network usage and usage of multiple tiers complicates testing the original DBMS release.
  • Applications that are designed, coded, and generated by a framework or an IDE (for example, Hibernate) may hold additional components that requisite to subsist tested with a original DBMS release.
  • Integration with other infrastructure software such as message queues and transaction processors can complicate migration because original versions of these products may subsist required to support the original DBMS release.
  • The language used by the programs might too repercussion DBMS release migration due to different support for compiler versions, changes to APIs (application programming interfaces), or original ways of embedding SQL into application programs.
  • Reputation of the DBMS Vendor

    DBMS vendors hold different reputations for technical support, fixing bugs, and responding to problems, which is why customer references are so critical when choosing a database.

    The better the reputation of the vendor, the greater the likelihood of organizations rapidly adopting a original release. If the DBMS vendor is noble at responding to problems and supporting its customers as they migrate to original releases, those customers will more actively engage in migration activities.

    Support Policies of the DBMS

    As original releases are introduced, DBMS vendors will retire older releases and no longer support them. The length of time that the DBMS vendor will support an old-fashioned release must subsist factored into the DBMS release migration strategy. You should never dash a DBMS release in production that is no longer supported by the vendor. If problems occur, the DBMS vendor will not subsist able to resolve them for you.

    Sometimes a DBMS vendor will provide support for a retired release on a special basis and at an increased maintenance charge. If you absolutely must continue using a retired DBMS release (for commerce or application issues), subsist sure to investigate the DBMS vendor’s policies regarding support for retired releases of its software.

    Organization Style

    Every organization displays characteristics that divulge its style when it comes to adopting original products and technologies. Industry analysts at Gartner, Inc., hold ranked organizations into three sever groups labeled types A, B, and C. A type-A enterprise is technology driven and, as such, is more likely to risk using original and unproven technologies to try to gain a competitive advantage. A type-B organization is less willing to entrap risks but will adopt original technologies once others hold shaken out the bugs. Finally, a type-C enterprise, very conscious of cost and averse to risk, will lag behind the majority when it comes to migrating to original technology.

    Only type-A organizations should objective on stirring aggressively to original DBMS releases immediately upon availability and only if the original features of the release will deliver advantages to the company. Type-C enterprises should adopt a very conservative strategy to ensure that the DBMS release is stable and well tested by type-A and type-B companies first. Type-B organizations will topple somewhere between types A and C: Almost never upgrading immediately, the type-B company will adopt the original release after the earliest users hold shaken out the biggest problems, but well before type-C enterprises.

    DBA Staff Skill Set

    Upgrading the DBMS is easier if your DBA staff is highly skilled and/or experienced. The risk of an upgrade increases as the skills of the DBA staff decrease. If your DBAs are not highly skilled, or hold never migrated a DBMS to a original release, account augmenting your DBA staff with consultants for the upgrade. Deploying an integrated team of internal DBAs and consultants will ensure that your upgrade goes as smoothly as possible. Furthermore, the DBA staff will subsist better prepared to ply the future upgrades alone.

    If consultants will subsist required, subsist sure to comprise their contracting cost in the DBMS release upgrade budget. The budget should allow you to retain the consultants until any production database environments are stable.

    Platform Support

    When a DBMS vendor unleashes a original release of its product, not any platforms and operating systems are immediately supported. The DBMS vendor usually first supports the platforms and operating systems for which it has the most licensed customers. The order in which platforms are supported for a original release is likely to disagree for each DBMS vendor. For example, Linux for System z is more strategic to IBM than to Oracle, so a original DB2 release will most likely support Linux for System z very quickly, whereas this may not subsist noble of Oracle. The issue is even thornier for UNIX platforms because of the sheer number of UNIX variants in the marketplace. The most common variants are Oracle’s Solaris, IBM’s AIX, Hewlett-Packard’s HP-UX, and Linux, the open-source version of UNIX (the Red Hat and Suse distributions are supported more frequently and rapidly than others). Most DBMS vendors will support these UNIX platforms quickly upon general availability. Other less common varieties of UNIX will entrap longer for the DBMS vendors to support.

    When planning your DBMS upgrade, subsist sure to account the DBMS platforms you utilize and try to gauge the priority of your platform to your vendor. subsist sure to build some lag time into your release migration strategy to accommodate the vendor’s delivery schedule for your specific platforms.

    Supporting Software

    Carefully account the repercussion of a DBMS upgrade on any supporting software. Supporting software includes purchased applications, DBA tools, reporting and analysis tools, and query tools. Each software vendor will hold a different time frame for supporting and exploiting a original DBMS release. Review the sidebar to understand the divergence between support and exploitation of a original DBMS release.

    Some third-party utensil vendors ensue guidelines for supporting and exploiting original DBMS releases. Whenever possible, inquire your vendors to status their policies for DBMS upgrade support. Your vendors will probably not confide to any difficult date or date orbit to support original versions and releases—some DBMS versions are larger and more complicated and therefore entrap longer to fully exploit.

    Fallback Planning

    Each original DBMS version or release should advance with a manual that outlines the original features of the release and describes the fallback procedures to return to a prior release of the DBMS. subsist sure to review the fallback procedures provided by the DBMS vendor in its release guide. You may requisite to return to a previous DBMS release if the upgrade contains a bug, performance problems ensue, or other problems arise during or immediately after migration. support in intelligence that fallback is not always an option for every original DBMS release.

    If fallback is possible, ensue the DBMS vendor’s recommended procedures to enable it. You may requisite to delay the implementation of inevitable original features for fallback to remain an option. Understand fully the limitations imposed by the DBMS vendor on fallback, and exploit original features only when fallback is no longer an option for your organization.

    Migration Verification

    The DBA should implement procedures—similar to those for a original installation—to verify that the DBMS release upgrade is satisfactory. effect the identical steps as with a brand-new DBMS install, but too test a representative sampling of your in-house applications to verify that the DBMS upgrade is working correctly and performing satisfactorily.

    The DBMS Upgrade Strategy

    In general, design your DBMS release upgrade policy according to the guidelines discussed in the preceding sections. Each specific DBMS upgrade will subsist unique, but the strategies we’ve discussed will alleviate you to achieve success more readily. A well-thought-out DBMS upgrade strategy will prepare you to support original DBMS releases with minimum repercussion on your organization and in a style best suited to your company.
