Storage Checkpoint configuration on the NetBackup for DB2 client

By default, the NetBackup for DB2 with Snapshot Client for proxy BLI backups uses the Fulldata Storage Checkpoint. When Fulldata Storage Checkpoint is in effect, the NetBackup for DB2 agent keeps the DB2 database quiesced. The database is quiesced (write suspend) only for the time that is needed to create a Storage Checkpoint.

To change the default option to use Nodata Storage Checkpoint, a user must create the following file, which can remain empty:

    /usr/openv/netbackup/ext/db_ext/NODATA_CKPT_PROXY

If the agent finds this file during run time, it uses Nodata Storage Checkpoint, and it keeps the database containers in quiesced (write suspend). The database containers are kept in this mode for the duration of the backup.
