Single-threaded queues and UBEs calling other UBEs...

We have a custom UBE that calls another custom UBE. The UBE being called needs to
run in a single-threaded queue to ensure that only one copy runs at a time.
We have the version set for a single-threaded queue, but when it's called by
the other UBE, it runs in the queue that UBE ran in instead. Since the calling UBE doesn't finish
until the called UBE finishes, we can't just set the calling UBE to run in the single-threaded queue.
Has anyone had this problem before, and if so, how did you solve it?

It is called queue inheritence. I believe that in SP23 PSFT introduced an INI file option to disable it.

Can you use an async UBE call? In other words, do you need the caller to wait until the called UBE completes? If not then use async and run in a single threaded queue. It will just queue up the called UBE at the end of the queue so it will start up some time after the calling UBE ends.


Hope that helps,
