Prerequisites
• You must log in as the database administrator to use the following CLI commands.
— dbed_update
— dbed_ckptcreate
— dbed_clonedb
• You can log in as the database administrator (typically, the user ID oracle) or superuser to
use the following CLI commands.
— dbed_ckptdisplay
— dbed_ckptmount
— dbed_ckptumount
— dbed_ckptrollback
— dbed_ckptremove
Creating or Updating the Repository Using dbed_update
You can use the dbed_update command to create or update the repository.
Any time you change the structure of the database (for example, by adding or deleting datafiles,
converting PFILE to SPFILE, or converting SPFILE to PFILE), you must run dbed_update.
Before creating or updating the repository, the following conditions must be met:
Table 4-4 Repository Using dbed_update Notes
You must be logged on as the database administrator (typically, the user ID oracle).Prerequisites
The dbed_update command creates a repository in the /etc/vx/vxdbed/$ORACLE_SID
directory where information used by SGeRAC 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.
Usage notes
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:
