Figure 58. DB2 PM Accounting, SQL DML Section

The DB2 PM accounting report contains two more sections with SQL statements. One of these (SQL DCL) contains interesting information for this study. This section is shown in Figure 59 on page 143:

LOne SET DEGREE statement

MOne CONNECT of type 2

The SET DEGREE statement means that the user decided to enable parallelism for this query. This can be confirmed by examining the parallel query section of the DB2 PM accounting report in Figure 60 on page 143. A parallel degree of 5 (N in Figure 60) was established. One parallel group executed (O in Figure 60) and it executed with a degree of 5 (P in Figure 60).

The other DCL statement (M in Figure 59 on page 143) is a CONNECT of type 2. This could mean that distributed data was accessed. To confirm this, the DDF requester information in the accounting report is checked, this section is not present in the report. Statistics also collects DDF information, this is shown in Figure 61 on page 144. No information is shown. This means that the trace classes to collect DDF information were not started, or there was no DDF activity.

5695-DF1, 5655-DB2 specifications

IBM 5655-DB2 and 5695-DF1 are significant components within the IBM software ecosystem, predominantly focusing on data management and integration solutions. These offerings cater primarily to enterprise environments that require robust database management systems and associated frameworks to maintain and manipulate data efficiently.

IBM 5655-DB2 is a well-known relational database management system (RDBMS) that excels in managing large volumes of structured data. Its architecture is designed to support high availability, scalability, and performance, crucial for businesses operating in today’s data-driven world. Some of its main features include advanced indexing capabilities, support for complex queries, and dynamic workload management. Additionally, it provides strong concurrency controls, which enable multiple users to access and manipulate data simultaneously without compromising data integrity.

One of the key characteristics of DB2 is its support for various data types, including JSON and XML, making it versatile for modern applications that generate data in diverse formats. It also features robust security mechanisms to protect sensitive data, aligning with compliance standards across industries. Integration with analytics tools further allows businesses to derive insights from their data, enhancing decision-making processes.

On the other hand, IBM 5695-DF1, also known as the InfoSphere DataStage, is a powerful data integration tool that facilitates the extraction, transformation, and loading (ETL) of data from various sources to target systems. It empowers organizations to streamline their data flows, ensuring that clean, consistent information is available for analysis and operational use. Key features of 5695-DF1 include a user-friendly graphical interface that enhances developer productivity and a rich set of connectors for numerous data sources, enabling seamless data integration.

DataStage also supports real-time data integration, allowing businesses to keep their data synchronized across multiple platforms. Its parallel processing capabilities dedicatedly optimize performance, enabling organizations to handle vast datasets efficiently. It incorporates data quality tools that help in validating and cleansing data before it is used for decision-making processes.

Both IBM 5655-DB2 and 5695-DF1 are part of a broader strategy to accommodate the evolving landscape of data management. Businesses leverage these technologies to enhance their data architectures, fostering agility and competitive advantage in their respective markets. Their integration capabilities, along with a focus on security and scalability, position them as vital assets in modern enterprise environments. Whether managing critical data within a database or ensuring seamless data flow across systems, these IBM offerings provide a comprehensive approach to handling complex data challenges.
