Mirror Replication Agent for Oracle migration to support upgrading Oracle 9i to Oracle 10g is a process similar to upgrading Mirror Replication Agent for Oracle 12.6 or 15.0 to Mirror Replication Agent 15.1.
Verify that the Mirror Replication Agent is quiesced
prior to upgrading Oracle 9i to Oracle 10g, that is, the replication
environment must have completed processing of all transactions prior
to upgrading Oracle because the Mirror Replication Agent moves the
truncation point to the end of the log during Mirror Replication
Agent migration.
To migrate from Oracle 9i to Oracle 10g
Follow the steps that Oracle provides in their documentation for upgrading from Oracle 9i to Oracle 10g.
After upgrading Oracle, you must restart the Mirror Replication Agent and issue the ra_migrate command.
As with the log-based Mirror Replication Agent upgrade, you may have to re-configure the Mirror Replication Agent for Oracle instance to read archive logs depending on the configuration in Oracle. This may change following the Oracle upgrade.
If you are upgrading from log-based Mirror Replication Agent and upgrading Oracle 9i to Oracle 10g at the same time, you need to migrate Mirror Replication Agent 15.1 only once.
