DFS2493W A CENTRAL/EXPANDED STORAGE SHORTAGE EXISTS. VSO WILL BE ACTIVATED FOR areaname. BLOCKS REQ/AVAIL rrrrrr/aaaaaa
Explanation
The data entry database (DEDB) area was defined as a Virtual Storage Option (VSO) area. While opening the area, IMS determined that the amount of central and expanded storage available was not enough to satisfy the size of the area. Normal VSO processing is allowed for the area.
System action
The area is opened with the Virtual Storage Option.
Operator response
This warning message indicates that a potential VSO storage shortage exists. For the area indicated in the message, not enough VSO storage exists to hold the entire area. Accessed CIs are loaded into VSO, but it is possible that storage constraint problems, such as paging, might exist. If constrained storage represents a problem in your environment, you can remove the area from VSO by issuing the /VUN command. You can reactivate VSO processing for the area at any time by reissuing the /START AREA or by issuing an UPDATE AREA START(ACCESS) command.
