Verifying a multiple-domain subarea network

Verify that your multi-domain subarea network functions properly after you verify a VTAM® network.

Before you begin

Perform the steps Verifying a VTAM network for each domain in your network. After you have done this, make a list of the most important normal and backup operations in your network, and verify each of them one at a time. Then verify the network over a length of time, as in normal operation.

Procedure

To verify that your multiple-domain, subarea network functions properly, do the following steps:

Activate cross-domain paths and links, cross-domain resource managers (CDRMs), and cross-domain resources (CDRSCs).
Verify cross-domain sessions by exchanging requests across domains, between terminals and hosts, and between application programs.
Verify the NetView® program, if it is installed.
Verify host backup using a channel-attached, shared NCP.
Verify host backup over a cross-domain link.
Verify automatic SSCP-SSCP session restart.
Halt VTAM in each domain.
