Updating a warm standby Sybase ASE 12.5 database
If you specified the for external dump clause when you quiesced the primary
database, and you started the replica database by specifying the -q option to the
dataserver command, you can use transaction logs to update the replica database.
To update the replica database
1
On the primary host, use the following isql command to dump the transaction
log for the database:
dump transaction to dump_device with standby_access
Copy the transaction log dump to the appropriate database directory on the
OHP host.
2
On the OHP host, use the following isql command to load the new transaction
log:
load transaction from dump_device with standby_access
3
On the OHP host, use the following isql command to put the database online:
online database database_name for standby_access
Reattaching snapshot plexes
Some or all plexes of an instant snapshot may be reattached to the specified
original volume, or to a source volume in the snapshot hierarchy above the
snapshot volume.
Note: This operation is not supported for space-optimized instant snapshots.
By default, all the plexes are reattached, which results in the removal of the
snapshot. If required, the number of plexes to be reattached may be specified as
the value assigned to the nmirror attribute.
Note: The snapshot being reattached must not be open to any application. For
example, any file system configured on the snapshot volume must first be
unmounted.
