Spotlight on Oracle 10.10 - Release Notes

Page Reads Alarm

This alarm is activated when the number of pages being read in exceeds a threshold. Sustained high paging rates can adversely effect the performance of a system.

When this alarm is current, you should:

  • View the Processes page on the Processes drilldown to see which process is causing the paging. Look at the Faults/s column to determine the cause of paging.
  • View the Page File Transfers chart on the Paging Activity page of the Memory drilldown. This shows how long the high paging in has been occurring. Short periods of high paging are acceptable, but if the paging rate is high for a sustained period, there may be a problem with the system.
  • Consider adding more physical memory to the system.
  • Stop unnecessary services and processes on the system.
