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 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. 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.

Security

Privilege Control: Only the root user and members of the printq group should have execute (x) access to this command.
