In our environment we have many legacy application servers running apache/jserv. There is a web server front end, then a couple of load-balanced java servers on the backside. One of the problems we are faced with is hung or stuck jvms. I have looked at the java process with the ps command, and there are many times when URL(s) do not respond, yet the java looks healthy, at least from the OS

I'm monitoring some CentOS 5 servers running Sun Java. We have set things up so 2048 MB of RAM are available for the base operating system, taking into account the xMx and permgen settings. What we're seeing is the swap space getting used up, and not released. Is this normal behavior? Performance doesn't seem to be affected, however I'm a bit concerned that the swap file is

i chose to install tomcat during the OS install as well as java....however, since I needed to use a different jvm, i used the method described in http://wiki.centos.org/HowTos/JavaOnCentOS for Sun jdk 1.5.0_13 and it worked fine as I can tell, as using the alternatives --config java command, i see both 1.4.2 and 1.5.0 versions and choosing the 1.5.0 version yields the right version when doing a

Hi, I have been steadily migrating machines, about 50-70 of them to Centos 4.3, mostly using Opteron Dual Core/ Tyan boxes of Supermicro origin. They perform apache, mysql, tomcat and qmail work, depending where they exist The main reason from the programmer side (i'm a sysadmin/ engineer) is the larger "heap size" to satisfy some of the needs. Since Java/Tomcat applications can

So whats good practice for installing Java/JDK and Tomcat for EL6 these days? The base repository included Tomcat6.6 is built with GCJ which I'd rather avoid. I'm fine with using OpenJDK ...

I've used Fedora for years, but am getting tired of the obsolescence that keeps happening. I'm also very excited about having an integrated Java that I can use for actual server deployments. I
