Issue/Introduction



When using the Explore MAP panel; to display GETVIS allocation there is a label that shows UNALLOCATED. Is this UNALLOCATED label referring to total unallocated space or just for this partition?

Environment

Release: XPRE..00100-7.1-Explore-Performance Management
Component:

Resolution

The UNALLOCATED label can refer to any UNALLOCAED space within any partition that any address begins and ends at.
 
For example:
 
S in the first column  is a shared storage area so this would be in the GETVIS area for all space allocations. The line below shows a SHARED GETVIS area that is unallocated of 832K

Space  Virtual--------                Total          Pfix                  Area       
  Id       Begin         End          V-Size  Limit--Used      Description
_S 006300000 006FFFFF     832K     0K      0K        UNALLOCATED
 
You can update the PSIZE or GETVIS values in the IPL to utilize this space.
