Hi,
I have a client application putting message in the remote queue, there is no issues with the QueueManager but in between...there are error seen in the logs of the clent application saying that
Unable to MQ commit (CompCode=2, Reason=2018)
this error is seen rarely but its re-occuring.
As far as my knowledege as I went through IBM site to see the reason it says that there is some MQCONN network issue not exactly a MQ error, but I want to know what can be done to fix this issue.
I have HP_UX 11.1 OS and MQ 5.3.
Can someone help on this it will be of great
Thanks

According to the IBM site:
| Quote: |
MQRC_HCONN_ERROR
Explanation:
The connection handle Hconn is not valid, for one of the following reasons:
- The parameter pointer is not valid, or (for the MQCONN or MQCONNX call) points to read-only storage. (It is not always possible to detect parameter pointers that are not valid; if not detected, unpredictable results occur.)
- The value specified was not returned by a preceding MQCONN or MQCONNX call.
- The value specified has been made invalid by a preceding MQDISC call.
- The handle is a shared handle that has been made invalid by another thread issuing the MQDISC call.
- The handle is a shared handle that is being used on the MQBEGIN call (only nonshared handles are valid on MQBEGIN).
- The handle is a nonshared handle that is being used a thread that did not create the handle.
- The call was issued in the MTS environment in a situation where the handle is not valid (for example, passing the handle between processes or packages; note that passing the handle between library packages is supported).
Completion Code:
MQCC_FAILED
Programmer Response:
Ensure that a successful MQCONN or MQCONNX call is performed for the queue manager, and that an MQDISC call has not already been performed for it. Ensure that the handle is being used within its valid scope (see the description of MQCONN in the WebSphere MQ Application Programming Guide).
|
So not so much a network issue as a programming bug, where the handle being used for the commit has gone out of scope or otherwise been rendered useless as indicated above.

Don't think I can put it better than that.
