Storage Checkpoints provide a frozen image of the datafiles in an Oracle database. Online and offline Storage Checkpoints do not provide frozen images for database control files or online redo log files. dbed_ckptcreate does, however, ensure that a backup control file is created when the Storage Checkpoint is created to allow for complete recovery, if required.
For instant Storage Checkpoints, frozen images for datafiles, control files, or online redo log files are provided. Only database-level recovery is allowed for instant Storage Checkpoints. Individual datafiles and tablespaces cannot be rolled back. In addition, rolling the database forward is not allowed for instant Storage Checkpoints (that is, you cannot apply archived redo logs).
Frozen database images can be used for data recovery in the event of logical data corruption in the database and for mounting and backing up frozen images. They can also be cloned and made writable for online modification (such as investigative work and debugging).
- online | offline | instant
- Specifies the expected behavior at Storage Checkpoint time for the database. If online is specified, the expected behavior is to create a Storage Checkpoint by putting the database into hot-backup mode. If offline is specified, the database is expected to be down. If instant is specified, the database must be online and a Storage Checkpoint will be taken for later data recovery. The default option is offline.
- remove | noremove
- Specifies the behavior of the file system when it runs out of space. By default, when a file system containing Storage Checkpoints runs out of space, the older Storage Checkpoints are removed to allow operations to proceed on the main file system. If it is critical to maintain the Storage Checkpoint even if the file system it resides on is out of space, specify the noremove option.
$ /opt/VRTS/bin/dbed_ckptcreate -S PROD -H /oracle/product/9i -o online NOTICE: Creating online Storage Checkpoint of database PROD. Storage Checkpoint Checkpoint_971672042 created.
This example shows how to create a Storage Checkpoint while the database is offline:
$ /opt/VRTS/bin/dbed_ckptcreate -S PROD -H /oracle/product/9i -o offline NOTICE: Creating offline Storage Checkpoint of database PROD. Storage Checkpoint Checkpoint_971672044 created.
This example shows how to create an instant Storage Checkpoint:
$ /opt/VRTS/bin/dbed_ckptcreate -S PROD -H /oracle/product/9i -o instant NOTICE: Creating instant Storage Checkpoint of database PROD. Storage Checkpoint Checkpoint_971672045 created.
This example shows how to assign a Storage Checkpoint allocation policy to Storage Checkpoint data and metadata:
$ /opt/VRTS/bin/dbed_ckptcreate -S PROD -H /oracle/product/9i -o online -p ckpt_data_policy,ckpt_metadata_policy Creating online Storage Checkpoint of database PROD. Storage Checkpoint Checkpoint_971672044 created.
Use the -i option if you want to be prompted before critical actions are taken. If you are using this command for the first time, it is recommended that you use the -i option.
