Session outages

A session outage is an unexpected abend or termination of the task. Session outages are seen only when an unrecoverable error is detected. The error might be a SNALINK LU0 abend or an error return code from a VTAM® request. A session outage should not occur without an indication of its cause, either on the SNALINK LU0 or the VTAM console. Since SNALINK LU0 abends were already described separately, this topic describes other types of session outages.

For an example of a successful session setup between two SNALINK LU0 applications, see the z/OS Communications Server: IP Configuration Reference.
