I an running ORACLE 8i/9i 64bit on HPUX 11.11. What is the combined total RAM ORACLE will not go beyond of all the SGA instances? I have set SHMMAX to the maximum allowed on my machine (4gb). The archives mention 32 bit oracle as having a limit but I was wondering about 64 bit. Thanks.

Here is an excerpt from the archives.

If you are

> 32-bit Oracle is very limited as far as RAM usage.
