For 10g OIM there was a metalink documentation available for cloning production OIM environment to DR environment. For 11g, however the documentation is not available. I had to do the cloning of 11g environment for a client; the steps performed to accomplish the same are mentioned below:-
For Initial Cloning (Assuming DR is not setup yet)
- Do a fresh install of Weblogic,OIM and SOA and run the respective configuration wizards
- Apply the bundle patches if any are applied to the existing production environment.
- Drop the newly create schema and database users (This step is important).
- Create the user and database tablespaces corresponding to the earlier schemas.
- Update the data sources' DB URL's.
- Update the OIMAuthenticationProvider with correct values for DB URL, username and password.
- Update the Direct DB configuration with correct values for DB URL, username and password.
- Copy the files cwallet.sso,.xldatabasekey,xell.csr,xlserver.cert,default-keystore.jks from the existing production environment to the DR environment
- Update the IT resource information with correct target information using the OIM console.
On a repetitive basis
- Apply the bundle patches if any are applied to the existing production environment.
- Drop the newly create schema and database users.
- Create the user and database tablespaces corresponding to the earlier schemas.
- Update the data sources' DB URL's.
- Update the OIMAuthenticationProvider with correct values for DB URL, username and password.
- Update the Direct DB configuration with correct values for DB URL, username and password.
- Copy the files cwallet.sso,.xldatabasekey,xell.csr,xlserver.cert,default-keystore.jks from the existing production environment to the DR environment
- Update the IT resource information with correct target information using the OIM console.
Patching strategy
- Whatever patches are applied to the OIM in production environment have to be applied to the DR environment separately.
Hope this is useful.
