Pool size is set to 250. And I have been monitoring DS in JMX and always see atleast 150 free connections. It's really random. I have looked at oracle and I see just 250 sessions overall at any given point of time. It's really perplexing.
<local-tx-datasource>
<jndi-name>EDS</jndi-name>
<connection-url>jdbc:oracle:thin:@(description = (address_list = (address = (protocol = tcp)(host = e3.p.i.com)(port = 1526)))(connect_data = (sid = eper3)))</connection-url>
<connection-property name="SetBigStringTryClob">true</connection-property>
<!-- recommended by Oracle support to avoid ORA-01461 errors -->
<connection-property name="oracle.jdbc.RetainV9LongBindBehavior">true</connection-property>
<max-pool-size>250</max-pool-size>
<driver-class>oracle.jdbc.OracleDriver</driver-class>
<!-- Uses the pingDatabase method to check a connection is still valid before handing it out from the pool -->
<valid-connection-checker-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleValidConnectionChecker</valid-connection-checker-class-name>
<!-- Checks the Oracle error codes and messages for fatal errors -->
<exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleExceptionSorter</exception-sorter-class-name>
<!-- sql to call when connection is created
<new-connection-sql>some arbitrary sql</new-connection-sql>
-->
<!-- sql to call on an existing pooled connection when it is obtained from pool - the OracleValidConnectionChecker is prefered
<check-valid-connection-sql>some arbitrary sql</check-valid-connection-sql>
-->
<!-- corresponding type-mapping in the standardjbosscmp-jdbc.xml (optional) -->
<type-mapping>Oracle9i</type-mapping>
<security-domain>EncryptedOracleDbRealm</security-domain>
