Setting up the z/OS-based client

Use the following procedure to set up the z/OS®-based client.

Procedure

  1. Install and set up the NACT transaction.
  2. Edit the DFH0CBRX or DFH$BRXC sample to pass the netname of the CICS® region where the bridge client program (DFH$BRLC or DFH0CBRL) is installed. Compile and link the COBOL or C language programs DFH0CBRX or DFH$BRXC, using a Language Environment® conforming compile, ensuring the library containing the DFH$BRSH and DFH0CBRA copybooks is accessible. Ensure also that the CICS supplied SDFHEXCI data set is concatenated to SYSLIB for your compile step. Place the output load modules in an appropriate z/OS library.
  3. Translate, compile and link the COBOL or C language programs DFH0CBRL, and DFH$BRLC, using a Language Environment conforming compiler, ensuring the library containing the DFH$BRSH and DFH0CBRA copybooks is accessible. See Device dependent support for guidance on translating and compiling CICS programs.

    Add the load library containing the load modules to the RPL concatenation of your CICS startup job.

  4. Create and install a CONNECTION resource definition to define the interface between CICS and z/OS that will be used by the EXCI request. See Defining connections to CICS and Introduction to the external CICS interface for an introduction and guidance on how to use of the EXCI interface.

What to do next

Run the sample programs from a z/OS-based client.
