Administering CICS Web support

When you have configured CICS® to perform a variety of CICS Web support tasks, and started to respond to requests from Web clients, you might need to carry out some administrative activities to manage your CICS Web support structure and to provide appropriate handling for requests if a resource is unavailable.

Administration for CICS Web support is facilitated by having URIMAP definitions to manage your HTTP requests. URIMAP definitions enable you to:
  • Redirect or reject specific HTTP requests dynamically in a running CICS system, if the resources needed by those requests (for example, a CICS program) are not available.
  • Have virtual hosts created by CICS, which can be managed using CICS commands.
If you do not have URIMAP definitions, you can administer CICS Web support at the level of a TCPIPSERVICE resource definition, which manages all requests on a particular port, but managing at the level of the URIMAP resource definition gives greater control and granularity.
