how to configure max pool size for hornetq resource adapter

[mandarbk]

How can I specify min-pool-size and max-pool-size for hornetq resource adapter in JBoss 7 ?

I can see a 'resoruce-adapter' element in the schema, but looks like it is used only for custom resource adapaters.Since hornetq is integrated as a default JMS provider in JBoss 7, I can not specify the 'archive' element for resource-adapater schema and the archive configuration is madatory.

At times, I get an exception in the log something like... "Unable to get managed connection within a maximum specified time period". My application is using JMS quite extensively, so I presume that this could be an issue with connection pool getting exhausted. I am still investigating the connection leakage.

Did not get much of a help from HornetQ user group.Hence posting here.

Does MDB maxSession limit of 20? have the answer you're looking for?

[mandarbk]

No.It is not just about MDBs.

Imagine a plain java class calling connectionFacory.getConnection(), where the connectionFactory is JMS connection factory("java:/jmsXA").

Let's say multiple session beans are using this class for publishing messages to a queue/topic.Under high load conditions, assume that say 100 session bean instances are concurrently attempting to get the connection from JMS connection factory.

If the default limit is set to say 50, the remaining session beans are bound to get an exception... something like ... Unable to get Managed connection within a specified timeout period of XXXXms.

I am loooking for a configuration where I can alter the value of maximum connections that can be retrieved from the connectionfactory.Based on optimum load conditions, I can decide the value suitable for my environment.

I see. IronJacamar is the JCA implementation which would be managing this. Have you had a look over there?

[mandarbk]

I would have expected the configuration to be part of the standalone.xml.I did browse through all the schemas, but could not find it.

I will take a look at Ironjacamar and check out if I can find the solution.

Thanks Stephen.

The HornetQ resource adapter is embedded inside the application server and hence the configuration is done through the messaging subsystem.

Any parameters should be in the XSD, if not the HornetQ team should be able to help you.

I have double-checked the messaging XSDs. Did not find anything for configuring max-pool-size ?

I would have expected 'pooled-connection-factory' schema to have a provision for managing pool size.

I had already posted the same issue in HornetQ user group. The response I received indicates that hornetq guys expects pool configuration to be AS side isssue.https://community.jboss.org/thread/177917

In the other thread you mention about a exception. Can you post that entire exception stacktrace?
