" SESSION NOT BOUND -GUARDIAN 90 USESEGMENT ERROR--> S0046 "
Cause
During processing of the failing command, an error was returned when LUNS
issued a USESEGMENT call to place a previously allocated extended-memory
segment into use.
Effect
The failing command is ignored and the terminal’s keyboard is reset to allow the
entry of another command. Additional information can be found in EMS event
message 81 (LUNS error code 2311).
Recovery
Check EMS event message 81 for LUNS error code 2311 and consult its description
in the Operator Messages Manual for the appropriate recovery action. Problem
isolation might require that you consult your Tandem representative.
" INVALID ESS ENTRY FOR A CHARACTER CODED LOGON -> S0049 "
Cause
The failing command matches the command name of an ESSCMD record in the
terminal’s ESS table, but the record’s CMDTYPE is INITSELF-RECEIVED. Such a
record can be referenced only by an SNA INIT-SELF request from a terminal—not
by a character-coded SNA request.
Effect
The failing command is ignored and the terminal’s keyboard is reset to allow the
entry of another command.
Recovery
Check that the ESSCMD record in the terminal’s ESS table whose command name
matches the failing command is defined as you intended. If necessary, see
“Finding an Assigned ESS Table” earlier in this appendix.
