Using NSKCOM to Monitor and Alter Swap Files
When NSKCOM starts, it automatically displays your current configured swap files.
The NSKCOM opening banner does not display default swap files.
In the above example:
•
The numbers 0, 1, 2, and 3 represent the CPUs.
•
The threshold indicates the usage threshold at which an EMS message is
generated. If blank, the file has the default threshold of 85 percent.
•
NSK- is the NSKCOM prompt.
2. Determine the size and usage of your kernel-managed swap files.
> NSK- STATUS SWAPFILE
This command displays a swap file’s total number of processor pages, as well as the
pages that are allocated and available, as follows:
3. Display statistics for each processor, using the STATUS KMSF command.
