About the sequence of a NetBackup for DB2 restore operation with Snapshot Client methods
For a restore operation, the NetBackup for DB2 agent performs the following tasks:
Using the DB2 database and a point in time, locates the physical backup images.
Disconnects all users from the database (brings the database offline).
Restores the images to the original database.
Uses DB2 APIs to take the files out of the quiesced state, which puts the database in a roll-forward pending state.
Reruns the transactions from the log files (performs the roll-forward operation).
Enables the user connections to the database (brings the database online).
