You can back up a database by creating a Storage Checkpoint using the dbed_ckptcreate command, mount the Storage Checkpoint as read-only using the dbed_ckptmount command, and then back it up using tools such as tar or cpio.
See the dbed_ckptcreate(1M), dbed_ckptmount(1M), tar(1), and cpio(1) manual pages for more information. |
See Creating Storage Checkpoints using dbed_ckptcreate
See Mounting Storage Checkpoints using dbed_ckptmount
In the example procedure, all the database datafiles reside on one VxFS file system named /db01.
To back up a frozen database image using the command line
dbed_ckptcreate
command:
$ /opt/VRTS/bin/dbed_ckptcreate -S PROD -H /oracle/product \
dbed_ckptmount
command:
$ /opt/VRTS/bin/dbed_ckptmount -S PROD -c Checkpoint_903937870 \
If the specified mount point directory does not exist, then dbed_ckptmount creates it before mounting the Storage Checkpoint, as long as the Oracle DBA user has permission to create it.
