probably the most helpful construction techniques are tailor-made to the enterprise and product IT groups are working with. probably the most effective groups enhance standardized techniques that advocate nick back mistakes and velocity up the software birth lifecycle while expanding efficiency for their selected product.
DevOps spans americans, system, and know-how, and may breathe integrated into every IT group. mixed with most trustworthy practices for each and every team’s technical landscape, it might probably create more effective tactics that deliver high-quality application to market in less time.
That’s very accurate for IT teams engaged on Oracle apps corresponding to E-business Suite. Combining DevOps practices with inescapable edifice tips for E-business Suite will get complete groups greater valuable and produce more desirable consequences for conclusion clients.
At Flexagon, we’ve been assisting IT groups integrate DevOps practices and rig into their existing strategies for years – and maintain profound potential in Oracle know-how, including E-enterprise Suite. We’ve combined their journey with E-enterprise Suite with widely wide-spread DevOps and development most excellent practices to create a list of 10 edifice assistance for Oracle EBS.
These advice will aid developers standardize their tactics, store time, and nick back errors during construction, testing, and deployment to production. They might too even get a contribution to your efforts to shorten the utility surge lifecycle and should acclaim continuous methodologies like continual integration and continuous birth.most fulfilling Practices for E-company Suite development1. Standardize Naming Conventions
Don’t waste time naming database objects in response to mediocre conventions, then the exercise of ad hoc naming for file gadget objects. as a substitute, Come up with naming conventions that can breathe easily replicated in scripts, executables, reports, kinds and extra. via taking this approach from the beginning, any out-of-context coding, as an instance in a JIRA ticket, can too breathe readily understood.2. song AOL changes to your SCM
building groups most commonly implement AOL adjustments in a shared EBS development atmosphere. for the intuition that EBS does not preserve song of revisions of alterations, it is premiere exercise to extract every AOL change to an .LDT and checklist the revision as a relegate into your source control equipment.
that you would breathe able to exercise DevOps tooling to automate the migration of the AOL adjustments the exercise of the FNDLOAD program. as with every file, you could maintain visibility into which revisions of your AOLs the residence deployed, when, where, and by using whom.3. Simplify Server administration and in the reduction of complications with Automation
Oracle E-enterprise Suite consists of a variety of servers, features, and workflows. each and every of those components requires diverse handling to cease, start, restart, permit, or disable. Managing these diverse server components isn't a straightforward project. Automating server management is essential for creation environments for perquisite here purposes:
alas, it’s ordinary for IT teams emigrate packages, then discover that they aren’t working with the newest version of the code. no longer handiest is that irritating, however too wastes time and extends your software surge lifecycle.
instead of struggling to establish which edition of the code you’re working with, get reviewing kit versions less demanding with the aid of including a version code perquisite after the header revision comments in your PL/SQL package. This may too breathe completed manually via the team or by using DevOps equipment and continuous strategies to get inescapable here is accomplished every time code is migrated.5. structure Your Code
All coding – no longer handiest packages being readied for migrations – may silent keep ordinary protocols. The direct perquisite here is to get the software’s code as simple and readable as possible. exercise the case office or indent code invariably to get code fragments convenient and predictable to read.
whatever code structure you employ, preserve it constant outright over your company. everybody may silent breathe in a position to with no calamity view and understand code the usage of the identical system.6. breathe watchful of When to exercise Patch vs. race edition
Oracle E-business 12.2 and above comes with versions (Run and Patch). which you could set up your customizations without delay to race edition or apply to Patch version (online Patching) with the aid of following ADOP patching phases. on-line Patching cycle consists of the following principal phases:
online patching reduces downtime and is too known as 0 downtime deployment.
you could set up adjustments without delay into the race edition. This alternative should breathe used when alterations are diminutive or when the unusual on-line patching alternate options aren't adopted.7. Create Reusable Frameworks
Your IT team doesn’t necessity to disburse time getting to know unusual construction frameworks and specifications until there’s a particular need. So, as you create frameworks to develop your latest Oracle functions, breathe positive they can too breathe replicated in future implementations.
