If you change your service definition back to the way it was originally where runmqdlq was called directly without a script, has the stderr messages that your reported originally went away?

Code this in the DLQ rules

Code:

WAIT(YES)

I have a WAIT in the rules, this is the default if not specified though so should not make any difference

Your STARTCMD in your service can not be:

/var/mqm/qmgrs/IB9QMGR/dlqhandler.sh

That is not an executable. It is an ASCII file. It should be something like:

ksh /var/mqm/qmgrs/IB9QMGR/dlqhandler.sh

But still, I would recommend changing it back to the way you had it. No need to invoke a script here.

I'm interested to know why you are suggesting not to use a script when other references are suggesting it should run as a script.
I will try reverting it back to executing runmqdlq

Thanks

I will post my working config here

Quote:

DEFINE SERVICE('XXX.DLQHANDLER') CONTROL(STARTONLY) SERVTYPE(SERVER) +
DESCR('Dead Letter Queue Handler') +
STARTCMD('+MQ_DATA_PATH+DLQ_start') +
STARTARG('+QMNAME+.DEAD.LETTER.QUEUE +QMNAME+ +MQ_DATA_PATH+DLQ_rules.txt') +
STDERR('+MQ_DATA_PATH+DLQ_stderr.txt') +
STDOUT('+MQ_DATA_PATH+DLQ_stdout.txt') +
REPLACE

START SERVICE('XXX.DLQHANDLER')

Quote:

#!/bin/ksh
echo $1 $2 $3

echo Started `date '+%Y%m%d %H%M%S'`

runmqdlq $1 $2 < $3 > /dev/null 2>&1

This is working fine for Zpat now...

For the time being and until you have it working, don't redirect the output to /dev/null. Rather set it to a writable file that you can then look at and determine why what you see is happening...

This config works in the same way, ie from the console but not as a service.

What version of MQ are you running this on?

I've used this on AIX with both MQ 7.0.1.x and 7.5.0.3.

Thanks .. I need to raise a PMR as I think this is an issue with 7.5.0.1 on Linux 64 bit

I would start by applying FP 7.5.0.3

Sorry, I was incorrect about my statement on needing the ksh before the script on the STARTCMD. I was making the assumption that an execve system call (which is probably what MQ is doing under the covers to start your command) needed to be a binary executable. But I looked up the execve, and a script is supported, as well. So ignore that post. It is incorrect.

Quote:

execve() executes the program pointed to by filename. filename must be either a binary executable, or a script starting with a line of the form:

#! interpreter [optional-arg]

One last note. If your 500 (cevans) user id did not have access to open your input file to runmqdlq, I would recommend you try the service the original way you had it to see if your issue is fixed, now that your queue manager has been started under the mqm id. It at least wouldn't hurt to try this, to rule out that your current issue is more with getting your script to run correctly as a service.
