Exalogic Elastic Cloud STIGfix v1.0

This blog post is brought to you by Drew Darrow of the Exalogic A-Team, Oracle Product Development.

With the release of the Exalogic Lifecycle (ELLC) Toolkit 14.2, Oracle introduced STIGfix, a tool that can be used to harden guest vServers and physical compute nodes on an Exalogic machine running at minimum EECS 2.0.6.0.0 Virtual or 2.0.0.0.0 Physical.   STIGfix is installed and available for use when you install ELLC 14.2 in your environment.

STIGs are security configuration standards defined by the Defense Information Systems Agency (DISA) an agency within the United States Department of Defense.  More information on STIGs can be found here http://iase.disa.mil/stigs/

Before using STIGfix you must ensure that 'root' is not the only user as once run, direct SSH access to the vServer or compute node as 'root' user will be restricted. Configuring which STIGs are applied to your environment is simple and done by editing the stigfix.json file, which specifies the STIGs the tool will apply or skip.  After running the STIGfix tool, rollback scripts are generated in the backup directory to rollback any STIG you applied that were not intended or had an adverse effect on your application.

Additional considerations :

  • STIGfix can only be run on Exalogic guest vServers or Exalogic Physical Compute nodes, It must never be run on dom0's or control vServers

  • After STIG-hardening your guest vServers you can no longer use ExaBR to backup STIG-hardened guest vServers.  ExaBR only supports STIG-hardened Oracle Linux compute nodes.  The ExaBR Guide has been updated to reflect these changes

  • STIGfix is not supported on EECS 2.0.6.1.2 running the Oracle Enterprise Linux 6 base image

Detailed instructions for use of STIGfix can be found in the STIGfix user guide available at http://docs.oracle.com/cd/E18476_01/doc.220/e53111/toc.htm

Harvard Business Review – IT/Business Users: Overcoming Relationship Challenges to Partner for Success

This blog post is brought to you by Bryan O-Blanquet of the Exalogic Marketing team.

Quickly delivering innovative applications to employees and customers alike is a top priority in the digital economy. But such agility requires big changes in how IT relates to the rest of the business. A new report from the Harvard Business Review that surveyed 274 business and IT professionals concludes that contrary to the popular perception that everything is moving to outsourcing and the cloud, a majority of business managers still prefer to work with their internal IT departments.

Mobile devices, social media and the cloud are disruptive technologies that have transformed information consumption and delivery, affecting how companies innovate and compete.  What separate winning companies from those who struggle to leverage the new disruptors is the agility of how well their IT organizations can respond at the speed of opportunity.  Well, how are organizations doing?  

Responsiveness Drives Revenue
Despite clamoring for stronger IT partnerships, many respondents complained that many IT organizations aren’t structured to support shorter application cycles – identifying a “significant gap” between business needs and IT’s ability to execute timely application cycles. Nearly half said new launches or upgrades happen only once a year or less.  Nonetheless, surprisingly, 56% also said that if their IT departments had more resources, they would still prefer to work with them over outside vendors.  


Top Challenge to Getting Apps to Market?
The most surprising finding is that nearly half the respondents agree that the lack of internal IT partnerships is a top roadblock to digital innovation.  However, the good news is that there’s a growing consensus that IT and business leaders need to collaborate if they’re going to thrive with the new digital disruptive technologies.

•    64% said senior leadership is a vital prerequisite in achieving software innovation and digital success.
•    55 % said it was very-to-extremely important to have operational units influencing innovation in enterprise applications.
•    44 % said IT and business units should share the responsibility equally.


The most important conclusion in the report is that to align business and IT, organizations must eliminate the complexities that distract IT and hinder progress. This requires new approaches to architecture along with organizational changes.

To respond quickly with speed and agility to new business opportunities, a critical first step is for IT to get data to flow across multiple systems and platforms that are today too often a mess of disconnected legacy systems. Systems need to be simpler to procure and operate. It’s no wonder that integrated systems are growing at 35% according to IDC. Integrated systems, which include server, storage, networking, and management software, eliminate much of the cost and complexities that come with traditional systems.

IT must translate business requirements and terms into an agile platform that leverages data, cloud, mobile and social. This requires a substantial reinvention of  IT processes, new platforms, and strong partnerships between business leaders and IT management.

Solaris 11.2 (EECS 2.0.6.2.0) EoIB Administration

This blog post is brought to you by Leo Yuen of the Exalogic A-Team of Oracle Product Development.

With the release of EECS 2.0.6.2.0, customers can now run Solaris 11.2 on any model of Exalogic.  For existing Solaris customers, applying January 2015 PSU will upgrade their compute nodes to Solaris 11.2.  Among all the cool new features that come with Oracle’s latest enterprise-grade operating system, the dladm command has been updated with additional subcommands to manage Ethernet over InfiniBand (EoIB).

  • The "dladm show-ib" subcommand has been enhanced to display all InfiniBand switches information and the partition keys that a compute node belongs.

  • The "dladm create-eoib" subcommand is used to create eoib datalink object to match with the VNIC created on the switch.

The Exalogic Machine Owner’s Guide has been updated to reflect the above changes. Please refer to this document for instructions on how to setup VLAN-tagged VNICs and sample outputs of the new commands.

Exalogic Elastic Cloud 12c Software and X5-2 Hardware Launch

Today’s blog post is brought to you by Oracle Product Manager Kelly Goetsch.


