The Warehouse team has been busy creating yet another best practice paper.
Best practices: Using High Performance Unload (HPU) as part of a Recovery strategy
IBM InfoSphere Optim High Performance Unload (HPU) for DB2 for Linux, UNIX, and Windows V4.2 is a high-speed tool for unloading, extracting, and repartitioning data in DB2 for Linux, UNIX, and Windows databases. HPU unloads large volumes of data quickly by reading directly from full, incremental, and delta backup images or table space containers rather than through the DB2 software layer.
The database is not affected by the HPU process and table spaces do not need to be placed in an offline state. HPU can therefore offer advantages over other recovery methods in data availability and processing speed. Incorporating HPU into your recovery strategy for scenarios involving data loss or corruption can help achieve service level objectives for data availability and data recovery.
Incorporate InfoSphere Optim HPU into your recovery strategy to provide:
- Reduced recovery times through targeted data recovery
Use the WHERE clause when selecting data from backup images to target only the data that was lost, compromised, or corrupted, reducing recovery time.
- Increased data availability and reduced resource usage during recovery scenarios
Unload data from a backup image and optionally process this data on a non-production system, maintaining availability of the query workload and reducing the effect on the production system.
- Integration with DB2® and Tivoli® Storage Manager (TSM) software
Query TSM to unload data from full, incremental, and delta backup images archived to TSM by the DB2 BACKUP command, reducing errors and facilitating outside recovery.
This article discusses how to incorporate HPU into a recovery strategy and when to use HPU to meet your recovery objectives. In addition the authors contrast the use of output files and named pipes, discuss introducing parallelism, review the HPU command and control file, and recommend best practices for creating control files. Finally, the article details how to install and configure HPU in an IBM Smart Analytics System.
This paper will be followed in the new year with a second paper on HPU that deals with data migration.
Thanks to the hard working team that includes: Garrett Fitzsimons, Konrad Emanowicz from the VLDB team who created and tested all the scenarios discussed in the paper and to Richard Lubell from the DB LUW ID team who steered the paper through to publication. Thanks also to Alice Ma, Austin Clifford, Bill Minor, Dale McInnis, Jaime Botella Ordinas, and Vincent Arrat whose contributions, feedback and experience were invaluable.
Thanks to Garrett and Serge for providing me with this information.

Congratulations to the Best Practices team for putting out another excellent paper. This one is for Workload Manager: DB2 best practices: Implementing DB2 workload management in a data warehouse
What You’ll Learn:
- The best ways to implement a successful workload management solution using DB2 for Linux, UNIX, and Windows, Version 9.7.4 or higher.
- The information in the article reflects the latest experiences of IBM field personnel and customers within the data warehouse arena.
Using a staged approach, this article guides you through the steps needed to implement the best practices workload management configuration on IBM DB2 for Linux, UNIX, and Windows with sufficient controls to help ensure a stable, predictable system for most data warehouse environments. This initial configuration is intended to be a good base for implementing additional tuning and configuration changes as needed, in order for you to achieve your specific workload management objectives.
You’ll be presented with a set of definitions representing the different stages of maturity for a workload management configuration in a DB2 for Linux, UNIX, and Windows database. These stages range from stage 0 through to the advanced stage 3 configuration. A specific configuration template and process is provided as part of these best practices to enable customers to progress from a stage 0 configuration to a stage 2 configuration. General descriptions and advice are also given about common stage 3 scenarios.
The article assumes a novice beginner and describes the individual steps and mechanisms at each point. A more experienced user can condense many of the listed steps to move from stage 1 to stage 2, making the transition in days of elapsed time rather than weeks as the suggested timeline indicates in a later section.
The steps outlined are focused on the efficiency of the system as a whole, regardless of where the work itself comes from. It is important to note that achieving the goal of a stable system might not necessarily also result in the achievement of any individual application service-level agreement (SLA) or specific performance objectives for queries. These more granular objectives might require subsequent changes to the workload management configuration, such as outlined in the section on stage 3 scenarios, which is outside the main scope of this document.
This is not a tutorial on DB2 workload management capabilities and does not attempt to provide comprehensive guidance in addressing all possible scenarios where DB2 workload management might be employed. It also does not cover all features within the DB2 product that might be of use in controlling resource consumption. The scope of this article is focused on describing the system stabilization approach in some detail and provides some general guidance for common advanced scenarios.

