    Jboss JMS error - help needed

    Ravikiran Chittari Newbie

      I am getting the following error in my server logs.

      Does this mean (a) My defaultDS connection that points to hsqldb is max-ed out on connection pool? Hsqldb is used for jms messages.

      OR it is jms-ds.xml that manages jmsXA ds?


      ERROR [org.jboss.resource.adapter.jms.JmsSessionFactoryImpl] could not create session

      Thanks for your help..

          can you post some configurations - i mean what is the hsql-db.xml looking like ?

            The standard stuff that comes with jboss isntall. Below are two relevant params for hsqldb-ds.xml

            <!-- The minimum connections in a pool/sub-pool. Pools are lazily constructed on first use -->
            <min-pool-size>5</min-pool-size>

            <!-- The maximum connections in a pool/sub-pool -->
            <max-pool-size>20</max-pool-size>


            For jms-ds.xml, again standard stuff
            <tx-connection-factory>
            <jndi-name>JmsXA</jndi-name>
            <xa-transaction/>
            <rar-name>jms-ra.rar</rar-name>
            <connection-definition>org.jboss.resource.adapter.jms.JmsConnectionFactory</connection-definition>
            <config-property name="SessionDefaultType" type="java.lang.String">javax.jms.Topic</config-property>
            <config-property name="JmsProviderAdapterJNDI" type="java.lang.String">java:/DefaultJMSProvider</config-property>
            <max-pool-size>20</max-pool-size>
            <security-domain-and-application>JmsXARealm</security-domain-and-application>
            </tx-connection-factory>


            My suspicion is that the max pool size in tx-connection-factory defined in jms-ds.xml is low for the txns I am handling. Hence getting this error.
            But, want to see if anyone else has run into this issue.

            Would be nice if Jboss wiki has some good pointers to this topic.

              <max-pool-size>20</max-pool-size>


              It is defaults values, You should to suit its to own needs / average load.

              And try check in JMX listConnectionInUse() in CachedConnectionManager or something similiar. Mayby you are not release some connections.
