jboss-5.1.0.GA on solaris 10 sun4v sparc native libraries missing

[eddepet]

Hello all,

We are running jboss-5.1.0.GA on solaris 10 sun4v sparc SUNW T5240.

Apparently the native libraries for this kind of environment are missing and are even not configurable in the current jboss deployment.

my questions:

1) Which additonal distribution set is nescesary in order to use these native libratries properly? Any other adjustements as well?

2) If I look at the the run.sh script I do not see any support for the 'sunv4' OS. Why is that? Do I need a newer version of Jboss?

3) Currently in our deployment there is no $JBOSS_HOME/bin/META-INF/lib directory. Are we missing some other stuff as well?

Thanks in advance.

Edwin

You do not need the APR native library to run JBoss AS, it runs just fine without it. If you really want to use APR, you can always grab the source code from http://www.jboss.org/jbossweb/downloads/jboss-native-2-0-9.html and compile it for your system.

All you need to run JBoss AS on any system is a Java SE certified JVM.

Hi Peter,

Thanks for your answer.

I was looking for possibilities to increase the performance of this JBoss JVM, and found underneath line in the server.log.
That is why I started looking for the native libs..

13:53:27,136 INFO  [AprLifecycleListener] The Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: /usr/jdk/jdk1.6.0_23/jre/lib/sparc/server:/usr/jdk/jdk1.6.0_23/jre/lib/sparc:/usr/jdk/jdk1.6.0_23/jre/../lib/sparc:/usr/jdk/packages/lib/sparc:/lib:/usr/lib

Question:

Would this help to increase performance, according to you?  Or is it of no use for that purpose?

Thanks in advance,

Edwin

You would have to test it on your system and with your application to see if it would benefit from the APR. If I recall correctly, the best performance boost is serving static static files (CSS, HTML, images, etc.) and little, if any, boost for serving dynamic requests.
