We currently run VMS 7.3, Oracle 8.1.7.4 OPS; box has 12gig of memory; SGA around 4gig; new server has 32gig of memory; Oracle is only thing running on servers. Should I increase SGA - Shared Pool and DB_BLOCK_BUFFERS - all my stats look good > 98%. Any suggestions will be appreciated. Is it true that having a too large SGA will cause performance issues?

Thanks.
