Hi Mark,
In respect of your VSAM close giving RC=4. I am not a VSAM expert so the
following may be off beam, but I remembered this quote from the Data Set Macros
Manual.
"Requirement: If you are sharing subtasks or if you have issued an asynchronous
request for access to a data set, you must issue a CHECK or an ENDREQ on all
RPLs before you issue a CLOSE or CLOSE TYPE=T. Otherwise, concurrent data set I/O
activity causes unpredictable results during a close."
I wondered if the above fits with your question?
"Is there any IO call that would/could/should leave the ACBBUSY flag set when it returns? It would seem that this is the most obvious difference between all the ACBs."
Kind Regards - Terry
Terry,
I'm doing SYNC IO requests. So CHECK should not be needed.
I've tried the ENDREQ approach with no change in the results.
Thanks for the ideas though.
