Learn more about JVMs by tuning with JVM Diagnostics

I think we have all been there.  Garbage Collection (GC) for Java Virtual Machines are chewing up your server processing power and once they are done with the server they need to be rebooted.  Instead of a perpetual "throw memory at it" type of solution, take a gander at this post from Oracle.  Were you aware that the JVMD (Java Virtual Machine Diagnostics) tool was part of Oracle Enterprise Manager which is licensed with several other Management Packs?  Is this already in your environment, licensed, and just sitting there gathering dust?  What if you cannot use the tool?  Read the post anyways, and learn about things like "Eden space" or different algorithms to use for your GC!
