That’s right Mahir. Actually in this case the first thing you check is ORACLE_SID. When you see it’s correctly set and the instance is running on the OS level, you need to check ORACLE_HOME variable and remove the last character which is slash “/”

Hi Kamran!

You are right, this is reason of connection idle instance.
Thanks for share !

Mistake ORACLE_SID is reason of connection idle instance, too.

[oracle@oel62-x64 /]$ echo $ORACLE_SID
admdb

[oracle@oel62-x64 /]$
[oracle@oel62-x64 /]$ sqlplus / as sysdba
