This is the simple part as we have done the installation
several times in the past. All we do in this step is to download the binaries
as we did in the past article and install the OS. We do take the 64-bit EL 5
versions this time, as I warned you last time, that both the 32 And 64 bit
binaries ask for 64-bit system. Anyway, the Oracle EL installation should be as
simple as anything and we will quickly move on to installing the VMware tools
inside it:
Accept the defaults. (I personally do accept the experimental
feature but you decide for yourself.) Afterwards reboot the vm. After the vm
has rebooted, you can start the VMware Tools via:
vmware-toolbox &
Click on the “synchronize time with host” option.

Installing tightvnc
Normally in the VMware Workstation 6, this is not a
problem as you have your own VNC solution, but should you be installing this on
your physical machine, then it might be handy to use tightvnc.
Get
the tightvnc from Oracle’s site here.
[root@vmmgr tmp]# rpm -ivh
tightvnc-java-1.3.9-3.noarch.rpm
warning:
tightvnc-java-1.3.9-3.noarch.rpm: Header V3 DSA signature: NOKEY, key ID
1e5e0159
Preparing... ########################################### [100%]
1:tightvnc-java ########################################### [100%]
Get VNCViewer.jar (It should be in the
/opt/oc4j/j2ee/home/applications/OVS/webapp1/Class directory)
Sign the jar file like this:
/opt/oc4j/java/jdk1.5.0_11/bin/keytool
-genkey -alias vncviewer -validity 365
/opt/oc4j/java/jdk1.5.0_11/bin/jarsigner vncviewer.jar vncviewer
Check to see if you have the libaio:
[root@vmmgr tmp]# /bin/rpm -q libaio
libaio-0.3.106-3.2
libaio-0.3.106-3.2
Check to see if the following ports are free:
If the command returns nothing, then they are free!
[root@vmmgr tmp]# netstat -na | grep 8888
[root@vmmgr tmp]# netstat -na | grep 8899
Make sure you have OC4J:
[root@vmmgr tmp]# ps -ef|grep oc4j
root 3256 3089 0 16:29 pts/1 00:00:00 grep oc4j
Is OC4J running? (If yes, stop it).
[root@vmmgr tmp]# /sbin/service --help
Usage: service < option > | --status-all | [ service_name [ command | --full-restart ] ]
Note: You can check the status of all services with the
following command:
[root@vmmgr tmp]# /sbin/service --status-all
You can also check the status for that specific process:
/sbin/service -status oc4j
acpid (pid 1756) is running...
anacron (pid 1876) is running...
atd (pid 1886) is running...
auditd (pid 1498) is running...
automount (pid 1737) is running...
Installing Oracle VM Manager
We load the ISO in the VMware workstation and then do the
following:
[root@vmmgr tmp]# cd
[root@vmmgr ~]# mkdir mnt-pt
[root@vmmgr ~]# mount /dev/cdrom mnt-pt
mount: block device /dev/cdrom is write-protected, mounting read-only
Mount the CD on mnt-pt:
[root@vmmgr ~]# cd mnt-pt
Run the installer:
[root@vmmgr mnt-pt]# sh runInstaller.sh
You are prompted with a welcome text:
Welcome to Oracle VM Manager
Please enter the choice: [1|2]
1. Install Oracle VM Manager
2. Uninstall Oracle VM Manager
Note: Select 1, in case you are doing a fresh
installation. In case you want to reinstall the Oracle VM then select 2. Do
ensure that you have cleaned up all the files from the server.
I ran into
this problem:
Failed at "Could not get DeploymentManager".
This is typically the result of an invalid deployer URI format being supplied,
the target server not being in a started state or incorrect authentication
details being supplied.
More information is available by enabling logging -- please see the Oracle
Containers for J2EE Configuration and Administration Guide for details.
Failed
Please see /var/log/ovm-manager/ovm-manager.log for more information.
Deploying application failed.
Please check your environment, and re-run the script:/bin/sh scripts/deployApp.sh
Aborting installation. Please check the environment and rerun runInstaller.sh.
There was no real issue except that I was being a bit
cheeky on the memory. Just make sure that you have about 1500Mb.
I had to reinstall the platform several times and got the
above error.

Oracle Database 10g Express Edition Configuration
-------------------------------------------------
This will configure on-boot properties of Oracle Database 10g Express
Edition. The following questions will determine whether the database should
be starting upon system boot, the ports it will use, and the passwords that
will be used for database accounts. Press <Enter> to accept the defaults.
Ctrl-C will abort.
Specify the HTTP port that will be used for Oracle Application Express [8080]:
We chose the
default tomcat 8080 port, but you can always pick any other port in this case.
Specify a port that will be used for the database listener [1521]:
Specify a password to be used for database accounts. Note that the same
password will be used for SYS and SYSTEM. Oracle recommends the use of
different passwords for each database account. This can be done after
initial configuration:
Confirm the password:
Here we pick an
unbreakable password.
Do you want Oracle Database 10g Express Edition to be started on boot (y/n) [y]:
Select “y”.

issue!

Conclusion
We took a quick virtualization tour of
the Oracle VM Manager installation. In upcoming articles we will look at the VM
templates that Oracle has made available and will also attempt to import the
VM’s from other Xen and VMware servers to Oracle’s hypervisor.
