6.2.1 Online Production Databases

The databases used in production normally contain important data and have special availability and security requirements. Performance may become a critical issue, if the databases are used in an online environment.

Because online production databases contain important data, the DB2 Database Administrators typically monitor them very frequently. These databases are sometimes placed on specific disks to manage the data individually. These databases should not be mixed on a disk with other high activity databases or data sets.

6.2.1.1 Storage Classes

The following example Storage Classes can be used for online production table spaces:

SCDBMED

SCDBFAST

SCDBCRIT

6.2.1.2 Management Classes

The following example Management Class can be used for online production table spaces:

MCDB20

6.2.2Batch Production Databases

Most production databases are accessed both in batch and online. In this case, the more restrictive requirement for online databases should be applied to the batch environment. This description applies only to databases exploited in a batch environment.

6.2.2.1 Storage Classes

The following example Storage Classes can be used for batch production table spaces:

SCDBMED

SCDBFAST

6.2.2.2 Management Classes

The following example Management Classes can be used for batch production table spaces:

MCDB20

MCDB21

MCDB22

6.2.3Data Warehouse Databases

Data Warehouse databases contain a special type of production data. Their requirement is normally more oriented to usability and end user access. The end users expects performance to be reasonable (and this is a subjective matter), and the same applies to availability. Some customers run applications in their Data Warehouse environment, and their requirements could become similar to batch or even online production.

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.
