TIBCO BW 'Get JMS Queue Message' activity with IBM MQ does not perform well

[Raj Aryan 2]

I'm working on a POC where we are trying to connect toMQ Queue manager over JMS binding files. we are sending MQ messages using TIBCO "JMS Sender" activity and getting the reply messages on same MQ reply Queue(Multi engine environment) using TIBCO "get JMS queue message" activity with selector condition as correlation id=msgid.

 

the issue which we see is Get JMS queue activity is failing and waiting for longer time(12 sec) than timeout(2 sec) which is given in its config and another pattern we see with stalled transactions is sequencing of failure transaction in given BW process instance

lets say first transactiontook 12 sec , then 2nd transaction is taking 11 sec and next transaction's response times are descending order.

Config:

ThreadCount:32; Maxjobs:30;FlowLimit:60:TPS:50-60 TPS; No of instance:8; MaxHeapsize:2048MB;MinHeapSize:256MB

Note: it's happening to all the BW instances frequently and MQ vendor responding within 2 sec for all the failed transactions.

we know that TIBCO JMS MQ bindingwill make connection for each transaction and we believe above scenario is happening due to it so we tried using TIBCO MQ Plugin but it didnt improve performance.

is there any solution to this issue which we can resolve using Get JMS Queue Message itself.

Does anyone know of a solution to this issue. We are also experiencing a similar problem on the Jms connector and the MQ Plugin has not improved the experience.
