Distributed App. Server Backup

Question

I have:
machine1-Identity Management(OID,SSO)
machine2-Middle Tier(portal,forms,reports)
machine3&4-Metadata Repository in RAC database
I want to know how to backup the App. Server Environment. In most documentation, it assumes that the Metadata Repository is on the same machine as Identity Management and when this is the case, the backup tool will automatically backup the Identity Management config and the Metadata Repository datafiles.
Since I do not have this configuration, how can I backup the Metadata Repository, Identity Management and Middle Tier. I figure I need to do the backups very close to each other timewise and that this is the order I should do them in. I am afraid that if I just schedule a RMAN backup of the RAC database at a different time than the App. Server backups that they could be inconsistant. Any suggestions?? Thanks.

Answer 1

You can run the tool in the MR Oracle home, the Identity Management
Oracle home, and the middle tier Oracle home. The order doesn't matter,
and, yes, you should do these as close together as possible and not
make any administrative changes until all backups have completed.
We will update future documentation to make this clear.
Thanks!
