%SHOW-W-NODE_ERROR

Can anyone shed any light on this error message??

$ Show User/Full
%SHOW-W-NODE_ERROR, unable to display information from node BUD
-SYSTEM-F-BADPARAM, bad parameter value

The command is being run, in batch and on Node BUD, in a nightly script which has not been modified in almost a year. This error has not been seen before.

$ help /message SHOW-W-NODE_ERROR
%MSGHLP-F-NOTFOUND, message not found in Help Message database

Has anyone seen this before??

Re: %SHOW-W-NODE_ERROR

Are we dealing with a cluster and trying to show nodes from node to another ?
SMISERVER running ?

Re: %SHOW-W-NODE_ERROR

We are running in a cluster (3 Nodes, BUD, CITIUS & SPEEDY), however the command is being executed on Node BUD, and the error is "... unable to display information from node BUD".

Interestingly, it immediately follows up by displaying the information it claims to be unable to display.

I suspect that the command (unluckily) collided with some other process trying to access the Process Table.

Re: %SHOW-W-NODE_ERROR

Dave,

I've found a mention of a %SHOW-W-NODE_ERROR in c.o.v. from 11-JAN-1991 ;-) But I don't remember ever seeing this myself.

[CLIUTL]SHOWUSER reports this error in routine jpidone_ast, if the IOSB contains an unexpected status.

$GETJPI works with the CLUSTER_SERVER process on the remote nodes, not with SMISERVER. So check that process on node BUD. Or maybe there are some processes on node BUD in a questionable state ?

And maybe try some F$GETJPI calls yourself to node BUD to determine, what the problem may be.

Re: %SHOW-W-NODE_ERROR

Dave,

SHOW USER/FULL did display some users from node BUD and just reported ONE error.

It's calling $GETJPI with a completion AST and continues with the next $GETJPI call (from the AST) until receiving ss$_nomoreproc. It would signal a SHOW-W-NODE_ERROR for any unexpected error in this loop.

So there seems to be exaclty ONE process on BUD, which causes $GETJPI to fail with SYSTEM-F-BADPARAM, you just need to find that process ;-)

I don't expect there to be any issues walking the process list.

Re: %SHOW-W-NODE_ERROR

Dave,

%SYSTEM-F-BADPARAMS could be returned by $GETJPI, if the item list contains a bad identifier. The item list for each call is built in P0 memory of SHOW.EXE - it might be hard to further diagnose this...

Re: %SHOW-W-NODE_ERROR

Thanks for the very useful information Volker, you sent me in the right direction I think.

Looking at the system process list I found;

OpenVMS V8.3-1H1 on node BUD 12-FEB-2010 08:39:42.28 Uptime 61 06:36:38
Pid Process Name State Pri I/O CPU Page flts Pages
2020042D PMDF counters MUTEX 6 1259748 0 00:02:07.23 6122 5655 M

I notice that this process is in Mutex state on all of my cluster nodes and standalone nodes (that are running PMDF).

I will be forwarding this issue to Process Software.

thanks for your help.

Re: %SHOW-W-NODE_ERROR

I think the above is the source of the problem so I will forward it to Process Software for investigation.

Re: %SHOW-W-NODE_ERROR

Dave,

you can do the first analysis steps yourself:

See
http://h71000.www7.hp.com/wizard/wiz_2347.html

$ ANAL/SYS
SDA> SET PROC "PMDF counters"
SDA> SHOW PROC
... look for Event Flag Wait mask
SDA> READ SYSDEF
SDA> FORMAT JIB
SDA> EXIT

This information should get you started diagnosing the MUTEX wait state.
