NAME

gc-analyze - Analyze Garbage Collector (GC) memory dumps

CONTENTS

SYNOPSIS

gc-analyze [OPTION] ... [file]

DESCRIPTION

gc-analyze prints an analysis of a GC memory dump to standard out.

The memory dumps may be created by calling gnu.gcj.util.GCInfo.enumerate(String namePrefix) from java code. A memory dump will be created on an out of memory condition if gnu.gcj.util.GCInfo.setOOMDump(String namePrefix) is called before the out of memory occurs.

Running this program will create two files: TestDump001 and TestDump001.bytes.



        import gnu.gcj.util.*;
        import java.util.*;
       
        public class GCDumpTest
        {
            static public void main(String args[])
            {
                ArrayList<String> l = new ArrayList<String>(1000);
       
                for (int i = 1; i < 1500; i++) {
                    l.add("This is string #" + i);
                }
                GCInfo.enumerate("TestDump");
            }
        }



The memory dump may then be displayed by running:



        gc-analyze -v TestDump001



OPTIONS

--verbose
-v Verbose output.
-p tool-prefix Prefix added to the names of the nm and readelf commands.
-d directory Directory that contains the executable and shared libraries used when the dump was generated.
--help Print a help message, then exit.
--version Print version information, then exit.
