VMware: Howto setup vCenter Server 2.5 on Linux connecting to Oracle XE 10g Release 2 – Part I
Still processing all the info from VMworld Europe 2009 I remembered something about vCenter Server that it was available on Linux. I searched on the VMware site and found the beta version. I downloaded the virtual appliance and the installation guide. I Started vConverter to import the VA in to my workstation edition. Ok that went well. While the vm is starting let’s check the installation guide what we need to get it going.
- Requirements for Installing VirtualCenter on Linux
- VirtualCenter on Linux appliance
- Virtualization platform, which can be any of the following:
- ESX Server 3.5 or later
- ESX Server 3i version 3.5 or later
- Workstation 5.5 or later
- VMware Player 2.0 or later
- VMware Server 2.0 or later
- Oracle database, version 10 or later
- Browser with a network connection
Installing VirtualCenter on Linux requires the following items:
- Got the “VirtualCenter on Linux appliance”, “ESX Server 3.5 or later” and “Workstation 5.5 or later” but “Oracle database, version 10 or later” that is a problem. Oracle is not one of the songs in my repertoire. So I need a second Linux distri to install Oracle 10g or later. Searching through the virtual appliances on the VMware site I found this site and downloaded the following distri “Ubuntu Server 8.04.1 LTS (Hardy Heron)”. What else do I need, back to the installation guide. I still need two files, instantclient-odbc-linux32-10.2.0.3-20061115.zip and instantclient-basic-linux32-10.2.0.3-20061115.zip.
I think I have everything I need to get started.
While working with Ubuntu Server I noticed that the swap partition was too small. I’ll describe how this can be fixed. To do this I’ll use gparted download the stable LiveCD.
1. Download Ubuntu Server 8.04.1 LTS (Hardy Heron) and import it to ESX or Workstation
2. Connect the gparted.iso to the Ubuntu vm
3. Then resize the ubuntu-server-8.04.1-i386.vmdk
On ESX vmkfstools –X 9G <lun and folder>/ubuntu-server-8.04.1-i386.vmdk
On workstation <workstation dir>\vmware-vdiskmanager.exe -x 9Gb < folder>/
4. Start the Ubuntu vm and boot from the CD-ROM drive.
5. Start the option “GParted Live (Default settings)”
6. Select your preferred options and start X
7. Select the extended partition /dev/sda2 and resize the extended partition use the maximum space
8. Select the Linux-swap partition /dev/sda5 and resize the Linux swap partition use the maximum space
9. Click Apply to commit the changes
10. Shutdown the Ubuntu vm and change the memory to 512MB
11. Start the vm
12. Login to the vm with “notroot” and the password is “thoughtpolice”
13. Type in “sudo -s” and enter the password “thoughtpolice”
14. After resizing the swap partition it has to be reinitialized
~ # mkswap /dev/sda5
~ # swapon /dev/sda5
15. Configure a Static IP address for your network card. If you want to configure a Static IP address you
need to edit the /etc/network/interfaces and you need to enter the following lines.
~ # nano /etc/network/interfaces
# The primary network interface
iface eth0 inet static
16. Setting up DNS
~ # nano /etc/resolv.conf
enter the following details
17. To install Oracle XE, you need to add the following line to your /etc/apt/sources.list file
deb http://oss.oracle.com/debian unstable main non-free
18. Update the application cache and upgrade the system
~ # aptitude update
~ # aptitude upgrade
19. Installing sshd to do the rest of the installation with putty
~ # aptitude install openssh-server
Answer yes to install the dependencies
~ # reboot
20. Download putty
21. Start putty select ssh and connect to 192.168.242.12
22. Login with “notroot” and the password is “thoughtpolice”
23. Login with sudo as root
~ # sudo –s
password is “thoughtpolice”
24. Install Oracle XE and the client
~ # aptitude install oracle-xe oracle-xe-client

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 :
Specify a port that will be used for the database listener :
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: password
Confirm the password: password

To access the Database Home Page go to "http://127.0.0.1:8080/apex"
Accept the default options and enter the password
26. Let’s try connecting using sqlplus. It’s probably a good idea to do this as a non-root user,
so change to the oracle user. Also, connecting as the oracle user would allow us to connect as sysdba.
~ # su – oracle
27. Oracle needs a couple of environment variables configured for the client to work. You need to alter your
PATH, too. You can put those lines in your ~/.bash_profile and the next time you log in you’ll have your
environment configured correctly. You need to edit the .bash_profile and you need to enter the
~ # nano .bash_profile
if [ -e /usr/lib/oracle/xe/app/oracle/product/10.2.0/server/bin/oracle_env.sh ];
elif [ -e /usr/lib/oracle/xe/app/oracle/product/10.2.0/client/bin/oracle_env.sh ];
28. To save you logging out and in again you can run source .bash_profile
29. After configuring Oracle XE and the environment variables are set. We will start connecting as sysdba
to change the Database Home Page access
~ # sqlplus / as sysdba
SQL*Plus: Release 10.2.0.1.0 – Production on Fri Mar 6 04:08:12 2009

30. Run the following command to enable remote access to the Database Home Page.
PL/SQL procedure successfully completed.
SQL>31. Before we can start the vc installation we need to retrive the instance name from the Oracle DB
SQL>select sys_context(‘USERENV’,’DB_NAME’) as Instance
SQL>from dual; 2
XE is the Database Instance. We need this when we connect vCenter Server to Oracle XE.
This is the end of Part I; watch out for Part II coming soon…

Excellent article. I am using VMWare with CentOS.
The following instruction is key:
Then we have “netstat -an” returning:
tcp 0 0 0.0.0.0:5050 0.0.0.0:* LISTEN
tcp 0 0 127.0.0.1:5050 0.0.0.0:* LISTEN
Note I am using “5050” as port number to access to my Oracle Express instance.
The connection from a remote machine, even using NAT on the VMWare image now works.
Say thanks for share pretty excellent informations. Your internet is great.I am impressed by the material that you have on this weblog. It exhibits how very well you understand this topic. Bookmarked this amazing web page, will appear back again for extra. You, my buddy, amazing! I discovered just the facts I already searched in all places and just wasn’t able to come across.

Like this site your site is 1 of my new most-loved.I such as this knowledge proven and it has provided me some sort of inspiration to have achievement for some reason, so keep up the wonderful do the job!
I require a help from you. In my project there is a vcentre server(v5.0) which is managing two datacentre having 100 servers . Its using a separate oracle server . There was accidental shutdown occurs on both the vcentre and oracle . after , we are not able to see any list in the vcentre.
I have checked with our DBA that oracle database is running fine and its in open state . Its also have tables and size 5 GB.
service on vcentre status is below :
#service vmware-vpxd status
vmware-vpxd is running
tomcat is running
I tried with vpxd_odbcconfig and operation was sucessfull . But, I am not able to get the previous list.
Can you please guide me
1> what should be the status of database open state or mounted ?
2> what is the process to connect the vcenter application with database ?
Nice one you shared a very informative blog. Its really help me to to setup vCenter Server 2.5 on Linux connecting to Oracle XE 10g Release 2 – Part I.
