Shared Memory and Semaphore Settings for Linux Systems

For Linux systems, the following semaphore and shared memory settings apply:

kernel.shmmax = 1073741824
kernel.shmall = 536870912
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 32768 65000

These values are set during installation. You do not have to set them.

The actual value for kernel.shmmax differs, depending on the amount of memory in the target host. This value adjusts itself dynamically when the OraSpt plan runs.
