lmstat

The lmstat command interrogates the server's shared memory image to gather a variety of data about the current state of the server. This command is especially useful when you want to determine which server process a client session is on.

SunLink Server software is composed of a set of cooperative processes. When the server is running, enter the following command:

ps -ef | grep lmx

Executing this command generates a display similar to the following:

root 17726 1 0 12:03:36 0:00 lmx.alerter

root 17713 17461 0 12:03:32 0:00 lmx.srv -s 1

root 17722 17874 0 12:03:35 0:00 lmx.srv -s 2

root 17726 1 0 12:03:36 0:01 lmx.dmn

root 17728 1 0 12:03:36 0:01 lmx.browser

root 17744 1 0 12:03:28 0:00 lmx.ctrl

In this example, there are two lmx.srv server processes (17713 and 17722). The server may have nine clients with current sessions.

How does the administrator know to which lmx.srv process a client is connected? Executing the lmstat -c command at the server prompt usually provides the answer. The system displays output similar to the following:

Clients:

BANANA.SERVE~X (nwnum=0, vcnum=0) on 17713

ORANGE (nwnum=0, vcnum=0) on 17713

PEAR (nwnum=0, vcnum=0) on 17722

Notice that each client name has an associated process ID number. This is the process ID of the lmx.srv process that currently is serving that client. The vcnum value specifies whether this is the client computer's first VC or an additional one.

Being able to determine the process ID of the lmx.srv process that is serving a client is particularly useful when using lmstat -w or the Solaris system truss( ) command. Both commands require a process ID as part of their startup arguments. (The -w option is not valid on all operating systems.)
