i am unable to startup database in SQL after i tried to increase the memory size .
i have followed the below process
SQL> conn sys/manager as sysdba; Connected. SQL> alter system set processes=1000 scope=spfile;
SQL> alter system set sga_target=360M scope=spfile;
SQL> alter system set sga_max_size=360M scope=spfile;
SQL> shutdown; Database closed. Database dismounted. ORACLE instance shut down. SQL> startup; ORA-01078: failure in processing system parameters ORA-00838: Specified value of MEMORY_TARGET is too small, needs to be at least 3 72M
..i tried changing MEMORY_TARGET with different values but unable to start up
i am using a 32-bit machine with windows-vista operating system
