Role of the DB2 Database - Moving Forward

Brought to market in 1983 by IBM for utilization on its mainframe operating systems, DB2 is now a multi-platform object-SQL database management system: 1- mainframe z/OS, z/VSE, z/VM, 2- client/server UNIX, Linux, and Windows servers, 3- iSeries, and 4- IBM InfoSphere Warehouse editions. IBM's DB2 databases have broad utilization by Fortune 1000 companies and the government public sector.

There are efficiencies in storage and productivity associated with DB2 as it scales to increased volume. Deep compression improves response time and query performanceand storage capacity, while increasing the amount of data in the data buffer pool. STMM: Self-tuning Memory Manager automates the configuration, monitoring, and tuning of the system memory in relation to workloads. HADR: High-availability Disaster Recovery decreases the time for recovery from partial and complete site failures. Multidimensional clustering enhances third party enterprise resource planning applications.

The versions of DB2 being upgraded are:

DB2: Version 8 DB2: Version 9 DB2: Version 10 DB2: Version 11 DB2 Version 12

IBM is promoting its SOA: service oriented architecture for updating and integrating existing investments in legacy programming languages and mainframe system software. The SOA and DB2 also will accommodate open source software and third party databases.

DB2 Versions

IBM DB2 Version 10 improved systems performance and provided better information to the optimizer for query types, and processing of INSERT, UPDATE, and DELETE statements. The DB2 Utilities Suite is comprised of DB2 Administration Tool for z/OS, DB2 Object Comparison Tool for z/OS, DB2 Recovery Expert for z/OS, and DB2 High Performance Unload for z/OS. Database management capabilities have been added. The online schema can be used for adding partitions and changing data definitions with ALTER statements and online unload and replace. There are database design options for indexes, clustering, and materialized query tables to rotate partitions which support data warehouses.

SYS-ED workshops demonstrate and explain:

  • Data types for decimal floating point and spatial data.
  • Built-in function compatibility within the DB2 family and for third party and open source databases.
  • XML functions for Java and web applications.
  • Java Universal Driver.
  • How to use REORG for improved performance and availability.
  • New partitioning, clustering, and index options.
  • Dataset level Flashcopy support for multiple utilities for improved CPU utilization and reductions in elapsed time.
  • zIIP-enabled RUNSTATS to perform page-level and auto-sampling rates.

Workshops incorporate IBM product enhancements: 1- Standards-based capabilities for SOA: service oriented architecture requirements. 2- Improved SQLJ and JDBC support. 3- UNICODE support. 4- WebSphere integration.

Big Data and Apache Hadoop

Big Data refers to large volumes - petabytes of data and emerging software technology such as Apache Hadoop and analytical databases. Apache Foundation Hadoop is an open source framework used to store unstructured and multi-structured data. Hadoop runs on commodity servers and provides a low cost staging and refining area for data exploration and reuse. Apache projects being developed as part of an Apache ecosystem include Flume, Hive, HBase, Pig, HCatalog, Mahout, MapReduce, Oozie, and Squoop. Hadoop uses a permissive open source license; it represents a new source of data and opportunity for IBM to drive revenue from DB2 and other new products. IBM has started offering products in conjunction with Hadoop to meet the operational requirements of mainstream business operations. This includes web server logs, system logs, social media, semi-structured data, sensor data, email, and XML: extensible markup data.

IBM SOA: Service Oriented Architecture

Service oriented architecture functions both as a software development environment and a delivery framework. It provides a mechanism for defining business services and operating models as an information technology infrastructure that can be used to meet enterprise business requirements and modernize legacy environments.

In a SOA environment, network nodes make resources available to other network participants as independent services, which participants can access in a standardized way through well-defined service interfaces. SOA is constructed as a shared network of web services linked by distributed intermediaries. Incremental SOA for a mainframe environment will result in a services network. Successful execution of an SOA strategy, combined with the release of the business value contained in legacy systems, DB2 databases, and WebSphere MQ middleware can produce significant value and return on investment by leveraging existing software assets to create new applications and provide interoperability with modern web-based systems.

The principles underlying a service oriented architecture in an IBM mainframe environment include: 1- Reducing implementation costs with a more flexible infrastructure. 2- Reusing applications to reduce development costs. 3- Quality assurance. 4- Simplifying data sharing and information access. 5- Streamlining and modernizing internal operations.

DB2 and Oracle SQL and PL/SQL

Starting with DB2 version 9.7, IBM supports Oracle SQL and PL/SQL. IBM has aligned the syntax and semantics with the locking mechanisms, data types, SQL, procedural language residing on the server, and the client interfaces used by the applications.

IBM has resolved the concurrency control with Oracle by reading the currently committed version of the changed row and retrieving the locked row from the log. In most cases, since the change has not been committed, the row will still be in the log buffer. However, even if the row has been written out and overwritten in the log buffer, DB2 will know exactly where to find it. The single I/O will bring the required version into the bufferpool. Additional lock avoidance techniques have been added which eliminate a reader holding a lock under CS isolation.

