8.3.4. Native Components Installation

Procedure 8.1. Install Native Components from RPM

1. Subscribe to the JBOSS EAP5 RHN channel

   1. Using a web browser, navigate to http://access.redhat.com and log in with your credentials.
   2. View the list of all systems, and find the system on which you have installed the Enterprise Platform. Click to view its subscriptions.
   3. Add the JBoss Application Platform or JBoss EWP channel appropriate to your version of Red Hat Enterprise Linux.

2. Install the jboss-eap5-native package

   Log into the application server's host system as the root user.
   Execute the command yum install jboss-eap5-native

3. Install the mod_cluster-jbossas package

   Log into the application server's host system as the root user.
   Execute the command yum install mod_cluster-jbossas

4. Optional: Install the mod_jk-ap20 package

   Follow this step if you need to use mod_jk instead of mod_cluster.
   Log into the application server's host system as the root user.
   Execute the command yum install mod_jk-ap20.

Procedure 8.2. Install Native Components from ZIP archives

1. Download software

   Refer to Appendix A, The Red Hat Customer Portal for file download instructions.
   To install Native Components, choose the Native Components download that corresponds to your operating system and the architecture of your Java Virtual Machine.

2. Unzip components

   Extract the native directory from the zip file into the jboss-eap-5.x directory, so that the native directory is at the same directory level as the jboss-as directory.
   Result:

   The Native Components are installed.

3. Verify installation

   During server start up the server will report the presence of the Native libraries:

   12:12:29,826 INFO [ServerInfo] VM arguments: -Dprogram.name=run.sh -Xms1303m -Xmx1303m
   	   -XX:MaxPermSize=256m -Dorg.jboss.resolver.warning=true -Dsun.rmi.dgc.client.gcInterval=3600000
   	   -Dsun.rmi.dgc.server.gcInterval=3600000 -Dsun.lang.ClassLoader.allowArraySyntax=true
   	   -Djava.protocol.handler.pkgs=org.jboss.handlers.stub -Djava.net.preferIPv4Stack=true
   	   -Djava.library.path=/home/eapuser/jboss-eap-5.2/native/lib64
   	   -Djava.endorsed.dirs=/home/eapuser/jboss-eap-5.2/jboss-as/lib/endorsed
   

   The option -Djava.library.path=/home/eapuser/jboss-eap-5.2/native/lib64 shows that the server is detecting and loading the Native libraries.
