How to Remove characters from the ACF2 PWPHRASE GSO SPECLIST parameter

Products

• ACF2 - z/OS

Issue/Introduction

Trying to clear the SPECLIST field i the PWPHRASE GSO record. The commands

ACF
SET CONTROL(GSO) SYSID(****)
CHANGE PWPHRASE SPECLIST()

Did not work.  There are characters that need to be removed from the current SPECLIST. The current is SPECLIST(% & * - _ ! = | : . ?). The security group needs to change the policy to only an underscore ( _ ) to be the only valid special character.

What is the proper command to reset the SPECLIST  to ()  and then add the _ back in?

 

Environment

Release : 16.0

Component : ACF2 for z/OS

Resolution

To remove fields from the SPECLIST you can do a CHANGE with the DEL parameter. To add SPECLIST(_) just the CHANGE command can be issued. For example:

SET CONTROL(GSO) SYSID(****)
change pwphrase SPECLIST(& *) del
