DB2 for z/OS Performance Tuning: the Rising Tide and the Home RunI've been working with DB2 for z/OS for about 25 years. During most of that time, I've been actively engaged in performance tuning work -- specifically, performance tuning as it pertains to the CPU and elapsed time associated with application access to data in DB2-managed databases. I've learned that the best results, in terms of efficiency and throughput gains, are achieved via a two-pronged approach that I conceptualize as a rising tide and home runs. In this blog entry, I'll explain these...(Read more) |

Isolate Applications Within an IBM® DB2® pureScale® Group Using Optim Configuration ManagerIntroduction:
IBM® DB2® pureScale® (also known as DB2 application cluster transparency) feature introduced clustering technology to DB2 on distributed platforms, so you can deploy continuously available and scalable database clusters. The technology is based on the IBM DB2 for z/OS® architecture that businesses worldwide trust for their most critical systems. IBM InfoSphere® Optim™ Configuration Manager for DB2 for LUW V3.1 (OCM) includes the following capabilities for IBM DB2 pureScale® feature:
Although there are many capabilities in OCM V3.1 for IBM DB2 pureScale® feature, this blog entry focuses on the isolate application transactions capability (#6 in the above list).
Isolate Application using Optim Configuration Manager: Isolate applications on DB2 pureScale capability allows DBAs to isolate application workloads to certain members of a DB2 pureScale group. This capability is invaluable for enterprises when they want to:
I’ll use an example to describe this capability, the figure below shows the application “A” and “B” running on against a DB2 pureScale group. DB2 pureScale member “2” has been identified as the member on which isolated applications will execute (penalty box). Misbehaving applications can be identified by IBM InfoSphere Optim Performance Manager for DB2 for LUW (OPM). In the example, application “B” is the misbehaving application and as a result the resources available to application “A” are impacted. The mission critical application “A” therefore has poor response times and the effect cascades to any other applications running on the DB2 pureScale group.
OCM can be invoked from the OPM dashboard. You can define and use client rules in OCM to control applications connecting to DB2 for LUW servers. Additionally, rules can be used to control drivers, data sources, and transactions of user applications and the connections to DB2 for LUW servers. You can create client rules for managed clients only. Managed clients are those clients on which IBM InfoSphere Optim Data Tools Runtime Client is installed. Before you create a rule, you first need to create a rule set, which is a named group of rules. A rule with “Isolate application transactions” type can be defined which isolates a resource-consuming application on DB2 pureScale to a restricted environment so that other applications can obtain the resources they need to perform optimally. This rule moves an application, a group of applications, or a workload within an application to a pre-configured location alias (penalty box) of a specific member in a DB2 pureScale.
Steps to isolate an application to specific DB2 pureScale member(s) in Optim Configuration Manager: The following steps are not comprehensive; I’ve attempted to highlight the steps involved in isolating an application. Step 1: Setup up a location alias for members in a DB2 pureScale group For a DB2 pureScale group, you can define or update DB2 pureScale aliases using a DB2 call to the SYSPROC.WLM_CREATE_MEMBER_SUBSET stored procedure. For example to create a location alias called MY_PBOX for DB2 pureScale member ID 2: CALL SYSPROC.WLM_CREATE_MEMBER_SUBSET( 'MY_PBOX', '<memberPriorityBasis>equalPriority</memberPriorityBasis> <databaseAlias>PBOX</databaseAlias>', '(2)' )
A location alias represents one, a subset, or all members of a data sharing group. The following screen shot shows location aliases ALIAS1 for DB2 pureScale member ID 1, ALIAS01 for DB2 pureScale member ID 0 and 1, and PBOX for DB2 pureScale member ID 2.
Step 2: Define a rule set and a rule within the rule set To create or update a rule set, choose Open > Rule Set Manager. Create a new rule set by specifying a connection, name of the rule set and any comments.
Create a rule in the rule set. The following screen shot shows the rule called “PBOX” in which an application connecting to DB2 pureScale is identified by a condition. Multiple conditions can defined and joined using AND operator to identity the application to be isolated.
After adding the rules in the rule set, save the rule set.
Step 3: Activate the rule set Activate the rule set. Once the rule set has been activated, OCM directs new connections to the DB2 pureScale members identified by the location alias “PBOX”.

