How to define Environment variable ORACLE_SID to display DB Console ?
Folks,
Hello. I have just installed Oracle Database 11gR1. In order to display Database Control Console page, I run the following command at Oracle_Home/bin directory:
./emctl start dbconsole
But the error message comes up:"Environment variable ORACLE_SID not defined. Please define it."
I have specified "OracleDB" as SID during the Database installation, but still get this error.
Can any folks tell me: How to define Environment variable ORACLE_SID in order to display DB Control Console ?
