Chapter 5: Oracle VM Manager Sizing, Installation, Updates and the Oracle VM Manager CLI

Oracle VM Manager is a bare bones stand-alone management solution for Oracle VM servers, Oracle VM server pools and Oracle VM guests. Oracle VM Manager is a light weight private source cluster ready Oracle Application Development Framework 10g (ADF) application that installs on Enterprise Linux. Oracle VM Manager also has a command line interface that allows Oracle VM Manager administrative tasks to be perform from the command line or executed using scripts.

Oracle VM Manager is supported on a physical or virtual Enterprise Linux operating system. Oracle VM Manager is a great candidate for virtualization on Oracle VM or Oracle VM VirtualBox. Virtualizing Oracle VM saves on hardware costs and improves application flexibility while reducing data center space.

Note: Oracle VM Manager is not supported and should not be installed in Oracle VM server's dom0.

List 1 shows the supported Enterprise Linux operating systems and virtualization platforms for Oracle VM Manager.

Oracle Enterprise Linux 4 update 5 or later
Red Hat Enterprise Linux 4 or later

Oracle VM VirtualBox

Oracle VM Manager is distributed in three formats; a) as an ISO file that installs on Enterprise Linux b) as a pre-packaged Oracle VM template (with the CLI) and c) as the Oracle VM Management Pack plug-in.

Oracle VM Manager is considered the leading edge development platform for the Oracle VM Management Pack, which is an Oracle Enterprise Manager plug-in. Oracle VM Manager 2.1.2 was ported to Oracle Enterprise Manager 10.2.0.5 and Oracle VM Manager 2.2 was ported to Oracle Enterprise Manager 11g R1. Expect at least a six month lag for Oracle to port a new Oracle VM Manager release to the Oracle VM Management Pack.

Note: The Oracle VM Management Pack is licensed software; Oracle VM Server and Oracle VM Manager are not licensed software.

Figure 1 highlights the Oracle VM Manager 2.2 user interface.

The next chart shows the matrix of supported Oracle VM Manager and Oracle VM server combinations.

   OVM 2.1.0  2.1.1  2.1.2 2.1.5  2.2.0
OVS --------+------+------+-----+------
2.1.0     O |    O |   O  |  O  |  O
2.1.1     X |    O |   O  |  O  |  O
2.1.2     X |    X |   O  |  O  |  O
2.1.5     X |    X |   X  |  O  |  O
2.2.0     X |    X |   X  |  X  |  O
2.2.1     X |    X |   X  |  X  |  O

Note: Oracle VM Manager can manage many Oracle VM server pools, e.g. Oracle VM Manager 2.2 can manage one pool of Oracle VM 2.1.x servers, another pool of Oracle VM 2.2 servers, and many more server pools; But within the same server pool, all the servers must have the same version of Oracle VM server and the Oracle VM agent. Mixing Oracle VM 2.1.x and 2.2.x servers in the same pool is not supported.

Oracle VM Manager Resource Requirements

Oracle's recommends 2 GB of memory and one 1.83 GHz CPU for VM Manager. Oracle's minimum resource recommendations for VM Manager is appropriate for a small Oracle VM pool with a hand full of Oracle VM servers without the Command Line Interface.

Oracle VM Manager resource requirements can be quickly tested with Oracle VM Manager user interface (UI) page response times. For example, if the Oracle VM Manager user interface is painfully slow or if you experience page timeouts adding memory and CPUs will speed up the user interface and eliminate page timeouts.

Tip: Oracle VM Manager on VMware is performance challenged and will need substantially more CPU and memory than the minimum recommendations. Oracle VM Manager is a great fit running on a virtualized Enterprise Linux operating system on an Oracle VM server.

Table 1 lists Oracle's recommended minimum resource requirements for Oracle VM Manager 2.x.

Description	Minimum Resources
Memory	2 GB
Processor	1 1.83 GHz CPU
Swap Space	2 GB
Hard Disk Space	4 GB

The memory and CPU requirements for Oracle VM Manager 2.x scales up as the number of Oracle VM pool members grow.

