3414676 - Semaphore List

• If a work process locks a particular resource, it sets a semaphore. Another work process that also wants to access it must then wait. In this case, the number of semaphores is displayed by SM50.
• Example: if any user while login (6: ROLL_ADM (roll administration)) semaphore will be locked, semaphore 6 is set
• Semaphores are used to synchronize concurrent access to shared resource (mostly shared memory) to avoid corruptions.
