Respond to VTAM Communication Problems

If you experience a communication problem when using VTAM with the communications server, follow these guidelines:

If VTAM fails on a system, restart VTAM as soon as possible. As soon as the VTAM resources are activated CA-L-Serv reestablishes communications.
If a VTAM route fails but VTAM remains active, reactivate that route using the ACTIVATE command.
Issue D NET,ID= commands on both systems to verify that your ACB VTAM definitions (ACB and CDRSC) are active.
