We have grid control 11g enterprise manager, and 11g agent on machibe where database A stands.
recently we did migartion of database A to database B (that is on another machine) with expdp/impdp, and shutdown database A.
Now, we want to compare the performance between database the old A and the new B and for that we want to access the historical grid information on A.
is is possible to get access to this information without opening the A database? (we don't want to open the old database/start listener because we afraid of someone to log on accidently to the old db)
