Tivoli Storage Manager uses semaphore resources to control its internal operations. To estimate the total number of semaphores that the server may need, use the following formula:
+--------------------------------------------------------------------------------+ |semaphores = 60 + (2 x maxSessions) | +--------------------------------------------------------------------------------+
Where maxSessions is the maximum number of concurrent client sessions.
For example, if you expect to have up to 15 client sessions active at the same time, TSM needs approximately 90 semaphores.
Note: | If you have other applications that use semaphores, you must account for their requirements also when adjusting your kernel configuration. |
After you have estimated the number of semaphores, ensure that your kernel configuration contains the correct value. See Viewing and Modifying the Kernel Configuration for details.
