Jim,

Just to throw another angle at it. I once had a situation at a client where there was a scripted hacking attempt. (Don't worry, I discussed with the network guy about how they got past the firewall.) By keeping the virtual device list "clean" I was easily able to detect that there were far more than there should have been.

The number of virtual devices can be controlled by a system value as well. I don’t see the value in removing virtual devices in most environments, the exception being where specific authority to devices is set due to security requirements. Then again in those environments we don’t automatically create them either.

Sure I may be deleting someone's current workstation but it will automatically rebuild also. Some of these haven't been used in a long time.

Odd that it would delete the message queue and not the device. I can think of a few oddball scenarios where this would happen.
- QSECOFR not specifically authorized to this workstation. (See QLMTSECOFR)
- Workstation using a different message queue
But instead of guessing I'd look at the joblog.

The object description does have a last used date.

Subject: Deletion of Virtual Display Devices



There is a job on my system that I have inherited that executes at 3:00 AM. The job varies off all virtual display devices (QPAD*) and then deletes them. If they are needed again, the system will recreate them.

Does anyone else utilize this practice and do you see any benefit to purging virtual display devices rather than just allowing them to accumulate?

We have had a couple recent occasions where the device description was not deleted but the associated message queue was.
