9.2.2) Stopping the Device Communication Server

When started in "background" mode (ie. Without the "-i" option), a "Process ID" (PID) file is created at

"$GTS_HOME/logs/template.pid", which contains the process-id of the backgrounded task. This file is used to stop

the server with the command:

/zzz> $GTS_HOME/bin/runserver.pl -s template -kill

On Linux systems, the Perl command "psjava", included with OpenGTS, can be used to display information regarding

which Device Communication Servers are currently running, including the "template" server:

/zzz> $GTS_HOME/bin/psjava

PID Parent L User Java class/jar

------ ------ - -------- -------------------------------------------------------

215( 1) 1 opengts org.apache.catalina.startup.Bootstrap

8115( 1) 1 opengts /usr/local/OpenGTS_1.2.3/build/lib/gtsdmtp.jar

8129( 1) 1 opengts /usr/local/OpenGTS_1.2.3/build/lib/template.jar

This command lists all known running Java processes, with their associated PID (process-id), parent PID, user, and

Java class or jar file which is currently running. The "org.apache.catalina.startup.Bootstrap" process indicates

that Apache Tomcat is running with the indicated PID. "gtsdmtp" and "template" indicate their respective running

Device Communication Servers.

9.3) Runtime XML Configuration File.

The raw socket-based device communication servers (such as the example 'template' server) support the runtime

configuration using the file "dcservers.xml". An example format of the "dcservers.xml" is as follows:

<DCServerConfig

bindAddress=""

backlog=""

portOffset="0"

includeDir="dcservers"

...

</DCServer>

...

</DCServerConfig>

The attributes for the DCServerConfig tag include the following:

bindAddress : This attribute specifies the local IP address or host name to which the server will bind. This is

useful when the local server has more than one IP address, and needs to send UDP packets back to a client

device. If left blank, the server will bind to the default local IP address.

backlog : The maximum queue length for incoming connection indications (a request to connect). If a

connection indication arrives when the queue is full, the connection is refused. If left blank, or is 0 or less, then the

default backlog value will be used. See the class "java.net.ServerSocket" for more information.

portOffset : This value is added to any port specification. Unless otherwise needed for specific system

requirements, this value should remain "0".

includeDir : If the "DCServerConfig" tag contains any "Include" sub-tags, this is the directory that will be

search for the included files.
