TS/MP 2.5 System Management Manual

In response to this command, the PATHMON process:
• Starts the PATHMON backup process if one is specified.
• Uses the existing configuration file as a basis for creating the operating environment. The
existing configuration file represents the PATHMON configuration at the time the system
stopped (due to shutdown or failure).
• Prompts you, if the PATHMON process name is different from the name stored in the PATHCTL
file, that the PATHMON name is changed in the PATHCTL file.
If you do not want to receive this prompt, you can use the COOL! option as follows:
= START PATHWAY COOL!
NOTE: If you have altered the node independence, owner or security attributes, or you have
increased or decreased system limits, you must specify a cold start operation to restart the
PATHMON environment, as shown in this example:
= START PATHWAY COLD!
This command directs the PATHMON process to overwrite the existing configuration file with the
new information. If you use the COOL start option, the PATHMON process uses the old
configuration file.
Shutting Down a PATHMON Environment
You can shut down your PATHMON environment by stopping all PATHMON-controlled objects
collectively with the SHUTDOWN2 command.
You can choose from these three options: ORDERLY, ABORT, and IMMEDIATE. Each option
provides a different level of shutdown, as described in Table 2 (page 44) 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.
NOTE: This manual provides information specific to commands dealing with objects managed
through the NonStop TS/MP product. PATHCOM commands dealing with requestor objects, such
as TCP, TERM, and PROGRAM objects, which are controlled through the Pathway/iTS product,
are described in Pathway/iTS System Management Manual.
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 “PATHMON
Environment Control Commands” (page 150).)
• 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)” (page 164).)
