probably the most helpful construction techniques are tailor-made to the enterprise and product IT groups are working with. probably the most effectual groups enhance standardized techniques that back chop 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 exist integrated into every IT group. mixed with most dependable practices for each and every team’s technical landscape, it might probably create more effectual tactics that deliver high-quality application to market in less time.
That’s very genuine for IT teams engaged on Oracle apps corresponding to E-business Suite. Combining DevOps practices with inescapable building tips for E-business Suite will execute complete groups greater valuable and produce more desirable consequences for conclusion clients.
At Flexagon, we’ve been assisting IT groups integrate DevOps practices and apparatus into their existing strategies for years – and believe deep potential in Oracle know-how, including E-enterprise Suite. We’ve combined their journey with E-enterprise Suite with widely wide-spread DevOps and evolution most excellent practices to create a list of 10 building assistance for Oracle EBS.
These recommendation will aid developers standardize their tactics, store time, and chop back errors during construction, testing, and deployment to production. They might likewise even execute a contribution to your efforts to truncate the utility mount lifecycle and should extol continuous methodologies like continual integration and continuous birth.most fulfilling Practices for E-company Suite development1. Standardize Naming Conventions
Don’t fritter time naming database objects in response to medium conventions, then the exercise of ad hoc naming for file gadget objects. as a substitute, near up with naming conventions that can exist 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 likewise exist readily understood.2. song AOL changes to your SCM
building groups most commonly implement AOL adjustments in a shared EBS evolution atmosphere. for the understanding 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 confide into your source control equipment.
that you would exist 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 believe visibility into which revisions of your AOLs the region 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 right here purposes:
alas, it’s ordinary for IT teams emigrate packages, then learn that they aren’t working with the newest version of the code. no longer handiest is that irritating, however likewise wastes time and extends your software mount lifecycle.
instead of struggling to establish which edition of the code you’re working with, execute reviewing kit versions less demanding with the aid of including a version code right after the header revision comments in your PL/SQL package. This may likewise exist completed manually via the team or by using DevOps equipment and continuous strategies to execute inescapable here is accomplished every time code is migrated.5. structure Your Code
All coding – no longer handiest packages being readied for migrations – may soundless celebrate ordinary protocols. The smooth right here is to execute the software’s code as simple and readable as possible. exercise the case role or indent code invariably to execute code fragments convenient and predictable to read.
whatever code structure you employ, preserve it constant flawless over your company. everybody may soundless exist in a position to with no pains view and understand code the usage of the identical system.6. exist cognizant 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 likewise known as 0 downtime deployment.
you could set up adjustments without delay into the race edition. This alternative should exist used when alterations are little or when the modern on-line patching alternate options aren't adopted.7. Create Reusable Frameworks
Your IT team doesn’t exigency to spend time getting to know modern construction frameworks and specifications until there’s a particular need. So, as you create frameworks to develop your latest Oracle functions, exist certain they can likewise exist replicated in future implementations.
for example, you could enhance a common set of 20 inventory categories that supervene a group of naming conventions that can exist used across tasks. exercise these frameworks throughout teams and with your entire Oracle EBS evolution tools to create in-apartment necessities that sustain 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 exigency to exist 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 believe 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 protest in the goal atmosphere. When it involves automating the manner, this becomes a challenge.
One technique is to create flawless DDL/SQL scripts to exist idempotent, yielding the identical outcomes even when applied a number of times. in case you celebrate this observe, that you can maintain a separate script it really is used to supervene alterations throughout flawless 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 protest classification. In most cases, youngsters, the scripts exigency to investigate the present situation and undertake its conduct. For staging tables or stateless objects, effectively shedding and re-developing the protest is the most advantageous formula (taking permeate not to fail if the detail does not exist). For stateful objects, akin to permanent tables and sequences, you must deal with insert/replace circumstances, flawless whereas maintaining any state.9. steer transparent of challenging Coding
challenging code or configure? The option appears glaring, however it bears repeating: always configure to obviate problems and further work down the highway.
In times in case you believe inclined to assign values to your code – either strings or numeric – reckon where else you can entangle this records. If it’s not accessible elsewhere, it's most effectual to select the time to strengthen custom profile options, descriptive flex fields (DFF) or key flex fields to extra with no pains itemize categories.10. Automate and neighborhood initiatives together
Most companies believe a pair 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 evolution groups adopt automation practices.
