Most of the times while we are installing prerequisites for the oracle installation, its some what painful to get the updated rpms and dependencies<\/strong>, especially in Redhat Enterprise and Oracle Enterpirse version 4.\u00a0 The following document explains us to overcome this issue.<\/p>\n

Yum<\/strong> is the easiest way to keep all programs up to date. It downloads and installs the latest version of a program. A single command can update all software installed, including third-party software, security updates and operating system. In this howto, we install yum (on Redhat&Oracle Enterpirse OS ) and make it do all the above.<\/p>\n

First remove the installed yum rpms.<\/p>\n

\u00a0# rpm -e `rpm -qa|grep yum`<\/strong><\/pre>\n
Go to the folder where you want to download yum. Most likely cd \/tmp\/.<\/p>\n
# wget -c http:\/\/dag.wieers.com\/rpm\/packages\/yum\/yum-2.4.2-0.4.el4.rf.noarch.rpm<\/strong><\/pre>\n
# rpm -ivh yum-2.4.2-0.4.el4.rf.noarch.rpm<\/strong><\/pre>\n
If you can see the file with ls, you are on the right place.<\/p>\n
Delete all the repository file in the \/etc\/yum.repos.d\/<\/p>\n
# cd \/etc\/yum.repos.d\/\r\n# rm -rf *<\/pre>\n
Create a \u00a0new Base file in \/etc\/yum.repos.d and add the contents<\/p>\n
# vi \/etc\/yum.repos.d\/CentOS-Base.repo<\/pre>\n

Restart the yum service and now you are ready to update or install any packages.<\/p>\n
Add trusted packagers to your keys<\/h4>\n
In yum, it really does not matter if enemy<\/strong> takes over the internet and fakes to be some website offering software. All software is cryptographically checked before installation (if you have set gpgcheck=1 in yum.conf<\/strong>). To install some software, we must tell yum who we trust.<\/p>\n
For the first update or install of any package, it asks to import Trusted Key’s.\u00a0 Now you need to just press “Y”.<\/p>\n
Is this ok [y\/N]: y<\/pre>\n
<\/pre>\n
If you are\u00a0 unable to find the updates from the Vendor repository, use dag.wieer<\/strong> repository rpm where you can find all rpms and dependencies details.<\/p>\n
# rpm -Uhv http:\/\/apt.sw.be\/redhat\/el4\/en\/i386\/rpmforge\/RPMS\/rpmforge-release-0.3.6-1.el4.rf.i386.rpm<\/pre>\n
# service yum restart<\/pre>\n
Now you can install any package for this architecture.<\/p>\n
