Checking memory resources

To check memory resources:

1. Do one of the following.
   • Type sar -p and press Enter.
   • Type sar -p 5 50 and press Enter.

     The system displays the Memory Resources screen.

2. Check the column labeled vflt/s. Note if this value is consistently close to or greater than 50.00.
3. Type sar -g or sar -g 5 50 and press Enter.

   The system displays the Memory Resources screen with new information.

4. Check the column labeled pgscan/s. Note if this value is consistently close to or greater than 100.
5. Type sar -r and press Enter.

   The system displays the Memory Resources screen with new information.

6. Check the column labeled freemem. Note whether this value:
   • Is consistently close to or less than 100 or
   • Consistently decreases and does not regain memory for multiple days
7. If two or more values consistently follow the pattern that follows, then reduce memory usage.
   • vflt/s > 50.00
   • pgscan/s > 100
   • freemem < 100

Note:
Besides memory overload, processes being created and terminated regularly will also cause vflt/s to increase. If this is the case, memory may be sufficient, but the creation of processes is forcing the operating system to page processes to disk and back into memory. When processes are paged, they respond more slowly, and speech processing may be interrupted.
