Anybody have any idea of what this is please? I can't find it in the tools/samples directory and google returns no specific search on it.

Background: I had a RCVR channel apparently stop/start itself, and this was in the Program(amqrmssa.c) attribute of the log print.

A bit of a head-scratcher for me so any pointers gratefully received.

Hmm,

- Google finds nothing

- Knowledge Center finds nothing

- "find" on Linux and AIX find nothing

- "Search" in Windows Explorer finds nothing

If it's not a typo I would say, this is some kind of self-written programm, not a part of MQ

hi...i think it is one of the C libraries used by the amqrmppa.exe (channel pooling process)...

...try checking whether MQ log shows the similar process

I have been seeing the following behavior on one of my 9.1.0.1 MQ queue managers running on RHEL7.

Around once a week, I will get a report that channel was stopped by a user. I feel very confident no user actually did this:

Code:

09/12/2019 01:50:28 AM - Process(18763.3910) User(mqm) Program(amqrmppa)
Host(OBFUSCATE) Installation(Installation1)
VRMF(9.1.0.1) QMgr(OBFUSCATE)
Time(2019-09-12T06:50:28.157Z)
CommentInsert1(CLUSTER.OBFUSCATE)

AMQ9528W: User requested channel 'CLUSTER.OBFUSCATE' to be stopped.

EXPLANATION:
The channel is stopping because of a request by the user.
ACTION:
None.
----- amqrmssa.c : 3331 -------------------------------------------------------

It is usually accompanied with an FDC that looks like this:

Code:

Are you seeing something similar for a similar version of MQ?

Pretty much, yes, but with amqrmssa.c printed in the log and no FDC cut; I think it may be PMR time.

abhi_thri, thank you, I did search the fora to see if there was anything similar, and all came up as the channel-pooling process, which is not the case for me.

That's a definite no, there's no way way I'd allow any libraries to be prefixed amq!

Please show the log print in question.

I would expect to see amqrmssa.c in the dotted line at the end of an error message in the error log along with the line number. This is to help IBM service when they are looking at the code of the product.

I would only expect to see an executable name in the Program attribute. Clearly anything.c is not an executable name and so it would be strange to see it there.

Cheers,
Morag

OK, muy bad. It is indeed the amqrmppa process.

My original post was off the back of information given me, as I did not have physical sight of the logs. Unfortunately that information was erroneous and not the fault of the individual concerned as their MQ knowledge is limited (organisational problem, not the individual's) - they were looking at the wrong line of the log print.

I have suggested opening a PMR to get an explanation for this activity.

Many thanks for all the responses, and my apologies if I wasted your time.

I raised a PMR about it, as well.
