Hi,

I need to configure a connection pool in Weblogic 8.1 using an Oracle 9i driver to execute a stored proc that queries two (or more) different schemas in the same database.

I've tried Oracle's Driver(Thin XA), Weblogic's Oracle Driver (Type 2 and 4 XA), as well adding the jdbc driver from Oracle client to the weblogic classpath instead of using one of the proprietary drivers in weblogic.

The problem :

If I call a stored procedure from Weblogic's ejb container (using a java.sql.Datasource linked to connection pool), I cannot retrieve any information as a result of the following error ->
java.sql.SQLException: ORA-24777: use of non-migratable database link not allowed (if I use out parameters).

When I use a direct connection (not datasource) / call stored proc querying only one schema (using datasource), it works.

Please advice

Does someone know how to resolve this ? I am using XA driver using Oracle 9i/WebSphere MQ Version 5.2 in IBM WebSphere version 5.1.1.4. This problem shows up when I make a query to a different database instance connected via dblink.

java.sql.SQLException: ORA-24777: use of non-migratable database link not allowed
ORA-06512: at "XYZUSER.PKG_XYZ_QUERIES", line 528
ORA-06512: at line 1

ORA-24777: use of non-migratable database link not allowed

Cause: The transaction, which needs to be migratable between sessions, tried to access a remote database from a non-multi threaded server process.

Action: Perform the work in the local database or open a connection to the remote database from the client. If multi threaded server option is installed, connect to the Oracle instance through the dispatcher.

You may try to use a shared database link to solve the problem:
sample:
---------------------------------------
-- Create database link
create shared database link DB_LINK
connect to DB_APP identified by password1
authenticated by DB_APP identified by password1
using 'sid12345';