Automation can likewise exist employed to enact a variety of mundane tasks infatuation configuration and code deployment, excellent testing, and more. Automation should soundless back sojourn away from errors and drive consistency, which means a discount in downtime and outages. In instances the region projects deserve to exist performed flawless over late nighttime or weekend hours, automation and scheduling can additionally befriend better work-lifestyles steadiness.
As corporations undertake automation, it is a remarkable understanding to provide tools for visibility into computerized changes to diagnose problems or for audit tracking for a variety of compliance methods. tools that execute it handy to group changes together for merchandising can likewise also befriend 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 chop back guide, repeatable projects and reduce down on errors can vastly better app construction.
To complement your in-apartment tactics and most dependable practices, which you can additionally believe adding DevOps apparatus with software unencumber automation and other functionality to your IT toolset. These apparatus will additional alleviate the burden of usher work in your crew, helping streamline processes and mainstreaming the optimal practices which are already on your tactics.

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 exist covered in detail. They hope that their experiences will befriend you as you undertake your own migrations.
Have you ever wondered about the elements that exigency to near together and align to entangle a complicated database migration right? You might ask, “What makes it complicated?”
Think of any challenge in database migration and pretty much flawless 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 component in any migration and getting it right determines the success or failure of the gross project. The Netflix CDE (Cloud Database Engineering) team was tasked with migrating this censorious subsystem database. The following sections characterize some of key areas they focused on in order to ensure a successful migration.Choice of the database
Billing applications believe transactions that exigency ACID compliance to process the payment for charged transactions. RDBMS seemed the right altenative for the datastore.
Oracle: As source database was in Oracle, migrating to Oracle in Cloud would avoid cross database migration, simplifying the coding application and configuration setup. Their experience 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 believe gone with MySQL RDS as their backend, considering Amazon does a remarkable job in managing and upgrading relational database as a service, providing multi-AZ back for towering 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 believe 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 believe much in house expertise using PostgreSQL. In the DC, their primary backend databases were Oracle and MySQL. Moreover, choosing PostgreSQL would believe 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 altenative for the billing exercise case, since there were no licensing cost and it likewise 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 befriend the billing application withstand infrastructure failures, zone and region outages, and to enact so with minimal downtime.
Using an DRBD copy in another zone for the primary master DB, helped withstand zone outages, infrastructure failures infatuation contaminated nodes, and EBS volume failures. “Synchronous replication protocol” was used to enable the write operations on the primary node to exist considered completed, only after both the local and remote writes believe been confirmed. As a result, the loss of a separate node is guaranteed to believe no data loss. This would impact the write latency, but that was well within the SLAs.
Read replica setup in local, as well as cross region, not only met towering availability requirements, but likewise helped with scalability. The read traffic from ETL jobs was diverted to the read replica, sparing the primary database from hefty 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 modern primary. The billing application being batch in nature is designed to ply such downtime scenarios. The client connection enact not fallback but establish modern connections that would point to the modern primary after the Cname propagation is complete.Choice of Migration Tool
We spent considerable time and application in choosing the right implement for the migration. Primary success criteria for the POC was the talent to restart bulk loads, bi-directional replication, and data integrity. They focused on the following criteria while evaluating a implement for the migration.
GoldenGate stood out in terms of features it offered which aligned very well with their exercise case. It offered the talent to restart bulk loads in case of failures (a few tables were hundreds of GB in size), and its bi-directional replication feature provided facile rollback from MySQL to Oracle.
The main drawback with GoldenGate was the learning curve in understanding how the implement works. In addition, its manual configuration setup is prone to human error, which added a layer of difficulty. If there is no primary key or unique key on the source table, GoldenGate uses flawless columns as the supplemental logging key pair for both extracts and replicats. They found issues infatuation duplicate data at the target in incremental loads for such tables and decided to execute a full 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 implement of choice.Schema Conversion and Validation
Since source and target databases were different, with data nature and data length differences, validation became a crucial step in getting the data migrated while keeping the data integrity intact.
Data nature 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 nature 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 slump beyond 18 digits. One should ensure that reform mapping is done to reflect the accurate values in MySQL.
Partitioned tables needed special handling, since unlike Oracle, MySQL expects the partition key to exist the allotment of the primary key and unique key. Target schema had to exist redefined with proper partitioning keys to ensure no negative impact on application logic and queries.
