Managing User Defined Extensions

User Defined Extensions (UDX) support allows you to request implementation of a customized cryptographic callable service. This support is available with a special contract with IBM for the CCA coprocessors. User Defined Extensions are ICSF functions developed for your installation with the help of IBM Global Services. Contact IBM Global Services for any problems with UDX.

You must define your routine to ICSF in the Installation Options Data Set. For more detailed information on the Installation Options Data Set and the UDX keyword, see z/OS Cryptographic Services ICSF System Programmer's Guide.

The UDX callable service load module is loaded during ICSF startup. Use the ICSF panels to perform UDX authorization processing.

You can perform these tasks:

Select option 9, UDX MGMT, on the ICSF Primary Menu panel.

Once you have selected option 9, this panel is displayed:
