[jboss-user] [JBoss Messaging] - Max. Pool size for JmsXA

Hi, We are running our application with JBoss 4.2.3 GA with JBM 1.4.0SP3. I have just changed my anti pattern ,connection creation code to JmsXA lookup. I could see a great performance improvment. With default setting i am getting below error. I guess it has something do with default max pool size, which is 20. in hajndi-jms-ds.xml i.e. <max-pool-size>20</max-pool-size> | Could not create a session: javax.resource.ResourceException: No ManagedConnections available within configured blocking timeout ( 30000 [ms] ) | javax.jms.JMSException: Could not create a session: javax.resource.ResourceException: No ManagedConnections available within configured blocking timeout ( 30000 [ms] ) | at org.jboss.resource.adapter.jms.JmsSessionFactoryImpl.allocateConnection(JmsSessionFactoryImpl.java:421) | at org.jboss.resource.adapter.jms.JmsSessionFactoryImpl.createQueueSession(JmsSessionFactoryImpl.java:145) | at com.alservices.imaging.export.process.util.AuditUtil.setjobDocResource(AuditUtil.java:281) | I have increased it max-pool-size and i could reduce frequency of above error. Our application does a heavy usage of messaging. I have two basic question 1) Above error is because of low pool size ? if Yes , what is the max. limit for max.pool.size 2) If above error is not because of pool size , what could be other reason ? Thanks in advance. Hoping for right direction. Rana View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4201429#...
