Install Xen 3.3 on CentOS 5.2 via http://www.gitco.de/repo/xen3.3.0

It's a review of Sascha's posting to blog mentioned in references
plus test installations PV and HVM DomUs via virt-install with Xen 3.3
Hypervisor running on CentOS 5.2 Dom0 (64-bit).
Download from location above:-

Solaris Nevada DomUs internet working at Xen 3.3 CentOS 5.2 Dom0 (64 bit)

First install Xen 3.3 from mercurial repository on xen-disabled CentOS 5.2 instance,previously installed the most recent version of "git" on the system (git-1.6.0.tar.gz), otherwise "make world" would fail.

# cd /usr/src/
# hg clone http://xenbits.xensource.com/xen-3.3-testing.hg
# cd xen-3.3-testing.hg
# make world
# make install
  

Determine the name of the Xen Linux kernel version that was installed.

# ls /lib/modules
  

There should be a directory for the Xen Linux kernel (e.g., 2.6.18.8-xen)
Generate the module dependency list and map files

# /sbin/depmod 2.6.18.8-xen
  

Create the Xen initial ramdisk image

# /sbin/mkinitrd /boot/initrd-2.6.18.8-xen.img   2.6.18.8-xen 
  

Disable tls

 
# mv /lib64/tls /lib64/tls.disabled
  

Set xend service to start

# /sbin/chkconfig --add xend
# /sbin/chkconfig xend on
   
 

Install bridge-utils:-

# yum install bridge-utils
 

Edit /boot/grub/grub.conf and copy one of the existing boot entries to make the required changes for Xen and reboot into new kernel.

title Xen-3.3 CentOS 5.2 x86_64  (2.6.18.8-xen) 
root (hd1,4) 
kernel /xen-3.3.gz 
module /vmlinuz-2.6.18.8-xen ro root=/dev/VolGroup01/LogVol00 rhgb quiet 
module /initrd-2.6.18.8-xen.img
  

Open following 3 ports on firewall:-


67/UDP Bootstrap Protocol (BOOTP) Server; also used by Dynamic Host Configuration Protocol (DHCP)
68/UDP Bootstrap Protocol (BOOTP) Client; also used by Dynamic Host Configuration Protocol (DHCP)
53/TCP,UDP Domain Name System (DNS)


Allow SSH,HTTPS,HTTP services and proceed with SNV94 DomU install in DHCP mode with pygrub profile:-

name = 'Solaris94PV'
memory = '2048'
disk = [ 'file:/usr/lib/xen-solaris/snv94.iso,6:cdrom,r','phy:/dev/sda10,0,w']
vif = [ 'bridge = eth0' ]
bootloader = '/usr/bin/pygrub'
kernel = '/boot/platform/i86xpv/kernel/amd64/unix'
ramdisk = '/boot/amd64/x86.miniroot'
extra = '/platform/i86xpv/kernel/amd64/unix - nowin -B install_media=cdrom'
  

Load SNV94 DomU with profile:-

name = 'Solaris94PV'
memory = '2048'
disk = ['phy:/dev/sda10,0,w']
vif = [ 'bridge = eth0' ]
 

Bfu DomU to build 96 and reboot:-

Setup Sun Xvnc on DomU and verify Internet access:-

Notice also,that Solaris 10 (05/08) and Free BSD 7 HVM DomUs (32-bit on Intel,64-bit on AMD X2) may be easily installed at Xen 3.3 Linux Dom0(64 bit)

Deployment Seam 2.0.2 Application against Oracle 10gR2 database to Jboss 4.2.3 via NetBeans 6.1 on Solaris Nevada (b96)

Technical exercise bellow is targeting testing Jboss-Seam 2.0.2 SP1 with
NetBeans 6.1 (JDK 6.0) to deploy Brian Leonard's Sample to Jboss 4.2.3
on Solaris Nevada ( build 96) with xVM kernel.
Hibernate has been selected as persistence provider. Oracle 10gR2 database instance has been installed on SNV93 DomU for performance evaluation.

Oracle 10g installation procedure on Solaris Nevada DomU may be viewed if needed


To tune Jboss 4.2.3 instance and make it connects to Oracle Server, perform the following steps on the JBoss Application Server 4.2.3 :
Download the JDBC driver for Oracle 10g Release 2 located at:
http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/index.html
For the Oracle JDBC driver with JDK 1.4 and 1.5, use the ojdbc14.jar file.
Copy the JDBC driver to the JBoss environment by entering the following:
# cp ojdbc14.jar $JBOSS_HOME/server/default/lib
Create a file named $JBOSS_HOME/server/default/deploy/oracle-ds.xml and add the following contents:

<datasources>
  <local-tx-datasource>
    <jndi-name>oracleDS</jndi-name>
    <connection-url>jdbc:oracle:thin:@IP_OR_HOSTNAME_OF _ORACLE_DB_ SERVER:1521:ORACLE_SID
    </connection-url>
    <driver-class>oracle.jdbc.driver.OracleDriver</driver-class>
    <user-name>USERNAME</user-name>
    <password>PASSWORD</password>
    <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleExceptionSorter
    </exception-sorter-class-name>
    <metadata>
   <type-mapping>Oracle9i</type-mapping>
    </metadata>
  </local-tx-datasource>
</datasources>
 

Testing the Oracle Database Connectivity
Test the connectivity between JBoss and Oracle by performing the following steps on the JBoss Application Server:
Create a JSP file named $JBOSS_HOME/server/default/deploy/jmx-console.war/oracleTest.jsp and add the following contents:

<%@page contentType="text/html" import="java.net.*,java.util.*,org.jboss.jmx.adaptor.model.*,
java.io.*,java.sql.*,javax.sql.*,javax.naming.*"%>
<html>
 <head>
  <title>JBoss->Oracle Test </title>
  <link rel="stylesheet" href="style_master.css" type="text/css">
  <meta http-equiv="cache-control" content="no-cache">
 </head>
 <body>
  <%
  InitialContext ctx = new InitialContext();
  DatabaseMetaData dm = null;
  DataSource ds = (DataSource)
  ctx.lookup("java:/oracleDS");
  Connection conn = null;
  Statement stmt = null;
  try {
  conn = ds.getConnection();
  dm =conn.getMetaData();
  out.println("Connected to-> database version "+dm.getDatabaseProductVersion());
  }catch (Exception sqlex) {
  out.println(sqlex.getMessage());
  }finally{
  conn.close();
  }
  %>
 </body>
</html>
  

Start JBoss by entering the following:
# $JBOSS_HOME/bin/run.sh
Verify that the Oracle test page is displayed by opening a browser and navigating to the following URL:
http://localhost:8080/jmx-console/oracleTest.jsp

Follow [1],[2] in new environment.
Add corresponding jars to ejb and web modules ([2]) and
proceed with persistence.xml , keeping Hibernate as persistence provider and selecting datasource as


java:/OracleDS


previously defined for Jboss 4.2.3 Server.

Proceed with tuning web.xml,ejb-jar.xml,faces-config.xml per [1].

Modify code of entity bean User.java and RegistrationActionBean.java ([1])
to instantiate Seam instances at runtime and delete JSF managed bean
as no longer needed.Right click in text area to run "Fix imports" and
select appropriate ones. Embedding seam annotations will require this
fixes to be done.

Annotation @Interceptors({org.jboss.seam.ejb.SeamInterceptor.class})
is required only if ejb-jar.xml has not been modified.
Otherwise , it is not needed

Deploy "Registration Application" to Jboss and run.

Connect to Oracle database from NetBeans 6.1 and perform query against table "users" cumulating inserted records.

Jboss status via NetBeans 6.1 may be viewed here.
