control file version incompatible with ORACLE version

This ORA-00201 error is related with the Compatible version of Oracle instance and Controlfile Compatible.

To solve this error, set compatible parameter as follows then restart database.

SQL> alter system set compatible='19.0.0' scope=spfile sid='*';


SQL> shutdown immediate

SQL> startup

Or If your version is lower than 19 or 18, then set compatible parameter according to your database. If your Oracle version is 12c then you can set it 12 as follows.

alter system set compatible='12.0.0.0.0' scope=spfile;
