Issue/Introduction

After putting on the current ACF2 V16 maintenance(which includes  LU00294 and LU02625), DB2, CICS or other regions that utilize the DB2 secondary authid exits may abend or experience DSN9029I errors as follows:

DSN9029I -DSNV DSN9SCN7 FAILURE WHILE PROCESSING A COMMAND

 

Environment

Release : 16.0

Component : CA ACF2 for z/OS

Resolution

DSN3@ATH and DSN3@SGN exits need to be relinked with latest version of ACF00SSL. 

To reassemble and link the latest exits, the source can be found in CAX1MAC0(ACF3@ATH) and CAX1MAC0(ACF3@SGN). The source is in base ACF2 macro library, not the ACF2/DB2 macro library. 

Notes: If PTF LU00294 has not been accepted when relinking the DSN3@ATH andDSN3@SGN secondary authid exits, the ACF2 CAX1LOAD library should be concatenated ahead of the AAX1MODx datasets so the new ACF00SSL module will be picked up. If only a linkedit is needed(a re-assembly is not required), the DSN3@ATH and DSN3@SGN load modules can be used as input to the linkage editor- but must be placed as the last include statement not the first include statement.

With LU00294 the linkedit statements for DSN3@ATH and DSN3@SGN have an additional include statement for SAFFBSC6.
