TS QUEUE deleted at start of the program

Postby apjohn1986 » Mon May 15, 2017 12:29 pm

One of the CICS program is failing in production(not all the time, only on few scenarios). As per Dump, it seems like TS Queue is deleted before the execution of 'EXEC CICS READQ TS QUEUE'.

I am new to CICS. Can one you please explain possible scenarios where TS Queue deleted before program execution.
Thanks,
John

a dump of the CURRENT transactions will just tell < generally> that the TS queue does not exist,nothing about its history,
unless You find an entry in the the trace table about it, but then the trace would tell who deleted it

so all the info needed is available without asking on a forum.
in any case speak to Your support
cheers

Thanks for the response enrico!
I have contacted the support. they said program failed due to queue id error and they asked me to analyze the code how TS queue deleted. I am not sure how to proceed with anlysis, thats why posted the question here.
Thanks,

1. Find the source code.
2. Look for EXEC CICS DELETEQ TS statements.
3. Look at the logic before each statement to determine under which condition(s) the statement is executed.

Applications may delete the TS queue to ensure that starting a new transaction does not involve any data from an old transaction. The application may have been coded to delete the TS queue for any number of reasons, actually, so you need to start reviewing code, paying attention to the comments in the code.
