JCA ConnectionManager.allocateConnection

[Krankila Norbert Ing.]

Tak hacik bol v tom, ze IBM WebSphere forcuje UnShared Connection, pokial resource adapter nepodporuje ziadnu transakciu. 
Po zmene v ra.xml: <transaction-support>LocalTransaction</transaction-support> a doimplementovanych drobnostiach podla runtime exceptions to uz funguje ako ma.

Zaznam v trace.log: 
[4/8/09 16:15:39:049 GMT+01:00] 00000023  3 UOW= source=com.ibm.ejs.j2c.ConnectionFactoryBuilderImpl org=IBM prod=WebSphere component=Application Server thread=[WebContainer : 3]
           Non-transactional resource adapter configured.  Forcing res-sharing-scope to UNSHAREABLE.

Zdravicko,

mam problem rozbehat svoj resource adapter. Narazil som na to ze ConnectionManager.allocateConnection vo WAS 6.1 funguje inak nez som si predstavoval.
Po 10 volaniach connectoru mi aplikacny server zahlasi com.ibm.websphere.ce.j2c.ConnectionWaitTimeoutException z dovodu vycerpania connections.
Nechapem preco sa matchManagedConnection zavola len v prvom pripade a az po vytvoreni noveho ManagedConnection. Zaroven mi pride divne, ze pomocou close na Connection prevolavam ConnectionEventListener.connectionClosed pre vsetky listenery, ale nikdy sa mi nezavola ManagedConnection.removeAppConnection.

PREDPOKLAD: Predpokladal som, ze klient resource adapteru poziada o connection nasledovne (zjednodusene):
  1. ConnectionFactory.getConnection(parametre):
       1.1. ConnectionManager.allocateConnection( ManagedConnectionFactory, parametre):
                 --- nasledujuce kroky vykona aplikacni server: ---
                 1.1.1. managedConnection = matchManagedConnection(parametre)
                 1.1.2. if (null == managedConnection) { 
                           1.1.2.1 managedConnection = new ManagedConnection(parametre) 
                           1.1.2.2 managedConnection.addConnectionEventListener(...)
      1.2. Connection c = ManagedConnection.getConnection
      1.3. return c;

REALITA: Co mna desi je zapis v logu:
  1. ConnectionFactory.getConnection(parametre)
       1.1. ConnectionManager.allocateConnection( ManagedConnectionFactory, parametre)
                 1.1.1. managedConnection = new ManagedConnection(parametre)
                 1.1.2. managedConnection = matchManagedConnection(parametre)
                 1.1.3. managedConnection.addConnectionEventListener(...)
...
  1. ConnectionFactory.getConnection(parametre)
       1.1. ConnectionManager.allocateConnection( ManagedConnectionFactory, parametre)
                 1.1.1. new ManagedConnection(parametre)
                 1.1.2. managedConnection.addConnectionEventListener(...)
...
  1. ConnectionFactory.getConnection(parametre)
       1.1. ConnectionManager.allocateConnection( ManagedConnectionFactory, parametre)
                 1.1.1. new ManagedConnection(parametre)
                 1.1.2. managedConnection.addConnectionEventListener(...)
...
