RACF access control module
The RACF® access control module allows you to use RACF as an alternative to Db2 authorization checking for Db2 objects, authorities, and utilities.
You can activate the RACF access control module at the Db2 access control authorization exit point (DSNX@XAC), where you can replace the default routine. The RACF access control module is provided as an assembler source module in the DSNXRXAC member of prefix.SDSNSAMP.
The RACF access control module (DSNXRXAC)
does not provide full support of roles on z/OS® 1.7.
