If you are using the warm standby method, Adaptive Server must know whether it is starting the primary or the secondary server. Use the -q option of the dataserver command to specify that you are starting the secondary server. If you do not start the server with the -q option:
The databases are recovered normally, not as they would be for load database.
Any uncommitted transactions at the time you issue quiesce database are rolled back.
See “Starting the secondary server with the -q option” for more information.
The recovery sequence proceeds differently, depending on whether
the database is marked in quiesce
.
Under the -q option, if a database
is not marked in quiesce
, it
is recovered as it would be in the primary server. That is, if the
database is not currently in a load sequence from previous operations,
it is fully recovered and brought online. If there are incomplete
transactions, they are rolled back and compensation log records
are written during recovery.
User
databases – user databases that are marked in
quiesce
recover in the same manner as databases
recovering during load database. This enables load
tran to detect any activity that has occurred in the primary
database since the server was brought down. After you start the
secondary server with the -q option,
the recovery process encounters the in quiesce
mark.
Adaptive Server issues a message stating that the database is in
a load sequence and is being left offline. If you are using the
warm standby method, do not bring the database online for its decision
support system role until you have loaded the first transaction
dump produced by a dump tran with standby_access. Then
use online database for standby_access.
System
databases – system databases come fully online immediately. The in
quiesce
mark is erased and ignored.
