[JBoss-user] [Messaging, JMS & JBossMQ] - JDBC2 Persistent Manager in XA Environment
Hi, My application updates multiple message queues (provided by jbossmq) and databases in one transaction through session beans with CMT. I am using jdbc2 persistent manager which uses a LocalTX only for its datasource. Since my app is running in an XA environment , will this cause any problem ? Or should I configure jdbc2 persistent manager to use XADatasources ? Does it work too if I configure with NoTx Datasources? Thanks in advance.

[JBoss-user] [JCA/JBoss] - Getting Unrecognized transaction..
Hi,
I have a application deployed under these configurations:
-OS=Gentoo Linux Kernel 2.4.25
-JVM=Blackdown1.4.1
-JBoss-3.2.3
-RDBMS=Firebird-1.5.0 (Classic Server)
-JDBC=FirebirdSQL-1.5.0-RC2 (deployed as a JCA adapter. Pooling is set to discard idle
connections after 15 minutes)
Sometimes I would get this kind of exception while closing a Jdbc connection:

It's kind of difficult to reproduce this problem.
But everytime this exception occurs, 1 additional physical connection doesn't get
discarded, even after overnight (when no one is even using the application). I can see
this by running pstree on the linux console. (One managedConnection is associated with
one process).
Then I decide to download the jboss-3.2.3 source code, open TxConnectionManager.java
and observe line 554 where the connectionClosed method calls delist()
| if (isManagedConnectionFree())
| {
|//log.trace("called unregisterAssociation, delisting");
|//no more handles
|delist();
|//log.trace("called unregisterAssociation, returning");
|returnManagedConnection(this, false);
| }
| //log.trace("called unregisterAssociation");
| }
| catch (ResourceException re)
| {
| log.error("ResourceException while closing connection handle!", re);
| } // end of try-catch
|
Now my question:
If an exception occured (like the one i have) while delist() is called, then the
returnManagedConnection(this,false) won't be called. Does this mean that the
managedConnection will never be returned to the pool thus causing some sort of a leak
?
If so would it be safe to do this:
| if (isManagedConnectionFree())
| {
|//log.trace("called unregisterAssociation, delisting");
|//no more handles
|try{
|delist();
| }catch(ResourceException re){
|//log.trace("called unregisterAssociation, return and KILL");
| returnManagedConnection(this, true);
|//rethrow
| throw re;
| }
| //log.trace("called unregisterAssociation, return ");
| returnManagedConnection(this,false);
| }
| //log.trace("called unregisterAssociation");
| }
| catch (ResourceException re)
| {
| log.error("ResourceException while closing connection handle!", re);
| } // end of try-catch
|
|
Thanks for any comments and answers.
