Process states requiring a reboot
Does anyone knows why VMS can not kill the process when doing stop/id ? I know that you can write a program to do the job but I don't want to do this. In my opnion, a good OS should always be able to kill the process.

You should monitor the quotas with Amds or Pquota
http://h71000.www7.hp.com/freeware/freeware40/pquota/
I know several sites runnng Sybase with no problem with Vms V 7.3
Of course, they have put correct quotas.
Rwast stands for Resource Wait Asynchronous System Trap
The doc says
Indicates that the process is waiting for a resource whose availability will be signaled by delivery of an asynchronous system trap (AST).
In most instances, either an I/O operation is outstanding (incomplete), or a process quota has been exhausted.

Re: Process states requiring a reboot
We also run without problems if nothing special happens. The quotas of Sybase servers are however NOT working as documented. E.g. try to configure a server with 500 users with quotas as documented. Then try to open 500 connections. It will not work. You will encounter the bytlm limit.
But the real problem is that VMS doesn't process the stop/id correctly. And yes, I know many tools exists to correct the quota but nothing garantuees that the software will react error free on dynamic changes.
In my opnion VMS should be changed. Stop/id should ALWAYS work.

Re: Process states requiring a reboot
part of your problem probably is the same as what we experienced, being, VMS 7.2.x & 7.3.x needing much bigger quota than 7.1.x and earlier.
Another, much more painfull part, is the memory leak in Sybase (well, at least in the OmniConnect module). We found that by bumping the bytlm quite a lot, we could postpone the RWAST for some weeks, but you WILL run into it. Our current "solution" is to have our nightly backup procedure kill & restart OmniConnect.
If you REALLY need to kill the process, and cannot implement AMDS or Availability Manager, it CAN be done with Delta, but you are guaranteed NO support, and the risk of typo's is entirely yours!! Back in my old ICL (pre-U*X) days, a similar program was more justly called "DYNAMITE", and the commands for it were called "MATCHES".
I have the instructions only on paper, and it is just too much (and error-prone) to retype, but if you REALLY want to have it (AND USE AT YOUR OWN RISK!), than send me an e-mail with your fax number.

Re: Process states requiring a reboot
old question, process RWAST are not killable. HP (formerly DEC) explain in follow page of user guide:

I am a bit surprised, as I think Sybase is not supported on current Vms versions.
I would be much surprised if your doc states Vms V7.3
I think your doc is fine for Vms 6.2 or 7.0

Re: Process states requiring a reboot
Good pointer.
But Sybase doesn't document the quotas anymore. So, how do you calculate them correctly ? Testing is all you can do.
