sashton,
We use ROBOT on our AS/400 and it is a nice scheduler. Unfortunately if you use it you will get NO support for any UBE's that fail. We have been arguing this with JDE/PeopleSoft for as long as we have been on OW (4 years now). When using any scheduler, be carefull that you don't submit 2 or more UBE's at the same time. There is a bug in a JDE kernel function that sometimes allows duplicate run numbers. When this happens the 2nd job to actually run fails. We find the occurance of this failure is about once every 10K-20K jobs, since we put through about 60K jobs a day we get 4-5 failures every 24 hours. JDE will only support you if you use RUNUBE from the command line. Since this is a timing problem, your chances of duplicating the problem manually are minimal.
