Journal Sequence Number Qualifiers

These qualifiers are compatible only with /ROLLBACK.

/FET[CHRESYNC]=<port number>

/FETCHRESYNC is used to roll back to the transaction that is identified by a reference point (a JNL_SEQNO) fetched from the primary system. This command rolls back a former primary source server to the journal sequence number at which the then secondary source server (current primary) took over. The <port number> is the communication port number that the rollback command uses while fetching the reference point from the current primary source server.

Note that the <port number> for rollback is the same number used by the receiver server, with which the primary attempts to establish communication.

The reference point sent by the primary system is the RESYNC_SEQNO that the primary source server maintains. The database/journal files are rolled back to the earlier RESYNC_SEQNO (that is, the one received from primary source server , or the one maintained locally).

/RES[YNC]=<journal sequence number>

/RESYNC= is used to roll back to the transaction identified by the journal sequence number, only when the database/journal files need to be rolled back to a specific point. If you specify a journal sequence number that is greater than the last consistent state, the database/journal files are rolled back to the last consistent state. Under normal operating conditions, this qualifier is not needed. Fidelity strongly recommends relying on /FETCHRESYNC, and avoiding the use of the /RESYNC qualifier.
