After you have completed downgrading the RSSD using the rs_init, your connection to Oracle data server (if your connection to Oracle is created using the create connection with using profile clause) may be down because the wait_after_commit configuration parameter provided in Replication Server 15.5 is no longer available. To resume your replication:
Execute:
alter connection to data_server.database set dsi_serialization_method to 'wait_for_commit' go
Resume log transfer to active database.
Resume Replication Agent for Oracle.
After you have completed performing these above steps, you can start replicating from active database to other replicate database with the replication definitions and subscriptions created before downgrade.
After downgrading, the Oracle standby connection will
be broken as it is not able to do function string mapping or data
translation. If you did not drop standby connection before downgrading
the RSSD, you can drop it after the downgrade.
