Define CA-L-Serv to VTAM

This procedure is necessary only if you plan to use VTAM to support communication between copies of CA‑L‑Serv executing on different systems.

Follow these steps:

  1. Create a major node member in your SYS1.VTAMLST data set using the CCCSOPTN member SAMPACB as a template.
  2. Specify an APPL statement for each local instance of CA‑L‑Serv that uses VTAM to communicate with other instances of CA‑L‑Serv executing on other z/OS images.
  3. Identify the new major node to VTAM by adding the member name to the ATCCONxx member of your SYS1.VTAMLST. This ensures that the corresponding APPL is activated when you start VTAM.
  4. Define the cross‑domain resources to VTAM by adding the corresponding CDRSC definitions to your SYS1.VTAMLST data set.

    Notes: The SAMPACB definition that the YourdeployHLQ.CCCSOPTN data set provides can be used for either LU 0 or LU 6.2 communication.

  5. Your new definitions can be activated without having to restart VTAM by issuing V NET,ACT,ID=…. commands against the newly‑defined resources.
