PGAIN and NEVAC EE Line Activation Failures

A line status of PGAIN indicates that name resolution is in progress. This process can time out, and the status changes to NEVAC.

Use CA NetMaster NM for TCP/IP to check EE line activation

1. From the command prompt, enter the following panel shortcut:

   /EEXCA
   

   The EE XCA Major Node Summary is displayed. Line status is the second column.

2. Note the host name of any line with a status of PGAIN or NEVAC.
3. From the command prompt, enter the following command:

   CMD NSLOOKUP hostname
   

   The command entry panel is displayed.

4. Press Enter.

   The name lookup executes and returns IPGP12xx messages.

   IPGP1218 indicates that name lookup failed. IPGP1214 indicates a successful lookup.

5. Verify that the specified source VIPA address host name can be resolved from the host name specified in the HOSTNAME VTAM start option or the XCA GROUP definition statement.

Note: The NSLOOKUP result is an indicative test when CA NetMaster NM for TCP/IP's SOCKETS interface uses the same stack as VTAM, and DNR is configured to use the vendor's interface. If SHOW DNR indicates DNR=SOLVE, the NSLOOKUP result is an indicative test when the configuration file setup is the same as the stack's. If CA NetMaster NM for TCP/IP is using a different stack, or the DNR configuration file setup is different to the stack, the NSLOOKUP command does not necessarily return the same result that VTAM is receives.
