Issue/Introduction

After a Detector for Db2 for z/OS (PDT) datastore has reached full size, as the quantity of transactions to capture reduces, is there any way to detect
how full a Detector datastore really is? In other words, how to know to what smaller size can resize the datastore? Will LISTCAT show anything meaningful?

Resolution

Since the datastore is a collection of VSAM datasets, you can use the LISTCAT command to see its space utilization information.
The IDCAMS LISTCAT ALL will show you the high allocated and high used RBA.
The percentage of space used can be calculated as: (Hi-USED / HI-ALLOC) * 100 = %Used
