Here are a few things that you will want to do to your new installation to prepare for installing the database and other components.
Since we are running in VMWare, we don’t want the screen saver activating and locking the application. You can lock the host instead if you need to lock something. Go to the menu System > Preferences > Screensaver.
Uncheck the “Activate screensaver when computer is idle” option.
You will want to install the VMWare Tools in your new image to make it work better. Click on the “Install VMWare Tools” in the VM menu.
And, click the install button to confirm that you want to install the tools.
Give Linux a second or two to mount the virtual CD, and you should see the VMWareTools rpm and tar bar.
Next, double click on the rpm file. You will need to supply the root password before you can continue.
Next, click the Apply button to proceed to installing the tools. You may get a message about malicious software. Since this rpm can from VMWare, we don’t need to worry about it.
Click “Install Anyway” and after a few seconds, the tools should be installed.
Now, we need to make sure that the new service starts automatically upon booting. Open a terminal window, change users to root (with the su command), and run the chkconfig program to add the service. Here are the commands:
/sbin/chkconfig –add vmware-tools
/sbin/chkconfig –list vmware-tools
You will need to install the following packages that are required by the Oracle Database:
libaio-devel (disk 3)
unixODBC (disk 2)
unixODBC-devel (disk 3)
sysstat (disk 3)
To install the package. Insert the appropriate disk the same way that you did for the installation (attach the iso file to the virtual drive or insert a physical CD into the physical drive). Then, on the virtual computer browse to My Computer, CD Drive, Server folder and look for the appropriate RPM file.
Oracle Database requires some kernel parameters to be changed. Don’t worry this is not as bad as it sounds. More information can be found here.
Open a terminal and type:
Now, add the following lines to the end of the file:
# Added for Oracle database
kernel.sem = 1250 32000 100 128
net.ipv4.ip_local_port_range = 1000 65000
net.core.rmem_default = 4194304
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 262144
When your done, save and close the file. Then, run the command:
