Hi Guys,

I am using MQJMS API to connect to MQ server and using same for XA connections as well.

Using MQXAConnectionFactory for same.

All things are working fine.
But, under stress load of 200 user with 10 MB payload. MQ JMS API is throwing XAException with error code '106'

From the IBM doc
:https://www.ibm.com/support/knowledgecenter/en/ssw_ibm_i_73/apis/dxatlend.htm

106 [XA_RBTIMEOUT]

It means : A timeout occurred in the resource manager.


Now, how can I increase the timeout of this? and does any knows what is the default timeout for resource manager?

How to avoid this XAException?
I searched on IBM docs but couldnt find anythng,

Please suggest.

Any help will be appreciated.

Many Thanks!

Do you have enough connections defined in the pool?

One of the reasons to get a timeout under load is to have to wait for a connection availability. If the pool is fully utilized, this may happen.

Also the 10MB payload makes me think you need to use a CCDTURL in order to set the max message length on the client channel. 10 MB is more than twice the default of 4 MB.

On top of that make sure the sharing of sockets is minimized. 10 MB takes some time to traverse the socket and you don't want to spend this time waiting...

Have fun
