Mounting Storage Checkpoints using dbed_ckptmount

You can use the dbed_ckptmount command to mount a Storage Checkpoint for the database from the command line.

Before mounting Storage Checkpoints, review the following information:

Prerequisites

You must be logged on as the database administrator (typically, the user ID oracle.)

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

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
