Hi,

I m getting heap dump error while deploying my application on AIX5.2.

To know exact memory leakedge and crack in it, i have enabled
verbose:gc option enabled.....It starts showing memory usages on
command prompt.

I want to store all verbose:gc.out to a file.......!

How is it possible?

One more thing.......

while running a script i m getting svmon not found.......wht is
this....how can i run this?

Thanks
Samit

You can just redirect the output of the Java binary to a file, eg:

java -verbose:gc  com.x.Loader 2>&1 | grep 'GC' > /tmp/gc.log

Then, you'll find all lines containing "GC" in the specified file:

cat /tmp/gc.log
[GC 511K->196K(1984K), 0.0048410 secs]
[GC 684K->246K(1984K), 0.0042089 secs]
[GC 728K->364K(1984K), 0.0050664 secs]
[GC 835K->532K(1984K), 0.0036466 secs]
[GC 1010K->675K(1984K), 0.0068208 secs]
[GC 1187K->873K(1984K), 0.0048946 secs]

I don't know AIX very well, but a quick google search showed that svmon
is a tool to monitor memory usage on AIX:

The script you use to start your Java application/server seems to call
it somehow. Maybe it's not installed or you need to specifiy the full
path to it.

Hope that helps
