No Listener found for the Oracle Database after installing NW 7.3 with Oracle 11.2.03

318 Views

Hi,

After installing the Oracle 11.2.03 and NW 7.3 AS Java as per SAP Install guide, When I try to check saplikey -show I get error "Could not connect to DB".

When I check the Oracle Net Manager installed along with Oracle Installation I find no entry for Listener.

/nwa is also not opening - Error: 500 Internal Server error: Error Application error occurred during the request processing.

Apart from http://localhost:50000/StartPage no other pages are opening.

Should I create a Listener Manually?

Could not even login to Oracle DB via SqlPlus Error: ORA-12543: TNS: destination host unreachable.

Both my SQLPlus and DB server is in SAME Host, I don't understand why it say destination host unreachable?

Please help on this I tries both Oracle Support and SAP Support but of no use...
