Abstract
The calculations for memory usage (%) and used memory (KB) changed in the memory status provider changed.
Content
Detailed information in the memory status provider (show memory command) changed with the fix for APAR IT44330. The primary changes are the calculations for memory usage (%) and used memory (KB).
If you use the data for either of these properties in scripts, you might need to modify your scripts to account for this change. Without any change to your system, memory usage reports a greater percentage.
The following table provides the new and previous calculations for details in the memory status provider.
| Memory detail | New and previous calculations |
|---|---|
| Memory usage | Now, the percentage of installed memory that is in use, which is Used/Installed. Previously, the percentage of total memory that was in use, which was (Total-Free)/Total. |
| Used memory | Now, the amount of installed memory in KB minus the amount of available memory, which is Installed-Available. Previously, the amount of total memory in KB minus the amount of free memory, which was Total-Free. |
If you believe that you have a memory growth issue, compare the values in the system usage status provider (show load command) between your previous and current fix packs. With this data, you can decide whether to open a service ticket with IBM Support.
