Hi All, Wanna share the solution,
If you look the error Error Caught while creating a connection in EPP dB: = org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory, cause: Io exception: Connection refused(DESCRIPTION=(TMP=)(VSNNUM=135290880)(ERR=12505)(ERROR_STACK=( ERROR=(CODE=12505)(EMFI=4)))) ORA Error Code "12505" means "TNS:listener could not resolve SID given in connect descriptor" After correcting every thing is woking fine ..

It is the JDBC driver for the PostgreSQL database. You do not need it if you are connecting to an Oracle database - but, of course, you need the Oracle equivalent, which I am sure you already have if you have managed to make 'single' connections, as you say. I cannot help you with your problem, but the key words in the error output would seem to be: 'Connection refused'. Make sure that *all* your connection details are specified correctly.
