#not started, which means that we are connected to an idle routine, which is usually caused by an incorrect oracle_home configuration in the static service name or incorrect SID configuration.
Check the listening file, found that the oracle_home path last one more '/'

SID_LIST_ORA11 =(Sid_list=(Sid_desc=(Global_dbname=ora11) (Oracle_home=/u11/app/oracle/product/11.2.0/dbhome_1) (Sid_name=ora11)) (Sid_desc=(Global_dbname=dupdb) (Oracle_home=/u11/app/oracle/product/11.2.0/dbhome_1/) (Sid_name=dupdb)) )

Remove the '/' from the above code.

In addition, we can also test if we are connected to an instance of the boot instance, or to an idle instance, by Sqlplus Xxx/[email protected] as SYSDBA.
