Table 4-8 Mounting Storage Checkpoints Notes
You may be logged in as either the database administrator or superuser.Prerequisites
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.
Usage notes
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:
Table 4-9 Unmounting Storage Checkpoints Notes
You may be logged in as either the database administrator or superuser.Prerequisites
The dbed_ckptumount command is used to unmount a mounted Storage Checkpoint from
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. When mounted
Storage Checkpoints are not required, they can be unmounted.
See the dbed_ckptumount(1M) manual page for more information.
Usage notes
To unmount Storage Checkpoints
• Use the dbed_ckptumount command as follows:
# /opt/VRTS/bin/dbed_ckptumount -S PROD -c Checkpoint_971672042_wr001
Performing Storage Rollback Using dbed_ckptrollback
You can use the dbed_ckptrollback command to rollback an Oracle database to a Storage
Checkpoint.
Before performing a Storage Rollback, the following conditions must be met:
