Being the eternal optimist, I would like to ask if anyone know how to do this for Tomcat 4.x.... there is no "Configure Tomcat" on the Windows menu?
It's a while since I ran Tomcat under Windows, but I believe you can set the JAVA_OPTS environment variable by editing the tomcat_home/bin/catalina.bat e.g:
set JAVA_OPTS=-Xms128m -Xmx512m

I figured it out for Windows server. Go to Start->Programs->Apache Tomcat 5.0->Configure Tomcat. This will open up a dialog box to change settings. Click the middle tab, Java VM. There is a text area to add Java Options. After the last entry, -Xrs, add -Xms<value> -Xmx<value>, where these are the minimum size and maximum size of memory usage for the Java virtual machine (JVM). Click Apply or OK, and restart the Tomcat service.
One of the reasons I didn't think of this originally is that Apache Tomcat 5.0 was missing from Start-Programs on my development server. I like to test in development before testing in production. Once I figured this out I reinstalled Tomcat on my development server, which placed Apache Tomcat 5.0 in Start->Programs. From there I was able to set and test the memory settings for the JVM in development, and eventually place these into production. The XSP that hits the Oracle database now flies. I can gather a 10947 record, 9.5 megabyte data stream quickly. It's an entirely new web site. It really performs well. I can't believe the improvement in performance I received with the new memory settings.
The increased performance isn't only with Cocoon. Performance of our ArcIMS applications has increased considerably.
Once again, thanks to all who provided assistance.

I'm desperately seeking a real working solution to memory management in Java-Tomcat-Cocoon in Windows. I continue to run into low memory errors. I researched the Cocoon wiki, Java web sites and Tomcat web sites, but none of the solutions appears to work. I can't get Cocoon to use more than the default 64 MB of memory allotted by the JVM. I had initially gotten Cocoon to free up 50% of the available memory, so I had 64 Meg in use, with around 30 Meg free. This initially help me with an XSP issue, but now when I check Cocoon status I see that memory is getting low again, sometimes the status page will show just over 1 meg of free memory. My XSP no longer works.
Our configuration:
2.4 GHz Xeon Processor Compaq server 2.5 Gigabytes RAM Windows 2000 (5.00.2195 Service Pack 4) J2SDK 1.4.2_03 Apache 2.0.49 Tomcat 5.0.18 Cocoon 2.1.5.1
I trying to sell Cocoon as a tool to help with a project at work. If I can't get consistent results with the XSP, management will not go with Cocoon and will turn to another solution. This will be a major set back for greater use of Cocoon in our agency. I'm also trying to sell other agencies in Wisconsin on the benefits of Cocoon, but this recent set back will only make my efforts more difficult.
Any assistance I can get is greatly appreciated. I would like to see Cocoon used for tasks other than a simple web publishing system. But the way it looks right now, that will be a hard sell in my agency and to other State of Wisconsin government agencies.
