Why i get this error ORA-00823: Specified value of sga_target greater than sga_max_size.

Actually i was doing some practice on that time i set my sga_target to some values after that i closed the database.

Next day when i was opening the database i get this error ORA-00823: Specified value of sga_target greater than sga_max_size. 

After that what i have done i am showing it.
