[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - datasource pool is alocated twice
Hi,
I'm using jboss 4.0.5. I have XA datasource with oracle 10 as database. I init my
application using a start up servlet. In the init method of the servlet I do some queries
to database which are done ok. Then in the first time that I try to get a database
connection using stateless ejb I see that the jboss is allocate the pool again.
So even that my data source is defined in oracle-xa-ds.xml
<min-pool-size>10</min-pool-size>
<max-pool-size>40</max-pool-size>
I can see in the JCA jmx JBossManagedConnectionPool that
AvailableConnectionCount - 80
ConnectionCount - 20
MinSize - 10
MaxSize - 40
Before getting the connection from ejb
AvailableConnectionCount 40
ConnectionCount is 10.
MinSize - 10
MaxSize - 40
I always get the connection in the same way
(DataSource) ic.lookup("java:/DataSourceDS").getConnection();
The different is the context that I come from, servlet or ejb.
Any idea?
My full data source definition is:
<xa-datasource>
<jndi-name>DataSourceDS</jndi-name>
<track-connection-by-tx/>
<isSameRM-override-value>false</isSameRM-override-value>
<xa-datasource-class>oracle.jdbc.xa.client.OracleXADataSource</xa-datasource-class>
