Oracle Sponsors LinuxCon Japan - June 3-5


Oracle is a bronze sponsor at LinuxCon Japan that is happening in Tokyo, June 3-5, 2015. We have two great sessions and a booth to showcase Oracle Linux and related products. Oracle Linux team will have experts available to answer your questions and give you more information about our products. 

Here are the Oracle sessions: 

1) Exciting Developments in Linux Tracing - Elena Zannoni, Oracle

Thursday, June 4 • 16:20 - 17:10

Tracing in Linux today has become quite main stream. Linux has come a long way from when the first attempt to insert tracing infrastructure and tools in the kernel tree was made several years ago. But where are we now? While existing tools are being refined and more sophisticated features are added to them, there are still fundamental areas where improvement is happening and exciting new approaches are surfacing, such as using the BPF (Berkeley Packet Filtering) infrastructure for tracing purposes, for instance. This talk is a new and revised version of my previous tracing talk with specific emphasis on new developments as opposed to providing an overview of the field. 

2) Open Source Tools for Enterprise Class Documentation Writing - Elena Zannoni, Oracle

Friday, June 5 • 11:30 - 12:20

This talk will give an overview, with some examples, of how it is possible to produce first class documentation using Open Source Tools. The use of DocBook XML and a variety of other programs, together with an automated build system written in house has produced very good results in our enterprise documentation team. We build all our Linux, Virtualization and MySQL docs using this system. 

Don't forget to visit our booth and attend our sessions.

FRIDAY SPOTLIGHT: Implementing Facebook’s Flashcache Utilizing PCIe-based Flash with Thin Provisioning

This Friday we would like to share with you a great article by Rick Stehno from Seagate who frequently writes articles about Oracle Linux, MySQL and Oracle Database. 

PCIe-based flash can help increase the performance of a database application, such as MySQL on the Oracle Linux platform that delivers the storage performance to contend with the massive data deluge brought on by the mobile Internet, cloud-based services, and enterprise applications. By enabling a thin provisioning feature, low latency and improved performance is achieved, usable flash capacity is expanded and overall TCO is lowered. 

Oracle Linux running the default Unbreakable Enterprise Kernel (UEK) was chosen for this study because of its upstream support for the latest hardware relevant to modern data center operations. In addition, MySQL database workloads benefit from the platform’s deep integration with the solution stack, optimizations resulting from industry collaborations and enhancements in the UEK. Oracle Linux with UEK was tuned to perform better and faster on leading-edge x86 configurations that feature many CPU cores and large amounts of main memory, and optimized libraries and system calls help to improve performance for MySQL queries. Because of these optimizations and pervasive testing that occurs within Oracle, Oracle Linux is able to address large transaction capacities and scale well as the number of database users or the number of databases increases.

Thin provisioning, such as with the Nytro Dynamic Logical Capacity (DLC) technology, adds significant value to caching environments where the user is deploying flash for their frequently accessed data. Thin provisioning allows users to effectively double the flash capacity available for this “hot” data to be placed, further improving performance, without any additional effort on the database administrator’s (DBA’s) behalf.

Often, PCIe-based flash cards include built in compression engines.  By default, the compression engines are performing lossless compression on the data sent from the host to reduce the physical writes to the NAND.  As a result, there is actually free space available on the NAND even after the drive appears full to the host.  With thin provisioning enabled, the flash technology can expose this free space to the host as additional usable capacity.  As a result, the thin provisioning can expose up to 2x its rated capacity as logical capacity.  As the compressibility ratio of the data changes over time, the exposed space will dynamically adjust, hence the Dynamic Logical Capacity technology name.

For example, a database application sends 800GB of data to a 800GB PCIe-based flash card and the card appears full. However, the data was 2:1 compressible, meaning that only 400GB of NAND was physically consumed to write the 800GB of data.  The card still has 400GB of available space.  With thin provisioning enabled, the application can communicate with the PCIe-based flash card to store more data in the same available capacity.  With 2:1 compressible data, this would result in the application being able to write 1.6TB of data to the 800GB card.  Utilizing such technology requires close coordination between the PCIe-based flash card and the application. 

Deploying PCIe Flash Based Technology with DLC enabled utilizing Flashcache

When implementing PCIe flash into a MySQL and Oracle Linux environment, decisions have to be made on how to utilize the flash storage. Do you:

1. Convert all of the database objects to flash,
2. Convert parts of the database objects to flash, or
3. Implement caching.

The first two options require DBA involvement with corresponding database downtime during the conversion. Option two requires the DBA to constantly look at database objects that are frequently accessed hot data, to update where the database objects reside: traditional hard disk drives (HDD) or on the flash technology.

