Title Page | Tools Home Page dynamic saveabend: Dynamic Saveabend File Creation The Dynamic Saveabend File Creation feature allows you to create the saveabend file of a running Java program, without abending (aborting) the Java program, by issuing a signal to the process. This feature allows the Java program to continue after the abend file is created. The time taken to create the abend file, that is, the application pause time is low (measurable in milliseconds).

-d32 -d64 Selects whether the program is to be run in a 32-bit or 64-bit environment. Note: These options are not valid with NonStop Server for Java 5.1, which uses only the 32-bit environment to run Java programs. -Xeprof The -Xeprof option generates profile data for HPjmeter. The -Xeprof option controls profiling of Java applications running on JRE for NonStop operating system for the Java™ 2 Platform and collects method clock and CPU times, method call count, and call graph.
no -Xeprof option is specified, it is equivalent to: -Xeprof:time_on=sigusr2,time_slice=sigusr2 There is no degradation of performance unless you actually start profiling by the specified signal. times=quick|thorough The quick value instructs the profiler to use the hardware Interval Timer register for time measurement. This value results in faster profiling runs, but in extremely rare circumstances, it can produce bad data. This is the default value.
is attributed to its "caller". The default value for this option is enable. Another way of disabling inlining is to collect the profile data while running the VM in interpreted mode (-Xint), although this is usually much slower. The consequences of inlining for the profiling are: ● The obtained profile data does not reflect faithfully all the calls within the Java code as written by the programmer, but rather as it is actually executed by the VM.
%1 Indicates the type of the garbage collection. 1: represents a Scavenge (GC of New Generation only) %2: indicates if this is a parallel scavenge.
%4: Garbage collection invocation.
exceptions. The default units for n are bytes; n must be greater than 1000 bytes. To modify the meaning of n, append either the letter k (or K) to indicate kilobytes, or the letter m (or M) to indicate megabytes. For example, –Xss10240 and –Xss10k are equal. -Xincgc Specifies using the incremental low-pause garbage collector. This option is supported but using it can lead to about a 10% decrease in garbage collection performance.
for Java 5.1application is run as a Pathway server, you can enable this option to alert Pathmon to restart the server after the NonStop Server for Java 5.1 application dies. -XX:GuaranteeFreeHeapSizeAfterGC= Prevents excessive garbage collection (GC) activity in Java applications that have not been tuned well with respect to GC.

Title Page | Tools Home Page jdb: Java Debugger The jdb tool helps you find and fix errors in Java programs. For a complete description of the tool and its use, see the Sun Microsystems documentation for jdb.
Starting a jdb Session There are many ways to start a jdb session. The most frequent way is to have jdb launch a new Java VM with the main class of application to be debugged. You do this by substituting the command jdb for the command java in the command line.
Basic jdb Commands The following is a list of the basic jdb commands. The Java debugger supports other commands, which you can list by using the jdb help command. {help | ?} Displays the list of recognized commands with a brief description. run After starting jdb and setting any necessary breakpoints, you can use this command to start the execution of the debugged application. This command is available only when jdb launches the debugged application (as opposed to attaching to an existing Java VM).
List the threads that are currently running. For each thread, its name and current status are printed, as well as an index that can be used for other commands, for example: 4. (java.lang.Thread)0x1 main running In this example, the thread index is 4, the thread is an instance of java.lang.Thread, the thread name is main, and it is currently running. thread Select a thread to be the current thread. Many jdb commands are based on the setting of the current thread.
Stepping The step command advances execution to the next line whether it is in the current stack frame or a called method. The next command advances execution to the next line in the current stack frame. Exceptions When an exception occurs for which there is not a catch statement anywhere in the throwing thread's call stack, the Java VM normally prints an exception trace and exits. When running under jdb, however, control returns to jdb at the offending throw.
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.
-X option Sets a nonstandard target VM option. Connecting for Remote Debugging i. The Debugger launches the target Java VM. -launch jdb -launch ClassName ii. The Debugger attaches to a previously running Java VM. -attach jdb -attach hostname:portnum For this command, the JVM must already be running as a server at To start the server, use the following command : java -Xnoagent -Xdebug -Djava.
java -Xnoagent -Xdebug -Djava.compiler=NONE \ -Xrunjdwp:transport=dt_socket,\ address=hostname:portnum ClassName Transports A Java Platform Debugger Architecture (JPDA) transport is a form of inter-process communication used by a debugger application and the debuggee. NonStop Server for Java 5.1 provides a socket transport that uses the standard TCP/IP sockets to communicate between debugger and the debuggee. NonStop Server for Java 5.1 defaults to socket transport. NonStop Server for Java 5.
