Shutting Down a Pathway/XM Environment
The effects of the STOP PATHWAY operation on a TERM object can depend on
whether the STOPMODE register or TRANSMODE register is set in your SCREEN
COBOL program.
If the STOPMODE register is set, the current value of the terminal’s SCREEN COBOL
special register is nonzero. If the TRANSMODE register is set, the terminal is currently
in transaction mode. (You can view the value of the STOPMODE register using the
STATUS command. See the description of the STATUS TERM command in Section 6
for more details.)
Table 7-5
describes the effects of the STOPMODE and TRANSMODE registers on the
STOP PATHWAY command.

ORDERLY ABORT IMMEDIATE
1. Because the TCP was stopped by a Guardian STOP procedure call, the terminals were aborted. Aborting a
TERM object means that transactions are not completed.
2. Indicates a potential Guardian STOP procedure call.
3. Once an external TCP or LINKMON processes notification of an impending PATHMON shutdown, that
TCP or LINKMON process no longer sends data or requests to server classes under the control of the
PATHMON process that is shutting down.
4. If the transaction is protected by the Transaction Management Facility (TMF), TMF aborts the transaction
and resets any data that was changed. If the transaction is not protected by TMF, the effects of the aborted
transaction are unknown.
