My Confusion is
If i allocated 12 GB Memory for sybase than how many types memory should configured
eg. sp_configure 'max memory' 6291456 (2K)
what about other memory should configure and what size ,like proc cache, statement cache, descriptor counts, data caches etc.
Also i got from one of scn blog mentioned "procedure cache should 30 to 40 % of Max memory" but m still confused about other memory, so please clarify what should i do ?
