It would have avoided a recent problem we had with Compuware's LMS after we upgraded to V3. Their "LMSEXIT" STC updates license information in a shared VSAM control file (the file doesn't have to be shared) on multiple LPARs and kicks off at the same time on all LPARs. Of course this led to problems. We did resolve the problem by adding an undocumented QNAME to MII after talking to Compuware support. I've probably not run into issues with PROCESS=SELECT at this shop or others in the past because most products that issue special ENQs or RESERVES document them in their installation guides or at least their system programming guides. RESERVEs are not an issue regardless of the PROCESS= setting. You can always find the ones your not processing with a DISPLAY COUNTS command.
