Configuring CICS

Edit online

Configure CICS by modifying the CICS started tasks JCL, the System Initialization Table (SIT), and the DFHCSD file.

Procedure

  1. Add the hlq.SAVZCLOD library to the DFHRPL concatenation in each CICS region that you want to connect to server.
  2. Use the CEMT INQUIRE IRC command to verify that the CICS interregion communication (IRC) facility is open.
    To start IRC at CICS system startup, ensure that the IRCSTRT=YES parameter is in the SITPARM for the CICS region.
  3. Update the DFHCSD file by performing the following steps:
    1. For each CICS region, modify and submit the AVZCICSD job that is in hlq.SAVZCNTL data set:

      • Update the DEFINE CONNECTION and DEFINE SESSION values to match the definitions that you specified in the Data Virtualization Manager configuration member. The GROUP value is the CICS GROUPNAME and does not need to match the GROUP name that is defined for the server. By default, 21 sessions are defined. Set this value to the maximum number of concurrent transactions for a single instance of server. The maximum value is 250.

      • Change the name of the hlq.FILEA data set to the FILEA VSAM data set name. This VSAM file is used when you verify access to CICS data.

      The member contains additional information about modifying the job.
    2. Update LIST(YOURLIST) to match the startup group list for the CICS region.
    3. Review more comments in the JCL notes section for additional considerations. Define all of the definitions in the hlq.SAVZCNTL(AVZCICSD) member.
