RE: SGA QUESTION

You suck up half of that memory easy for Oracle and NT would run just fine, as long as there aren't a whole bunch of other applications running on the server!

Does anyone have an idea of what percentage of total memory should be reserved for NT? Say I had 600m of memory available. How big could my SGA be and still have NT run properly?

Hello,

        The upper limit for a server running NT is 2gb, because usually only 4gb of
memory can be installed. However, I believe that with the patch installed, enabling NT to go above 4gb of ram, it will also increase the upper limit. KK

Hi all,

I don't remember the limit, but there *is* an upper limit on the amount of memory that a single process can address in NT (was it 2Gb?). Since the architecture of Oracle on NT is a single-process-multi-threaded one, and all of the SGA and PGA is actually within this process space, I believe that you may be bumping this upper limit....

Maybe someone with a deeper understanding of NT can chip in (Anita?)
