JDBC connection to Oracle Clustered

Question

I would like to connect to a clustered Oracle database described by this TNS:

 MYDB=
 (DESCRIPTION = 
    (ADDRESS = (PROTOCOL = TCP)(HOST = host1)(PORT = 41         


        

Answer 1

Apparently you can do this

jdbc:oracle:thin:@(DESCRIPTION=(LOAD_BALANCE=on)
(ADDRESS=(PROTOCOL=TCP)(HOST=host1)
(PORT=1521))
(ADDRESS=(PROTOCOL=TCP)(HOST=host2)
(PORT=1521))
(CONNECT_DATA=(SERVICE_NAME=service)))

Answer 2

You can use this format, unless you make use of JTA transactions. In that case you must use some different setup. See http://forums.oracle.com/forums/thread.jspa?messageID=2860653&#2860653 (applies for BEA Weblogic, but I think it also applies for other setups and application servers)
