Technical Whitepaper: Oracle Solaris Immutable Zones for SAP Installation

This paper provides instructions and best practices on how to create and manage an SAP installationon an Oracle Solaris Immutable Zone. An Immutable Zone is a security mechanism that can be used to control the way users access files, protect system databases and applications, allow read-only virtual machines, and freeze the operating system and hardware configuration to prevent changes. An Oracle Solaris Immutable Zone obtains the zone’s configuration by implementing read-only root file systems for non-global zones, global zones and kernel zones.

 

The goal of this document is to increase security features on the Oracle Solaris operating system by defining a non-global zone, global zone or kernel zone as an Immutable Zone and running the SAP application on this read-only zone. With this strategy, the system is made safer. The procedure is tested by simply setting the zonecfg file-mac-profile property for various SAP releases with Oracle Database 11g and 12c...

One of the things that amazes me about Oracle is how active its staff and product groups are in their blogs. In addition to all the traditional technical resources available through the product marketing and support channels, engineers and product managers maintain some amazingly active blogs where they post regularly about:

  • how to address issues that they see customers face,
  • how to do things with Oracle systems that only the super experts would know how to do,
  • and, otherwise provide amazing free educational material for system administrators and developers everywhere.

A notable blog I want to highlight today is "Fore! - Stray shots from Dave Miner." Dave Miner is the architect for Oracle Solaris deployment and system management, has a lot of background in networking on the side. He spends a lot of time operating Oracle Solaris Engineering's OpenStack cloud and is coauthor of the OpenSolaris Bible (Wiley, 2009).

 

Needless to say, he knows his stuff.

 

Earlier this month, he posted about troubleshooting I/O loads in an Oracle Solaris OpenStack Cloud environment that I wanted to highlight by turning it into an official OTN community article here on community.oracle.com.

 

Enjoy!

 

Article: Troubleshooting I/O Load in an Oracle Solaris OpenStack Cloud

 

Tips for how to determine what's causing slow disk I/O in an Oracle OpenStack for Oracle Solaris cloud environment. By Dave Miner-Oracle

"The other day we noticed that a number of guests running on our Oracle Solaris OpenStack cloud were very lethargic, with even simple operations like listing boot environments with beadm taking a long time, let alone more complex things like installing packages.  It was easy to rule out CPU load on the compute nodes, as prstat quickly showed me that load averages were not at all high on the compute nodes hosting my guests....[Click Here to Read More]"

White Paper: Using Oracle Ksplice as a Diagnostic Tool with Oracle Support

 

One of the most powerful and often overlooked features of the Ksplice feature of Oracle Linux is its ability to be used as a diagnostic tool for troubleshooting issues with the Oracle Linux Kernel. Ksplice allows for diagnostic patches to be loaded into the kernel in real time without the need to reboot. This article will provide additional insight to how this process works when working with Oracle Support.

By Bjoern Rost


Puppet is a popular open source configuration management tool that is used by many organizations to automate the setup and configuration of servers and virtual machines. Solaris 11.2 includes native support for puppet and extends the resources that can be managed to Solaris specific things like zones and ZFS. This presentation will give system administrators that are new to puppet an introduction and a way to get started with automating the configuration of Oracle Linux and Oracle Solaris systems, talk about how puppet integrates with version control and other projects and look at the Solaris specific resource types.
