Creating Storage Checkpoints Using sfrac_ckptcreate
- You can use the VERITAS Storage Foundation for Oracle RAC sfrac_ckptcreate command to create a Storage Checkpoint from the command line. Storage Checkpoints can be either online, offline, or instant. See the sfrac_ckptcreate(1M) manual page for more information.If online is specified, the database is put into hot-backup mode when the Storage Checkpoint is created.
- If offline is specified, the database is expected to be down; this is the default.
- If instant is specified, the database is expected to be online; a Storage Checkpoint is taken for a "crash recovery"-type storage rollback.
Usage Notes
In addition to creating the Storage Checkpoint, sfrac_ckptcreate also backs up the Oracle control file in:
$VXDBA_DBPATH/$ORACLE_SID/checkpoint_dir/CKPT_NAME
To create Storage Checkpoints while the database is online
Use the sfrac_ckptcreate command as in the following example:
$ /opt/VRTS/bin/sfrac_ckptcreate -S DB12 \
-H $ORACLE_HOME -o online
NOTICE: Creating online Storage Checkpoint of database DB12.
Storage Checkpoint Checkpoint_1068762379 created.
To create Storage Checkpoints without updating the VxDBA repository while the database is online
Use the sfrac_ckptcreate command as in the following example:
$ /opt/VRTS/bin/sfrac_ckptcreate -S DB12 \
-H $ORACLE_HOME -o online -n
Storage Checkpoint Checkpoint_1068762379 created.
To create Storage Checkpoints while the database is offline
Use the sfrac_ckptcreate command as in the following example:
$ /opt/VRTS/bin/sfrac_ckptcreate -S DB12 \
-H $ORACLE_HOME -o offline
Storage Checkpoint Checkpoint_1068762379 created.
Note
The default option is offline.
