CA Database Management Solutions for Db2 for z/OS
and the IBM Db2 for z/OS DISALLOW_SSARAUTH Subsystem Parameter
IBM PTF UI66853 enables a new online Db2 12 for z/OS subsystem parameter (ZPARM)
DISALLOW_SSARAUTH. This ZPARM controls the authorization of allied address spaces that are connecting to Db2. The default setting is NO, which preserves the existing behavior and there is no change required for allied address spaces. When set to YES, Db2 prevents the user address spaces from setting a Db2 address space as a secondary address space. If you plan on setting DISALLOW_SSARAUTH to YES, note the following impact for Version 20.0 and Version 19.0 of the CA Database Management Solutions for DB2 for z/OS:
- Version 20.0 is compatible with this change. However, you must apply the following maintenance before you change DISALLOW_SSARAUTH to YES:
SO10442
SO10906
SO10907
SO11323
SO11983
- Version 19.0 is not compatible with this setting and there are no plans to provide this support. End of support for Version 19.0 is planned for September 2020. Without the following maintenance the products may fail with the system ABEND 0D7 interruption code 25 or unpredictable results can occur. After applying the following maintenance, the products will prematurely end with error message: GEN0461E DSNZPARM DISALLOW_SSARAUTH not supported on SSID: ssss
SO10790
SO11158
SO11159
SO11160
To continue using the products on this subsystem with DISALLOW_SSARAUTH set to YES, upgrade to Version 20.0 of the CA Database Management Solutions for DB2 for z/OS.
