Rackspace best practices to clone a PeopleSoft environment
by Gaurav Sehgal, Manager, Application Support, Rackspace Technology
Refreshing a PeopleSoft® non-production environment with your production environment can become a monthly, weekly, or even daily activity, depending on the business needs.
For some, refreshing an environment can be such an ordeal. Not having updated data to test issues and develop can lead to potential problems, especially when you do not regularly refresh your non-production instances with production.
The following image shows a typical PeopleSoft Environment:
A single PeopleSoft environment typically consists of thousands of relational database tables, indexes, and views, with the delivered DEMO and SYS environments created with the Data Mover tool. You usually create all other environments
(Development, Test, Quality Assurance, Production, and so on) by cloning or copying an existing environment to a target.
RMAN Backup/Restore is one of the several methods available to clone or copy PeopleSoft databases. Using the RMAN method, you restore a full backup of the source database over the target database. After the restore, you need to edit
some PeopleSoft tables to reflect the new database name, new server location, and so on.
The Rackspace procedure
Rackspace has expertise in performing clones of the PeopleSoft environment and applies the following method, which involves using customized scripts to refresh any environment.
In the following example, we want to refresh the TEST (target) database from the PROD (source) database.
1. Make sure there is enough space in the source backup directory. Back up the source database, and check the log file for any errors after the backup completes.
2. Move the backup files of the source database backup to the target machine.
3. Take pre-refresh export backups of the target database before dropping it and
restoring the source database backup. Perform these exports to ensure that
you don't lose any critical TEST data during the refresh activity.
4. Take a backup of the dblinks, security, roles, PIA users, and projects, if
any, from the target database, which you want to restore.
5. Conduct any other customer-specific pre-refresh tasks that are necessary.
6. You can also take an export of some tables, including the integration broker
settings, report nodes, REN server, and SSL, if implemented. Following are
some of the listed tables:
- Gateway and Node tables: PSGATEWAY, PSCONN, PSCONNPROP, PSMSGNODEDEFN, and so on
- Web Profiles: PSWEBPROFBROW, PSWEBPROFCOOK, PSWEBPROFILE, and so on
- SSL Certificates: PSCERTDB
- Report Nodes: PS\_CDM\_DIST\_NODE, PSSERVERSTAT, and so on
- REN SERVER: PSREN, PSRENCLUSTER, and so on
7. Perform the restore. Rackspace has developed scripts and procedures that drop the target database (TEST) and replace it with the source database (PROD). After the target is up and running again, you can continue with the post
8. Import the dblinks, database users, security, roles, PIA users, and projects to the target database.
9. You need to edit some of the PeopleSoft tables on the target database to reflect the new (TEST) database name, new server location, and so on. You can also run the import of the tables that you exported in step 6 or manually do the changes online related to nodes, report nodes, integration broker, and the REN server.
- Complete the PeopleSoft environment settings.
- Update the REN server settings.
- Validate or update the integration broker settings.
- Validate or update the Elastic Search® or SES settings.
10. Perform any necessary customer-specific post-refresh tasks.
11. Do a sanity check and release the environment to the client.
As you can see, with our Rackspace expertise and experience, you can easily refresh your PeopleSoft environment. Many of the steps involved require no manual intervention, and you automate them fully. This helps to minimize downtime in a non-production environment. Rackspace also provides flexibility so you can adhere to your existing business practices and customize the refresh process to exceed your expectations.
