Summary: C++ configuration file and setting the JVM options.
Overview Configuring C++ client settings is done using the config.xml file located under cpp\config. The user can change the name and location of the configuration file by defining the Environment variable JVMCONFIG. C++ Configuration File Example

JVM Settings Some options should be predefined in the JvmSettings section:
Name |
Description |
ClassPath |
Adds Java classes to the JVM classpath |
TraceLevel |
Sets the C++ trace levels and output file |
InitialHeapSize |
Intial JVM heap size |
MaximumHeapSize |
Maximum heap size |
SourceClassPath |
Adds Java classes, used for debugging |
Options Any value that is added here is added to the command that creates the JVM. Any key can be added. Debugging To debug from Eclipse, remove the remark from the following lines:
<\!--<add value="-Xdebug" />
<add value="-Xnoagent" />
<add value="-Djava.compiler=NONE" />
<add value="-Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=8001" />-\->
This allows the client to connect from its Java debugger. Connecting to JMX Remove the remark from the following lines for connecting a JMX client:
<\!--<add value="-Dcom.sun.management.jmxremote.port=5003" />
<add value="-Dcom.sun.management.jmxremote.ssl=false" />
<add value="-Dcom.sun.management.jmxremote.authenticate=false" />-\->
