Hi

I have a problem with jdbc connection.

I have a cluster data base the instance name are inst1 and inst2, when I run a shells on an application server with jdbc some times I get and error and some times it works.

The error that I got on application server is

Exception in thread "main" org.springframework.transaction.CannotCreateTransactionException: Could not open JDBC Connection for transaction;

When i check on database server i got these erros

TNS-01184: Listener rejected registration or update of service handler "DEDICATED"
 TNS-01185: Registration attempted from a remote node

I attach a file with the tnsnames.ora, listener.ora and jdbc.properties

Sometimes it works and sometimes it doesn´t but if I stop one of the tow listeners it works or it I configure the jdbc directly to one instance it works.

Thanks for your help

Regards

Have you tried static registration?

Also, show the output of lsnrctl services

What about the tnsnames.ora from you client. What is that doing?

Finally I compared your server-side tnsnames.ora with mine and I am missing the following lines commented out:


DBSCM =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = cx011-vip)(PORT = 1521))
    (ADDRESS = (PROTOCOL = TCP)(HOST = cx012-vip)(PORT = 1521))
    (LOAD_BALANCE = yes)
#    (FAILOVER = ON)
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = DBSCM)
#      (FAILOVER_MODE = (TYPE=SESSION)
#      (METHOD=BASIC))
    )
  )

You have no registered instances on the Listener.
This could be easilly checked so:

% lsnrctl services

There are two methods to assure registration.
The easiest is:

Backup LISTENER.ORA file!!!!!!!

In ...\network\admin open listener.ora

see

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = D:\Ora10g)
      (PROGRAM = extproc)
    )
    (SID_DESC =
      (SID_NAME = test)
      (ORACLE_HOME = D:\Ora10g)
    )
  )

Add the entry
    (SID_DESC =
      (SID_NAME = test)
      (ORACLE_HOME = D:\Ora10g)
    )
with regard to the particular Oracle Home and SID Name.

Restart the listener:
c:>lsnrctl stop
c:>lsnctl start

The workaround is to use dynamic registration

The init.ora file parameters must be set to support dynamic service registration:
SERVICE_NAMES
INSTANCE_NAME
