Should this tool work with the IBM JDK running on the iSeries V5R4 with the 64-bit JVM? We have WebSphere Application Server 6.0.2.19 installed and this tool cannot read the native_stdout.log created by enabling the verbose gc option.

Hello,
I have the same problem. I was unsuccessful in finding an iSeries WebSphere JVM verbosegc analysis tool. I decided to write one, its a start. Your feedback will be valuable!
Here is the URL: https://sourceforge.net/projects/gcanalysis/

I've not been able to get PMAT or the tool listed at sourceforge.net to work properly.
I'm having issues getting PMAT to recognize my native_stdout.log as a verbose gc log.
{from i5/OS V5R4 running WAS 6.1 Express with 1.5 JVM}
Using this string to initiate PMAT:
java -Xmx500m -jar ga36.jar
When I try to open native_stdout.log, it tells me "Cannot find any verbose garbage collection log"
native_stdout.log contains:
GC 20: starting collection, reason stop the world collection.
GC 20: starting collection, reason stop the world collection.
GC 19: live objects 2045671; collected objects 526101; collected(KB) 149995.
GC 19: queued for finalization 0; total soft references 4498; cleared soft references 0.
GC 19: current heap(KB) 584228; current threshold(KB) 98304.
GC 19: collect (milliseconds) 221811.
GC 19: current cycle allocation(KB) 223; previous cycle allocation(KB) 309901.
GC 19: total weak references 11167; cleared weak references 0.
What am I doing wrong?
