" CANNOT ISSUE TERMSELF WHEN NOT IN SESSION
WITH A HOST-->S0054"
Cause
The terminal operator used a character coded command to log off. The ESS table
logoff record represented by this character coded command was intended for use
in a static session with an AS/400 host, which requires a TERMSELF request.
However, the SLU was not in session with an AS/400 host.
Effect
No TERMSELF request is sent, and no logoff occurs.
Recovery
The terminal should use a character coded logoff command intended for use with
sessions between terminals and Tandem applications,
" GATEWAY LU NOT AVAILABLE--> S0055"
Cause
LUNS was unable to find an available gateway LU.
Effect
No LU-LU session is established.
Recovery
Retry the operation. If the problem persists, have the system operator determine
whether or not there are an adequate number of gateway LUs configured.
