Re: DOM memory management

My Windows VM gives the following help:

C:\>java -X
    -Xmixed           mixed mode execution (default)
    -Xint             interpreted mode execution only
    -Xbootclasspath:<directories and zip/jar files separated by ;>
                      set search path for bootstrap classes and resources
    -Xbootclasspath/a:<directories and zip/jar files separated by ;>
                      append to end of bootstrap class path
    -Xbootclasspath/p:<directories and zip/jar files separated by ;>
                      prepend in front of bootstrap class path
    -Xnoclassgc       disable class garbage collection
    -Xincgc           enable incremental garbage collection
    -Xloggc:<file>    log GC status to a file with time stamps
    -Xbatch           disable background compilation
    -Xms<size>        set initial Java heap size
<--------------------------------
    -Xmx<size>        set maximum Java heap size
    -Xss<size>        set java thread stack size
    -Xprof            output cpu profiling data
    -Xrunhprof[:help]|[:<option>=<value>, ...]
                      perform JVMPI heap, cpu, or monitor profiling
    -Xdebug           enable remote debugging
    -Xfuture          enable strictest checks, anticipating future default
    -Xrs              reduce use of OS signals by Java/VM (see
documentation)
    -Xcheck:jni       perform additional checks for JNI functions

The -X options are non-standard and subject to change without notice.

How do you specify the -mx option while starting the JVM?

DOM is a memory intensive parser.  You could change the heap size for your
VM
by providing -mx parameter when you start your VM.  Alternately,  you could
JDOM which needs much less memory than DOM.  It uses the flyweight pattern
for
the memory management.  I am not sure of DOM4J.

Subject: DOM memory management


I'm doing a conversion program which convert a database to a xml file.  It
is relatively a small database.  However, during conversion, i received a
"out of memory" message from my java program.

Has any one face this problem before?  can anyway advise me on the memory
management of DOM???
