How Do I Cancel a Print Job in AIX?

To cancel just 1 print job, first identify the job #, by typing the following (We’ll use lp1 as an example):

lpstat -plp1

(make note of the # listed in the “Job” column; we’ll assume it’s “123” for this example)

Type in:

cancel 123

To cancel all print jobs on lp1, type the following:

cancel lp1

To cancel print jobs from the Universe spooler, Find the job # with this command:

usa -j  or usa -p lp1

To cancel one job (i.e. job # 123),  type in

usm -k 123

To delete all jobs in the Universe spooler for lp1:

usm -k -p lp1

How do I schedule a nightly tape backup on AIX?

Traditional tape backups are kicked off by the Eclipse phantom scheduler. The SYS.BACKUP.DVR phantom itself simply executes the /bin/save script, which in turn performs the backup routine and returns a status to Eclipse.

To view/change the nightly backup phantom that runs from within Eclipse:

  • <F2> for System
  • <ALT><A> for Phantom Status
  • <ALT><E> for Schedule
  • Press <Enter> to view all phantoms for all user IDs
  • Select the “System Backup” phantom and press <ALT><E> to Edit
  • When you’ve made the appropriate modifications, press <ESC> to save and exit
For Linux systems, we recommend that you schedule the tape backup and snapshot script simultaneously via crontab, as detailed in this KB article.
