Leveraging Linux Patching with Enterprise Manager 13.2

EM13.2, Oracle 3 Minutes

I will have my Enterprise Manager server and Linux Packages Repository Server on two different hosts. (It doesn’t have to but my EM server and database is running on ODA X7-2-S so it is a little tight on storage)

em-host Enterprise Manager Software, EM database
repo-host Linux Repository

EM 13.2 Installed and EM 13.2 agent is already deploy to repo-host.

Repo-host configuration

Since the linux host i build from template is setup for spacewalk, remove the current RHN setup.

yum remove rhn-setup

yum remove rhn-client-tools

yum remove rhn-check

I have a BIG DISK mounted on /linux_repo to store all the Linux packages

cd /linux_repo

wget http://linux-update.oracle.com/rpms/uln_register.tgz

wget http://linux-update.oracle.com/rpms/uln_register-gnome.tgz

tar -xzf uln_register.tgz

tar -xzf uln_register-gnome.tgz

total 488

yum remove yum-plugin-ulninfo
yum remove rhnlib
yum remove yum-rhn-plugin
yum remove rhn-setup
yum remove rhn-setup-gnome
yum remove rhn-check
yum remove-client-tools-migrate

(some of the above packages might get remove due to another dependency yum packages)

take a backup of /etc/yum.repos.d/public-yum-ol6.repo  (Remove or Disable any spacewalk channels on /etc/yum.repos.d/*.repo file.)

Use oracle public yum repository to install the uln migration package. i.e Enable Ol6 latest channel. (Only enable ol6_latest)

yum repoinfo

Ensure you are getting correct repo, i.e ol<#>_latest, not from ol<#>_spacewalk repo.

cd /linux_repo/uln_migrate

yum install rhnsd

uln_register

Required Oracle Single Sign-On Login email, password and CSI number.

rpm_packages

yes_ksplice

Now go into linux.oracle.com, edit the setting of current server on linux.oracle.com. Enable “Yum Server” so you can subscribe to other version of Linux channel

Deploy EM 13.2 agent to the repository server

(It is crucial that you create this symbolic link)

mkdir -p /var/www/html

cd /var/www/html/

ln -s /linux_repo/repo yum
