Post Clone Steps In Oracle Applications

Post Clone Steps In Oracle Applications

The cloning process has traditionally been a manual process performed by DBAs. This process involves copying over the database files – preferably using RMAN DB duplicate, the tech stack, and the application tier to the non-production servers, converting them to DEV or TEST, and then performing a number of post clone steps such as disabling workflow emails from going to end users, scrambling financial information, updating the clone date and the instance name within the apps heading, editing the custom top, changing passwords, and others.  Depending upon the size and configuration the cloning process can take from 12 hours to 48 hours on average.

The number of post clone steps can get to be quite numerous and even with the best of documented procedures; one or two steps can easily be missed.

Note:-  the following is a list of steps in one particular cloning environment, It may vary based on environment.

1. Once the cloned database is renamed, add all the temp datafiles to the TEMP tablespace.

2. All key passwords need to be updated from their production values to the appropriate values for the DEV environment. (ie: sys,system, sysadmin,apps)

3. Custom database directories need to be re-created with the correct paths for the DEV server.

4. Specific Profile options need to be re-defined – like the apps heading naming the instance and the date stamp of the clone.

5. End-dating specific users so that only the desired developers have access to the instance.

6. Removing/scrambling specific private HR data.

7. Nulling out specific email addresses to prevent workflow from emailing end-users from the DEV instance.

8. Putting a hold on all regularly scheduled production concurrent requests in the DEV instance.

9. Updating all profile option values, swapping out the prod instance name for the DEV instance name. Additional updates for the server names also run.

10. Updates for all custom environment code paths and settings.

11. Updates for any and all printer setting changes.
