Veritas Storage Foundation 5.1 SP1 Advanced Features Administrator"s Guide (5900-1503, April 2011)

If you temporarily suspended updates to volumes in step 3, perform the

following steps.

Release all the tablespaces or databases from suspend, hot backup, or quiesce

mode:

■ As the DB2 database administrator, use a script such as the example script.

See “Script to resume I/O for a DB2 database” on page 518.

■ As the Oracle database administrator, release all the tablespaces from hot

backup mode using a script such as the example script.

See “Script to end Oracle database hot backup mode” on page 517.

■ As the Sybase database administrator, release the database from quiesce

mode using a script such as the example script.

See “Script to release a Sybase ASE database from quiesce mode”

on page 517.

If you are using Sybase ASE 12.5, you can specify the for external dump

clause to the quiesce command. This warm standby method allows you

to update a replica database using transaction logs dumped from the

primary database.

See “Updating a warm standby Sybase ASE 12.5 database” on page 192.

For each snapshot volume containing tablespaces, check the file system that

it contains, and mount the volume using the following commands:

# fsck -F vxfs /dev/vx/rdsk/diskgroup/snapvol

# mount -F vxfs /dev/vx/dsk/diskgroup/snapvol

mount_point

For example, to check the file system in the snapshot volume

snap1_dbase_vol, and mount it on /rep_dbase_vol:

# fsck -F vxfs /dev/vx/rdsk/dbasedg/snap1_dbase_vol

# mount -F vxfs /dev/vx/dsk/dbasedg/snap1_dbase_vol \

/rep_dbase_vol

Copy any required log files from the primary database to the replica database.

■ For an Oracle database, copy the archived log files that were generated

while the database was in hot backup mode to the new database’s archived

log directory (for example, /rep_archlog).

■ For a Sybase ASE database, if you specified the for external dump clause

when you quiesced the database, use the following isql command as the

database administrator to dump the transaction log for the database:
