Interactive Analysis Option 8 - PoolView

PoolView displays statistics about VSAM/LSR and VSAM/GSR buffer pool usage. The PoolView panel provides information about hit ratios, size and number of buffers, and total space requested. You can also display information about the data sets attached to a pool.

If no pool data is in the monitor data set, the PoolView option is not available.
