Anyone have any ideas? David Dobbins [log in to unmask] Hi David, If you're on 5.0, there is a patch, MPEHXD7 that addresses this issue. It has been superseded by MPEHXP7, which is available either separately or as part of the C.50.04 Powerpatch. I think that Larry (Spoolers-R-Us) Byler explained the issues with having a very large number of linked output spoolfiles in a post here a while ago; basically you'll take a performance hit on some spooler commands and on START RECOVERY if the number of spoolfiles is extremely large. These considerations are probably what prompted the choice of 10000 (more or less) as the limit for linked output spoolfiles. Considering that the prior limit (before NMS) was about 600-800, it must have seemed like enough at the time. There are two SRs that you might look for if you have HPSL: 5003258970 and 5003009324. Otherwise (or actually, in any case), you can place a response center call and get the patch/powerpatch and more info on this. Hope this helps, Jeff (oh for the days when ALTFILE was a spooler command) Flowers << as usual, these opinions are mine alone >>
