Issue/Introduction

What are the steps to revert back to ISFPARMS after implementing SDSF External Security with ACF2?

 

Environment

Release : 16.0

Resolution

To revert back to ISFPARMS, delete the inserted SAFDEF and CLASMAP that was inserted to enable SDSF external security. 

If following sample commands were used to insert the SAFDEF and CLASMAP records to enable SDSF external security,  delete the records using commands shown below. 

Sample INSERT of  the SAFDEF:

SET Control(GSO)
INSERT SAFDEF.SDSF ID(SDSF) MODE(GLOBAL) RACROUTE(REQUEST=AUTH,CLASS=SDSF) REP
F ACF2,REFRESH(SAFDEF)

Sample INSERT of the CLASMAP:

SET Control(GSO)
INSERT CLASMAP.SDSF RESOURCE(SDSF) RSRCTYPE(SDF) ENTITYLN(63)
F ACF2,REFRESH(CLASMAP)

Delete  the SAFDEF and CLASMAP records using these commands and make sure to issue refresh commands after delete:

SET C(GSO)
DELETE SAFDEF.SDSF
F ACF2,REFRESH(SAFDEF)

DELETE CLASMAP.SDSF
F ACF2,REFRESH(CLASMAP)

Also, ISFPRMxx needs to have AUXSAF(NOFAILRC4) specified to revert back to definitions in ISFPARMS and not go through ACF2 external security.
