The explanation of what these are has been given, I'll answer the question
about how it relates to the SGA. Basically, you have to have shared memory
max segment set to be larger than your total SGA or you will a. not be able
to start Oracle or b. get a whole slew of memory errors and Oracle
reads/writes to memory areas beyond what the OS will allow. This will
either crash your database or fill up your file system with trace files and
core dumps. Been there, done that, ain't goin back.