New book: Patterns of Information ManagementA couple of years ago, an author who I’ve worked with on a few projects, Dan Wolfson, introduced me to his friend Mandy Chessell who was interested in writing a book. A few months later, Mandy was in Toronto and we met to discuss her book. She told me that it was based on work that she was doing with her clients and that many of her clients were very excited to get their hands on this book. Mandy showed me the work that she had already completed and I was astounded at the level of completeness and quality that she had already put into the book. I introduced her to the people at IBM Press and the book was accepted and after much more work... the book is complete and will publish next week! I’m looking forward to getting my hands on the book and intend to read it cover to cover. Here are details about the book, Mandy, and her co-author Harald Smith. Patterns of Information ManagementBy Mandy Chessell, Harald Smith
Use Best Practice Patterns to Understand and Architect Manageable, Efficient Information Supply Chains That Help You Leverage All Your Data and Knowledge
In the era of “Big Data,” information pervades every aspect of the organization. Therefore, architecting and managing it is a multi-disciplinary task. Now, two pioneering IBM architects present proven architecture patterns that fully reflect this reality. Using their pattern language, you can accurately characterize the information issues associated with your own systems, and design solutions that succeed over both the short- and long-term.
Building on the analogy of a supply chain, Mandy Chessell and Harald C. Smith explain how information can be transformed, enriched, reconciled, redistributed, and utilized in even the most complex environments. Through a realistic, end-to-end case study, they help you blend overlapping information management, SOA, and BPM technologies that are often viewed as competitive.
Using this book’s patterns, you can integrate all levels of your architecture–from holistic, enterprise, system-level views down to low-level design elements. You can fully address key non-functional requirements such as the amount, quality, and pace of incoming data. Above all, you can create an IT landscape that is coherent, interconnected, efficient, effective, and manageable.

Big Data Sessions at IBM Innovate ConferenceIBM Innovate 2013 is a Technical Summit that provides insights that you need to stay ahead..... and it takes place June 2 - 6 in Orlando Florida.
This Summit offers over 450 outcome-driven sessions, including quite a few that are focused on the ever popular Big Data area. If you are attending the conference, you should consider attending these Big Data sessions:
BD-1962 : Agility in a Relational Database World - Dynamic Schema with JSON and DB2
Speaker: William Bireley, IBM
Today's mobile, social, and analytic applications demand agility, speed, and scalability using a flexible data model. This partly explains the huge interest in NoSQL databases. Modern applications frequently need to add, drop, or modify fields in the data store without administrator involvement. Change management processes associated with relational databases can be an impediment to continuous integration processes. A popular NoSQL approach is the use of a "document database", where documents are stored with a flexible format, such as JSON. Many existing NoSQL solutions offer these advantages, but sacrifice "ACID" characteristics of a traditional database, such as transaction control, recover-ability, and other aspects taken for granted in DB2. Using DB2 as a JSON document store provides the best of both worlds. This session describes a solution that does exactly that. The session also includes a live demo showing the power and flexibility of this JSON over DB2 solution.
BD-2501 : Big Data Predictive Analytics
Speaker: Mike McRoberts, IBM
Learn about the new Big Data feature in IBM SPSS Modeler and how to automate and integrate this capability into your application. You don't have to worry about Map/Reduce programming to take advantage of predictive analytics on Big Data.
SC-2486 : Cloud and DevOps: Big Demands, Big Iron
Speakers: Phil Murphy, Forrester; Hayden Lindsey, IBM
DevOps is changing how software is delivered, but how does it fit into your shop? The demands of delivering applications across mobile, social, big data, and cloud technologies are driving development teams to use many different types of technology. Furthermore, Agile methodologies are enabling development teams to deliver usable application features on quicker schedules. This is now happening for application development on all platforms, in private datacenters and public clouds. Learn how your organization measures up as Phil Murphy, VP and Research Director with Forrester Research, presents fresh research on the impact of these technology trends on IT organizations. Listen as Hayden Lindsey, IBM VP and Distinguished Engineer, discusses how software from IBM Rational brings agility to all of your development environments, from mobile apps to mainframe environments.
CLD-2185 : Developing in the Cloud? Turning Challenges into Opportunities
Speaker: Todd Moore, IBM
Address the increasing challenges of meeting the requirements of your customers. Reduce the pressures on development to deploy new services. Address the challenges by leveraging technologies that can develop once and deploy anywhere. Maximize the power of the cloud, while streamlining your development processes to include Mobile, Social, Big Data, and Business Analytics. Understand how OpenStack is providing flexibility in architecting your cloud. Learn how OSLC and TOSCA are integral to simplifying and accelerating your development processes. Todd Moore of IBM and Jay Snyder of Aetna Insurance will take you through their experiences on how they enabled their developer community to leverage these leading technologies to effectively deliver interoperable solutions. By the end of the session, you will understand how to take your team's development processes to the next level and be more responsive in meeting the needs of your customers.
BD-2498 : InfoSphere BigInsights Programming Overview
Speaker: Anshul Dawra, IBM
Get the most from your Big Data by developing new applications. We'll cover the popular programming styles for Big Data, including Map-Reduce, HBase, SQL and Hive, Jaql, Pig, and Text Analytics. We'll show how to create new applications from spreadsheets and display the results graphically. Learn how developers and end users can leverage big data with simple yet powerful programming styles.
