Hi,
In hyperic UI go to Oracle11g server, press "Tools" menu -> Configure server
In configuration properties fill:
jdbcURL - jdbc:oracle:thin:@<ORACLE_Machine_IP>:<Oracle_Port>:<OraSid>
next fields are credentials for connection to Oracle DB
jdbcUser - oracle_user
jdbcPass - oracle_pass
How to detect oracle connection details (port and sid) - go to oracle_home_directory (e.g. C:\Oracle\product\11.2.0\dbhome_1\NETWORK\ADMIN) in tnsnames.ora you can find all relevant info.
You can also detect sid in windows service (e.g. ora11202)
Good luck
