Using Database FlashSnap in an HA environment

Veritas Storage Foundation for DB2 supports Database FlashSnap in the HA environment.

When using Database FlashSnap in the HA environment, observe the following limitations:

To avoid the VCS failover process

  1. As root, temporarily freeze the VCS resource group for the database:

    # hagrp -freeze ResourceGroup
  2. Shut down the primary database.

  3. Run reverse resynchronization:

    # db2ed_vmsnap -D DB2DATABASE -f SNAPPLAN \
    -o reverse_resync_begin
  4. After reverse reynchronization changes are committed (-o reverse_resync_commit), verify that the database has been started in ARCHIVELOG mode. This information is provided in the status messages that appear after running committing reverse resynchronization changes.

  5. Unfreeze the resource group:

    # hagrp -unfreeze ResourceGroup
