TS/MP 2.5 System Management Manual

NOTE: For shutting down the PATHMON environment in TS/MP 2.5, PDMCOM or PATHCOM
can be used. However, it is recommended to use PDMCOM (instead of PATHCOM) because it
can communicate with multiple PATHMONs simultaneously. For more information on PDMCOM,
see the TS/MP 2.5 Release Supplement.

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.

Once an external TCP or ACS subsystem processes notifies of an impending PATHMON shutdown, TCP or ACS
subsystem processes no longer sends data or requests to the server classes that are under the control of the PATHMON
process and are 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.
Specifying the ORDERLY Option
The ORDERLY option allows work in progress to complete before shutting down. This command
specifies an orderly shutdown:
= SHUTDOWN2, MODE ORDERLY
The ORDERLY option requires the most time to complete the shutdown operation, because all
transactions in progress are allowed to complete before objects (TCP, TERM, and server objects)
involved in the transaction are stopped. For example, a TERM waiting for I/O to a server class to
complete cannot be stopped until the I/O completes.
The ORDERLY option opens and closes unlinked server processes, permitting the performance of
any epilog processing.
Specifying the ABORT Option
The ABORT option aborts all TERMS for a faster shutdown operation. This command specifies a
shutdown in which terminals are aborted instead of stopped:
= SHUTDOWN2, MODE ABORT
