Certificates used by OUD for Replication


I wonder what's the best way to replace the self-signed certificate OUD uses to encrypt replication data. My client feels uneasy with the fact that OUD creates its own certificates for replication, and even if we leave them as-is you'd still have an issue because you have to keep track of the expiration date. There's an article in Oracle Support that explains in detail how to force OUD to generate a new self-signed certificate (1619734.1) but I'd like to know if I can insert my own certificate.

    In R2PS2, this is quite complex to manage as key/trust stores must be modified and corresponding pieces of information stored in cn=admin data must be updated as well.

    I'm not allowed to elaborate more on that yet, but expect significant progresses in Certificate management for replication in the coming OUD version (R2PS3).

    I just read through the release notes for OUD 11gR2PS3 but I do not see anything with regards to Certificate Management for replication.  Can you elaborate on the improvements in this release, or were those improvements pushed off to a future release?  I have managed to successfully replace the replication certificates but as you alluded to earlier, it is not exactly a clean process and doesn't seem supported.  Our upgrade/migrations are being held up by many issues with OUD, and this is one of the big ones.  Until there is a documented and supported means of changing this self-signed certificate I cannot proceed with moving to OUD.

    Edit:  I read through some more of the documentation and now see the new "Replication Certificate Management" management sub command of the dsreplication command.

    By the way, your responses here and on your blog are extremely helpful and appreciated.

    We've tested the commands in our sandbox and they look good. Looking forward to upgrade the certificates in production once we get all the instances patched to
