Re: Help with v6 services

T.Rob,

This came up recently via service as well. Here is the solution provided 
to another customer.
<><> 
The setup applies 
equally to a SERVTYPE of SERVER. 
. 
The way that strings can be defined to runmqsc does not allow the full 
range of arguments to be passed to runmqdlq, e.g. the blank strings 
used to define the qmgr's DLQ, or the default qmgr. Also, the service 
manager process cannot call runmqdlq and redirect stdin for the app to 
take its input from a file. For these reasons, I recommend that the 
runmqdlq service is started by defining a script in STARTCMD, and for 
that script to call runmqdlq with the required arguments. 
. 
For example: 
. 
I want to use the qmgr's defined DLQ, and to load the rules from a 
file. I define the service like this: 
. 
DEFINE SERVICE(DLQH) + CONTROL(QMGR) + DESCR('DLQ Handler Service') + 
SERVTYPE(COMMAND) + STARTCMD('/opt/mqm/bin/go.dlq') + 
STDOUT('/var/mqm/errors/dlq.out') + 
STDERR('/var/mqm/errors/dlq.err') REPLACE 
. 
The file /opt/mqm/bin/go.dlq looks like this: 
. 
#! /bin/ksh 
runmqdlq ' ' NG2 < opt/mqm/bin/dlq.rules 
. 
and opt/mqm/bin/dlq.rules: 
. 
WAIT(YES) 
REASON(*) ACTION(FWD) FWDQ(FWDQ) 
------------------------------------------------------------------------
SERVICE(SYSTEM.DEAD.LETTER.HANDLER) 
CONTROL(QMGR) 
SERVTYPE(COMMAND) 
STARTCMD(/u/mqm/strdlqH.sh) 
STARTARG(QM_ECLIPSE.DEAD.QUEUE QM_ECLIPSE) 
STOPCMD( ) 
STOPARG( ) 
STDOUT(/var/mqm/errors/QM_ECLIPSE_dlq.out) 
STDERR(/var/mqm/errors/QM_ECLIPSE_dlq.err) 
DESCR(System DLQ Handler) 
My script is: 
#! /bin/ksh 
/opt/mqm/bin/runmqdlq £1 £2 </u/mqm/files/ctp.dlq.prm

Help with v6 services

I am having some difficulty defining a service for the DLQ handler.  When 
I run this service:

DEFINE SERVICE(RUNMQDLQ) +
CONTROL(QMGR) +
SERVTYPE(SERVER) +
STARTCMD('/usr/bin/runmqdlq') +
STARTARG('+QMNAME+.DEAD.QUEUE +QMNAME+ </var/mqm/rulestable') +
STDOUT('/var/mqm/runmqdlq.log') +
STDERR('/var/mqm/runmqdlq.log') +
STOPARG('kill -9 +MQ_SERVER_PID+') +
REPLACE

I get this error:

2006-11-21   10.04.02 AMQ8708: Dead-letter queue handler started to 
process INPUTQ(VENUS.DEAD.QUEUE).

syntax error on line 1
...2006-11-21   10.06.39 AMQ8758: 1 errors detected in input to
runmqdlq.
2006-11-21   10.06.39 AMQ8709: Dead-letter queue handler ending.

Yet when I copy the paramters out of the service definition and run them 
from the command line, everything works fine:

nohup /usr/bin/runmqdlq VENUS.DEAD.QUEUE VENUS </var/mqm/rulestable 
>/var/mqm/runmqdlq.log 2>&1 &

2006-11-21   10.04.02 AMQ8708: Dead-letter queue handler started to 
process INPUTQ(VENUS.DEAD.QUEUE).
<no additional input as DLQ is waiting on messages to arrive>

Any ideas why this is not working?  Anyone have a known working service 
definition for runmqdlq I can look at?

Thanks -- T.Rob
