Screen Description
The Scratch Manager Detail screen displays information about scratch area activity, including access statistics and page-use statistics.
You can determine the number of pages assigned to the scratch area by adding the number of pages currently in use (Pages Allocated) to the number of pages available (Pages Free).
When the scratch is assigned to storage, some output fields will display a 0 value. For more information, see the CA IDMS System Generation Guide.
What To Look For
Add the number of pages read (Pages Read) to the number of times a requested page was found in the scratch area buffer (Found in Buffer). Compare this sum with the number of times a page was forced out of the buffer for another task I/O (Pages Stolen). If Pages Stolen is high compared to this sum (greater than 50%, for example), you should increase the size of the scratch area buffer in the DMCL.
The following entities may show up as frequent users of the scratch area:
