Issue/Introduction
When upgrading to ACF2 for z/OS R16, the rules will be going above the bar in this release.
How much storage can be reclaimed from ECSA?
Are there any utilities available that can calculate the storage used for each resource type code?
Environment
Release: ACF2 R15
Resolution
The 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:
//********************************************************************
//* RESOURCE RULES IN STORAGE REPORT SORTED LARGEST TO SMALLEST *
//********************************************************************
//JS030 EXEC PGM=ACFSTGUT
//STEPLIB DD DISP=SHR,DSN=HLQ.CAX1LINK
//********************************************************************
//* OUTPUT CAN GO TO A DATASET OR OUTPUT QUEUE *
//* SYSPRINT DD SYSOUT=* *
//********************************************************************
//SYSPRINT DD DSN=HLQ.ACFSTGUT.SYSPRINT,DISP=(,CATLG,DELETE),
// DCB=(BLKSIZE=1330,LRECL=133,RECFM=FB),SPACE=(TRK,(5,5)),
// UNIT=SYSDA
//
The output from the utility looks like this:
