INNOVATION DATA PROCESSING ANNOUNCEMENTSIMPORTANT TECHNICAL BULLETIN FOR IAM VERSION 9.0 USERS WITH ACF2 SECURITY SOFTWARE
A problem has surfaced with IAM V9.0 that may cause a security exposure on IAM files for users that utilize ACF2 for dataset security.
On page 90-32 of the IAM V9.0 Manual, there are instructions for ACF2 users to add certain parameters to their ACF2 definitions so that ACF2 will properly handle the RACROUTE that IAM is issuing.
The manual incorrectly specifies that this is limited to IAM files that are used under IAMRLS or that are in DFSMS Extended Format. The correct information is that these parameters are necessary for all IAM Enhanced Format datasets. The change is due to changes in IAM V9.0 affecting how IAM datasets are opened internally.
The ACF2 parameters needed for all IAM users with ACF are shown below:
INSERT SAFDEF.IAM MODE(GLOBAL) ID(IAM) RB(SVC019 RACROUTE(REQUEST=AUTH CLASS=DATASET REQSTOR=IAMAVSOC) REP
