ORA-02065: illegal option for ALTER SYSTEM

For 10.2.0.5, set up parameter value by :
alter system set sga_target= scope= sid=;

In 10g database, when trying to change SGA_TARGET parameter in spfile, “ORA-02065: illegal option for ALTER SYSTEM” occurred.

By swapping the order of “sid” and scope, it is working fine:
