Configure VM settings
- We need to change some settings:
- Menue: Maschine - Settings
- Tab: System
- de-select Floppy

- Tab: Storage
- for the IDE controller point the location where you stored your Oracle Linux iso image:
(I choose OracleLinux-R6-U3-Server-x86_64-dvd.iso)

- Tab: Network
- select to
- create Adapter 2 - "host-only"
(I do this, because my host is a laptop and I want to use it in several locations. So with adapter 1 I
will configure a DHCP network, that always connect to the internet by defauld, so I am able to
get packages etc. Databases and application servers need a fixed IP adress, so I will configure
adapter 2 with a fixed IP adress, later.)

- Tab: Shared Folders
- enables to mount this location within my VM, so I can exchange files between Host and Guest.
- I choose my Downloads directory, where I have downloaded the Oracle Datbase and WebLogic
Server.
- Folder name: Downloads
- select auto-mount (so the folder will be mounted automatically when starting the VM)
-> OK

Sometimes, in addition the Host-only network needs defining:

- the login screen appears. As we have only the root user so far, log in as
- root
- root
- password you have set before
-> Log In
- first I add a Terminal start button to the panel
- then I delete the Mail Icon - we will not need it
- now we configure the server with a public-yum server, where to get the latest packages and security
updates from Oracle
updates from Oracle
- start the firefox browser. Navigate tothe page
- public-yum.oracle.com
- public-yum.oracle.com
- scroll down the web page for the "howto configure with Oracle Linux 6"
- open a Terminal
- change to the directory: ("cd" means: change directory)
- cd /etc/yum.repos.d (Linux differs between capital letters!)
- now we download the configuration fire with a command line browser wget:
- cd /etc/yum.repos.d (Linux differs between capital letters!)
- now we download the configuration fire with a command line browser wget:
- wget http://public-yum.oracle.com/public-yum-ol6.repo
- the file shoud be configured to automatically suggest the latest repoitory and Oracle Kernel setting
- if not, edit the file with the famous editor vi:
- vi public-yum-ol6.repo
- change enabled=0 to enable=1 if needed
- now update the Linux packages:
- yum update
- yum update
- y to update suggested updates.
- y for the keys
-
- the kernel updates need a restart of the system:
- reboot
- the following comands are just to chek the running kernel:
- uname -a
- while the lollowing lists installed Oracle kernels:
- rpm -q kernel-uek
- next we will prepare the Linux Server for Oracle. In Oracle Linux 5 the Package oracle-validated
represented a package which creates the oracle user, required groups, sets kernel and security
parameters, limits etc. and required packages. With Oracle Linux 6 oracle-validated has been
replaced by the package "oracle-rdbms-server-11gR2-preinstall"
represented a package which creates the oracle user, required groups, sets kernel and security

replaced by the package "oracle-rdbms-server-11gR2-preinstall"
- to install the package is easy:
- yum install oracle-rdbms-server-11gR2-preinstall
- yum install oracle-rdbms-server-11gR2-preinstall
- enter
- click y to apply
- now, the system also has all required files to build the vboxadditions:
- escape out of the VM (keys are shown in the corner right down: Left "cmd")
- autorun
-> OK
- now we need to set the password for the oracle user:
- passwd oracle
- (remember the password you set!)
- only a few steps to do
- define the fixed IP adress:
- Menue: System - Preferences - Network Connections
- System eth1 - edit
- ATTENTION:
- select connect automatically
- IPv4 Settings:
- Method: Manual
- Address: 192.168.56.60 (192.168.56.x is the defauld VBox network configuration)
- Netmask: 255.255.255.0
- Gateway: 192.168.56.1
-> apply
- select connect automatically
- IPv4 Settings:
- Method: Manual
- Address: 192.168.56.60 (192.168.56.x is the defauld VBox network configuration)
- Netmask: 255.255.255.0
- Gateway: 192.168.56.1
-> apply
- now we need to configure the shared folder between Host and Guest VM. We need to add the VBox
shared folder Group to the oracle user:
- Menue: System - Administration -Users and Groups
shared folder Group to the oracle user:
- Menue: System - Administration -Users and Groups
- select the oracle user:
- properties - scroll down and select
- vboxsf
-> OK
- properties - scroll down and select
- vboxsf
-> OK
- just before the final reboot we need to edit the hosts file:
- vi /etc/hosts
- add the following line:
- IP Address fully qualifies hostname alias
- 192.168.56.60 ol6.de.oracle.com ol6
- safe and close the file:
- esc
- :
- wq!
- vi /etc/hosts
- add the following line:
- IP Address fully qualifies hostname alias
- 192.168.56.60 ol6.de.oracle.com ol6
- safe and close the file:
- esc
- :
- wq!
- ping ol6
- ping ol6.de.oracle.com
- hostname
- create the folders for the oracle software install:
- mkdir /opt/oracle (mkdir: make directory)
- chown -R oracle:oinstall /opt/oracle (chown: change owner des verzeichnisses von root an oracle)
- chmod -R 775 /opt/oracle (Berechtigungen ändern)
- finaly it is a good moment to backup our work:
- poweroff the VM.
- export the VM:
- Menue: File - export Appliance
