We had 1 MQWF system set up with 1 queue manager. We started testing batch submissions over the XML interface(CreateandStartProcessInstance), but when a batch job was running, all of the non-batch submissions were timing out. The non-batch job submission were using the java api's.
So we created a second queue manager and a second MQWF system to submit the batches to. The idea is to use 2 systems on the same server, same database and when connections are made the apps will specify the QM instead of the group so WF will not load balance.
So
(1)'normal' submissions go to QM A over the java API's
(2)Batch submission go over the XML interface to QM B.
The problem is that when submitting a batch to queue manager B, the calls to QM A STILL time out. I watched the queue's and the RTSINPUTQ on queue manager A seemed extremely slow to consume messages. The batch itself runs with no problem.
I don't see any errors in the MQ or MQWF logs.
Is this behaviour expected? |

Hi,
this behaviour is very interesting and NOT as expected.
Are your java applications performing well if no batch job is running?
Are you checking XMLINPUTQ of qmgr B vs. RTSINPUTQ of qmgr A?
Which version/service level of MQWF and MQ do you use?
What is your operating system?
I assume you did your tests on a single box. Can you separate your MQWF systems on two different boxes and re-test?
Maybe a concentrator setup could help in your situation(?) |

Hos,
I have a similar problem. I would like to use one QM for online messages from WF Webclient. One QM for expiration of messages ( from workflow itself - I run the scheduling server on this system)
Strangely I find that I cannot login when RTSINPUTQ on QMB is full.

| My problem was fixed by increasing the DB2 buffer size. |
