Situation Description

Alert (warn) when a critical-level storage shortage signal (an ENF Event) has been raised. One of the following Storage Shortage Types will be displayed with a critical-level storage shortage alert:

  1. Pageable_Storage
  2. Auxiliary_Storage
  3. Available_Frame_Queue_Shortage

Possible cause of the storage shortage condition may be one or more address spaces which are allocating and fixing too much storage or using too much auxiliary storage.

 

Suggested Actions

Identify address spaces representing the most significant cause of the storage shortage. From the Real Storage workspace, navigate to the Storage Shortage Alerts workspace and Storage Shortage Details workspace. This workspace will provide the top-twenty contributing address spaces. Consider stopping or canceling one or more of these address spaces to relieve the storage shortage. Adding auxiliary paging space may be an option for alleviating auxiliary storage shortage conditions.

Note that SRM, with guidance from PARMLIB OPT settings, will take steps to relieve the storage shortage. Action may only be required if the critical storage condition persists.
