Starting and Stopping a PATHMON Environment

Shutting Down a PATHMON Environment
You can choose from these three options: ORDERLY, ABORT, and IMMEDIATE.
Each option provides a different level of shutdown, as described in Table 2-1 and in the
subsections that follow.
In an environment that includes the NonStop TS/MP product, the PATHMON process
automatically stops SERVER processes under its control, and then the PATHMON
process itself.
In an environment that includes both the NonStop TS/MP product and the
Pathway/iTS product, the PATHMON process automatically stops objects in this order:
TERM objects, TCP objects, SERVER processes under its control, and finally the
PATHMON process itself.
Once you specify a SHUTDOWN2 command:
•
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 Section 11, PATHMON Environment Control Commands.)
•
The PATHMON process logs the start and completion of SHUTDOWN2; it does
not log status messages during shutdown.
(The PATHMON process supports two shutdown commands: SHUTDOWN and
SHUTDOWN2. It is recommended you use the newer, SHUTDOWN2 command for a
faster, more reliable shutdown operation. For compatibility reasons, however, the
SHUTDOWN command is still available. (For more information, see SHUTDOWN
Command (Old) on page 11-20.)
Note. This manual provides information specific to commands dealing with objects managed
through the NonStop TS/MP product. PATHCOM commands dealing with requester objects,
such as TCP, TERM, and PROGRAM objects, which are controlled through the Pathway/iTS
product, are described in
Pathway/iTS System Management Manual .
