Draining the Spooler
Step 2: Drain the Spooler Properly
To drain the spooler, log on as a super group user (255,n), access SPOOLCOM, and
enter the following command:
SPOOLCOM> SPOOLER, DRAIN
This command causes the spooler to move from the active to the dormant state.
Step 3: Back up the Spooler Control and Data Files
While the spooler environment is closed, you should back up the spooler control and
data files. Backing up the spooler will render a known database from which you can
recover in case of a catastrophic spooler failure.
Steps for Backing Up the Control and Data Files
The following steps describe how to identify and locate the spooler control and
collector data files so that they can be properly backed up.
1. Identify the spooler control and collector data files. If you do not know the location
of the spooler control and collector data files, you can use the following commands
to locate them. If you have multiple spoolers, you will need to follow these
procedures for each spooler.
2. If you do not know the location of the spooler control files (128), perform the
following FUP INFO command:
:
Caution. Do not use the TACL STOP command to bring down the spooler. Also, never use the
TACL STOP command after you have issued the SPOOLCOM DRAIN command. The
warmstartup recovery or rebuild from anything less than a successful drain can be both time
consuming and the rebuild can corrupt the control file. The risk of corrupting the control file is
even more certain if you are migrating from older spooler versions.
Note. During this time when both the Supervisor and spooler processes are dormant, you
cannot obtain any information regarding the configuration of the spooler, that is, the collectors,
the number of devices and print processes that are attached to the Supervisor.
Caution. Do not back up spooler control and data files while they are in the open state. If you
do, the control file could either become corrupt or no longer synchronized with the data file;
and using these files for subsequent recovery and warmstart could lead to serious spooler
problems.
