Configuring Oracle

AtomikosDataSourceBean example

AtomikosDataSourceBean ds = new AtomikosDataSourceBean();
ds.setUniqueResourceName("oracle");
ds.setXaDataSourceClassName("oracle.jdbc.xa.client.OracleXADataSource");
Properties p = new Properties();
p.setProperty ( "user" , "java" );
p.setProperty ( "password" , "java" );
p.setProperty ( "URL" , "jdbc:oracle:thin:@localhost-xe:1521:XE" );
ds.setXaDataSourceProperties ( p );

Notes

Oracle 9.2 and Oracle 10 are both working fine. It is highly recommended to use the latest Oracle 10 JDBC driver even when connecting to Oracle 9 databases.

Oracle's DBMS must be configured with extra packages before you can use it with XA:

grant select on sys.dba_pending_transactions to <user name>;
grant select on sys.pending_trans$ to <user name>;
grant select on sys.dba_2pc_pending to <user name>;
grant execute on sys.dbms_system to <user name>;