for example, you could enhance a common set of 20 inventory categories that ensue a group of naming conventions that can breathe used across tasks. exercise these frameworks throughout teams and with your entire Oracle EBS development tools to create in-apartment necessities that maintain time.eight. reduce manual, Repeatable projects with Idempotent Database Scripts
EBS implementations are composed of colossal volumes of database objects and PL/SQL programs. infatuation several EBS object, these definitions necessity to breathe synchronized across many environments in your topology. frequently, these objects are migrated across environments with the aid of the DBA by executing DDL/SQL scripts offered by using the construction team.
one of the greatest challenges in automating the system is managing updates to existing Oracle database objects. here's relatively fundamental for objects which maintain CREATE OR substitute objects, however that isn't the case for a lot of of the article varieties (e.g. tables, indexes, sequences, and many others.). as an example, you can not execute a create desk statement if the desk already exists. here is most frequently managed by passage of writing scripts which are elegant on the situation of the expostulate in the goal atmosphere. When it involves automating the manner, this becomes a challenge.
One technique is to create outright DDL/SQL scripts to breathe idempotent, yielding the identical outcomes even when applied a number of times. in case you keep this observe, that you can maintain a sole script it really is used to ensue alterations throughout outright environments, tune the revision of the script throughout environments, and foster healthier relationships between developers and DBAs.
There are distinctive recommendations used, which vary by expostulate classification. In most cases, youngsters, the scripts necessity to investigate the present situation and undertake its conduct. For staging tables or stateless objects, effectively shedding and re-developing the expostulate is the most advantageous formula (taking supervision not to fail if the item does not exist). For stateful objects, akin to permanent tables and sequences, you must deal with insert/replace circumstances, outright whereas maintaining any state.9. steer pellucid of challenging Coding
challenging code or configure? The option appears glaring, however it bears repeating: always configure to preclude problems and further labor down the highway.
In times in case you believe inclined to allocate values to your code – either strings or numeric – esteem where else you can earn this records. If it’s not accessible elsewhere, it's most effective to seize the time to strengthen custom profile options, descriptive flex fields (DFF) or key flex fields to extra with no calamity itemize categories.10. Automate and neighborhood initiatives together
Most companies maintain a brace of environments for numerous purposes infatuation building, device checking out, performance trying out, creation, etc. For successful delivery of features to construction, it's essential that development groups adopt automation practices.
Automation can too breathe employed to carry out a variety of mundane tasks infatuation configuration and code deployment, excellent testing, and more. Automation should silent advocate remain away from errors and drive consistency, which means a discount in downtime and outages. In instances the residence projects deserve to breathe performed outright over late nighttime or weekend hours, automation and scheduling can additionally encourage ameliorate work-lifestyles steadiness.
As corporations undertake automation, it is a fine design to provide tools for visibility into computerized changes to diagnose problems or for audit tracking for a variety of compliance methods. tools that get it handy to group changes together for merchandising can too also encourage you control your EBS application start lifecycle that spans anyplace from just a few days to weeks or months.Use specifications and Automation to enhance Oracle E-company Suite App building
Oracle products are extremely really good, and IT groups engaged on them typically boost their personal in-condominium processes in accordance with instructions from Oracle and adventure with E-company Suite. Framing that into requirements and automating processes to nick back guide, repeatable projects and reduce down on errors can vastly ameliorate app construction.
To complement your in-apartment tactics and most trustworthy practices, which you can additionally believe adding DevOps rig with software unencumber automation and other functionality to your IT toolset. These rig will additional alleviate the burden of steer labor in your crew, helping streamline processes and mainstreaming the optimal practices which are already on your tactics.
Oracle today introduced a slew of recent cloud capabilities at its OpenWorld adventure in San Francisco nowadays, including the Oracle Elastic Compute Cloud. The launch comes 9 years after Amazon humbly launched EC2, which has whirl into a criterion in cloud infrastructure.
Oracle executives maintain previously talked about offering infrastructure as a carrier — whatever thing that might vie the likes of Amazon web services, which has grown from the EC2 side trade into a company unit that now produces $2 billion in profits in a sole quarter. but now there is an actual IaaS provider with genuine expenses. perquisite here’s a product description from nowadays’s press liberate:

In the billing migration blog post published a few weeks ago, they explained the overall approach employed in migrating their billing system to the cloud:
In this post, the database migration portion will breathe covered in detail. They hope that their experiences will encourage you as you undertake your own migrations.
