General Page
Db2 for i is a member of IBM’s family of Db2 databases. What makes Db2 for i unique is its integration with the platform, the IBM i operating system and Power Systems. This unique integration means you do less managing of your database, and more building of applications for analytics, mobile, cloud, or day to day operational purposes. Db2 for i’s open standards support allows you to leverage the world of development tools while protecting your investment in legacy applications. Self-managing is what Db2 for i is all about!
- Built in efficiencies -- Db2 for i is built into the operating system. Open standard support including ANSI standard SQL, XML, JSON, node.js and more provide a multitude of development environments for application development.
- Data that is secure -- Db2 for i contains a rich set of security features and services that pertain to the goals of authentication, authorization, integrity, confidentiality, and auditing.
- Analytics -- Db2 provides many features to support analytical applications. The world class SQL Query Optimizer, Encoded Vector Indexes, and parallelism are just some of the technologies for processing large, complex queries.
- Modernize your database – Flexibility, performance, development productivity, data integrity and security -- a database modernization process that is minimal cost and avoids disruption.
Benefits
Self-configuring
Db2 for i requires limited configuration work prior to use. Using the unique Single Level Storage concepts of the system, database management tasks such as creation and monitoring of table spaces or complex partitioning of data across disk subsystems are not required. Db2 for i provides automatic data spreading and automatic storage allocation for all database objects.
Self-healing
Db2 for i contains a number of self-healing features:
- Systems Managed Access Path Protection (SMAPP) automatically journals (logs) high risk indexes.
- Self-managed journal receivers allow the system to automatically monitor the capacity of a journal receiver.
- Automatic restart of journal processing after a copy or restore operation.
- Index rebalancing is handled automatically and Db2 will also automatically rebuild catalog views eliminating the need for manual intervention.
Self-tuning
- Auto tuner that auto adjusts resources to accommodate changing workload characteristics.
- Cost-based query optimizer which contains advanced query rewrite techniques.
- Automatic detection of changes to the database allowing the optimizer to rebuild query plans without user intervention to maximize performance.
Self-protecting
Db2 leverages the object-based structure of IBM i self-protecting attributes that are built into the operating system:
- Row and Column Level Access Control
- Digital signing of objects to help prevent unauthorized access
- 128 bit data encryption and SSL
- US Government C2 security compliance including object auditing
In addition, the operating system and Db2 for i include built-in encryption capabilities that enable customers to add an extra-layer of security around their data.
