NonStop Server for Java 4.2 Tools Reference

connector.
-launch
Launches the debugged application immediately upon startup of jdb. This option
removes the need for using the run command. The debugged application is launched
and then stopped just before the initial application class is loaded. At that point you
can set any necessary breakpoints and use the cont to continue execution.
-connect connector-name:name1=value1,...
Connects to the target VM through a named connector that uses the listed argument
values.
-dbgtrace [flags]
Prints information for debugging jdb.
-Joption
Pass option to the Java virtual machine, where option is one of the options
described on the reference page for the java application launcher. For example,
-J-Xms48m sets the startup memory to 48 megabytes.
Other options are supported for alternate mechanisms for connecting the debugger and
the Java VM it is to debug. The Java Platform Debugger Architecture has additional
documentation on these connection alternatives.
Deviations from Standard Java
-tclient
Runs the application in the Java HotSpot client VM.
Note: The -tclient option is not valid with NonStop Server for
Java 4.
-tserv
Runs the application in the Java HotSpot server VM.
Note: -tserv is the default option for NonStop Server for Java 4;
therefore, specifying -tserv is optional.
Options Forwarded to the Process Being Debugged
-v -verbose[:class|gc|nji]
Turns on verbose mode.
-D name=value
Sets a system property.
-classpath directory1 [:directory2]...
Lists directories in which to look for classes.
