ERROR at line 1:
ORA-01503: CREATE CONTROLFILE failed
ORA-01504: database name 'shaikcl' does not match parameter db_name 'shaikcl'

Cause of the problem
The error message already shown the database name in controlfile does not match with db_name parameter inside spfile/pfile.

Solution of the Problem
Be sure what would be your database name. In this example with message 'shaikcl' does not match parameter db_name 'shaikcl'
I see in controlfile the database name is specified shaikcl but in the spfile/file it is specified as shaikcl. If you are sure there is wrong entry inside spfile/pfile then you have to edit the db_name parameter in the spfile/pfile.
-If you have pfile then open it with text editor and edit db_name initialization parameter.
-If you have default spfile then use ALTER SYSTEM SET DB_NAME=real_name scope=spfile
and restart your database.

If you are sure that your spfile/pfile db_name parameter is correct and there is wrong setting on controlfile then edit the control file text script. Change database wrong_database_name to database right_database_name in the script.