We're excited to announce the release of the first of two fundamental innovations in Oracle Exalogic - our planned 12c Exalogic Elastic Cloud Software and our new X5-2 hardware, the latter of which is available immediately.

Beginning with software, we're seeing a massive shift from traditional pure virtualization to cloud. In our 12c release, Exalogic is aligning with Oracle's public cloud to offer the same IaaS and PaaS layers, with Java Cloud Service being offered as our first PaaS solution. By adopting the same IaaS and PaaS layers, we're able to offer our customers the exact same experience whether on or off premise. Performance continues to be a defining characteristic of Oracle Exalogic, with workloads having 5-10x greater performance and throughput compared to traditional systems.

To see how we got to this point, let's look back at the 1990s.That era was characterized by big monolithic apps running on large, non-virtualized servers. This is known as "Generation 0." In the 2000s, many workloads were virtualized. This is known as "Generation 1." While an enormous evolution over physical, virtualization didn't change the equation all that much - in fact it made it worse. Rather than having one large server, there are many smaller virtual machines. The maintenance problems only multiplied as it became easier to provision virtual machines.

In today's world, cloud is beginning to take over and Oracle is the leading vendor in the transition to cloud. Cloud is known as "Generation 2." Cloud offers virtualization as well but it offers a number of new features that make it distinct from Generation 1. Cloud offers simple provisioning, elasticity to support ever-changing workloads, automated backup/recovery/patching and more. Resources - from compute to network to storage to Java - are offered up as services, with the consumer of the services detached from the back-end work required to offer and maintain the services. As much as possible, end-consumers provision some software, with the hardware behind the software being provided, configured, updated, backed-up seamlessly. Cloud is often consumed off premise, but with the introduction of Exalogic Elastic Cloud Software 12c, customers will be able to consume the same IaaS and PaaS services in Oracle's public cloud, or on premise on Oracle Exalogic hardware.

Exalogic X5-2 is the next Generation of our hardware platform, built to support Generation 2 (although the 12c software will support existing hardware platforms). Ahead of defining specifications for the platform, we performed extensive research to look at how we can continue to have a balanced architecture to support the workloads our customers have. Thinking of Exalogic X5-2 in the context of a Generation 2 cloud model, high density of virtual machines on each individual server is a prerequisite, in addition to a shared network, storage system and most important, high I/O throughput (which is achieved through Exabus on Exalogic). In order to deliver on a balanced architecture, we've increased the density of cores per compute node up to 36, meaning customers can have up to 1,080 physical cores in a single rack of Oracle Exalogic X5-2. There are a number of other enhancements including a move to DDR4 to provide faster memory, an increase in SSD per compute node to 800 GB, and an 800 GB write cache in our storage appliance. Collectively, these changes make Exalogic X5-2 the best available hardware platform for Generation 2 computing.

To learn more, have a look at the Elastic Exalogic Elastic Cloud X5-2 launch video.

E-Business Suite on Exalogic and Exadata

This blog post summarizes important references available for E-Business Suite customers on Exalogic and Exadata.

For general E-Business Suite recommendations, refer to the current quarterly blog post on the E-Business Suite Technology blog.

For new deployments/installations of E-Business Suite on Exalogic and Exadata, refer to MOS Doc 1460742.1 - Deploying Oracle E-Business Suite on Oracle Exalogic Elastic Cloud and Oracle Exadata Database Machine.

Migrating an existing E-Business Suite to Exalogic and Exadata consists of two major phases -
1. Migrating the E-Business Suite database to Exadata - detailed steps in MOS Doc 1133355.1
2. Migrating the E-Business Suite application tier to Exalogic - detailed steps in MOS Doc 438086.1

The list of E-Business Suite (and other software) versions that are currently supported on Exalogic are documented in MOS Doc 1302529.1

Best practices for managing concurrent manager log and out directories are outlined in MOS Doc 1616827.1 - these recommendations are applicable to all platforms, and there is a specific reference pertaining to Exalogic.

E-Business Suite VM templates built specifically for Exalogic are available -
1. For 12.1.3 VM templates, see details in MOS Doc 1499132.1
2. For 12.2.3 VM templates, see details in MOS Doc 1633952.1

These templates provide an easy way to quickly install the latest EBS software bypassing the traditional "install from media and then apply the latest EBS database/techstack/application patches" method. Customers can customize these installs as appropriate and create their own templates as outlined in the Exalogic documentation. Although these templates will create an E-Business Suite database on a Linux VM running on Exalogic, for optimal performance it is recommended that the EBS database tier be migrated to Exadata.

The E-Business Suite 12.1.3 Maximum Availability Architecture whitepaper for Exalogic and Exadata outlines various OS and storage best practices specific to E-Business Suite on Exadata and Exalogic that customers should uptake.

Various functional whitepapers, authored by EBS product teams, detailing the advantages of running E-Business Suite on Engineered Systems are also available.

There are several other documents that EBS customers may find useful -

MOS Doc 1934250.1 - CVE-2014-7169 Patch Availability for Oracle E-Business Suite (Bash Code Injection Vulnerability)
MOS Doc 1924645.1 - Intermittent Application Hangs Occur On An Exalogic Physical Or Virtual Server Due To A Race Condition That Occurs While Updating Memory Mapped Files Located Under NFS
