What is DB2 “Cancun Release”?

If you’ve been watching social media sites today, you may have noticed a few things mentioned about a new DB2 10.5 release.  There is one that went out today and it has a few names:

  • DB2 “Cancun Release”
  • DB2 10.5 “Cancun Release”
  • DB2 10.5 Fixpack 4

Yes they’re all the same.  The message here is that the fixpack did more than fix bugs, it provided a few new features.  The features are so important that rather than just keep the name as FP4, we added a cool name to bring some attention to it.

The main message for DB2 "Cancun release” is that on top of the powerful features already in DB2 10.5, you now get more:

You can get real-time answers to ALL your questions with instant insight into historical and “as it happens” data with Shadow Tables.  Learn more from this blog from Amit Patel:  Find out what’s new for BLU Acceleration.

Do you run SAP applications with DB2?  Running them in the DB2 "Cancun Release" will bring you superior performance and less disruption to your SAP Environments.  If reporting is key for you, report generation workloads on DB2 on POWER8 will blow you away: tests showed average performance improvement of 82x compared to a competitive database: Learn more: http://bit.ly/WhatsNewCancun

If you work extensively with DB2 and pureScale you’ll love this release! One new thing: You can now perform online table reorgs and incremental backups in pureScale environment.  And the latest release improves ease of use and serviceability of installation, configuration and updates.  Where did all these ideas came from?  From our large DB2 pureScale community.  Yes, we listened!  Learn more from this blog entry from Kelly Schlamb: pureScale at the beach: What's new in DB2 "Cancun Release"?

If you’re coming from an Oracle background, you’ll be happy that it is even easier than before to use your acquired SSQL mastery with DB2.  You’ll find no skills issues if you move to DB2 from Oracle.  The SQL skills you already have are transferable: Learn more: http://bit.ly/SQLCompatability

That’s it for today, but I can give you a hint for the coming weeks:  There are papers, tweetchats, webinars, blogs, graphics, presentations, conference sessions, videos, developerWorks articles, IBMdatamag.com articles, and much more currently in development.  I suggest you follow https://twitter.com/IBM_DB2 for details on all this as we release it.

In fact, let me ask you to do something.  As you go through this information, write down your questions and send them to me or tweet to #ASKDB2.  We’ll gather all of your questions and make sure they are publicly answered.

That good old DB2 catalog poster

pureScale at the Beach. – What’s New in the DB2 “Cancun Release”

Kelly Schlamb DB2 pureScale and PureData Systems Specialist, IBM   Today, I’m thinking about the beach. We’re heading into the last long weekend of the summer, the weather is supposed to be nice, and later today I’ll be going up to the lake with my family. But that’s not really why the beach is on […]

pureScale enhancements included in the new DB2 Cancun Release 10.5.0.4

Today is the day when DB2 10.5 FP4, known as Cancun Release has been published officially!

This DB2 Cancun Release includes many different new features and improvements in differents areas like:

  • Column-organized tables
  • SQL compatibility
  • Monitor elements
  • HADR
  • pureScale

The summary of the enhancements can be found here:

http://www-01.ibm.com/support/knowledgecenter/SSEPGG_10.5.0/com.ibm.db2.luw.wn.doc/doc/c0061179.html

 

There are some exciting improvements and new features included on the pureScale side, which will make even easier to implement pureScale!

  • Support to pureScale over TCP/IP sockets
  • Geographically dispersed DB2 pureScale cluster (GDPC) is extended to support RDMA over Converged Ethernet (RoCE)
  • pureScale can now be deployed on virtual machines using sockets (on VMware ESXi and KVM)
  • Incremental backup support
  • DB2 Spatial Extender support
  • Online (inplace) REORG now supported
  • Federated two-phase commit

Some of these features are really useful to get started with pureScale like having the possibility to run pureScale using just a basic TCP/IP network or using virtual machines under KVM or VMware ESXi. This is great for who wants to explore pureScale technology just using a basic network or a virtualized environment!

But also, for actual pureScale users, two great enhancements like incremental backups and online REORG will be a huge improvement in terms of system and database maintenance and administration.

If you like me are really looking forward to try all these new features, just go and download the just released DB2 Cancun Release 10.5 FP4 at this link:

http://www-01.ibm.com/support/docview.wss?uid=swg24038261

 

Feel free to ask any question or comment you may have on all these new and exciting features for pureScale!

DB2 10 for z/OS, 1 MB Page Frames, and the Number 6656

I recently received an interesting message from a mainframe DB2 person I've known for a long time. At his DB2 10 for z/OS site, 1 MB page frames had recently been made available on the System z servers, and my friend moved to leverage this resource via page-fixed DB2 buffer pools. Nothing unusual there. What's interesting is the information he saw in the output of -DISPLAY BUFFERPOOL commands subsequently entered for the page-fixed pools. I'll get to that strange-looking data in a moment, but...

