WMI Static Port configuration

Step one:  Set the DCOM config to use a static port.... Basically, run "dcomcnfg" from command prompt. Navigate the tree to My Computer > DCOM Config > Windows Management and Instrumentation, select properties of that folder. Go to the Endpoints tab Select Properties button for Connection-oriented TCP/IP Use static endpoint, set the port. Step 2:  Configure WMI to use a fixed port http://msdn.microsoft.com/en-us/library/bb219447(v=VS.85).aspx At the command prompt, type  winmgmt -standalonehost Stop the WMI service by typing the command  net stop "Windows Management Instrumentation" Restart the WMI service again in a new service host by typing  net start "Windows Management Instrumentation" Establish a new port number for the WMI service by typing  netsh firewall add portopening TCP 24158 WMIFixedPort Still testing this myself, so not 100% certain it works. Another way, use the Component Services Manager to set the ra...

Optimizing your JVM for Best Performance

The better your JVM performs, the better your installation of Tomcat will perform. It's as simple as that. Getting the most out of your JVM is a matter of configuring its settings to match your real-world performance needs as closely as possible. Update your JVM to the latest version, establish some accurate benchmarks so you have a way of quantifying any changes you make, and then get down to business. Effective Memory Management The main thing to consider when tuning your JVM for Tomcat performance is how to avoid wasting  memory  and draining your server's power to process requests. Certain automatic JVM processes, such as garbage collection and memory reallocation, can chew through memory if they occur more frequently than necessary. You can make sure these processes only occur when they need to by using the JAVA_OPTS -Xmx and -Xms switches to control how JVM handles its heap memory. If your JVM is invoking garbage collection too frequently, use the -Xmx switch to ...

Exploring LXC Networking

Recently I’ve been finding myself in various conversations about  Docker  and  Linux Containers (LXC) . Most of the time the conversations eventually end up with one and the same question and that is whether we should run containers in production. Initially this post had a few paragraphs where I philosophised about readiness of the technology, but I’ve deleted those paragraphs now as the attention dedicated to containers in past year has been nothing short of amazing and more and more companies are running their Infrastructures in the containers or at least big parts of them. I’m sure this trend will continue to high degree in the future, so I’ve now removed these paragraphs and kept the technical content only. One of the (many) things which were not entirely clear to me and to the people I speak with about the topic of containers almost on daily basis is how the networking can be done and configured when using LXC. Hopefully the first blog post on this topic is going...
