The following example shows the crontabs entries on a control workstation:
0 * * * * /usr/lpp/ssp/bin/dev/null 2>/dev/null 0 0 * * * /usr/lpp/ssp/bin/cleanup.logs.ws 0 4 * * 1-6/usr/lpp/ssp/bin/crunacct 2>/var/adm/cacct/nite/accterr 15 5 1 * * /usr/lpp/ssp/bin/cmonacct
The default is to run these processes hourly, in a staggered sequence. You can customize this for your environment to make any of these processes run more or less frequently. You can also add your own entries to these files for other processes you want automated.
