qdaemon的详解https://www.ibm.com/support/knowledgecenter/ssw_aix_71/com.ibm.aix.cmds4/qdaemon.htm
qdaemon Command
Purpose
Schedules jobs enqueued by the enq command.
Syntax
qdaemon
Description
The qdaemon command is a background process (usually started by the startsrc command) that schedules printing jobs enqueued by the enq command.
Recommendation
If manual editing of the /etc/qconfig file is necessary, you can first issue the
enq -G command to bring the queuing system and the
qdaemon to a halt after all jobs are processed. Then you can edit the
/etc/qconfig file and restart the
qdaemon with the new configuration.
To edit the /etc/qconfig file, use the
chque,
mkque, rmque,
chquedev, mkquedev, and
rmquedev commands or SMIT. Further, it is recommended to run these commands during slow or off-peak time.
Security
Privilege Control: Only the root user and members of the printq group should have execute (x) access to this command.
