Under normal operation, the Alternate Buffer Pool (-B2) parameter may be designated to help improve database performance by offloading objects or areas from the primary buffer pool.

Online failover transition changes the -B2 parameter during failover transition to behave as follows:

  • -B2 will be disabled on a replication target database.
  • After online failover transition,-B2 will be disabled on the new target database no matter it was enabled or not on the original source.
  • -B2 will be disabled on the new source database. To enable -B2 on the new source, that database must be shut down and restarted with the -B2 parameter designated.
