Storage Checkpoint configuration on the NetBackup for SAP client
By default, the NetBackup for SAP with Snapshot Client for BLI backups uses the Fulldata Storage Checkpoint. When Fulldata Storage Checkpoint is in effect, the NetBackup for SAP agent keeps the Oracle data files in backup mode. The Oracle data files are kept in backup mode 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 data files in backup mode. The data files are kept in backup mode for the duration of the backup.
