Installing Spacewalk to manage Oracle Linux

Spacewalk is a popular Linux management tool that can be used to manage several operating systems, including the Red Hat Enterprise Linux derivatives like CentOS and Scientific Linux, Debian and even Solaris.

While the Spacewalk installation instructions are very thorough, here is a brief guide to installing Spacewalk on Oracle Linux 6. It is possible to install on Oracle Linux 5, but it requires a lot more manual intervention as the Unbreakable Linux Network packages installed on Oracle Linux 5 conflict with some Spacewalk packages. You should use both the Spacewalk installation instructions in combination with this guide to install Spacewalk.

Pre-requisites

This guide assumes that you are familiar with the Oracle Linux 6 installation process, as well as basic system administration tasks, including registering with the Unbreakable Linux Network (ULN) or configuring YUM to use public-yum.oracle.com.  The Oracle Linux 6 Administrator's Solutions Guide provides more information on these tasks.

Oracle Linux 6 Installation

This guide uses Oracle Linux 6.4 (x86_64). Download Oracle Linux 6.4 from the Oracle Software Delivery Cloud or one of the mirrors. You can choose either to do a "Basic Server" install, or a "Minimal" install. I recommend performing a "Basic Server" install as this provides basic system administration tools. If you are using a previous version of Oracle Linux 6, please ensure it is either registered with the Unbreakable Linux Network or is configured to use public-yum.oracle.com for updates.

You should assign both a fixed hostname as well as a fixed IP address for your Spacewalk server. The hostname should be resolvable via DNS on your network.

Pre-Requisite Installation

Binary packages of Spacewalk are available through YUM repositories at http://yum.spacewalkproject.org/. To use this repository, install the spacewalk-repo package with commands below:

# rpm -Uvh http://yum.spacewalkproject.org/1.9/RHEL/6/x86_64/spacewalk-repo-1.9-1.el6.noarch.rpm

Additional repositories and packages

For Spacewalk on Oracle Linux 6, additional dependencies are needed from JPackage. Please configure the following yum repository before beginning your Spacewalk installation:

cat > /etc/yum.repos.d/jpackage-generic.repo << EOF
[jpackage-generic]
name=JPackage generic
#baseurl=http://mirrors.dotsrc.org/pub/jpackage/5.0/generic/free/
mirrorlist=http://www.jpackage.org/mirrorlist.php?dist=generic&type=free&release=5.0
enabled=1
gpgcheck=1
gpgkey=http://www.jpackage.org/jpackage.asc
EOF 

We specifically want the 5.0 generic directory in the above URL.

Spacewalk requires additional dependencies from the Enterprise Packages for Enterprise Linux (EPEL) repository. To enable this repository run the following command:

# rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm 

Database Server

Spacewalk supports either Oracle Database 10g or higher or PostgreSQL 8.4 or higher to store its primary data. While Oracle Database XE is supported by Spacewalk, it is not supported by Oracle. Therefore, we recommend either using an existing Oracle Database Standard or Enterprise Edition server or using PostgreSQL. 

Oracle Database Setup

Installation of an Oracle Database server is outside the scope of this walk-through. We assume you have an existing Oracle Database server installed and available. The spacewalk user needs to have the CONNECT and RESOURCE roles as well as the ALTER SESSION, CREATE SYNONYM,CREATE TABLE and CREATE VIEW system privileges.

You will also need to make the following code change on your Spacewalk server, after you have installed the Spacewalk software:

# diff -u /etc/sysconfig/rhn/oracle/main.sql-20110504 /etc/sysconfig/rhn/oracle/main.sql
--- main.sql-20110504	2011-04-08 21:40:53.000000000 +0200
+++ main.sql	2011-05-04 14:20:24.000000000 +0200
@@ -38940,6 +38940,12 @@
 
 
 -- Source: data/common/rhnPackageSyncBlacklist.sql
+
+select lookup_package_name('gpg-pubkey') from dual;
+
+select lookup_package_name('rhns-ca-cert') from dual;
+
+select lookup_package_name('rhn-org-trusted-ssl-cert') from dual;
     
 insert into rhnPackageSyncBlacklist (package_name_id)
 	values (lookup_package_name('gpg-pubkey')); 

Without this change, the Spacewalk installation fails with the following error in /var/log/rhn/populate_db.log:

ORA-02291: integrity constraint (SPACEWALK.RHN_PACKAGESYNCBL_PNID_FK) violated - parent key not found 

The Oracle Instant Client packages can be installed from ULN by subscribing to the Oracle Software channel and running the following command:

# yum install oracle-instantclient11.2-basic oracle-instantclient11.2-sqlplus

If you are not subscribed to ULN, you can download the Oracle Instant Client RPMs from the Oracle Technology Network and install them manually.

Once the Oracle Instant Client has been installed, you need to add the library path to ldconfig:

# echo /usr/lib/oracle/11.2/client64/lib > /etc/ld.so.conf.d/oracle-instantclient11.2-basic.conf
# ldconfig

Spacewalk Installation

If you want to use the PostgreSQL embedded backend on the same server as Spacewalk:

# yum install spacewalk-setup-embedded-postgresql 
# yum install spacewalk-postgresql

If you want to use an Oracle Database backend:

# yum install spacewalk-oracle 

The rest of this guide uses an Oracle Database backend. Don't forget to make the code change listed under Oracle Database Setup before continuing!

The Spacewalk binary packages are missing a dependency on the geronimo-jta-1.1-api RPM, so install it manually:

# yum install geronimo-jta-1.1-api

Configuring Spacewalk

Your Spacewalk server should have a resolvable FQDN such as 'hostname.domain.com'. If the installer complains that the hostname is not the FQDN, do not use the --skip-fqdn-test flag to skip.

If you installed spacewalk-setup-embedded-postgresql above, run

# spacewalk-setup --disconnected

If you set up the database server manually (either on the same or on a different machine), run

# spacewalk-setup --disconnected --external-db

Oracle Linux and Oracle VM pre-validated, pre-tested with FlexPod

As the Oracle community is gathering at IOUG this week sharing news, checking out the latest innovations, the Oracle VM and Oracle Linux team are also busy working to expand our platform validation support. In a collaborative effort with both Cisco and NetApp, we’d like to give you an early glimpse of the upcoming reference architectures for Oracle Linux and Oracle VM with FlexPod:

  • A FlexPod with Oracle VM is scheduled for the second half of 2013  – this Oracle VM architecture offers virtualization coverage for Oracle as well as non-Oracle workloads
  • A FlexPod featuring NetApp Clustered Data ONTAP with Oracle Linux,  coming Jun 30, 2013 – this is the second Oracle Linux bare-metal design
  • A FlexPod with Oracle Linux, coming June 14, 2013 – this is one of two bare metal designs for running Oracle DB on Oracle Linux
The combined products give customers access to infrastructure designs that are pre-tested and pre-validated building blocks for application consolidation, private cloud migration or data center modernization.
In addition to the benefits of the integrated design and validation, there are specific unique benefits that Oracle VM and Oracle Linux add to FlexPod:
  • Oracle VM – Application-Driven Virtualization difference: Speed Dev/Test/Production application deployment – Using Oracle VM Templates, customers can deploy applications 7-10x faster than traditional virtualization approaches. Entire application stacks including guest OS with Oracle Linux can quickly be deployed or provisioned in hours or minutes. This empowers IT to have a direct impact on the business Quality of Service by enabling more test systems and or respond to end customer requirements more quickly.
  • Enhanced high availability with Oracle Linux: With Ksplice, Oracle Linux kernel updates are installed in seconds, without interrupting running applications or the people using those applications. You can quickly check on the current status of your systems before rolling out updates to your network. Installing updates requires no downtime, so your systems are more available than ever.
  • Certified by Oracle: All Oracle applications are certified on Oracle VM. This gives customers peace of mind that FlexPod with Oracle VM running Oracle applications are both fully tested and  certified by Oracle
  • Reduce Licensing Cost: with zero licensing cost for both Oracle VM and Oracle Linux and low enterprise support cost, customers can dramatically reduce both capex and opex IT spending. 
We’ll keep you updated as these reference architectures get published. Like us on Facebook or Follow us on Twitter to stay informed.

Reasons You Should Consider Migrating From SUSE Linux (SLES) to Oracle Linux

Each day we receive inquiries from Oracle customers who are interested in migrating from SUSE Linux Enterprise Server (SLES) to Oracle Linux.  As a result, we hosted a webcast to provide additional information for customers who are considering migration and there are a few key points from the webcast I would like to share.

First, I believe all Oracle customers benefit from using Oracle Linux for their Oracle workloads.  Oracle Linux is the corporate Linux standard for all development groups at Oracle.  The Oracle products you use are developed on Oracle Linux.  This development standard creates a natural synergy between Oracle Linux and the Oracle application stack.  Oracle Linux receives over 128,000 hours of testing  from Oracle products, including extensive regression testing, while SLES receives only basic installation testing as an operating system. 

