I need remedial training in MVS disagnostic techniques. :-( I seem to have combined the concepts of QUIESCE yes/no and SYNCH / ASYNCH. I sort of understand that QUIESCE=YES protects common storage during dump capture by limiting the dispatching of other address spaces (and probably have the details horribly wrong). What does SYNCSVCD do? Something similar with multiple taks within a single address space? I know QUIESCE=YES has caused us all kinds of performance problems in the past so we gone to NO everywhere we could find the option. However, we still are getting synchronous SVC dumps taken. I'm not sure we even have the option of setting that except for SLIP dumps. Is that a problem? <SNIP> At least two places to look: MVS Authorized Services Guide and MVS System Commands discusses the SYNC aspects. QUIESCE is a new one on me, and I can't find anything for such an option with a dump.
