Oracle VM Manager 2.1.2

Chapter 2. Installing Oracle VM Manager

In the previous chapter, we moved ahead and explored the whole virtualization phenomena and how Oracle's VM platform attempts to fill in the void by using the internal Cloud which we will refer to as IntraCloud environment. An IntraCloud is nothing but our internal data center which is elastic enough to cope with flexible demand within the physical perimeters of our enterprise. In this chapter, we will install the Oracle VM Manager. In particular we will cover the following:

  • Oracle EL U2 installation

  • Installing Oracle VM Manager

  • Upgrading existing Oracle VM Manager

What's new in Oracle VM Manager 2.1.2

Let's quickly go through the latest features of Oracle VM Manager 2.1.2:

  • Server pool wizard: With this easy to use wizard we can create pools in a matter of seconds

  • HA for pools: This is inline with the Continuous Availability of Oracle Cloud Farm, where we can make HA (High Available) pools upon creation

  • P2V and V2V conversions: Convert machines seamlessly...

What's new in Oracle VM Manager 2.1.2

Let's quickly go through the latest features of Oracle VM Manager 2.1.2:

  • Server pool wizard: With this easy to use wizard we can create pools in a matter of seconds

  • HA for pools: This is inline with the Continuous Availability of Oracle Cloud Farm, where we can make HA (High Available) pools upon creation

  • P2V and V2V conversions: Convert machines seamlessly to Oracle format

  • Rate limit of VIF: Set limits to the Virtual Network Interface and customize network traffic per VM

  • Prioritize storage usage with Priority Class option for disk: This way we can define levels of QoS (Quality of Service) per disk, assigning 0 as highest priority and 7 as lowest priority

Clearly Oracle is slowly and gradually working towards the commoditization path of Virtual Infrastructure with Xen, where features such as HA, On-Demand Usage, and Smart Metering make perfect sense for a Cloud Computing model.

What are the hardware requirements?

This section is quite easy to follow. All we need is a machine with the following minimums:

  • Memory: 2 GB RAM

  • CPU: 1.8 Ghz

  • Swap space: 2 GB

  • Hard Disk: 4 GB

For testing purposes, we can also choose to pick up any desktop virtualization software such as Sun's VirtualBox, VMware's Workstation 6.5, VMware's Fusion (for Mac OSX), or any other forms. Eventually we can migrate the VM to our Oracle platform and put it in the HA pool. In practical life, I have seen many production environments using VMM (Virtual Machine Management) Consoles products also as VMs, although it is advisable to use a separate piece of hardware to install VM Management Servers.

Getting the software

Going to the Oracle's VM site (http://www.oracle.com/technologies/virtualization/index.html) will lead us directly to Oracle's e-delivery center (http://edelivery.oracle.com/linux). For more information, go to Oracle's Linux portal: http://www.oracle.com/technology/tech/linux.

All we need to do is to read the EULA carefully and we can go ahead and download the software of our choice. There are Oracle VM templates, Oracle Enterprise Linux Servers, and of course Oracle VM Manager and Oracle VM Servers packages.

Oracle has been working hard and keeping the e-delivery center pretty much up-to-date. The Oracle Enterprise Linux 5 UPDATE 2 has been recently made available and can be downloaded the minute we acknowledge and accept the legal agreement and fill in the details. Here, we can choose to download the 32 bit version of Oracle Enterprise Linux 5 Update 2. It has been built from Open Source Linux source code. We will go ahead and perform installation on the 64 bit platform...

Installing Oracle EL 5 Update 2

Now that we have downloaded the DVD, it's time to install it.

  1. 1. The following screenshot shows the first installation screen:

  2. 2. Point to the DVD ISO image to start the installation as shown in the following screenshot:

  3. 3. Choose the platform and version.

  4. 4. Choose Custom Installation and edit the settings to match the hardware requirements:

  5. 5. For instance, we shall choose 20 GB for the hard disk here:

  6. 6. Now let's start the machine and ensure that the ISO image is selected and the station is connected:

  7. 7. We'll get the following Oracle splash screen. Just press Enter:

  8. 8. We can choose to test the DVD ISO, but let's choose to skip it:

  9. 9. When the installation screen appears, choose Next:

  10. 10. Choose English on both occasions unless of course some other language is preferred:

  11. 11. We need to change the IP address to static, and make sure that it is on the same LAN segment as our Oracle VM Servers:

  12. 12. Now, we need to adjust our regional settings:

  13. 13. Choose...

Final checks before installing Oracle VM Manager

We need to carry out some final checks before the installation process.

Port test

Make sure that ports 8888 and 8899 are free. If, upon entering the following commands, we don't get any response, then it means that these ports are available. 

# netstat -na |grep 8888
# netstat -na |grep 8899

If we do get responses, then we must release these ports and allow them through the firewall by entering the following:

# /usr/bin/system-config-securitylevel

Select Enabled for Security Level and choose customize. In Others add the two ports 8888 and 8899 respectively as follows: 

8888:tcp,8899:tcp

Libaio check

The libaio differs for numerous versions. For our chosen OS we should get the following results: 

# /bin/rpm -q libaio.i386
libaio-0.3.106-3.2

If we don't get the desired result, it's time to install that specific version of the libaio. We can get it from sites such as rpmfind, and others. Enter the following to install the required libaio version.

# rpm...

What comes packaged with the Oracle VM Manager ISO file?

