Modify init.ora

[shuan.tay\(PCI鄭祺勛\)]

Hi! DBAs,   If I modify the "Process" in init.ora after database was created and running for quite a long while, is it true that the maximum of the process will increase as what i changed? do i need to change anything?   init.ora will be used everytime the database start, right? or just for the initialization for db creation?   thanks in advance.