DB2 supports a library of functions compatible with Oracle for operating on data. Mismatched types or mismatched semantics of the types can seriously impact the ability to enable an application to another RDBMS. In order to allow Oracle applications to run on DB2, a number of data types commonly used in Oracle's PL/SQL have been added in DB2 9.7. When an application is ported from one product to another, the SQL and procedural language is translated from one SQL dialect to the other. The DB2 engine includes a PL/SQL compiler along with the SQL PL compiler. Both compilers produce virtual machine code for DB2's SQL Unified Runtime Engine.

DB2 Training by SYS-ED

SYS-ED courses and training programs teach the DB2 architecture and components used to implement data integrity and develop systems which are scalable, run in the cloud, and support mobile devices. SYS-ED collective experience with DB2 reflects our knowledge with the underlying design of IBM DB2 Enterprise Server Edition and the foundation development languages that DB2 was written in. The DB2 courseware, examples, case studies, and examples provided in SYS-ED distance-learning and classroom training services is highly respected. The sample programs and exercises were developed to teach DB2 on multiple platforms. The principles of adult learning have been applied to the subject matter: interpreting and translating content into performance objectives, narrative descriptions, and diagrams which explain. The full complement of training medium is used to help business and information technology professionals learn.

When information technology professionals leave a SYS-ED DB2 course, they have the documentation, training aids, and examples to code and debug DB2 programs, perform administrative tasks, and optimize system performance. Case and point, if your organization outsourced its DB2 coding and program maintenance to consulting companies in the 1980ís, it more than likely was SYS-ED which trained many of the consultants who did the actual design and coding.

Few software or consulting companies know and teach DB2 courses better than SYS-ED.

Qualifying a Training Assignment

SYS-ED will not accept a DB2 assignment without a consultation with the prospective client organization. We review the background of the employees to be trained, operating environment, documented standards, and project specifications and use that information to select the code snippets, examples, skeleton programs, and hands-on exercises. We then prepare a training strategy: lesson plan, modular courseware, training aids, and validation assessment. The pre course consultation allows us to identify and differentiate between teaching an industry standard course as compared to the clientís true need for educational consultancy: 1- DB2 database administration on z/OS - mainframe or a specific UNIX-variant, Linux-variant, or MS Windows platform. 2- Integration with WAS: WebSphere Application Server or alternative third party commercial and open source web server platform. 3- Evaluation for migration to IBM service oriented architecture standards. 4- Composite application development and repurposing with Rational Developer for System z. And when not confident that a professional training outcome can be provided politely will turn down an assignment.

As part of presenting an instructor-led DB2 course at the client location, courseware is organized for future use in a web-based infrastructure and delivery medium.

Courseware for Teaching

The courseware used in SYS-ED courses consists of student handouts, training aids, and industry-specific examples and exercises. The CETi knowledge base aggregates and analyzes information in the public domain. It also is a service for reviewing and answering questions. Content is selectively added to courseware. Our long-term strategy is to have our courseware recognized as a NRV: Nationally Recognized Vendor.

The schedule on our websites reflects a projected time frame for licensure with the New York State Department of Education - Bureau of Proprietary School Supervision and submission and approval of curriculum. It will be updated quarterly.

News for Immediate Release

Consulting companies recommend SYS-ED in conjunction with distance-learning for DB2 programming, database administration, and web enablement training and programmer training on selected topics.

DB2 Application Development and Web Enablement Training Program

All IT personnel will need to learn new skills for the z/OS environment in order to implement the next generation of technologies - DB2, WebSphere MQ, WAS, and Rational. Training will cut across generations - some very experienced people will be learning web enablement technologies; while first generation IT staff will be using ISPF, JCL, and ďtried and testedĒ mainframe programming languages, such as COBOL for the first time. Training programs based upon the use of various training techniques have been chosen for suitability to the particular course material and audience as well as scheduling and class size requirements.

The following methods will be used for introductory material for personnel, mo

Program for Client A
  • Distance-learning will be used for introductory training for personnel, most operator training, and programmer training on selected subjects.
  • SYS-ED will be used for their 3-day DB2 Stored Procedures, 4-day DB2 Java Programming, 4-day DB2: Systems Performance and Tuning, 4-day WebSphere MQ System Administration, and 4-day WAS: WebSphere Application Server courses.
  • IBM Education Center offerings will be used for specialized operations training.

The plan is to have the entire programming staff and four or five people from operations complete the distance-learning training and then take the SYS-ED instructor-led courses. Based upon feedback from this group, we will either confirm this mix or make adjustments as needed.

On a long range basis, we plan that all of the programmers and operators will be trained in both z/OS and the new web technologies. The exact schedule will depend on the other workloads of the staff. System programmer education would be mostly completed during this period, although specialized courses may be taken later in the year.

Evolving IT - Interrelated Technologies

Information technology training for organizations is more complex and challenging than ever before. There is a substantial investment in infrastructure and applications specific to their operations. New industry standard protocols, web server and web enabled technologies require development from scratch or integration with the existing system software and enterprise databases. There will be long term implications regarding the strategic mix of commercial and open source software which is selected, along with decisions on whether to maintain and upgrade the existing legacy applications, while retrofitting and transitioning to the new technologies. SYS-ED trained a significant portion of the first generation of DP personnel. And looks forward to training their IT successors in the 21st century.