BD-2499 : InfoSphere Streams Programming Overview
Speaker: Pete Nicholls, IBM
Big Data is everywhere we look. In late 2012, IBM conducted an audited benchmark illustrating how IBM Platform Symphony delivered a dramatic 7.3 times performance gain across a range of representative Hadoop MapReduce workloads. While the performance results are compelling, for many organizations the real value lies in associated opportunities for cost savings that arise from greater efficiency and resource sharing on a multi-tenant grid infrastructure. In this session, we will explain the benchmarks and results, detail the technologies that enabled the results, and discuss how organizations can take advantage of low-latency scheduling and new file system technologies to achieve dramatic efficiency improvements in their own Big Data projects. IBM will also unveil a total cost of ownership calculator that can help organizations estimate cost savings opportunities for a variety of distributed computing workloads including Hadoop MapReduce.
BD-2510 : Lightning fast access to Data with IBM Caching
Speaker: Brian Martin, IBM
Traditionally, data is placed in storage and when needed, accessed and acted upon in memory. This results in a natural bottleneck that impacts performance. As data volumes increase, the time required to access and analyze grows and becomes cumbersome. Complex calculation can't be accomplished in real time. With in-memory computing, we can better understand how data is shaped and stored. In this session, we will discuss how in-memory data grids like WXS & XC10 mark an inflection point for enterprise applications, especially with big data. Real-time information provides decision makers with insights not previously available. The session will cover how large data sets can be made available and accessed near-instantaneously.
BD-2511 : Test Data Management in the New Era of Computing
Speaker: Swati Moran, IBM
Big data means high volume, variety, velocity and veracity data. Most development and testing organizations aren't prepared to develop and test applications in this high pressure environment. Clients demand access and high availability. In the rush to meet growing client needs and build applications to support the speed of business, testing becomes even more critical. This session will explore best practices for test data management in the software development lifecycle to satisfy the demands of big data, while protecting sensitive data. In addition, it will explain how to speed delivery of big data applications while reducing cost by enabling testers and developers to access and refresh test data.
BD-2049 : Three Steps for Securing Big Data Environments - Why Big Data Doesn't Have to Mean Big Security Challenges
Speaker: Kimberly Madia, IBM
The ability to harness big data has opened the door for world-wide collaboration in real time. Organizations are able to process data on an extreme scale to derive maximum value. However, as big data environments ingest more data, organizations will face significant risks and threats to the repositories containing this data. Failure to ensure data security reduces confidence in decision making. Ironically, organizations are generating more data now as compared to any other point in history, and yet they don't understand how to protect it. In this session, we will discuss three steps to improve security in big data environments.

Participate in DB2 CommunitiesThere are several communities built around DB2 that many people are participating in. It may not be clear which is the best community to be involved with. We had a discussion with several people at IDUG last week and the discussion went into the pros and cons of forums. I personally do not use forums, but am involved with the other communities listed in this post. Read through and share your thoughts on the topic with me and others.
There are many facebook pages that are managed by IBM and are focused on a particular product. I don’t think there is a danger in following all of these pages since the way facebook works is not all of the pages you follow end up in your newstream. Instead, some are, but most are put into a different section and you must click on “page feeds” from your main FB page to see the postings. Here are a few Facebook pages that you may consider following:
LinkedIN is a very popular business connection website. Besides keeping your career details on the site, you can join a huge number of groups to connect with others on a topic that interests you. One of the things I really like about LinkedIN groups is that they send a digest of the activity that is happening in the groups. This can save a lot of time as it takes only seconds to browse the updates. The other thing I like about LinkedIN is the reach. I know more people who are NOT on Facebook than are NOT on LinkedIn. Some groups you may consider joining:
Others
IDUG, ChannelDB2.com, Google+, and developerWorks all have communities that are used by DB2 professionals.
IDUG.org has discussion groups and forums that are apparently widely used. I don’t use them, but I think very technical people do.
ChannelDB2 has over 5000 members, but I don’t find that the groups get used to the extent that they could.
Google+ is relatively new. We started a group there for a specific project and found that most of the members we wanted to join us didn’t have a google+ account yet. I must say I was impressed by the tools, but it may take more time to catch on.
developerWorks is widely known for technical content such as articles, tutorials, and blogs. It is built on the IBM Connections software which has a rich set of tools for wikis, forums, and profiles. I think there is huge potential for this, but again, the community part of it is relatively new.
How you can contribute
Social media is all about sharing information. You can add content to any of these communities as you see fit. Add a link to some content, make a comment about the content that is posted, say that you like the post, or share across your network. Make your opinion heard!
Is anything missing?
What do you think? Are there other communities where you go to for information? Are you happy with the communities that are available? What would you improve if you could?
I’d love to hear what you think... so drop me a comment!