Sadly I’m not at IDUG this year. I’ll definitely miss many very special people, the education, the networking, and the dine around event. For those of you who are there, let us know how it is going, and get full use out of your visit!
My good friend Kate Kurtz is attending IDUG this year. It is her first time and she is presenting a session. I’ve asked her to guest blog for me while the conference is going on. This is the first of her entries. I hope you enjoy:
My name is Katherine Kurtz, and it is my first time going to IDUG!
Susan invited me to write some guest blogs, to give the inside scoop on the various sessions at IDUG and what the experience is like. I work with a great team of people developing best practices for the IBM Smart Analytics System and InfoSphere Warehouse Environments, and I am currently a manager for DB2 and IBM Smart Analytics System Information Development.
I really believe that we should educate people - ourselves and our customers - about the best way to use our products, which is how I ended up submitting several sessions to IDUG. (Note to self: Be careful what you ask for! Preparation for IDUG was about 5x more work than I expected). Best Practices are all about taking what is tried and tested in the field, putting it together with the future directions our development team is working on and then working together to make a great product even better.
I love what I do - and it is great to always be learning.
It is the night before I leave and I am currently building my checklist.
- presentations ready? check (well - maybe not quite, I think I still want to tweak a few things)
- packed? check
- American $$ , just in case I get to go shopping... :-) check
What will I be doing while I am at IDUG?
I have two sessions I am co-presenting. Warehouse Best Practices In Action - The IBM Smart Analytics System and also Best Practices for Building a Recovery Strategy for your Data Warehouse. I was also asked to participate in a Special Interest Group panel discussion, focusing on Data Warehousing. I am sure there will be lots of interesting debate - and I hope I can think on my feet! There is also the first timer luncheon on Wednesday - where I get to go as an IDUG first timer and as an IBMer, plus I get food, which is always a good thing.
One of the things I liked the most about IOD last fall (which was also the first time I attended IOD) was the conversations I had with customers I met during different sessions. It was always interesting to hear their point of view, and I think it really changes the way I think about the products that we are developing. I hope IDUG will be the same way - lots of great discussions, and chance to learn a lot from others.
If you are attending IDUG, please be sure to stop by and say hi,
Thanks Kate! Looking forward to hearing more from you.

Summary: Data in a data warehouse can be classified according to its temperature. The temperature of data is based on how often it is accessed, how volatile it is, and how important the performance of the queries that access the data is. Hot data is frequently accessed and updated, and users expect optimal performance when accessing this data. Cold data is rarely accessed and updated, and the performance of the queries that access this data is not essential. Using faster, more expensive storage devices for hot data and slower, less expensive storage devices for cold data optimizes the performance of the queries that matter most while helping to reduce overall cost.
Learn about a strategy for managing a multi-temperature data warehouse by storing data on different types of storage devices based on the temperature of the data.
This article provides guidelines and recommendations for each of the following tasks:
- Identifying and characterizing data into temperature tiers
- Designing the data base in an IBM® Smart Analytics System environment to accommodate multiple data temperatures
- Moving data from one temperature tier to another
- Using DB2® workload manager (WLM) to allocate more resources to requests for hot data than to requests for cold data
- Planning a backup and recovery strategy when a data warehouse includes multiple data temperature tiers
The content of this article applies to data warehouses based on version 9.7 or later of DB2 for Linux®, UNIX®, and Windows®. All examples in the article refer to IBM Smart Analytics System and InfoSphere™ Balanced Warehouse® environments.

Summary: Public cloud computing is an emerging computing technology that uses the Internet and central remote servers to host data and applications. It allows consumers and businesses to use applications without installing them locally and access information from any computer with Internet access. Cloud computing allows for much more efficient computing by using centralized storage, memory, and processing. The benefits of cloud computing are clear, and so is the need to develop appropriate security for cloud implementations.
This article is important for all DBAs who are setting up or managing databases in a public cloud environment. The details and best practices in this article will help DBAs protect themselves and their companies from security leaks and exposures by applying a standard, high-grade security policy to all databases that are hosted in a public cloud.
The information in this article is organized into three main sections:
- The IBM data server security blueprint: The blueprint first positions data server security within the bigger enterprise security picture. This section also describes steps to develop and roll out a security plan.
- Threats and countermeasures: This section describes the most common threats that affect a data server, whether it is deployed in a traditional environment or a cloud computing environment. The section then recommends a set of countermeasures.
- Additional cloud-specific security challenges: This section examines the additional challenges posed to data security in a cloud environment, in particular the need for privileged user monitoring and data segregation.
