Pathway/iTS Objects and the SHUTDOWN2
Command
Pathway/iTS Objects and the SHUTDOWN2
Command
You can shut down the whole PATHMON environment by stopping all
PATHMON-controlled objects collectively with the SHUTDOWN2 command.
The PATHMON process automatically stops objects in this order: TERM objects, TCP
objects, SERVER objects under its control, and finally the PATHMON process itself.
When you specify a SHUTDOWN2 command, these actions occur:
•
All TCP objects begin shutdown (shutting down TERM objects and then
themselves) in parallel.
•
New work is disallowed. For example, all ADD, ALTER, and DELETE commands
are invalid. (For a complete list of commands that are disabled during shutdown,
see the TS/MP System Management Manual.)
•
The PATHMON process logs the start and completion of SHUTDOWN2; it does
not log status messages during shutdown.
Three options—ORDERLY, ABORT, and IMMEDIATE—provide different levels of
shutdown, as described in Table 3-1 and the subsections that follow.
Note. This subsection describes the effect of the SHUTDOWN2 command and options on
Pathway/iTS objects controlled by the PATHMON process. For a comprehensive discussion of
shutting down a PATHMON environment in addition to the syntax of the SHUTDOWN2
command, see the TS/MP System Management Manual.
The SHUTDOWN2 command replaces the SHUTDOWN command. It is recommended that
you use the SHUTDOWN2 command for a faster, more reliable means of stopping your
PATHMON environment. The SHUTDOWN command, described in the TS/MP System
Management Manual, is still available to maintain backward compatibility.
Note. Because Pathway/iTS router processes are not part of the PATHMON environment, the
SHUTDOWN2 command has no effect on the router processes. You must stop these
processes by using TACL.
