CORBA 2.6.1 Administration Guide

commands cause PATHMON to stop the processes. The thaw and start commands restart the processes.
Monitoring Status
The PATHMON process maintains information about process configurations, process status, and operations statistics. The following table lists
the PATHCOM commands and their effects:
PATHCOM Commands
PATHCOM Commands Effect
INFO Returns current configuration information
STATUS Returns the current state of a process, for example: RUNNING, STOPPED, or SUSPENDED
STATS Returns process usage statistics
Most status and statistics information collected by these commands is collected by the Pathsend API and the LINKMON process.
The Pathsend API provides procedure calls that are used by clients to access TS/MP server processes. The LINKMON process is a link
manager that provides link management functions for Pathsend requests.
Note:
Statistics information is not available for the Comm Server and the LSD because they are not accessed by the
Pathsend API or the LINKMON process, which collect the information. Status and statistics information is available,
however, for the Naming Server and Event Server and for all TS/MP application server processes.
Displaying Configuration Information
Use the INFO command to display configuration information. You can display configuration information about your overall TS/MP environment,
about the PATHMON process, or about specific server pools in the environment by using the following commands:
INFO PATHWAY
INFO PATHMON
INFO SERVER
INFO PATHWAY Command
To display global parameters for the overall TS/MP environment, type the following:
= INFO PATHWAY
The example below shows the information displayed when you execute the INFO PATHWAY command for the TS/MP environment:
INFO PATHWAY Display
=info pathway

This output shows current values of the global TS/MP environment variables. These variables are set by the nsdstart shell script, or by using
the
SET PATHWAY command to enter the values manually.
Note: Several parameters are not relevant for NonStop CORBA applications, and should be set to zero when you
configure the NonStop CORBA system. These parameters include MAXEXTERNALTCPS, MAXTCPS, and
MAXTERMS.
From TS/MP 2.3 onwards the default Pathway security setting is 0 (zero). The Pathway security setting can
be changed to the required value using
SET PATHWAY SECURITY in the nsdstart script.
Executing the INFO command lets you determine whether current global limits are being reached, because the display shows maximum limits on
the left and actual current totals on the right. In the above example, the configuration allows a maximum of 40 server processes to be running at
any given time. The current total is 8 server processes running. To see complete syntax and descriptions for all global parameters, refer to the
NonStop TS/MP System Management Manual.
INFO PATHMON Command
To display information about parameters set for the PATHMON process, type the following PATHCOM command:
