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 may use names appropriate to your installation and any naming standards you have adopted. In many cases, you may use z/OS system symbols in your VTAM definitions, enabling a single set of definitions to be shared across multiple systems.

To define VTAM resources

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 may also want to 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 to be 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 outlined in your VTAM documentation.
