Tivoli Storage Manager uses shared memory resources for internal operations. To estimate the total amount of shared memory, in kilobytes, that your server may need, use the following formula:
+--------------------------------------------------------------------------------+ | memory = 512 + (maxSessions x 256) + logPoolSize + bufPoolSize | +--------------------------------------------------------------------------------+
Where:
After you have estimated the value, round it up to the nearest multiple of 8MB. If you receive an error message indicating a lack of memory, increase the shared memory.
Note: | Your estimate is only an approximation. Many environmental factors can influence the shared memory requirements. In addition, other applications may use shared memory, and you must also account for their requirements when you adjust your kernel configuration. |
After you have estimated the shared memory requirements, ensure that your kernel configuration contains the correct value. See Viewing and Modifying the Kernel Configuration for details.