Table 2 shows the recommended CPU and memory allocation for three different Oracle VM Manager deployments.

Number of Oracle VM Server Pool Members	Memory	CPU	Swap
< 10	2 GB	1 1.83 GHz	2 GB
> 10	4 GB	2 2 GHz	8 GB
> 32	8 GB	4 2 GHz	8 GB

Supporting Large Oracle VM Manager User Communities

If Oracle VM Manager will be supporting over 10 users ensure that the OVM Manager host has at least 2.5G of RAM with the following oc4j script modifications.

On the OVM Manager host, edit the “/opt/oc4j/bin/oc4j” file and change this line:

OC4J_JVM_ARGS="-XX:PermSize=256m -XX:MaxPermSize=512m"

to:

OC4J_JVM_ARGS="-XX:PermSize=512m -XX:MaxPermSize=1024m -Xms2048m -Xmx2048m"

Next, restart the OC4J service on the Oracle VM Manager hosts by typing "service oc4j restart".

Oracle VM Manager Installation Prerequisites

libaio RPM Package

Oracle VM Manager uses the Oracle Database 10g Express Edition as the default data repository. The Oracle Database 10g Express Edition requires the libaio package release 0.3.96 or above.

To validate if your Enterprise Linux system has the libaio 0.3.96 or above package, as root “type rpm -q libaio” as shown in the next example.

# rpm -q libaio

libaio-0.3.106-3.2

If you get no result from typing “rpm -q libaio” you will need to install the libaio package. To install libaio from the Oracle Unbreakable Linux network type “up2date -i libaio” as shown in the next example.

# up2date -i libaio

Name Resolution

Before you install Oracle VM Manager ensure that the Oracle VM Manager server's host name is properly entered in the /etc/hosts file. The host name, i.e. fully qualified domain name (FQDN) must be associated with the public IP address.

The next example shows an “improper” Enterprise Linux /etc/hosts file entry.

127.0.0.1 servername.com servername localhost.localdomain localhost

192.168.4.8 servername.com servername

The next example shows the proper syntax for an Enterprise Linux /etc/hosts file entry.

127.0.0.1 localhost.localdomain localhost

192.168.4.8 servername.com servername

Host Firewall & Port Test

Oracle VM Manager will reserve tcp ports 8888, 8899 and 4443 for the Oracle VM Manager application. Before installing Oracle VM Manager on the Oracle VM Manager host, check that ports 8888 and 8899 are free. As root type “netstat -na |grep 8888” and then type “netstat -na |grep 8899”. If you do not get a response by typing “netstat -na |grep 8888” and “netstat -na |grep 8899” the ports are free. If you do get a response the ports must be released before you can install Oracle VM Manager.

If your Enterprise Linux host uses iptables you will need to allow tcp traffic on ports 8888, 8899 and 4443 to allow access to the Oracle VM Manager portal.

To allow tcp traffic on ports 8888, 8899 and 4443 on the Oracle VM Manager host, as root or with sudo type the following three commands:

# system-config-securitylevel-tui -q -p 8888

# system-config-securitylevel-tui -q -p 8899

# system-config-securitylevel-tui -q -p 4443

SMTP Server

Oracle VM Manager has several user notification features that require the use of an SMTP server. During the Oracle VM Manager installation you will be asked to a) enter the SMTP server IP address or fully qualified domain name and b) the SMTP port and c) a valid email address and password for the Oracle VM Manager admin account.

Entering the SMTP details during the installation is optional and can be configured after the installation by using the “update_email.sh” script on the Oracle VM Manager host or by editing the values in Oracle VM Manager repository database table ovs_sys_value under the OVS schema.

Oracle VM Manager Guest Console

The semi integrated Oracle VM Manager guest console requires the Oracle VM Manager host to have the TightVNC package installed. The TightVNC package allows non-Linux users, i.e.Windows or MAC clients to use the TightVNC guest console.

