Hi Barbara, Even before I left ASG TMONMVS used supported interfaces for DYNAMIC LPA since OS/390 R4 was GA and also DYNAMIC EXITS on releases where those interfaces are present. It has support to update the SVC (& ESR) table, SMF exits, RACF exits and others while doing the load. He would have to contact ASG for support but I just used this to quickly reload an updated copy of IEFUSI and IEFU29 in the last couple weeks without any difficulty. It is no longer a must have for SMF exits but it does save keystrokes. If I recall it supports a number of exits/modules which are still not enabled by IBM for DYNAMIC EXITS.
TMONMVS and the updated exit itself as well as the IBM interfaces are all suspects because they were found at the scene but if no documentation was gathered (standalone dump, SVC dumps, logrec, syslog would all be useful) and it cannot be replicated then they may never know.

As long as I have used the MVS commands utilizing the dynamic interfaces I never had any problem (other than code problems in the exit itself - which has nothing to do with how they were loaded/defined). It took me some time, though, to really understand the relationship between sys.iefactrt, sysstc.iefactrt, systso.iefactrt and sysjes.iefactrt and how that interacts with the module that gets called for each dynamic exit.
