DESCRIPTION



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. 





OPTIONS



The following options are supported:





-S ORACLE_SID





Specifies the name of the Oracle database for which a Storage Checkpoint will be mounted.





-c CKPT_NAME





Specifies the name of the Storage Checkpoint to be mounted. This Storage Checkpoint
should have been created using the dbed_ckptcreate command.





-m MOUNT_POINT





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.





-h





Shows command usage. 









EXAMPLES



This example shows how to mount a Storage Checkpoint with the 
read/write option:





$ /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

Creating Storage Checkpoint on /tmp/ckpt_ro/share/oradata_816 
with name Checkpoint_971672042_ro001














NOTES



dbed_ckptmount
can be run as either the Oracle DBA user or the superuser.
