I have a 10.2 oracle database. The startup of this database works fine. Starting the listener works fine too (no errors).
When i run a Sqlplus session in local way (setting the ORACLE_SID env var before launching sqlplus) it works fine too.
But when i try "sqlplus system/password@SID" the server doesn't respond :
nothing ... no error codes.
When i try TOAD, it's the same thing ... no response
When i try Oracle Enterprise Manager the doesn't respond too.
Notice that Oracle is not "installed" on this dev machine but "copied-pasted" from another where everything works fine. I also export the registry entries for oracle from the working machine to the dev machine, but it does'nt work anymore.
any suggestions ?
