Operating Systems HP-UX Old crontab file reflected after server reboot Post 302703019 by vbe on Wednesday 19th of September 2012 09:08:25 AM
Old 09-19-2012
Exactly: when a server reboots, it reloads what is in /var/spool/cron/crontabs/ You should never leave anything unused in there... It is not to say you should delete without taking any precaution... I create a .save (as root and 750) directory one level above and mv what is unwanted in .save, the same I historize the cron files also in case of corruption or disagreement with production e.g. How come this job never finish when it used to? If you can prove someone changed the schedule, your out of trouble...
This is important to be done when you are going through a upgrade/update process where you risk rebooting a few times during one-two days : MOVE all cron file out or /var/spool/cron/crontabs while in maintenance!

NAME
bcrontab - Manage users crontab files SYNOPSIS
bcrontab [ -u user ] file bcrontab [ -u user ] { -l | -r | -e } DESCRIPTION
bcrontab interfaces with the bcron-spool daemon to manage crontab files in the privileged spool directory. OPTIONS
-u user Tell bcron-spool that we are acting on behalf of the named user. bcron-spool will only accept the username if bcrontab is running as either root or the same user ID as the named user. -l List the cronab crontab to standard output. -r Remove the user's crontab. -e Edit the current crontab. ENVIRONMENT
VISUAL If this is set, it is used as the editor to invoke to edit a crontab. EDITOR If $VISUAL is not set and this is, it is used as the editor to invoke to edit a crontab. If neither are set, /bin/vi is used. BCRON_SOCKET The path to the named socket used to communicate with bcron-spool. Defaults to /var/run/bcron-spool. LOGNAME USER These two variables are used, in order, to determine the user name invoking the program. One must be set if the -u option is not used. FILES
bcrontab tries to writes a temporary file into the current directory, and then into /tmp if that fails, in order to edit the current crontab. SEE ALSO
