login process stalls


login process stalls

we have one VAX OpenVMS V6.2-1H3 it was working till Friday today when I tried to log in to the system for a daily checkup my log-in process do not proceeds,it do tells me about my last successful log -in information here is the message

Username: trimuse
Welcome to OpenVMS Alpha Operating System, Version V6.2-1H3 on node vaxapp
Last interactive login on Friday, 6-FEB-2009 14:46:50.95

it is waiting here forever,then I checked with different users, everyone is facing same issue even the system user could not check in.

I checked with my colleges what relevant changes were made, one of my co-worker enabled the auditing for everything
$ set audit /enable=all
we were suspecting that can be the reason as it was working fine before enabling audit for everything.
we have a way to execute commands from one of the other node which communicate with "vaxapp" via decnet, so we stop the audit server
$ set audit /server=stop
then tried log in, this did not help
so we revert and started the audit server again $ set audit /server=start.

we are still in the same hanger

Re: login process stalls


SET AUDIT/ENABLE=ALL can produce a very large amount of data.

My first guess is that the system disk is full. If you have some access to the machine, then freeing some disk space may very well resolve the problem.

Of course, deleting the voluminous audit information is a possibility, but I would recommend moving it to another disk rather than deleting it. It can be deleted later if it is truly not needed.

Re: login process stalls

What is the STATE of the waiting processes, as seen from a logged in process? SUSPEND?

The AUDIT_SERVER is infamous for suspending processes. For example, check out $HELP SET AUDIT/BACKLOG

Are you per chance running out of disk space for the volume with the audit log (sys$sysdevice?)

This me a good time to check with the HP Availability Manager, if you have the collector going for this older OpenVMS version.

Re: login process stalls

If you login /NOCOMMAND then does that help?

Is there some processing in SYLOGIN that is causing a problem?
Perhaps you can edit the SYLOGIN to simplify it and see if this helps?

Check the status of the disks especially the system disk and the disk on which the audit log is place (if different).
Purely Personal Opinion

Re: login process stalls

Do you have something in the sylogin.com file that is doing logging or lookup or so ?

If the file it uses is locked it may wait for ever.

Is batch still working ?

Re: login process stalls

At this point I suspect a bad lock on RIGHTSLIST or such common file.

Is this a cluster?

Not much... It looks like it still hangs, but that was not explicit in the reply.

The last_login time (SYSUAF.DAT) has not been updated.
This suggest to me that the login has gotten 'nowhere'.

The /NOCOM is a handy tool, when a user LOGIN.COM is mucked up, but you indicaed multiple users had the problem.
/NOCOM does not bypass SYLOGIN.COM, but I suspect you do not get that for.

You may want to edit SYLOGIN.COM to leave some breadcrumbs while debugging this, may write a record to a (shared?) file indicating 'entered SYLOGIN for as
