Unable to connect over SNA

There are several possible reasons why CICS® Transaction Gateway is not able to connect to CICS over SNA; for example there might be a problem with an SNA server, or there might be a CICS Transaction Gateway configuration problem. Alternatively, there might be a problem with the connection definition in CICS.

Symptom

CICS Transaction Gateway cannot connect to CICS over SNA.

Probable cause

  • CICS Transaction Gateway has not been configured for SNA correctly, or there is a problem with the configuration.
  • There is a communications problem between the client and the communications server, when using a remote SNA client.
  • There is a problem with the SNA communications server.

Action

  • Check the Client daemon log for errors that indicate there is a configuration problem. Also check the SERVER section of the CICS Transaction Gateway configuration file. For more information see SERVER section of the configuration file.
  • If you are using the Remote API Client (for SNA), check the local SNA error log.
  • If you are using an SNA communications server, check the SNA communications server SNA error log.

For information on configuring the Client daemon to use SNA connections see Configuring an SNA CICS Server definition and Defining SNA connections on CICS Transaction Server for z/OS.
