I have been doing some research on this topic and I know that there is quite a bit of information out there. Unfortunately, I usually do not notice articles that recommend JVM tuning setting for servers with X amount of memory. I have an issue with a production tomcat server that is running two applications. One of the applications has an export all records feature AS AN OPTION. The default is export only the 100 rows on the page, but sometimes the Admin needs to go to the site and export all records into excel for their reporting. Now the admin is triggering the export all feature and the server is imploding with out of memory errors for the heap.
This is the current settings: -Xms256m -Xmx1024m -XX:MaxPermSize=384m -XX:PermSize=256m I was wondering what you would recommend for JVM tuning settings on a server that has 8GB or higher of memory? Are there rules that are usually followed in deciding the settings? The server is completely dedicated to the two websites and the database runs on a different server. Thanks, -- James
