i'm trying to reconfigure the OMS since i'm new in this company.
and i don't have any previous data from the old DBA except the sys user ans password which is a sysdba user.

i recreated sysman user and i'm trying to reconfigure Oracle Management server, (after trying all current user in vain) i'm still getting the same message:
"No repository was found for product "/com/oracle/Sysman/EM/EMSystem" in schema for user "SYSMAN" "

or whatever user i tried to connect with.

i need either to know the repository user or to modify it.

please help!!
