The sshmseg parameter specifies the maximum number of attached shared memory segments per process. A process must attach a shared memory segment before the data can be accessed.
This parameter is specified in /var/sysgen/mtune/shm.
Value
Default: 100
Range: 1-SHMMNI
When to Change
Keep this parameter as small as possible to limit the amount of memory required to track the attached segments.
Increase this parameter if processes need to attach more than the default number of shared memory segments at one time.
