Implementing CICS web error program support

If your site is planning to use the Abend-AID for CICS support for the CICS Web Interface, We recommend that you use the CICS Web error program, DFHWBEP. This program is an IBM user-replaceable module driven by CICS Web support when there is a failure in the processing of a Web request by a CICS Web TCPIPSERVICE for the CICS Web Interface. Using DFHWBEP allows modification of the HTTP response issued by CICS or the display of an alternative message.

DFHWBEP is used to take CICS transaction dumps for errors occurring during processing of Web requests that otherwise might not be taken. This module ensures that a CICS transaction dump is available with the correct information to enable speedy problem resolution. Without it, a transaction dump may not be taken, and information written to the CICS JESLOG may not be readily available.

A sample DFHWBEP module is supplied in the Abend-AID Common Components target sample library (SKAZSAMP) member FXWEBP. This sample program is not supported by BMC and is intended as an example only. Each installation needs to make its own determination regarding if and how this module is used.

Note the following main considerations for this module:

  • The load module name must be DFHWBEP.
  • The module must include EXEC CICS IGNORE CONDITION SUPPRESSED. This command statement prevents the AEXW condition when Abend-AID for CICS suppresses IBM transaction dumps.
  • Field WBEP_ABEND_CODE contains the abend code that is to be issued.

Activate DFHWBEP

To activate the CICS Web error program, do the following:

  1. Assemble and link-edit DFHWBEP to a CICS DFHRPL library.
  2. Define DFHWBEP in a CICS RDO definition.

For further information, refer to the discussion about the CICS Web error program in the IBM manual, CICS Internet Guide, for CICS Transaction Server for z/OS.
