Examples of Using the Command Line Interface

Chapter 4

To mount Storage Checkpoints with the read/write option

•Use the dbed_ckptmount command as follows:

$ /opt/VRTS/bin/dbed_ckptmount -S PROD -c Checkpoint_971672042 \

-m /tmp/ckpt_rw -o rw

Creating Storage Checkpoint on /tmp/ckpt_rw/share/oradata with name

Checkpoint_971672042_wr001

To mount Storage Checkpoints with the read-only option

•Use the dbed_ckptmount command as follows:

$ /opt/VRTS/bin/dbed_ckptmount -S PROD -c Checkpoint_971672042 \

-m /tmp/ckpt_ro -o ro

Unmounting Storage Checkpoints Using dbed_ckptumount

You can use the dbed_ckptumount command to unmount a Storage Checkpoint for an

Oracle database from the command line.

Before unmounting Storage Checkpoints, the following conditions must be met:

Usage notes The dbed_ckptmount command is used to mount a Storage

Checkpoint into the file system namespace. Mounted Storage

Checkpoints appear as any other file system on the machine and can

be accessed using all normal file system based commands.

Storage Checkpoints can be mounted as read-only or read-write. By

default, Storage Checkpoints are mounted as read-only.

If the rw (read-write) option is used, _wrxxx, where xxx is an

integer, will be appended to the Storage Checkpoint name.

If the specified mount point directory does not exist, then

dbed_ckptmount creates it before mounting the Storage Checkpoint,

as long as the Oracle database owner has permission to create it.

Database FlashSnap commands are integrated with Storage

Checkpoint functionality. It is possible to display and mount Storage

Checkpoints carried over with snapshot volumes to a secondary

host. However limitations apply.

See “Mounting the snapshot volumes and backing up” on page 408.

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