MQ - unable to allocate socket msgs

Discussion:

Hello,

We're running MQ for z/OS V7.1 and we ran into a production problem that I'm a bit confused on. Starting this morning for about an hour or so, I'm seeing this message in our CHIN.

CSQX500I <A2 CSQXRCTL Channel PRD02.RACF.CIC9.CHL2 started
CSQX212E <A2 CSQXRCTL Unable to allocate socket,
channel PRD02.RACF.CIC9.CHL2
TRPTYPE=TCP RC=0000045B (EADDRINUSE) reason=744C7247
CSQX599E <A2 CSQXRCTL Channel PRD02.RACF.CIC9.CHL2 ended abnormally

PRD02.RACF.CIC9.CHL2 is a Sender channel that sends messages down to Middleware node AIXPRD02. Here's my confusion - on a Sender channel, is the socket allocated on the Mainframe or would it be allocated on the Middleware node. I'm not sure if this is an issue on my side or the Middleware side.

Can you point me in the right direction......thanks!

It's on the mainframe side. Did you read this?:

Bob - thanks, this helps.

This particular MQ system is one we inherited. The OPORTMIN value is set at 1481 / the OPORTMAX value is set at 1495. Does this tell me I can only have 15 sender channels running ? The Middleware group has added a good amount of clusters, so we have increased over the last year. Yesterday, during this timeframe, they recycled quite a few of their qmanagers and once they were up, channels were starting like crazy. I suspect we hit the port limit and therefore received the socket errors.

I will look into changing the oportmin/oportmax value to 0 - similar to how our other MQ systems are defined.

Yep, you probably ran out of ports.
