Whats the difference between the below two rules
REASON(MQRC_Q_FULL) ACTION(RETRY) FWDQ(&GAYATHRI.MESSAGE.QUEUE) FWDQM(&GAYATHRI) RETRY(3)
http://publib.boulder.ibm.com/infocenter/wmqv6/v6r0/index.jsp?topic=/com.ibm.mq.csqzal.doc/fg17010_.htm
and
REASON(MQRC_Q_FULL) ACTION(RETRY) RETRY(3)
hope both does the same work,
for the first rule, can specify the Destination queue name and queue manager(if you know it already)
Second rule, it will get the destination queue and destination queue manager from the header. am i correct here.
Which one should good to use, if anything wrong if i use the first one.
Say if there are 100 messages in the dead letter queue
first 50 destined queue is GAYATHRI.MESSAGE.QUEUE and
the second half destined queue is GAYA.QUEUE.
Assume, if i use the first rule, does it route all the messages (100) to GAYATHRI.MESSAGE.QUEUE or just 50.

should the action not be fwd here ?
the difference is that the second rule retries for the original destination queue and frst rule fwds to the specified queues

None - ACTION(RETRY) ignores the FWD parameters. ACTION(FWD) FWDQ(&DESTQ) is the same as ACTION(RETRY) but is less typing.
I've no idea what your point is with the link to the sample programs. You'll find the dead letter handler described here for your convienience.
If you have 2 types of message on the DLQ, to be forwarded to 2 different queue, you need more matching options.

So there is no difference,
ACTION(FWD) FWDQ(&DESTQ) FWDQM(&DESTQM) is it equivalent to ACTION(RETRY)
If you have 2 types of message on the DLQ, to be forwarded to 2 different queue, you need more matching options.
I agree with these.
Say: if i specify ACTION(FWD) FWDQ(&DESTQ) FWDQM(&DESTQM) does it route all message to the destination queue. though there were some different Destination queue. |

Yes there is - you've specified a destination queue in your first example (which would be ignored & is not syntactically correct) which presumably you want to use.

What do you mean by the destination queue? Each message has it's own destination (and in your example there are 2)
Consult the link for more details. Or details.

ACTION (FWD)
ur msgs should be routed to actual destination queue i.e. the queue name from the DestQName field in the MQDLH structure.

yes, i understood.
Thanks for clearing my doubts.
so &DESTQ, &DESTQM all are important if we are using ACTION(FWD)
and as Vitor said, if i am using ACTION(RETRY) will override the usage of
ACTION(FWD) FWDQ(&DESTQ) FWDQM(&DESTQM)

No, what I said was ACTION(RETRY) will ignore FWDQ & FWDQM.
You can't specify 2 actions for a single pattern match. Well you can, but only 1 will work.

ACTION(FWD) FWDQ(&DESTQ) FWDQM(&DESTQM)
and
ACTION(RETRY) RETRY(1)
does the same job for u....

The big difference between
action(retry)
and
action(fwd) fwdq(&destq)
is the non expressed option as in
action(fwd) fwdq(&destq) header(yes|no)
retry implies header(no).
In other words you can forward the message somewhere but keed the DLQ header....
Enjoy
