JMS Adapter - Messages in Delivering Mode in AE

[Former Member]

Hi PI Experts,

We are getting a continuous issue with Messages getting stuck in Adapter Engine Queues in Delivering Mode. We are using Receiver JMS Adapter at target. As and when we restart Java Stack of PI , messages get delivered successfully.

And again new message get stuck with Delivering Mode. Please suggest the cause for it and solution to the problem.

Looking for prompt answers.

Thanks & Regards,

Anurag,

You can change few parameters in NWA in order to prevent this from happening again.

Max concurrency - change to 10

"messaging.system.queueParallelism.maxReceivers" - change to 2.

MaxThreadCount = 350

1. Do a complete CPA cache refresh and check if this solves the issue (it did for us once)

2. Check if all the queues are active and registered

3. Is you message process EOIO? Then check if there is any particular message that causes the issue

Hi Shabrish,

As per the details from MQ Server technical guys, thread is opened by admin user of PI to put the messages on queues of MQ server and that thread does not get close itself and keep on hanging the message in Delivering Mode. Because of this issue all messages behind it get queued to Delivering mode .And as soon as we restart the Java Stack it gets flushed up and open the new connection and deliver all old messages but new message again get stuck in Delivering Mode.

Any idea on this.

Hi Anurag,

You might need to update the MQ client jar files in jmsproviderlib.
