Error When Enabling Block Change Tracking For RMAN

Here is the common error you see when you enable it:

SQL> alter database enable block change tracking;
alter database enable block change tracking

ERROR at line 1:
ORA-19773: must specify change tracking file name

The error is due to we need set both db_create_file_dest

If not,
alter system set db_create_file_dest='+DATA' scope=both sid='*';

or manually use location:

alter database enable block change tracking using file 'location';

All these parameters are dynamic, no need to bounce DB
