Using Storage Checkpoints and Storage Rollback

Examples of Using the Command Line Interface

Chapter 4

To update the repository

•Use the dbed_update command as follows:

$ /opt/VRTS/bin/dbed_update -S PROD -H /oracle/product/10g

To view the status of the repository

•Use the dbed_update command with the -n option as follows:

$ /opt/VRTS/bin/dbed_update -S PROD -H /oracle/product/10g -n

Repository is up to date.

Creating Storage Checkpoints Using dbed_ckptcreate

You can use the dbed_ckptcreate command to create a Storage Checkpoint from the

command line.

Storage Checkpoints can be either online, offline, or instant. By default, Storage

Checkpoints are offline. 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. If instant is specified, the database must be online and a Storage Checkpoint

will be taken for a “crash recovery”-type Storage Rollback.

Before creating a Storage Checkpoint, the following conditions must be met:

To create Storage Checkpoints while the database is online

Table 4-4 Repository Using dbed_update Notes

Prerequisites You must be logged on as the database administrator (typically, the

user ID oracle).

Usage notes The dbed_update command creates a repository in the

/etc/vx/vxdbed/$ORACLE_SID directory where information used by

SG Oracle RAC is kept. If the repository already exists, the command

will refresh the information.

The database must be up and running, and the ORACLE_SID and

the ORACLE_HOME variable arguments must be specified with the

-S and -H options, respectively.

See the dbed_update(1M) manual page for more information.

Table 4-5 Create Storage Checkpoint Notes

Prerequisites You must be logged on as the database administrator (typically, the

user ID oracle).

For best recoverability, always keep ARCHIVELOG mode enabled

when you create Storage Checkpoints.

Usage notes dbed_ckptcreate stores Storage Checkpoint information under the

following directory:

/etc/vx/vxdbed/$ORACLE_SID/checkpoint_dir

See the dbed_ckptcreate(1M) manual page for more information.
