Re: Need Help: Linux Kernel-Parameters SHMMAX,SHMMNI,...

The maximum size of a single shared memory region is specified by the LINUX parameter SHMMAX. An SGA that is 2048 KB can use four shared memory regions of 512 KB each.
If the size of the SGA exceeds the maximum size of a shared memory segment (SHMMAX), Oracle8 attempts to attach more contiguous segments to fulfil the requested SGA size. SHMSEG is the maximum number of segments that can be attached by a process. To attach the segments at contiguous addresses, SHMMAX must be set to its maximum value on systems where its size is limited.
Note:
Intimate Shared Memory (ISM) may cause problems when SHMMAX is smaller than the database SGA size.