Oracle Linux subscriptions also offer tremendous value.  With Oracle Linux Basic and Premier Support subscriptions you receive 24x7 support, 365 days per year with unlimited incidents. Compared to SLES, Oracle Linux can significantly reduce your operating expenses which translates directly to your bottom line.   Let's take, as an example, a 4-socket system hosting several virtual machines with 24x7 support:

 Oracle Linux Basic Support Subscription
 SLES Priority , 4-socket, Virtual Subscription
 $1,199 annually (per server)
 $3,878 annually (per server)

As you can see in the table, the SLES Priority Subscription list price is $3,878 annually, per server.  For Oracle Linux, the equivalent Basic subscription would be $1,199, about 69% less.   If you had 100 servers in your data center, this would be an annual savings of $267,000!   In addition, the Oracle Linux Basic and Premier Subscriptions include solutions for high availability and system management, at no additional charge.  To receive these features with SLES, you must purchase additional extension subscriptions per server.  Using the previous example, for the SUSE Linux High Availability extension you will pay an additional $1,398 for each 4-socket server in the cluster, per year.  This now represents a 77% savings with Oracle Linux.  If you want to use their system management tools, there is a separately priced extension.  As you can see from the example, the SUSE extension-based pricing model quickly adds up.  With Oracle Linux, our pricing is straightforward and subscriptions include more features, providing greater value for you.

There are also features you will only find with Oracle Linux.  For example, what if I were to tell you Oracle Linux provides all bug and security errata on our public yum repositories and it is free, would you be interested?  With Oracle Linux, you receive:

  1. Free ISO downloads for each major and minor releases
  2. Free software channels for bug fixes and security errata
  3. All source code, including changelogs, for free.  No subscription required.
  4. The ability to freely redistribute without a requirement to modify copyrights, trademarks, or sign additional agreements
  5. Freedom from restrictive support term requirements to cover all systems with subscriptions.  Oracle Linux support is only required for systems that you intend to receive support services for.  Systems that are static, and don't need support (testing, development, etc.) do not have to be covered by a subscription.

With SLES, you can download the product under a 60-day evaluation, but after 60 days you'll need a subscription if you wish to receive any further updates to the software or to access the source for those updates.  You will not have access to the changelogs for the source and if you want to distribute you will need to remove all trademarks, trade dress and logos before doing so.  In addition, depending on your buying program, you may be required to cover every instance of SLES with a subscription, regardless of whether you require support for that system.

There are also unique features for Oracle applications which are offered only with Oracle Linux.  One example is Oracle Database Smart Flash Cache.  Introduced originally with Oracle 11g Release 2, Oracle Database Smart Flash Cache provides the ability to extend the database buffer cache without adding additional main memory by expanding to second level cache on flash memory.  This ability to leverage flash improves Online Transaction Processing (OLTP) environments by improving transaction throughput and application response times.  Oracle Linux is the only Linux distribution with support for this feature. 

Also, have you ever considered what the actual cost is for system downtime in your data center?  Every data center schedules maintenance for production environments and for every maintenance window needed, an administrator must coordinate with multiple groups to plan and schedule downtime.  When you consider large systems, like the Oracle database, the man-hours needed to coordinate, schedule and implement maintenance updates quickly add up.  What if I told you Oracle Linux Premier Support subscriptions include Ksplice, a service for installing kernel updates without requiring a system reboot.  Ksplice eliminates many of the common maintenance scenarios which result in a system restart, allowing administrators to keep up to date with the latest kernel errata, without bringing down the server.

Finally, let's end by talking about support.  As everyone knows, Linux is open source and when you choose to purchase subscriptions for Linux, you are buying access to a vendor's knowledge and expertise.  With Oracle Linux, customers have access to the best support professionals in the industry, who not only understand the operating system but they also understand the Oracle applications running on it.  You will spend less time being shuffled from vendor to vendor when you have a critical issue, producing quicker resolutions for your production systems.

I have highlighted several key reasons why you should consider a migration from SLES to Oracle Linux and I encourage you to  review the materials we have available on the Migration Made Easy web site, where you will find additional tips and guides to get you started.  If you have additional questions or you are ready to talk about your migration, please contact us for more information.

Announcing Ksplice Inspector!

Everyone knows a good inspector is crucial when buying a home or looking for clues in a "whodunit". And now you also have an "inspector" for your Linux kernel!

Today Oracle released a new tool called the Ksplice Inspector enabling Linux users to analyze kernel updates available for their Linux kernel. With so many kernel updates released, it can be difficult to keep track. At Oracle, we monitor kernels on a daily basis and provide bug and security updates administrators can apply without a system reboot. To help out, the Ksplice team at Oracle has produced the Ksplice Inspector, a web tool to show you the updates Ksplice can apply to your kernel with zero downtime.

