Issue:
I will be upgrading to CA ACF2 for z/OS r16 in the near future. I heard that the rules will be going above the bar in this release.
I would like to find out how much storage i could reclaim from ECSA - I have many resident rules.
Are there any utilities available that can calculate the storage used for each resource type code?
Resolution:
A new utility program, ACFSTGUT, can be installed with PTF RO84661.
This program will run on ACF2 R15 and list all resident resource types and the amount of storage they use in eCSA.
Use this JCL to run the utility.

The output from the utility looks like this...
