Cocoon/tomcat memory usage
I'm trying to further utilize the memory resources of our Linux server for
Cocoon by increasing the StoreJanitor heapsize and Java -Xmx parameters. My
current settings are as follows:
In tomcat4.conf:
JAVACMD="$JAVA_HOME/bin/java -Xmx360m"
In cocoon.xconf (inside the store-janitor element):
<parameter name="freememory" value="20000000"/>
<parameter name="heapsize" value="336000000"/>
Performance has visibly improved as a result. However, actual memory usage
(per top output) seems to peak at 111-112M, no matter what I throw at the
server.
How do I make the JVM and Tomcat/Cocoon utilize more of my machine's memory
(thereby further improving performance hopefully)?
Thanks,
Evan Lenz

Saxon is installed, the error has gone away and the whole thing is faster. The JSP was being called twice because of IE. It doesn't happen with NS/Mozilla etc.
Thanks

It's quite easy - one of the links at

Thanks for that - I did search the archives and found some messages with the same error message as I had but none that I saw had a follow-up. I really did search but until you understand the nature of the problem
better, it is difficult to know what terms to search on. I do apologise for wasting any of your time and thanks again.
I'll try Saxon. I'm not immediately certain how to install it with Cocoon but I'll find out ! The journey is part of the fun.

Chris,
The problem you have is a well-known problem of Cocoon or more precicly of
Xalan. There are many mails in the archives about this topic (e.g.:

If you want to use Saxon have a look at

RE: Changing Xalan XSL (WAS Re: SVG - java socket exception)
Posted by Reinhard Poetz <re...@gmx.net>.
Chris,
The problem you have is a well-known problem of Cocoon or more precicly of
Xalan. There are many mails in the archives about this topic (e.g.:
http://marc.theaimsgroup.com/?l=xml-cocoon-dev&m=101994024218728&w=2).
If you want to use Saxon have a look at
http://outerthought.net/wiki/Wiki.jsp?page=Saxon - it should help (and is
faster than Xalan).

Changing Xalan XSL (WAS Re: SVG - java socket exception)
Posted by Chris Faulkner <ch...@ntlworld.com>.
HI
More on this - a couple of others seem to have similar problems but nobody ever got a reply when they post the error .... makes me think it is a bug. Anyhow, if I change this parameter to false (it is true by default) in
cocoon.xconf
<parameter name="incremental-processing" value="false"/>
I don't get the errors but the JSP is still being called 2 or 3 times so it is much slower and I'd rather leave the incremental-processing parameter at true. How can I change from xalan to another XSL engine ? There
is
a mention of this on the performance tips page but no instructions about how to do it.

SVG - java socket exception
Posted by Chris Faulkner <ch...@ntlworld.com>.
Hello
I am getting on OK with Cocoon. I like it very much. I am using some JSP code as a generator. This creates some XML data which I apply xsl to transform to SVG. This is then serialised with
svgxml and returned to the client. It all works fine. Except that, looking at my logs, very often, the first execution of the JSP returns this to stdout/stderr.
java.lang.RuntimeException: java.net.SocketException: Connection aborted by peer
: socket write error
at org.apache.xalan.transformer.TransformerImpl.run(TransformerImpl.java
:3231)
at java.lang.Thread.run(Thread.java:479)
I can see in the logs that Cocoon automatically seems to fire the same JSP again. It then works on the next shot, I get my SVG displayed in my SVG viewing app and it is just fine. This is
obviously slowing things up though.
Any ideas - I am using Cocoon 2.0.3 on Tomcat 4.0.1, JDK 1.3.1_06 on W2K.
Thanks
Chris

Re: Cocoon/tomcat memory usage
Posted by Christoph Gaffga <cg...@triplemind.com>.
Hi,
you can change some more in the cocoon.xconf. Try the number of cached
objects (MRUMemoryStore, <parameter name="maxobjects" value="10000"/>).
I reach a memory usage of cocoon by around 1,5GB by playing around with
these values.