Have you ever wondered about the elements that necessity to Come together and align to earn a complicated database migration right? You might ask, “What makes it complicated?”
Think of any challenge in database migration and pretty much outright of them were there in this migration:
Billing, as most of you would agree, is the censorious service for any company. The database is the most essential constituent in any migration and getting it perquisite determines the success or failure of the whole project. The Netflix CDE (Cloud Database Engineering) team was tasked with migrating this censorious subsystem database. The following sections report some of key areas they focused on in order to ensure a successful migration.Choice of the database
Billing applications maintain transactions that necessity ACID compliance to process the payment for charged transactions. RDBMS seemed the perquisite selection for the datastore.
Oracle: As source database was in Oracle, migrating to Oracle in Cloud would avoid cross database migration, simplifying the coding endeavor and configuration setup. Their savor with Oracle in production gave more self-confidence with respect to its performance and scalability. However, considering the licensing costs and the technical debt required to migrate legacy data “as is”, prompted us to explore other options.
AWS RDS MySQL: Ideally they would maintain gone with MySQL RDS as their backend, considering Amazon does a noteworthy job in managing and upgrading relational database as a service, providing multi-AZ advocate for tall availability. However, the main drawback to RDS was the storage confine of 6TB. Their requirement at the time, was closer to 10TB.
AWS Aurora: AWS Aurora would maintain met the storage needs, but it was in beta at that time.
PostgreSQL: PostgreSQL is a powerful open source, object-relational database system, but they did not maintain much in house expertise using PostgreSQL. In the DC, their primary backend databases were Oracle and MySQL. Moreover, choosing PostgreSQL would maintain eliminated the option of a seamless migration to Aurora in future, as Aurora is based on the MySQL engine.
EC2 MySQL: EC2 MySQL was ultimately the selection for the billing exercise case, since there were no licensing cost and it too provided a path to future Aurora migration. This involved setting up MySQL using the InnoDB engine on i2.8xlarge instances.Production Database Architecture
High availability and scalability were the main drivers in designing the architecture to encourage the billing application withstand infrastructure failures, zone and region outages, and to carry out so with minimal downtime.
Using an DRBD copy in another zone for the primary master DB, helped withstand zone outages, infrastructure failures infatuation execrable nodes, and EBS volume failures. “Synchronous replication protocol” was used to enable the write operations on the primary node to breathe considered completed, only after both the local and remote writes maintain been confirmed. As a result, the loss of a sole node is guaranteed to maintain no data loss. This would repercussion the write latency, but that was well within the SLAs.
Read replica setup in local, as well as cross region, not only met tall availability requirements, but too helped with scalability. The read traffic from ETL jobs was diverted to the read replica, sparing the primary database from massive ETL batch processing.
In case of the primary MySQL database failure, a failover is performed to the DRBD secondary node that was being replicated in synchronous mode. Once secondary node takes over the primary role, the route53 DNS entry for database host is changed to point to the unusual primary. The billing application being batch in nature is designed to maneuver such downtime scenarios. The client connection carry out not fallback but establish unusual connections that would point to the unusual primary after the Cname propagation is complete.Choice of Migration Tool
We spent considerable time and endeavor in choosing the perquisite tool for the migration. Primary success criteria for the POC was the ability to restart bulk loads, bi-directional replication, and data integrity. They focused on the following criteria while evaluating a tool for the migration.
GoldenGate stood out in terms of features it offered which aligned very well with their exercise case. It offered the ability to restart bulk loads in case of failures (a few tables were hundreds of GB in size), and its bi-directional replication feature provided easy rollback from MySQL to Oracle.
