Reply with quote

Hi,

We have made a few updates to our COBOL code to internally restart our program retry the IDMS command when there is an IDMS deadlock eg. Error code - 1229. But usually this kind of scenarios occur only in production and does not normally comes up in test environment. Is there any way I can recreate this scenario in test environment ? I mean to get an explicit lock on the record (using dmlo or something) so that when program executes the statement will encounter the deadlock.
Thanks

Hello,

To force a deadlock use 2 tasks that need the same 2 rows. Read anywhere about "deadlock" or "fatal embrace".

Then implement code that will force the condition.

This will work with every database engine i've used.