If the datacenter wants little or no DBA involvement, automatic data tiering with no database changes, then implementing Facebook’s Flashcache caching module for the Oracle Linux is a good fit. What is Flashcache? Here is a quote from Facebook describing Flashcache:

“Flashcache is a simple write back persistent block cache designed to accelerate reads and writes from slower rotational media by caching data in SSD's. We built Flashcache to help us scale InnoDB/MySQL, but it was designed as a generic caching module that can be used with any application built on top of any block device. For InnoDB, when the working set does not fit in the InnoDB buffer pool, read latency is significantly improved due to caching more of the working set in faster media, such as SSD's. We also improve write performance by first caching writes in SSD's and lazily flushing the data back to disk.”*

Benefits of Implementing both Nytro DLC on Oracle Linux and Flashcache:

By implementing Seagate’s version of Flaschcache with imbedded Nytro DLC on Oracle Linux, the Flashcache caching technology can now take full advantage of the expanded benefits of Seagate PCIe flash storage:
  • Expose up to 2x of the PCIe-based cards rated capacity as logical capacity
  • Higher cache hit rates and fewer latency spikes associated without requiring physical reads from HDD to retrieve the data
  • Lower effective cost per GB
  • Improved GB / Watt
  • Flashcache is a proven caching technology for the InnoDB storage engine in MySQL; and it supports Write-through, Write-around and Write-Back caching options.

For more information about this technology please visit Seagate's Nytro and Oracle Linux websites.

FRIDAY SPOTLIGHT: Getting Started with Docker on Oracle Linux

Happy Friday everyone! 

We have a great technical article for you this Friday.  In this article, you learn how to customize a Docker container image and use it to instantiate application instances across different Linux servers. This article describes how to create a Dockerfile, how to allocate runtime resources to containers, and how to establish a communication channel between two containers (for example, between web server and database containers). 

Ginny Henningsen quotes "Docker is exciting because it can easily capture a full application environment into a virtual container that can be deployed across different Linux servers. System administrators and software developers are learning that Docker can help them deploy application images on Linux quickly, reliably, and consistently—without dependency and portability problems that can inject delays into planned deployment schedules. Docker containers can define an application and its dependencies using a small text file (a Dockerfile) that can be moved to different Linux releases and quickly rebuilt, simplifying application portability. In this way, "Dockerized" applications are easily migrated to different Linux servers where they can execute on bare metal, in a virtual machine, or on Linux instances in the cloud. "

As shown in Figure 1, Docker containers consume fewer resources than "heavyweight" hypervisor-based solutions. Hypervisor-based solutions host a full-blown operating system instance in each virtual machine guest, but this also allows them to support different operating systems. (Oracle VM, for example, can host Oracle Linux, Oracle Solaris, and Microsoft Windows in virtual machines.)

Friday Spotlight: Optimizing Oracle Database Performance on Oracle Linux with Flash

Happy Friday!

This week, I'm dipping into the archives for a really interesting white paper, "Optimizing Oracle Database Performance on Oracle Linux with Flash." It talks about one of my favorite benefits of running Oracle Linux or Oracle Solaris with Oracle database called Database Smart Flash Cache. From the summary of the paper:

"This document explains how to increase Oracle database performance and improve user response time by deploying Oracle’s Flash Accelerator hardware with Oracle’s Database Smart Flash Cache feature. Oracle’s Database Smart Flash Cache feature is supported only on Oracle Linux and Oracle Solaris operating systems beginning with Oracle 11gR2.

The benefits outlined here apply to all Oracle Flash products on Oracle Linux or Oracle Solaris. For this particular study Oracle’s PCIe based in-server Sun Flash Accelerator F40 PCIe Card and Oracle Linux with Unbreakable Enterprise Kernel were used. The findings apply to both the Sun Flash Accelerator F40 and F80 PCIe Cards."

You can read the full paper here.

I also wanted to give a reminder for our webcast next week on Docker. This is a fantastic opportunity to learn not only how to get your feet wet with Docker and Oracle Linux, but you'll also learn the sorts of use cases where Docker really shines from one of our top experts, Avi Miller.

Friday Spotlight: The Power of The Ksplice Feature of Oracle Linux Video

Happy Friday!

I'm really excited to share this week's Friday Spotlight with you. Oracle Senior Vice President of Linux and Virtualization Wim Coekaerts sat down with Director of Product Management Michele Casey and Senior Development Manager Jamie Iles to talk about Ksplice.

In the video, they go into a lot of detail about why Ksplice is a production-ready tool for keeping systems up to date. A highlight for me is the discussion featuring a real world example of an Oracle Linux 6.2 system from 2011, and how a system like that can be patched over time with all the important CVEs and security updates without a single reboot -- no rebooting literally for years. For production systems, you can just keep the system up and running, and still be up to date. Click this screenshot to head on over to Oracle Media Network to watch the video:
