Hello, based on Metalink Certify table Oracle 8.1.7.3 is not supported to be monitored in EM 10 Grid. Only databases started from 8.1.7.4. Has anybody tried to set up 8.1.7.3 database in EM 10 GC (Rel 2, 3)? If it is not supported is there any chance to develop a plug-in to monitor 8.1.7.3 and even 7.3.4 within EM 10 GC (Rel 2, 3)? Has anybody have such experience?
