Your question is confusing as phrased. Do you mean that a job is running, but is taking too long? Or do you mean that there are jobs in the INPUT queue, not running, and there are initiatiators available which should service the class that the jobs are set to run in? If they are "running too long", then I'd __guess__ that perhaps the CPU is overloaded or that they are waiting on a resource. Use SDSF DA to see if they are getting any CPU% at all. If the POS column says something LW or DW, then they are waiting for something. I'd enter the operator command: D GRS,C to see if there are any enqueue conflicts. If the POS column has IN, but the CPU% is 0 or very small, your CPU may be overloaded and the job is not getting sufficient CPU cycles. Another possibility is that WLM is set up incorrectly and is denying service to the jobs. But this would require looking in an RMF type display to determine. If the jobs are in the INPUT queue and there are idle initiators servicing that job class, make sure that the jobs in question are not affinitied to some other z/OS system. In the SDSF I display, look in the SAFF column to see if the jobs are affinitied to a system which is unavailable or which does not have an available initiator for the job's execution class. Also, if you use WLM Scheduling Environments, it is possible that the job has a dependancy on one of them and no system has that environment marked as "active". I don't know how many shops use WLM Scheduling Environments. We don't. -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.
