Filed under Application Server, howto, Microsoft Windows, Oracle Application Server, Server, Software, System, Tips by on January 18, 2012 at 11:50 am {no comments}

Oracle Application Server is no longer available. The reason is because once “Oracle SOA Suite 10g (10.1.3.1.0)” was released, it contains the same product features and functionality, including some features which are not obtainable without the 10.1.3.1 media. In this tutorial we will see how to install Oracle Application Server 10g R 3(10.1.3.X) on Windows.

Requirements
Windows OS
Oracle Application Server 10.1.3.X

Step 1 Downloading Oracle Application Server 10.1.3.X
Oracle provides 32-bit and 64-bit versions of Oracle Application Server for Windows. The 32-bit version runs on Intel x86, AMD64, and Intel EM64T processors. For additional information, visit OracleMetaLink at http://metalink.oracle.com

I have downloaded the installer files at C:\Downloads\INSTALLABLES\Oracle For 32 bit installer file name would be soa_windows_x86_101310_disk1.zip

I have extracted the same to C:\Downloads\INSTALLABLES\Oracle

Step 2 Starting the installation
Go to extracted folder. In our case it is C:\Downloads\INSTALLABLES\Oracle\soa_windows_x86_101310_disk1\soa_windows_x86_101310_disk1 and double click on setup.exe It will start the Oracle Application Server Universal installer

Step 3 Oracle Application Server 10g 10.1.3.X screen
Enter the installation directory where you want to install Oracle Application Server. In our case I choose D:\product\10.1.3.1\OracleAS_1 Also select Advance Installation mode.

For the Warning please click on yes

Step 4 Select Installation Type screen
In this section choose J2EE server and Web server, as we are going to use only oc4j containers for J2EE and HTTP Server

Step 5 Specify Port Configuration Options screen
In Specify Port Configuration Options screen Select Automatic and click Next

Step 6 Administration Instance Settings screen
In AS administrator settings enter following values:
AS instance Name : techienote
AS Administrator Password : admin_123
OC4J Instance Name : home
Select Configure this as an Administration OC4J instance. This will start EM console as soon as you start the oracle service via OPMN.
Click Next.

Step 7 Cluster Topology Configuration screen

Deselect Configure this instance to be part of an Oracle Application Server cluster topology as this is a simple installation and click on Next

Step 8 Now it will start the installation process

Step 9. Configuration Assistant
At this level installer will configure various service. In case of any failure please see installation logs which are located at C:\Program Files\Oracle\Inventory\logs folder

Step 10 End of Installation
On this screen you will get Oracle Application server EM console URL

Step 11. Access the Oracle Application Server Welcome page to verify that the installation was successful. The URL for the Welcome page is:

http://hostname.domainname:http_port

You can locate the URL for accessing the Welcome Page on the End of Installation Screen text, which is stored in the following file:
ORACLE_HOME\install\readme.txt

The Welcome page provides links to these useful pages:
New features in Oracle Application Server 10g Release 3 (10.1.3)

  • Release Notes
  • Quick Start
  • Demos

That’s it. You are ready with the application server installation. In next section we will see how to deploy sample application in Oracle Application Server.

How to PXE boot Oracle VM Server

Filed under Basic, howto, Linux, PXE, Solaris, System, Ubuntu, Ubuntu by on January 15, 2012 at 3:38 pm {no comments}

Following is the tutorial for installing Oracle VM server through PXE.

Requirement
PXE Server
Oracle VM Server 3.0.2

Step 1 Download & Mount OracleVM-Server.iso

mount -o loop /storage/os/OracleVM-Server-3.0.2.iso cd/

Step 2 Create folder to store oracle vm files.

mkdir -p /tftpboot/images/oraclevm/

Step 3 Copy required files to oraclevm folder under pxe.

cp cd/isolinux/mboot.c32 /tftpboot/images/oraclevm/
cp cd/isolinux/initrd.img /tftpboot/images/oraclevm/
cp cd/isolinux/vmlinuz /tftpboot/images/oraclevm/
cp cd/isolinux/xen.gz /tftpboot/images/oraclevm/

Step 4 append following lines in /tftpboot/pxelinux.cfg/default

LABEL ovs3
kernel images/oraclevm/mboot.c32
append images/oraclevm/xen.gz --- images/oraclevm/vmlinuz --- images/oraclevm/initrd.img

Thats all, now with pxe boot you’ll find option to boot using ovs. Once you boot from ovs pxe, you need to either give path of iso image using nfs store OR give http path where content of cd is copied / cd mounted.
