Link security

Edit online

The target CICS system checks link security against requests from the server using the server region’s user ID.

These security checks cover the following:

  • Transaction attach security (when attaching the mirror transaction).

  • Resource and command security within the Server application program.

If you have transaction and program security that is enabled in your CICS region, make sure that the server user ID can access the mirror transaction and the CICS Server program. Also, if the CICS Server program accesses a protected resource, make sure the server user ID can access the same protected resource.
