Mounting Storage Checkpoints Using dbed_ckptmount
You can use the VERITAS Storage Foundation for Oracle dbed_ckptmount command to
mount a Storage Checkpoint for an Oracle database from the command line.
Prerequisites
◆ You may be logged in as either the database administrator or root.
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 DBA user 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. For details, refer to “Mounting the Snapshot
Volumes and Backing Up” on page 241.
◆ See the dbed_ckptmount(1M)manual page for more information.
