You Asked

Our customer insists that the metadata repository of WebLogic Server be deployed into PDBs of their production, multitenant, 12c database. I have always thought that the metadata for products such as OUD, OBIEE, etc. should be deployed to a separate database, on a separate server, in a separate security zone from the production database.

I am beginning to believe that this separation has never been necessary because I have pored over documentation and MOS articles looking for guidance and have found none one way or the other. So, could you advise me about this? Is it acceptable/advisable to deploy WLS repository data into PDBs of the same CDB as the production PDB?

Cheers,
Russ

A PDB can give the same level of isolation as separate databases. Its one of the reasons the architecture was built this way. Obviously if you choose to create cross-container admin users, then they can access data across containers - but that would be something you have done *explicitly* - we don't do it by default.

I would view separation of things OUD, OBIEE, WebLogic to fall under the same decision making process as any database you have in your organization, for example:

- availability/performance requirements
- any db version restrictions/dependencies or certification issues
- if a product explicitly cannot run in a pluggable
- anticipated patch frequency requirements
etc
