We have an application which is connected to MQ Queue manager using SVRCONN channel and I noticed that there has been no transactions happened in the last 24 hours but the LAST MSG TIME on the SVRCONN channel instances keep updated every 1 second.
What could be the reason of this?
MQ version we are using is 8.0.0.10 on LINUX. |

Heartbeats won't drive the LAST MSG TIME, but MQ API calls will.
The term "MSG" is misleading, everyone not surprisingly assumes it means application messages. Why IBM chose to use that term to also cover MQ API calls is one of the mysteries of MQ.

The app is not well written and keeps issuing MQ API calls over that channel every second.

Thanks. I stand corrected. (I should not post while taking codeine cough syrup.)
An MQGET with a one second WAITINTERVAL would qualify as not well-written.

Hi, it seems you are right that is probably the reason, I myself couldnt think of any other reason. |

Hi Bruce, channel substate is showing as "RECEIVING', so I dont think it is MQGET call, in that case the substate will change to "MQWAIT". |
