Veritas Storage Foundation for Oracle.
To determine whether this product is installed on an \1 system, enter:
lslpp -L VRTSdbed
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.
Database FlashSnap commands are integrated with Storage Checkpoint functionality.
It is possible to mount a Storage Checkpoint carried over with snapshot volumes
to a secondary host. However, limitations apply. For details, see the dbed_vmclonedb(1M)
man page or the Veritas Storage Foundation for Oracle Administrator's Guide.
The following options are supported:
Specifies the name of the Oracle database for which a Storage Checkpoint will be mounted.
Specifies the name of the Storage Checkpoint to be mounted. This Storage Checkpoint
should have been created using the dbed_ckptcreate command.
Mounts the Storage Checkpoint under the named directory.
If the directory
does not exist, then dbed_ckptmount creates it before mounting the
Storage Checkpoint, as long as the instance has permission to create it.
-o ro | rw
Specifies read-only or read-write for mounting the Storage Checkpoint.
By default, all Storage Checkpoints are mounted read-only. Mounting a
Storage Checkpoint read-write requires creating a shadow Storage Checkpoint
against the existing read-only one to ensure that the frozen image is
preserved. Thus, the mounted Storage Checkpoint name will be
different than the one named on the command line if the rw option
is used. \_wrxxx, where xxx is an integer, will be appended to the Storage Checkpoint
name if it is mounted as read-write.
Shows command usage.
This example shows how to mount a Storage Checkpoint with the
$ /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_816
with name Checkpoint_971672042_wr001
This example shows how to mount a Storage Checkpoint with the read-only option:
$ /opt/VRTS/bin/dbed_ckptmount -S PROD -c Checkpoint_971672042 -m /tmp/ckpt_ro -o ro

with name Checkpoint_971672042_ro001
can be run as either the Oracle DBA user or the superuser.