The ISO which we will now use has the following components:

  • Oracle Database 10g Express Edition

  • Oracle VM Manager package

  • Data Collector

  • Server performance information

  • Realtime VM information

  • OVS DataCollector log

  • Oracle Containers for J2EE (OC4J)

  • XML RPC 3.0

Installing Oracle VM Manager

Now that we are done with the preparatory work of installing the OS and have conducted our formal checks on ports and libraries, we can go ahead and install the VM Manager.

Oracle VM Manager installation goes rather fast and we should be done in about 5-15 minutes depending on how well we have installed the Operating System.

  1. 1. Insert the Oracle VM 2.1.2 ISO (if using a desktop virtualization tool) or CD in the CD/DVD ROM drive.

  2. 2. Now, enter the following as the root user to mount it in our Oracle EL OS:

    # mkdir mnt-pt
# mount /dev/cdrom mnt-pt

  3. 3. Here, mnt-pt is the directory where we mount the ISO file. Mounting from a hard drive would go like this:

    # mkdir mnt-pt
# mount -o loop,ro OracleVM-Manager-2.1.2.iso mnt-pt

  4. 4. Next, run the following command from mnt-pt directory:

    # sh runInstaller.sh

  5. 5. The following installation run is self-explanatory:

    [root@vmmgr ~]# cd mnt-pt/
[root@vmmgr mnt-pt]# sh runInstaller.sh
Welcome to Oracle VM Manager 2.1.2

  6. 6. Now enter 1...

Upgrading Oracle VM Manager from 2.1 or 2.1.1 to 2.1.2

Upgrading the Oracle VM Manager from older versions is also an easy procedure:

  1. 1. Again, enter the following as the root user to mount it in our Oracle EL OS:

    # mkdir mnt-pt
# mount /dev/cdrom mnt-pt

  2. 2. Here mnt-pt is the directory where we mount the ISO file.

  3. 3. Mounting from a hard drive would go like this:

    # mkdir mnt-pt
# mount -o loop,ro OracleVM-Manager-2.1.2.iso mnt-pt

  4. 4. Next, running the installer from the mnt-pt directory:

    # sh runInstaller.sh
[root@vmmgr ~]# cd mnt-pt/
[root@vmmgr mnt-pt]# sh runInstaller.sh
Welcome to Oracle VM Manager 2.1.2

  5. 5. This time, enter 3 to upgrade Oracle VM Manager 

    Please enter the choice: [1|2|3]
1. Install Oracle VM Manager
2. Uninstall Oracle VM Manager
3. Upgrade Oracle VM Manager

  6. 6. The upgrade process starts:

    Starting Oracle VM Manager 2.1.2 upgrade ...

  7. 7. Enter y when prompted:

    Are you sure you want to upgrade Oracle VM Manager from version current_version
to new_version ? [y|N]: y

  8. 8. Enter the...

Uninstalling Oracle VM Manager

Uninstallation may be required if something has gone awry in our installation. The following steps will perform a complete uninstall. It is a simple procedure:

  1. 1. Again, enter the following as the root user to mount it in our Oracle EL OS:

    # mkdir mnt-pt
# mount /dev/cdrom mnt-pt

  2. 2. Here mnt-pt is the directory where we mount the ISO file.

  3. 3. Mounting from a hard drive would go like this:

    # mkdir mnt-pt
# mount -o loop,ro OracleVM-Manager-2.1.2.iso mnt-pt

  4. 4. Then run the following:

    # sh runInstaller.sh
[root@vmmgr ~]# cd mnt-pt/
[root@vmmgr mnt-pt]# sh runInstaller.sh
Welcome to Oracle VM Manager 2.1.2

  5. 5. Here enter 2 to uninstall Oracle VM Manager.

    Please enter the choice: [1|2|3]
1. Install Oracle VM Manager
2. Uninstall Oracle VM Manager
3. Upgrade Oracle VM Manager

  6. 6. Enter y to confirm the uninstallation:

    Are you sure you want to uninstall Oracle VM Manager ?[y|N] (Default=N):y

  7. 7. A message stating that the Oracle VM Manager was uninstalled will be displayed...

Logging into WebUI: Oracle VM Manager, Oracle Database, and OC4J homepages

Now that we have successfully installed everything, the Application Server homepage should look like the following:

The Database homepage should look like the following:

And finally our Oracle VM Manager homepage:

Summary

Clearly the installation of Oracle VM Manager 2.1.2 is a breeze. However, it should be noted that taking a snapshot at some critical stages can help us revert back to a particular scenario, in case of a faulty installation where we are forced to perform a reinstall. After all, the purpose of the virtualization ball game is that we don't have to spend endless hours in mundane operational tasks, right?

In the next chapter we will go ahead and install Oracle VM Servers on two of our HP DL 360 Servers.

Oracle VM Manager is a middle tier management front end to Oracle VM, which is really just XEN. I was hoping to find relevant information about Oracle VM itself, well XEN and the differences Oracle VM introduces but there is almost nothing on this essential topic.When the large type, white space, and far too many screen captures are taken into account this 226 page book is really not much more than a pamphlet. There is very little beyond the obvious repetition of the screen prompts and answers. Example: "You will be asked to confirm your action, as shown in the following screen shot:" (1/4 page picture with an OK button) "Your VM will be deleted, as shown in the following screen shot:" (1/4 page screen shot). Nine pages at the end of the book provide an abbreviated overview of xmtop, xm, & virsh command line utilities but you'd find this in the free Xen documentation.Save your money and buy a Xen book.