Read the Ksplice blog article for more details on this new tool and who can use it.

Q&A About the Latest Oracle Linux Releases

We sat down with Monica Kumar, Senior Director, Oracle Linux, Oracle Virtualization, and MySQL Product Marketing, to discuss the latest update on Oracle Linux.


Q. What are the latest Oracle Linux releases? 

A. Oracle Linux 5.9 and Oracle Linux 6.4 represent the latest releases of Oracle Linux. These releases are built on top of Oracle Linux 5 and 6 respectively and include updates supporting new hardware and driver features, as well as bug fixes and security updates. For additional details, please see the 5.9 release notes and 6.4 release notes.

Q. Why would customers want to update their Oracle Linux systems to the latest release? What advantages will it give them?

A. Updates play a critical role in the overall lifecycle of an operating system release. An update release provides an opportunity for customers to leverage new hardware features as well as apply critical bug fixes and security updates. Oracle Linux 5.9 is also a consolidation of previously released errata published since the release of 5.8 – and the same holds true for 6.4. As part of Oracle Linux, we also offer an innovative and modern kernel – Unbreakable Enterprise Kernel. The combination of Unbreakable Enterprise Kernel with the latest bug fixes and new hardware support helps improve performance, enhance stability and enable systems to remain secure.

Q. Why do customers choose Oracle Linux? What do they get from Oracle Linux that they couldn't get by using RHEL or SUSE or a non-commercially supported distribution?

 A. Oracle Linux offers many benefits. Key benefits include:

  1. Technology: Latest innovations (with tracking mainline, optimizations from Oracle Engineered Systems, and Unbreakable Enterprise Kernel is the culmination of this technology excellence, offering enhanced performance, reliability and a more modern Linux distribution), as well as unique features such as Ksplice, DTrace, and support for popular file systems including ocfs2 besides the others.
  2. Testing/ Deployment best practices: over 100,000 hours of QA/day using Oracle Linux – most tested distribution with enterprise workloads and over 160 validated configurations.
  3. Support: 24/7 world-class Linux support in 145 countries; by far the widest and largest support network over Red Hat or SUSE
  4. Cost: Lowest cost support
  5. Free Access to software: free download of binaries and patches

Read detailed information regarding RHEL vs Oracle Linux

Q. What does Oracle give back to the Linux kernel community?

A. New Linux kernel development is focused on working with Linus and the mainline kernel community, where we, like other Linux distribution vendors, contribute significant amounts.  Over time, those mainline development projects trickle down into an OS distribution like Oracle Linux 6 through Unbreakable Enterprise Kernel which is a great vehicle – and how we introduce new Linux kernel features into Oracle Linux and provide it to customers. Oracle has a long history of developing open source projects and working with the Linux kernel community. We are active contributors to many features found in the mainline kernel today, including OCFS2, Btrfs, NFS, XEN, to name just a few. In addition, our business model for Oracle Linux is to focus on providing the best operating system for mission critical workloads, and contributing the work we do back to the mainline community. Our git repository for the Unbreakable Enterprise Kernel is publicly available on oss.oracle.com/git so anyone can see our development work and our contributions. In addition, we make Oracle Linux freely available, including all of our errata, whether you have a support subscription or not.

See this link for more on Oracle’s contributions to Linux.

Q. Why is Oracle Linux better for customers than using the most current version of Red Hat Enterprise Linux? What's the value for customers?

A. Oracle Linux including the Unbreakable Enterprise Kernel  is developed to provide high performance and stability for mission-critical applications. Users benefit from the innovations and improvements occurring in the mainline Linux community, which we deliver rapidly with Oracle Linux. In addition, Oracle Linux is the most well tested distribution for enterprise workloads, especially Oracle workloads. We conduct over 100,000 hours/day of testing at Oracle using Oracle Linux. Additionally, support of Oracle’s Engineered Systems plus the enterprise application knowledge that we have, is unmatched by our competitors.

The technical support we provide with Oracle Linux also includes important bug fixes that Red Hat may choose not to release. For our customers, these fixes are critical and it is one of the many reasons they choose Oracle Linux. In addition, with capabilities like zero-downtime kernel updates through Ksplice, they receive features that are not offered by Red Hat.

Q. What is being planned for the next release and what is the predicted timing of the next release?

A. Oracle continues to focus on features which improve performance and the innovations found in the mainline Linux community. We are currently working on the next generation of the Unbreakable Enterprise Kernel for Oracle Linux.

We expect update releases for both Oracle Linux 5 and Oracle Linux 6 and a new release of the Unbreakable Enterprise Kernel in calendar year 2013.