The main drawback with GoldenGate was the learning curve in understanding how the tool works. In addition, its manual configuration setup is prostrate to human error, which added a layer of difficulty. If there is no primary key or unique key on the source table, GoldenGate uses outright columns as the supplemental logging key pair for both extracts and replicats. They institute issues infatuation duplicate data at the target in incremental loads for such tables and decided to execute a replete load during the cutover for those specific tables with no pre-defined primary or unique key. The advantages and features offered by GoldenGate far exceeded any challenges and was the tool of choice.Schema Conversion and Validation
Since source and target databases were different, with data sort and data length differences, validation became a crucial step in getting the data migrated while keeping the data integrity intact.
Data sort mismatch took sometime to fix the issues stemming from it. One example — many numeric values in Oracle were defined as the Number datatype for legacy reasons. There is no equivalent sort in MySQL. The Number datatype in Oracle stores fixed and floating-point numbers which was tricky. Some source tables had columns where Number meant an integer, in other cases it was used for decimal values, while some had really long values up to 38 digits. In contrast, MySQL has specific datatypes infatuation Int, bigInt, decimal, double etc and a bigInt cannot proceed beyond 18 digits. One should ensure that amend mapping is done to reflect the accurate values in MySQL.
Partitioned tables needed special handling, since unlike Oracle, MySQL expects the partition key to breathe the Part of the primary key and unique key. Target schema had to breathe redefined with proper partitioning keys to ensure no negative repercussion on application logic and queries.
Default value handling too differs between MySQL and Oracle. For the columns with a NOT NULL value, MySQL determined the implicit default value for the column. Strict mode had to breathe enabled in MySQL to trap such data conversion issues, as such transactions would fail and pomp up in the GoldenGate error logs.
Tools for schema conversion: They researched a variety of tools to assist in schema conversion as well as validation, but the default schema conversion provided by these tools did not labor due to their legacy schema design. Even GoldenGate does not transmogrify Oracle schema to the equivalent MySQL version, but instead depends on the application owners to define the schema first. Since one of their goals with this migration was to optimize schema, the database and application teams worked together to review the data types, and did multiple iterations to capture any mismatch. GoldenGate will truncate the value to felicitous the MySQL datatype in case of a mis-match. They relied heavily on data comparison tools and the GoldenGate error logs to encourage detect mismatches in data sort mapping between source and target, in order to mitigate this issue.Data Integrity
Once the replete load completed and incrementals caught up, another daunting task was to get positive the target copy correctly maintained the data integrity. As the data types between Oracle and MySQL were different, it was not possible to maintain a generic wrapper script to compare hash values for the rowkeys to ensure accuracy. There are a few 3rd party tools which carry out the data comparisons across databases comparing the actual values, but the total dataset is 10 TB which was not easy to compare. Instead, they used these tools to match a sample data set which helped in identifying a few discrepancies related to wrong schema mapping.
Test refreshes: One of the ways to ensure data integrity was to carry out the application testing on a copy of the production database. This was accomplished by scheduling database refreshes from the MySQL production database to test. Considering production was being backed by EBS for storage, a test environment was easily created by taking the EBS snapshots off the slave, and doing a point in time recovery into test. This process was repeated several times to ensure data quality.
Sqoop jobs: ETL jobs and reporting were used to encourage with data reconciliation process. Sqoop jobs pulled data out of Oracle for reporting purposes. Those jobs were too configured to race against MySQL. With continuous replication between source and target, reports were race against specific time window on the ETLs. This helped in taking out the variation due to incremental loads.
Row counts was another technique used to compare the source/target and match them. This was achieved by pausing the incremental loads on the target and matching the counts on Oracle and MySQL. Results from row counts were too compared after replete GoldenGate load of the tables.Performance Tuning
Infrastructure: Billing application persisted data in the DC on two Oracle databases residing on very powerful machines, using IBM power 7, 32 dual core 64 bit multiprocessors, 750GB RAM, TB’s storage allocated via SVC MCS cluster which is 8G4 cluster with 4GB/sec interface running with RAID 10 configurations.
One major concern with the migration was performance, as the target database was consolidated on one i2.8xlarge server, using 32 vCPU and 244 GB RAM. The application team did a lot of tuning at the application layer to optimize the queries. With the encourage of Vector the performance team was able to find bottlenecks and liquidate them by tuning specific system and kernel parameters. espy Appendix for more details.
High performance with respect to reads and writes was achieved by using RAID0 with EBS provisioned IOPS volumes. To earn more throughput per volume, 5 volumes of 4TB each were used, instead of 1 great volume. This was to facilitate faster snapshots and restores.
Database: One major concern using MySQL was the scale of their data and MySQL throughput during batch processing of data by billing applications. Percona provided consulting support, and the MySQL database was tuned to accomplish well during and after the migration. The main trick is to maintain two cnf files, one while migrating the data and tweaking parameters infatuation innodb_log_file_size to encourage with bulk inserts, and the second cnf file for the true time production application load by tweaking parameters infatuation innodb_buffer_pool_instances to encourage with the transaction true time load. espy Appendix for more details.
Data load: During POC, they tested the initial table load with indexes in on/off combination and decided to proceed with enabling outright indexes before the load. The reasoning behind this was that index creation in MySQL is sole threaded (most tables had multiple indexes), and so they instead utilized Golden Gate’s parallel load feature to populate the table with indexes in reasonable time. alien key constraints were enabled during the final cutover.
Another trick they erudite was to match the total number of processes executing replete and incremental load, to the number of cores on the instance. If the processes exceeded the number of cores, the performance of those data loads slowed down drastically as the instance would disburse a lot of time in context switches. It took around 2 weeks to populate 10 TB in target MySQL database with the replete loads and maintain incremental loads trap up.Conclusion
Though the database piece is one of the most challenging aspects of any migration, what really makes a disagreement between success and failure is ensuring you are investing in the perquisite approach up front, and partnering closely with the application team throughout the process. Looking back on the whole migration, it was truly a commendable endeavor by different teams across the organization, who came together to define the whole migration and get the migration a noteworthy success! Along with the individual and cross team coordination, it’s too the noteworthy culture of freedom and responsibility which makes these challenging migrations possible without impacting business.Appendix Database Tunables for Bulk Insert Database Tunables for tall Transaction throughput Storage

Edward Whalen, an Oracle ACE and the Chief Technologist at Performance Tuning Corporation (www.perftuning.com), was recently featured in an Oracle Enterprise Manager SIG webinar about Oracle Enterprise Manager 12c. Here, he shares his thoughts about the significance of the features provided in the latest release of Enterprise Manager and why they are Important to Oracle users.
Why are you interested in Enterprise Manager 12c?EW: Oracle Enterprise Manager Cloud Control is the latest and greatest Enterprise Manager product from Oracle. In terms of lifecycle management, in terms of managing the database, and in terms of just managing the whole enterprise, it has got some noteworthy features.
In the webcast, I focused on the performance management tools within the Oracle Database, which are ASH Analytics and SQL Monitoring. The intuition I was asked to participate is that Oracle Press actually just published a book that I wrote on this topic with my colleagues, Michael New and Matthew Burke, titled, “Oracle Enterprise Manager Cloud Control 12c profound Dive.”
Do you exercise Enterprise Manager?
EW: I exercise this technology outright the time. I am a database consultant and I mainly focus on performance problems as well as implementations and data migrations, so I exercise technologies such as Oracle GoldenGate, Data Guard, and Oracle RAC. Oracle Enterprise Manager Cloud Control 12c really provides a lot of capabilities for managing these features of Oracle and gives you the ability to not only manage but monitor and set up alerting. I implement, configure and manage Oracle Enterprise Manager 12c for a number of customers. I supervision for Oracle Enterprise Manager 12c. I am a huge fan of the product.
Do your customers find it helpful?
EW: It is extremely useful. The database administrator’s main task in life is to maintain the database up and running. So being able to set up proactive alerts and proactive monitoring and pinpoint when something is happening before the user community is calling to complain about it, is really essential to DBAs in order to provide a really noteworthy level of service for their customers and discontinue users.
How did Oracle Enterprise Manager 12c evolve as a product?
EW: The 12c version of Oracle Enterprise Manager actually came out a replete year before the 12c version of the database. The version 12c of Enterprise Manager doesn’t require the 12c version of the database and, in fact, 12c can manage and monitor not only 12c databases but 11g databases, 10g, 9i, and so forth. Prior to Oracle Enterprise Manager Cloud Control, the product was called Oracle Grid Control. Version 10 and version 11 of Oracle Grid Control maintain been out there for awhile and then with version 12c, Oracle named it Cloud Control.
The unusual feature for performance monitoring and performance tuning is a feature only available in Oracle Enterprise Manager called ASH Analytics. ASH stands for lively Session History so ASH Analytics is what I covered in the webinar – showing how it allows you to dig into what is actually happening in your system on a per-session level even to the point of allowing you to sequester which session and which SQL statement is using the most I/O, or has the greatest CPU utilization, or which ones are holding the most locks. I am able to dig into those details with the ASH Analytics tool and that is a unusual feature that was not available in the earlier versions of Grid Control.
How long maintain you been a member of the IOUG?
EW: More than 15 years.
What has your savor been?
EW: I supervision for the IOUG. I especially infatuation the IOUG presentations at COLLABORATE because they provide more of the actual down and filthy database administration – really technical information. If you want to learn something about Oracle products and learn about how the DBAs labor and what kind of things they race into, you mind to find more about that at COLLABORATE.
What is it that you will breathe looking for more information on at Oracle OpenWorld this year?
EW: I am mainly looking forward to getting more information about the unusual features in Oracle 12c Database. I too labor quite a lot with Oracle GoldenGate and I know they are making a lot of improvements there, so I am planning on attending a few of those sessions as well.

The most effective development processes are tailored to the company and product IT teams are working with. The most effective teams develop standardized processes that encourage reduce errors and hasten up the software delivery lifecycle while increasing efficiency for their specific product.
DevOps spans people, process, and technology, and can breathe integrated into every IT team. Combined with best practices for each team’s technical landscape, it can create more efficient processes that deliver high-quality software to market in less time.
That’s especially accurate for IT teams working on Oracle apps such as E-Business Suite. Combining DevOps practices with specific development tips for E-Business Suite will get entire teams more effective and produce greater results for discontinue users.
At Flexagon, we’ve been helping IT teams integrate DevOps practices and tools into their current processes for years – and maintain profound expertise in Oracle technology, including E-Business Suite. We’ve combined their savor with E-Business Suite with common DevOps and development best practices to create a list of 10 development tips for Oracle EBS.
These tips will encourage developers standardize their processes, redeem time, and reduce errors throughout development, testing, and deployment to production. They may even contribute to your efforts to shorten the software delivery lifecycle and will compliment continuous methodologies like continuous integration and continuous delivery.Best Practices for E-Business Suite Development 1. Standardize Naming Conventions
Don’t waste time naming database objects based on criterion conventions, then using ad hoc naming for file system objects. Instead, Come up with naming conventions that can breathe easily replicated in scripts, executables, reports, forms and more. By taking this approach from the beginning, any out-of-context coding, for instance in a JIRA ticket, can breathe easily understood.2. Track AOL Changes in Your SCM
Development teams most often implement AOL changes in a shared EBS development environment. Since EBS does not maintain track of revisions of changes, it is best exercise to extract each AOL change to an .LDT and record the revision as a relegate into your source control system.
You can exercise DevOps tooling to automate the migration of the AOL changes using the FNDLOAD program. As with any file, you will maintain visibility into which revisions of your AOLs where deployed, when, where, and by whom.3. Simplify Server Management and Reduce Problems with Automation
Oracle E-Business Suite consists of many different servers, services, and workflows. Each of these components requires different handling to stop, start, restart, enable, or disable. Managing these different server components is not an easy task. Automating server management is censorious for production environments for the following purposes:
Unfortunately, it’s common for IT teams to migrate packages, then find out that they aren’t working with the latest version of the code. Not only is that frustrating, but it too wastes time and extends your software delivery lifecycle.
Instead of struggling to identify which version of the code you’re working with, get reviewing package versions easier by adding a version code perquisite after the header revision comments in your PL/SQL package. This can breathe done manually by the team or by using DevOps tools and continuous processes to ensure this is done each time code is migrated.5. Structure Your Code
All coding – not only packages being readied for migrations – should ensue criterion protocols. The direct here is to get the application’s code as simple and readable as possible. exercise the case office or indent code consistently to get code fragments easy and predictable to read.
