Specifying the ORDERLY Option
The effects of the SHUTDOWN2 operation on a TERM object can depend on whether
the STOPMODE register or TRANSMODE register is set.
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. For more information, see Section 4, Maintaining Pathway/iTS
Objects.
Table 3-2 describes the effects of the STOPMODE and TRANSMODE registers on the
SHUTDOWN2 command.
Specifying the ORDERLY Option
The ORDERLY option enables work in progress to complete before shutting down.
The following command specifies an orderly shutdown:
= SHUTDOWN2, MODE ORDERLY
Outstanding
work
All outstanding work
(I/O activity) is
completed
For TCPs and server
classes, outstanding
work (I/O activity) is
completed. For
transactions involving
an aborted TERM,
unknown.
4
Unknown
New work Not allowed Not allowed Not allowed
1. Because the TCP was stopped by a Guardian STOP procedure call, the terminals were essentially 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 process) processes notification of an impending PATHMON process
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 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.