The TightVNC package can be downloaded from: http://oss.oracle.com/oraclevm/manager/RPMS/

The next example shows how to download and install the TightVNC package on the Oracle VM Manager host as root. The TightVNC package can be downloaded and installed in any directory, i.e. /tmp on the Enterprise Linux host.

# wget http://oss.oracle.com/oraclevm/manager/RPMS/tightvnc-java-1.3.9-3.noarch.rpm

# rpm -ivh tightvnc-java-version.noarch.rpm

Note: If you use Firefox on Linux to access the Oracle VM Manager user interface and would like to use the TightVNC guest console you will also need to install the Oracle VM Manager console plug in (ovm-console) on your Linux workstation. The ovm-console package is available at http://oss.oracle.com/oraclevm/manager/RPMS/.

Required Installation Passwords and Password Complexity Requirements

During the Oracle VM Manager Installation you will be prompted for a total of five required passwords.

List 2 shows the five required passwords.

The password for the Oracle XE SYS and SYSTEM accounts.
The password for the Oracle VM Manager OVS database schema.
The password for the OC4J oc4jadmin account.
The password for the Web Service keystore file.
The password for the admin account.

List 3 shows the password complexity requirements for the required passwords.

The password must begin with an uppercase or lowercase letter.
The password may include the following characters:
- Numbers (such as 1, 2, 3, and so on), letters (from a to z, A to Z), and underscores (_).
Examples of valid passwords: Password01, Password_123, password.

Tip: Select and write down all the passwords before you start the installation. Unfortunately you may not be able to use the same password for all four services because the Web Service has a slightly different password policy.

Oracle VM Manager Installation

An Oracle VM Manager installation takes approximately 5-15 minutes depending on the performance of the Oracle VM Manager host.

During the Oracle VM Manager installation, you are required to set the following ports. Please note that the installer program will provide defaults.

The Oracle XE HTTP port. The default port number is 8080.
The Oracle XE listening port. The default port number is 1521.

1. Download the Oracle VM Manager ISO file from the Oracle eDelivery Linux portal.

2. Log in to the Oracle VM Manager host as root.

3. Copy the Oracle VM Manager ISO file to a directory on the Oracle VM Manager host, i.e. to the /tmp directory.

4. Create a directory to mount the ISO file, i.e. mkdir -p /tmp/mount-point.

5. Mount the ISO file by typing “mount -o loop,ro OracleVM-Manager-version.iso mount-point”

6. Change into the directory where the ISO file is mounted, i.e. “cd /tmp/mount-point.

Updating Oracle VM Manager using the Installation Media

Unlike Oracle VM Server, which has multiple update options Oracle VM Manager is updated by downloading the media from Oracle’s eDelivery portal and executing an installation script. Oracle VM media is freely downloadable from Oracle’s eDelivery system at http://edelivery.oracle.com/linux.

Updating Oracle VM Manager is accomplished by running the Oracle VM Manager installation program on the Oracle VM Manager host and to select the upgrade installation option. The Oracle VM Manager installation program will ask for the passwords for the existing Oracle VM Manager OVS database account and the oc4jadmin account. The Oracle VM Manager OVS database account and the oc4jadmin account passwords are selected during the Oracle VM Manager installation process. The account passwords for the Oracle VM Manager OVS database account and the oc4jadmin account can be managed from their respected web portals.

Note: The Oracle Database Express Edition portal and the Application Server Control portal are installed by default with the Oracle VM Manager portal. The Oracle VM Manager Template does not enclude the Oracle Database Express Edition portal and the Application Server Control portal.

OVS Database and oc4jadmin Accounts and Passwords

The OVS account can be maintained from the Oracle Database Express Edition portal. The Oracle Database Express Edition portal is a part of the Oracle VM Manager install and can be accessed locally by entering http://127.0.0.1:8080/apex or remotely by entering the ip address or the FQDN followed by :8080/apex, i.e. http://OracleVM_Manager_fqdn:8080/apex in a web browser.

The next Figure shows the Oracle Database Express Edition portal login page.

The Application Server Control portal is a part of the Oracle VM Manager install. The oc4jadmin account can be maintained from the Application Server Control portal. The Application Server Control portal can only be accessed locally from the Oracle VM server console by entering http://127.0.0.1:8888/em in a local web browser.

The next Figure shows the Application Server Control portal login page.

Updating Oracle VM Manager

The following section will review each of the steps of a successful Oracle VM Manager upgrade.

The update process requires you to select the upgrade option from the install prompt as well as enter the passwords for the Oracle VM Manager OVS database account and the Oracle VM Manager oc4jadmin account.

Step 1 is to download the ISO image from http://edelivery.oracle.com/linux.

Once the ISO image is downloaded and placed on the Oracle VM Manager host or made available from a network share then it should be mounted as root user.

The following example shows how to mount the Oracle VM Manager ISO image from the Oracle VM Manager server console as root user.

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

# cd mnt

# ls

EULA LICENSE readme.txt runInstaller.sh scripts source TRANS.TBL

Step 2 is to execute the runInstaller.sh script within the Oracle VM Manager root directory from the Oracle VM Manager server console as root.

The following example shows how to execute the runInstaller.sh from the Oracle VM Manager server console as root user.

# sh runInstaller.sh

Step 3 is to select the Upgrade option (number 3) from the install prompt. The next example shows the installation choice prompt.

Please enter the choice: [1|2|3]

1. Install Oracle VM Manager

2. Uninstall Oracle VM Manager

3. Upgrade Oracle VM Manager

Step 4 asks if you would like to proceed or cancel the upgrade. You can enter y to proceed or n to cancel the upgrade. The following example shows the upgrade acceptance prompt.

Are you sure you want to upgrade Oracle VM Manager from version 2.1.1 to 2.1.2 ? [y|N] y

Step 5 is to enter the OVS password. The following example shows the OVS installation password prompt.

Please enter the password for database account 'OVS':

Step 6 is to enter the oc4jadmin password. The following example shows the oc4jadmin installation password prompt.

Please enter the password for account 'oc4jadmin':

Step 7 is to enter yes or no to backup the Oracle VM Manager database. This step is optional, i.e. entering no will not abort the upgrade. The following example shows the Oracle VM Manager database backup prompt.

Would you like to back up the Oracle VM Manager database?

Now back up the Oracle VM Manager database to /usr/lib/oracle/xe/app/oracle/product/10.2.0/server/dump-2008-10-06-05-24-25-PM.dmp

A successful upgrade will exit with the following informational warnings.

To access the Oracle VM Manager help page go to:

http://ovm01.com:8888/help/help

Step 8 is to validate the Oracle VM Manager version number from the Oracle VM Manager home page. The Oracle VM home page URL can be accessed locally via http://127.0.0.1:8888/OVS or from a remote web browser via http://ip_address_of_host:8888/OVS or http://fqdn:8888/OVS. From the Oracle VM Manager home page you can validate the version number from the footer of the home page.

Oracle VM Manager Database Backup and Restoration

Oracle VM Manager Database Backup

The Oracle VM Manager batabase can be backed up using the backup.sh script. Before you backup the Oracle VM Manager database, access Oracle VM Manager and ensure that the status of all of the Oracle VM servers is "Running". You will need the following details for the backup procedure a) the password for database account 'OVS', which was assigned during the Oracle VM Manager install, b) the path for dump file, i.e. /tmp/ovs.dmp and c) the path for log file, i.e. /tmp/ovs.log. We will conclude Step 1 with a complete Oracle VM Manager database restore.

The following example shows how to execute the “/opt/ovs-manager-2.2/bin/backup.sh” script from the Oracle VM Manager host as root user.

# sh /opt/ovs-manager-2.2/bin/backup.sh
