Problem summary
**************************************************************** USERS AFFECTED: Problem seen when multiple jobs are started at the same time with cron on AIX **************************************************************** PROBLEM DESCRIPTION: When multiple jobs are scheduled with cron to start at the same hh:mm, one may fail to start. The Director job will show one line with DS.SCHED: Started at... but nothing more. The cron log will show that a particular pid failed. This problem has thepotential of happening on any UNIX platform but has only been reported against AIX at this point. **************************************************************** RECOMMENDATION: 5.2 is available. This change is included in 8.1 Fix Pack 1. ****************************************************************
Problem conclusion
The customer's problem is caused by the attempt to use the same shared memory segment to start each scheduled job. Setting the environment variable DSE_PID_SIGNATURE in $DSHOME/dsenv to 1 will result in generating a more unique shared memory segment key.
