No
Compared to SEMA_INDEX_MAX (currently 65,535) and reset to that value if larger. A warning message is written to the console, messages file, or both.
When the default number of sets is not enough. Generally changed at the recommendation of software vendors. No error messages are displayed when an attempt is made to create more sets than are currently configured. Instead, the application receives a return code of ENOSPC from a semget call.
For more information, see semget(2).
Unstable
Obsolete in the Solaris 10 release.
Specifies the maximum number of System V semaphores per semaphore identifier.
Signed integer
25
1 to MAXINT
No
The amount of space that could possibly be consumed by the semaphores and their supporting data structures is compared to 25 percent of the kernel memory available at the time the module is first loaded. If the memory threshold is exceeded, the module refuses to load and the semaphore facility is not available.
When the default value is not enough. Generally changed at the recommendation of software vendors. No error messages are displayed when an attempt is made to create more semaphores in a set than are currently configured. The application sees a return code of EINVAL from a semget(2) call.
Unstable
Obsolete in the Solaris 10 release.
Specifies the maximum number of System V semaphore operations per semop call. This parameter refers to the number of sembufs in the sops array that is provided to the semop() system call. For more information, see semop(2).

If the memory threshold is exceeded, the module refuses to load and the semaphore facility is not available.
When the default value is not enough. Generally changed at the recommendation of software vendors. No error messages are displayed when an attempt is made to perform more semaphore operations in a single semop call than are currently allowed. Instead, the application receives a return code of E2BIG from a semop() call.

When the default value is not enough. Generally changed at the recommendation of software vendors. No error message is displayed when an attempt is made to perform more undo operations than are currently configured. The application sees a return value of ENOSPC from a semop(2) call when the system runs out of undo structures.
