Guys
I am installing SAPR3 system on Windows. After the installation is complete, while running the post installation tasks I am seeing the following error. The database is up and running and the listener is up too. I can connect to the database from sqlplus. The ORACLE_SID is also set, Can you tell me what I have to do get over this problem ?