Have Oracle expertise? Turn it into DB2 skills, easily

Yesterday I published the blog entry NOW is a good time to upgrade to DB2 10.5! and I had a comment asking me how people can quickly upgrade their skills.  The person asking was focused on those who have Oracle skills and now want to work on DB2, but new skills need to be taught to those who are skilled in DB2 9.7 and now need to move to DB2 10.5.  Here is what I suggest:

Three Easy Steps to Learn BLU Acceleration

  1. Step1: BLU Acceleration Technical Deep Dive
    IBM Distinguished Engineer, Sam Lightstone , (1.5 hours)
  2. Step 2: DB2 10.5 with BLU Acceleration free flash book
    New analytics for the era of big data
  3. Step 3:Try it using one of these options 
    BLU Acceleration for Cloud  - OR – 90-day free trial software

My biggest tip:  Be active in social to get the very latest in what is published.  Social channels like blogs, twitter and facebook are used to promote the ever growing list of learning materials.  You’ll find links to white papers, articles, best practices, videos, books, and even formal education.    If you’re on twitter, there is really only one place to follow: https://twitter.com/IBM_DB2  This is the official DB2 account and posts will tell you everything you need to know, including activities generated outside of IBM.  Although IBM produces a ton of great content, we rely our partners, IBM Champions, and IBM Gold Consultants to also publish content about our products.  I’ll do a separate blog post on the incredible learning opportunities provided by our user groups and partners.

We have a dedicated website called ibmbluhub.com that is the go-to place for all things BLU.  My intern Tori McClellan just published her first blog entry about what you can find on the “BLU Hub”: Steps toward the Future: How IBM DB2 is changing the Game.    

DB2 is something like 99% compatible with Oracle.  Danny Arnold does a great job summarizing the areas of compatibility: Simplifying Oracle Database Migrations.  As you are aware, mastery comes through practice.  It may take a bit of habit changing and practice to master the skills you need to be efficient at using DB2, even if the skills are similar.   If time is not your friend, you may benefit by joining a bootcamp session: http://ibm.co/DB2BLUBootcamp.   You may also find this education roadmap useful, especially if you can arrange to have Melanie Stopfer teach a class for you.

 

I hope this helps!  I look forward to more comments and perhaps suggestions on future blog posts.

 

Susan

NOW is a good time to upgrade to DB2 10.5!

Sometimes it can be scary to upgrade software.  Face it, when things are going well, why introduce a change that may put your life into chaos?  We have enough change and stress in our daily lives, is it worth introducing more?  Of course, the answer is, it depends.  What benefits will you achieve? 

Let’s step back a second and think about when you first got your smart phone.  That was a huge change to your routine, most of it fun, but a huge change, nonetheless.  What did you gain?  Access to more, and more, and more.  You can get the latest news on twitter, post a photo on FB, post a review of the restaurant you just ate at, find a parking spot in a normally crowded part of the city, buy movie tickets for the movie you want to see tonight, check out the traffic volume on your normal routes home, find out about a sale at the Costco that you are about to drive past.  And more.  My Dad is still using an old cell phone and asked for help adding contacts.  I can no longer remember how to do that.  It is one of the things that is much easier on a smart phone.

The same goes with a software upgrade.  DB2 9.7 seems to be a very popular release.  At the beginning of Scott Hayes’ DB2 Night Show webinars, he has a polling question about the current release of DB2 that people are using. I almost cry when I see the number of people still at 9.7.  Working for IBM, I’m privy to the latest features of the latest products and in my biased view, buy into the claims that the latest level is so much better.  I’m not the only one that thinks so. 

 

 

Yes, upgrading your software introduces massive changes to your environment, but the benefits of using DB2 10.5 versus older versions is worth the effort, especially when you are able to learn from the experts and minimize your risks.

For added incentive, watch these videos that feature various clients talking about what they discovered after upgrading to DB2 10.5: https://www.youtube.com/playlist?list=LL9QnRdjWEIe58LXKpAoXl4A

DB2 for z/OS: Can a Pooled DBAT Hold Locks?

The answer to the question in the title of this post is, "No, it can't -- unless it can." How's that for a hook? OK, a little background. A DBAT is a database access thread. It's the kind of thread that a network-attached application process uses to interact with a DB2 for z/OS system (such a process, also referred to as a DRDA requester, issues SQL statements that get to DB2 by way of the distributed data facility, aka DDF). When a transaction using a "regular" DBAT completes, the DBAT goes...