Whatever code structure you use, maintain it consistent throughout your organization. Everyone should breathe able to easily view and understand code using the selfsame system.6. Know When to exercise Patch vs. race Edition
Oracle E-Business 12.2 and above comes with editions (Run and Patch). You can deploy your customizations directly to race Edition or apply to Patch Edition (Online Patching) by following ADOP patching phases. Online Patching cycle consists of the following major phases:
Online patching reduces downtime and is too called 0 downtime deployment.
You can deploy changes directly into the race edition. This option should breathe used when changes are diminutive or when the unusual online patching options are not adopted.7. Create Reusable Frameworks
Your IT team doesn’t necessity to disburse time learning unusual development frameworks and standards unless there’s a specific need. So, as you create frameworks to develop your current Oracle applications, breathe positive they can breathe replicated in future implementations.
For example, you can develop a criterion set of 20 inventory categories that ensue a set of naming conventions that can breathe used across projects. exercise these frameworks across teams and with outright your Oracle EBS development tools to create in-house standards that redeem time.8. Reduce Manual, Repeatable Tasks with Idempotent Database Scripts
EBS implementations are composed of great volumes of database objects and PL/SQL programs. infatuation any EBS object, these definitions must breathe synchronized across many environments in your topology. Often, these objects are migrated across environments by the DBA by executing DDL/SQL scripts provided by the development team.
One of the biggest challenges in automating the process is managing updates to existing Oracle database objects. This is pretty simple for objects which maintain CREATE OR supersede objects, but that is not the case for many of the expostulate types (e.g. tables, indexes, sequences, etc.). For example, you cannot execute a create table statement if the table already exists. This is most often managed by writing scripts that are conditional on the situation of the expostulate in the target environment. When it comes to automating the process, this becomes a challenge.
One technique is to create outright DDL/SQL scripts to breathe idempotent, yielding the selfsame result even when applied several times. If you ensue this practice, you can maintain a sole script that is used to apply changes across outright environments, track the revision of the script across environments, and foster healthier relationships between developers and DBAs.
There are different techniques used, which vary by expostulate type. In most cases, however, the scripts must check the current situation and adopt its behavior. For staging tables or stateless objects, simply dropping and re-creating the expostulate is the best passage (taking supervision not to fail if the expostulate does not exist). For stateful objects, such as permanent tables and sequences, you must maneuver insert/update conditions, outright while preserving any state.9. Avoid difficult Coding
Hard code or configure? The selection seems obvious, but it bears repeating: always configure to avoid complications and additional labor down the road.
In times when you feel inclined to allocate values to your code – either strings or numeric – esteem where else you can earn this data. If it’s not available elsewhere, it is best to seize the time to develop custom profile options, descriptive flex fields (DFF) or key flex fields to more effectively itemize categories.10. Automate and Group Tasks Together
Most organizations maintain a few environments for various purposes infatuation development, system testing, performance testing, production, etc. For successful delivery of features to production, it is essential that development teams adopt automation practices.
Automation can breathe employed to carry out various mundane tasks infatuation configuration and code deployment, trait testing, and more. Automation should encourage avoid errors and coerce consistency, which means a reduction in downtime and outages. In cases where tasks necessity to breathe done during late night or weekend hours, automation and scheduling can too encourage ameliorate work-life balance.
As organizations adopt automation, it is a fine design to provide tools for visibility into automated changes to diagnose problems or for audit tracking for various compliance processes. Tools that get it easy to group changes together for promotion may too encourage you manage your EBS software delivery lifecycle that spans anywhere from a few days to weeks or months.Use Standards and Automation to ameliorate Oracle E-Business Suite App Development
Oracle products are highly specialized, and IT teams working on them typically develop their own in-house processes based on guidelines from Oracle and savor with E-Business Suite. Framing that into standards and automating processes to reduce manual, repeatable tasks and nick down on errors can greatly ameliorate app development.
To supplement your in-house processes and best practices, you can too esteem adding DevOps tools with application release automation and other functionality to your IT toolset. These tools will further alleviate the burden of manual labor on your team, helping streamline processes and mainstreaming the best practices that are already in your processes.
