Using the Target Database as a Read-only Copy
The target database may be used as a read-only copy with a couple of limitations:
• Sessions connecting to the target database will acquire a lock that will prevent the incremental rollforward of the journals. This means, the jnlsync operation will fail and the target database will become outdated. However, it will pick up once the jnlsync operation is able to proceed.
• Sessions using MVCC lock_mode may encounter errors, such as
E_US125A Insufficient undo information to make read consistent page. Full MVCC access is only guaranteed after the target has been taken out of INCR_RFP mode using the incremental_done operation. See
