This says you are exceeding the default connection pool size of 20. Add a max-pool-size element:
<max-pool-size>NNNN</max-pool-size>

Hi Guys,
In order to test the concurrency in my system, I created a Threaded standalone application and tried to invoke a Stateless Session Bean concurrently 100 times.
What the Session Bean does is fairly simple, It calls an entiry bean which in turn searches for the primary key in the database. If there is'nt one, it creates a new record.
When I executed my threaded applicatoin, I got the following Exception stack trace. Can somebody explain be about this 'No ManagedConnections Available!'. Am I missing something in the way I have configured my datasource.
My datasource configuration is : <datasources> <local-tx-datasource> <jndi-name>OracleDS</jndi-name> <connection-url>jdbc:oracle:thin:@193.16.18.142:1521:testdb</connection-url> <driver-class>oracle.jdbc.driver.OracleDriver</driver-class> <user-name>dev</user-name> <password>dev</password> <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleExceptionSorter</exception-sorter-class-name> </local-tx-datasource>
</datasources>
Environment: jboss-3.2.1_tomcat-4.1.24, Oracle 8.1.6, Jdk 1.4.1_01
Thanx in advance, Magesh
