Common Communications Interface › SNA Configurations › Define VTAM Resources

Define VTAM Resources

The procedure uses the illustration in SNA Configurations as an example. It uses CCIA and CCIB as host and VTAM resource names. However, you can use names appropriate to your installation and any naming standards you have adopted. In many cases, you can use z/OS system symbols in your VTAM definitions, enabling a single set of definitions to be shared across multiple systems.

Follow these steps:

1. Define the local CAICCI VTAM applications on each computer.

   Define CCIA as follows:

   CCIHOST1 VBUILD TYPE=APPL
   CCIA     APPL   ACBNAME=CCIA,
                   AUTH=(ACQ,NOTSO)
   

   Define CCIB as follows:

   CCIHOST2 VBUILD TYPE=APPL
   CCIB     APPL   ACBNAME=CCIB,
                   AUTH=(ACQ,NOTSO)
   

   Depending on your network configuration and site standards, you canalso include other VTAM parameters such as CERTIFY, EAS, and VPACING.

   Note: For information about VTAM parameters, see your VTAM documentation.

2. If you are not using advanced peer-to-peer networking (APPN) with DYNLU=YES, define a VTAM cross‑domain resource for each remote CAICCI system that is accessed from CCIA and CCIB.

   Note: If you are using SNA exclusively for PC to mainframe connectivity, you can bypass this step.

   Define the following VTAM cross‑domain resource on host CCIA:

   CCICDRS1 VBUILD TYPE=CDRSC
   CCIB     CDRSC  CDRM=CDRMB,ISTATUS=ACTIVE
   

   Define the following VTAM cross‑domain resource on host CCIB:

   CCICDRS2 VBUILD TYPE=CDRSC
   CCIA     CDRSC  CDRM=CDRMA,ISTATUS=ACTIVE
   

3. Activate the new VTAM resources.

   On CCIA, issue the following commands:

   V  NET,ACT,ID=CCIHOST1
   V  NET,ACT,ID=CCICDRS1
   

   On CCIB, issue the following commands:

   V  NET,ACT,ID=CCIHOST2
   V  NET,ACT,ID=CCICDRS2
   

4. Add these new resource definitions to your VTAMLST ATCCONxx member so that they become active when VTAM is initialized.
5. Define other VTAM resources such as cross-domain resource manager (CDRM) major nodes, channel-to-channel (CTC) devices, and network control program (NCP) major nodes for your configuration.

   Note: For information about VTAM resource definitions, see your VTAM documentation.

   Note: Before CAICCI can use VTAM generic resources, you must have performed the setup that is outlined in your VTAM documentation.
