Hello!
I'm using a postgreSQL v8.0 running in an other server.
I'v set a value of 10 as a min pool in my postgre-ds.xml.
Then, running ManageEngine Application Manager 7.
AppManager show 0 pooled connection for my database but 5 for DefaultDS : Hypersonic Database.
Here's a portion of postgre-ds.xml
<min-pool-size>5</min-pool-size>
<max-pool-size>150</max-pool-size>
<idle-timeout-minutes>20</idle-timeout-minutes>
<!-- sql to call when connection is created-->
<new-connection-sql>SELECT 1</new-connection-sql>
<!-- sql to call on an existing pooled connection when it is obtained from pool
-->
<check-valid-connection-sql>SELECT 1</check-valid-connection-sql>
<!-- corresponding type-mapping in the standardjbosscmp-jdbc.xml (optional) -->
<metadata>
My question is : Do JBoss creating the minimal pool when starting JBoss?
Or maybe I'v a wrong setting in my XML?
The problem : a first launch of my CMP Bean always fail. Throwing the next error:
09:06:37,687 WARN [TransactionImpl] XAException: tx=TransactionImpl:XidImpl[FormatId=257, GlobalId=Herimiaina/67, BranchQual=, localId=67] errorCode=XA_UNKNOWN(0)
org.jboss.resource.connectionmanager.JBossLocalXAException: Error trying to start local tx: ; - nested throwable: (org.jboss.resource.JBossResourceException: SQLException; - nested throwable: (java.sql.SQLException: ERROR: SET AUTOCOMMIT TO OFF is no longer supported
))
at org.jboss.resource.connectionmanager.TxConnectionManager$LocalXAResource.start(TxConnectionManager.java:901)
at org.jboss.tm.TransactionImpl$Resource.startResource(TransactionImpl.java:2043)
at org.jboss.tm.TransactionImpl.enlistResource(TransactionImpl.java:563)
But reruning the bean immediatly success.
I'v trying it using BMP now. When getting the connection in setContext()
, I got the same problem. To solve it, I loop my code 4 time until I get a valid connection. And this work but add a heavy load to JBoss.