Default value handling likewise 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 exist enabled in MySQL to entangle such data conversion issues, as such transactions would fail and flaunt up in the GoldenGate oversight 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 work due to their legacy schema design. Even GoldenGate does not convert 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 oversight logs to befriend detect mismatches in data nature mapping between source and target, in order to mitigate this issue.Data Integrity
Once the full load completed and incrementals caught up, another daunting job was to execute certain the target copy correctly maintained the data integrity. As the data types between Oracle and MySQL were different, it was not workable to believe a generic wrapper script to compare hash values for the rowkeys to ensure accuracy. There are a few 3rd party tools which enact the data comparisons across databases comparing the actual values, but the total dataset is 10 TB which was not facile 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 enact 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 befriend with data reconciliation process. Sqoop jobs pulled data out of Oracle for reporting purposes. Those jobs were likewise 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 likewise compared after full 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 befriend of Vector the performance team was able to find bottlenecks and eradicate them by tuning specific system and kernel parameters. descry Appendix for more details.
High performance with respect to reads and writes was achieved by using RAID0 with EBS provisioned IOPS volumes. To entangle more throughput per volume, 5 volumes of 4TB each were used, instead of 1 huge 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 perform well during and after the migration. The main trick is to believe two cnf files, one while migrating the data and tweaking parameters infatuation innodb_log_file_size to befriend with bulk inserts, and the second cnf file for the true time production application load by tweaking parameters infatuation innodb_buffer_pool_instances to befriend with the transaction true time load. descry Appendix for more details.
Data load: During POC, they tested the initial table load with indexes in on/off combination and decided to slump with enabling flawless indexes before the load. The reasoning behind this was that index creation in MySQL is separate 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. singular key constraints were enabled during the final cutover.
Another trick they erudite was to match the total number of processes executing full 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 spend a lot of time in context switches. It took around 2 weeks to populate 10 TB in target MySQL database with the full loads and believe incremental loads entangle up.Conclusion
Though the database piece is one of the most challenging aspects of any migration, what really makes a variation between success and failure is ensuring you are investing in the right approach up front, and partnering closely with the application team throughout the process. Looking back on the gross migration, it was truly a commendable application by different teams across the organization, who came together to define the gross migration and execute the migration a remarkable success! Along with the individual and cross team coordination, it’s likewise the remarkable culture of license and responsibility which makes these challenging migrations workable without impacting business.Appendix Database Tunables for Bulk Insert Database Tunables for towering 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 gross enterprise, it has got some remarkable features.
In the webcast, I focused on the performance management tools within the Oracle Database, which are ASH Analytics and SQL Monitoring. The understanding I was asked to participate is that Oracle Press actually just published a reserve that I wrote on this topic with my colleagues, Michael New and Matthew Burke, titled, “Oracle Enterprise Manager Cloud Control 12c deep Dive.”
Do you exercise Enterprise Manager?
EW: I exercise this technology flawless 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 talent 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 cherish 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 job in life is to sustain 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 remarkable smooth of service for their customers and cessation users.
How did Oracle Enterprise Manager 12c evolve as a product?
EW: The 12c version of Oracle Enterprise Manager actually came out a full 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 believe been out there for awhile and then with version 12c, Oracle named it Cloud Control.
The modern 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 smooth even to the point of allowing you to insulate 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 implement and that is a modern feature that was not available in the earlier versions of Grid Control.
How long believe you been a member of the IOUG?
EW: More than 15 years.
What has your experience been?
EW: I cherish the IOUG. I especially infatuation the IOUG presentations at COLLABORATE because they provide more of the actual down and grimy database administration – really technical information. If you want to learn something about Oracle products and learn about how the DBAs work and what kind of things they race into, you minister to find more about that at COLLABORATE.
What is it that you will exist looking for more information on at Oracle OpenWorld this year?
EW: I am mainly looking forward to getting more information about the modern features in Oracle 12c Database. I likewise work 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 effectual evolution processes are tailored to the company and product IT teams are working with. The most effectual teams develop standardized processes that befriend reduce errors and precipitate up the software delivery lifecycle while increasing efficiency for their specific product.
