As a beginner in the field, I have a starting question:
My ORACLE DB is installed on Windows NT along with a user application. The app runs well but if I want to enter svrmgr23 this error appear:
ORA-09352: OracleService (SID) has not been started.
In services the 3 Oracle components start automatic and I've seen ORACLE_SID set.
What's the mater ?
