If your database has "Automatic Shared Memory Management" enabled you should adjust the parameter SGA_TARGET instead.
Read more about Oracle memory architecture here:
http://download.oracle.com
no matter which method you use, increasing the max_sga_size will involve a bounce of the database. set the sga_max_size to a large number so that as memory requirements increase, you can increase the sga up to the max without a bounce.
just a note: if the database is in a non-global zone on a solaris 10 machine, you cannot use dynamic memory stuff, you will allocate the max size straight off, so thought about sizing is required.

Directly in SPFILE:
SQL>ALTER SYSTEM SET sga_max_size=896M SCOPE=BOTH;
Using Parameter File:
SQL>create pfile='/u02/init.ora' from SPFILE;
Adding or changing the parameter there
SQL>shutdown immediate
SQL>startup pfile=/u02/init.ora
After some time create a SPFILE and remove the existing one.
Precreating a parameter file is a gut practice