DevOps spans people, process, and technology, and can exist 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 genuine for IT teams working on Oracle apps such as E-Business Suite. Combining DevOps practices with specific evolution tips for E-Business Suite will execute entire teams more effectual and produce greater results for cessation users.
At Flexagon, we’ve been helping IT teams integrate DevOps practices and tools into their current processes for years – and believe deep expertise in Oracle technology, including E-Business Suite. We’ve combined their experience with E-Business Suite with common DevOps and evolution best practices to create a list of 10 evolution tips for Oracle EBS.
These tips will befriend developers standardize their processes, deliver time, and reduce errors throughout development, testing, and deployment to production. They may even contribute to your efforts to truncate 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 fritter time naming database objects based on criterion conventions, then using ad hoc naming for file system objects. Instead, near up with naming conventions that can exist easily replicated in scripts, executables, reports, forms and more. By taking this approach from the beginning, any out-of-context coding, for sample in a JIRA ticket, can exist easily understood.2. Track AOL Changes in Your SCM
Development teams most often implement AOL changes in a shared EBS evolution environment. Since EBS does not sustain track of revisions of changes, it is best exercise to extract each AOL change to an .LDT and record the revision as a confide 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 believe 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 facile 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 likewise wastes time and extends your software delivery lifecycle.
Instead of struggling to identify which version of the code you’re working with, execute reviewing package versions easier by adding a version code right after the header revision comments in your PL/SQL package. This can exist 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 supervene criterion protocols. The smooth here is to execute the application’s code as simple and readable as possible. exercise the case role or indent code consistently to execute code fragments facile and predictable to read.
Whatever code structure you use, sustain it consistent throughout your organization. Everyone should exist able to easily view and understand code using the identical 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 likewise called 0 downtime deployment.
You can deploy changes directly into the race edition. This option should exist used when changes are little or when the modern online patching options are not adopted.7. Create Reusable Frameworks
Your IT team doesn’t exigency to spend time learning modern evolution frameworks and standards unless there’s a specific need. So, as you create frameworks to develop your current Oracle applications, exist certain they can exist replicated in future implementations.
For example, you can develop a criterion set of 20 inventory categories that supervene a set of naming conventions that can exist used across projects. exercise these frameworks across teams and with flawless your Oracle EBS evolution tools to create in-house standards that deliver time.8. Reduce Manual, Repeatable Tasks with Idempotent Database Scripts
EBS implementations are composed of big volumes of database objects and PL/SQL programs. infatuation any EBS object, these definitions must exist 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 evolution 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 believe CREATE OR supersede objects, but that is not the case for many of the protest 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 relative on the situation of the protest in the target environment. When it comes to automating the process, this becomes a challenge.
One technique is to create flawless DDL/SQL scripts to exist idempotent, yielding the identical result even when applied several times. If you supervene this practice, you can maintain a separate script that is used to apply changes across flawless 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 protest 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 protest is the best routine (taking permeate not to fail if the protest does not exist). For stateful objects, such as permanent tables and sequences, you must ply insert/update conditions, flawless while preserving any state.9. Avoid arduous Coding
Hard code or configure? The altenative seems obvious, but it bears repeating: always configure to avoid complications and additional work down the road.
In times when you feel inclined to assign values to your code – either strings or numeric – reckon where else you can entangle this data. If it’s not available elsewhere, it is best to select 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 believe 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 evolution teams adopt automation practices.
Automation can exist employed to enact various mundane tasks infatuation configuration and code deployment, property testing, and more. Automation should befriend avoid errors and compel consistency, which means a reduction in downtime and outages. In cases where tasks exigency to exist done during late night or weekend hours, automation and scheduling can likewise befriend better work-life balance.
As organizations adopt automation, it is a remarkable understanding to provide tools for visibility into automated changes to diagnose problems or for audit tracking for various compliance processes. Tools that execute it facile to group changes together for promotion may likewise befriend you manage your EBS software delivery lifecycle that spans anywhere from a few days to weeks or months.Use Standards and Automation to better 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 experience with E-Business Suite. Framing that into standards and automating processes to reduce manual, repeatable tasks and chop down on errors can greatly better app development.
To supplement your in-house processes and best practices, you can likewise reckon adding DevOps tools with application release automation and other functionality to your IT toolset. These tools will further alleviate the burden of manual work on your team, helping streamline processes and mainstreaming the best practices that are already in your processes.
