I'm currently moving a customer to Oracle Linux from Windows and helped out our system administrator who was on site with a list of packages needed for an Oracle Database and Ebusiness Suite ( oracle-validated took care of most things).
Its actually a great project to be involved with as we are using VMware and have created template images to deploy new environments as needed. It takes about 20mins to create a new machine which is already configured and has the Oracle Database 11gR2 software installed.
Of course in any deployment there have been missing packages not listed in Oracles Documentation(but they are on oracle support as notes for some reason) and interactions with the GUI's when running the installers.
At the start I was using xhost + to help with the GUI's , but having come from a support background, I realized I was breaking a big rule. I promised myself that once involved with projects i'd stay away from root as much as possible( a bad experience where a person installed the oracle RAC clusterware as root).
So I needed to work out how to stop using xhost +
Answer :
The below turns back on the access control lists
$ xhost -
The below add the oracle user to the list and the local IP
$ xhost +SI:localuser:oracle
$ xhost + hostname
The second thing bugging me was that the templates were on dhcp and could use yum for installing the packages but with the cloned vm's , no such luck as they were static and locked down. I found a great note on mounting the media dvd and creating a custom yum repository which could then be used.
The steps are below :
# mkdir
/media/disk
Insert EL5.7 DVD
(or attach to your Oracle VM guest)
# mount
/dev/cdrom /media/disk
Edit
/etc/yum.conf, adding the following section:
[EL5.7
DVD]
name
= Enterprise Linux 5.7 DVD
baseurl=file:///media/disk/Server/
gpgcheck=1
enabled=1
# yum install
oracle-validated
The last step was to go back to the template and update it with all the lessons learned from the first couple of environments.
