6 IBM US Announcement Supplemental Information September 17, 2002 Additional Information Manageability Health Monitoring Tools: The Health Monitor is a server-side tool that constantly monitors the health of the instance without user interaction. If the Health Monitor finds that a defined threshold has been exceeded, or it detects an abnormal state for an object, the Health Monitor will raise an alert. The Health Center provides a graphical interface to the Health Monitor. It is used to configure the Health Monitor, and to see the alert state of your instances and database objects. Using the Health Monitor s drill-down capability, you can access details about current alerts and obtain a list of recommended actions describing how to resolve the alert. It provides a mechanism to execute some of these recommendations immediately. Web Health Center: DB2 V8 also provides a new Web Health Center that can be used to access the Health Monitor information from a Web browser or PDA, allowing you to execute new DB2 commands. The Memory Visualizer tool helps you to uncover and fix memory-related problems on a DB2 instance. It uses visual displays and plotted graphs to help you understand memory components and their relationships to one another. You can invoke it from a Health Center recommendation, or use it on its own as a monitoring tool. Enhancements to the LOAD Utility and the Load Wizard: Load operations now take place at the table level. Concurrent access to other table objects in the same table space is possible during a load operation, while allowing read access to the table being loaded. A new locking option is introduced in this release that forces applications to release the locks they have on a particular table, allowing the load operation to proceed. In addition, the load utility itself now has a graphical progress monitor to easily monitor progress. There are many diverse configuration options that can affect a load. The Load Wizard groups the options into affected areas such as performance, recoverability, and diagnostics. It then asks questions about each option to help guide the decision-making process to get the most effective result. The wizard also offers advice about how the various options affect the rest of the system and provides space and time estimates. Whether you wish to load data into a single partition, or a large number of partitions across a number of machines, the Load Wizard provides the assistance and direction you need as a database administrator to get the job done right, and in a timely manner. Improvements to Statistics Collection New options for usability (ON ALL COLUMNS, ON KEY COLUMNS, ability to specify individual index names) New statistics for LIKE predicate processing Ability to specify distribution statistics limits at the table and column level Ability to perform sampling for detailed index statistics to improve performance Ability to gather statistics during index creation Online Inspect and Improved Trace Performance: DB2 V8 enhances the customer s ability to examine and diagnose error conditions by delivering a much improved trace facility with greatly improved performance and an online Database Analysis and Recovery Tool (DB2DART). The new trace facility provides very low overhead, high-performance operation that allows customers to have tracing activated in the most demanding production environments. The ability to have trace active in production without adverse effects on operation allows customers to more easily diagnose error conditions without having to engage in off-line problem determination. The online DART tool allows database administrators to verify the integrity of DB2 data on disk without taking the database off-line. Kerberos: DB2 V8 enhances the customer s ability to manage secure access to DB2 data by extending support for Kerberos, an industry-standard authentication protocol. Previous versions of DB2 provided support for Windows Active Directory and Kerberos protocol to allow customers to implement single sign-on solutions in Windows 2000 and z/os environments. V8 extends this support to the UNIX and Linux platforms to provide secure single sign-on solutions across all supported environments. Other manageability enhancements are: Backup and recovery enhancements Enhanced monitoring Tivoli integration For additional details, refer to the Manageability section in the Additional Information section. Information Management System (IMS ) Control Center: IBM provides an IMS Control Center capability as an alternative GUI for the new IMS V8 Operations Manager through IMS Connect, greatly easing IMS operations. The IMS Control Center capability will be integrated with the DB2 UDB V8 administration tools in the near future. A single user interface lets you control both IMS and DB2. The administration tools include a Control Center for navigating IMS Sysplex systems, wizards for creating the new IMS V8 Operations Manager commands, and a results window for sorting and filtering single-system image command results. The tools also include a Command Center for typing and executing both the new commands and the old operations commands. IMS Connect is being enhanced to allow the DB2 Control Center to communicate with the IMS V8 Operations Manager. Additional IMS Connect service stream enhancements include J2EE Connect or Architecture This announcement is provided for your information only. For additional information, contact your IBM representative, call 800-IBM-4YOU, or visit the IBM home page at: IBM United States IBM is a registered trademark of International Business Machines Corporation

7 two-phase commit support, ipv6 support, and enhanced security. Load from Cursor (Cross-Loader): DB2 V8 LOAD command has been enhanced to allow loading from a cursor. This new option can be used to provide high-speed transfer of data from any data source that can be queried with a SELECT statement. For example, data can be loaded into DB2 from a SELECT statement issued against a DB2 for OS/390 table (via DB2 Connect ). By utilizing federated database feature DB2 and full power of SQL, data can loaded from multiple heterogeneous remote databases and data sources. For example DB2 table can be loaded from a join of an Informix Dynamic Server table and data delivered through an MQ message. An additional benefit of loading from a cursor is the ability to complete load operation in a single step without a need for cumbersome export and file transfer steps. MQT Delta Refresh After Load: DB2 has enhanced the support for Materialized Query Tables (MQTs, previously known as ASTs) to enable them to be incrementally refreshed after a load append operation. The MQT will be available during the load operation and once the load operation completes, the data that was appended to the table can be incrementally added to the MQT. AUTOCONFIGURE Command: DB2 V8 introduces a new command that recommends and optionally applies new values for buffer pool sizes, database configuration, and database manager configuration. This command provides initial tuning for a database, to which additional tuning can be applied. AUTOCONFIGURE can also be used with the CREATE DATABASE command to configure databases as soon as they are created. New Storage Management Tool: A Storage Management tool is now part of the GUI Control Center. From this tool you can access the Storage Management view that displays a snapshot of the storage for a particular database, database partition group, or table space. This tool can periodically capture and display statistical information on a variety of storage objects. Use the information displayed in this view to monitor and set thresholds for various aspects of your storage, such as space usage for table spaces, data skew in database partitions, and index cluster ratio. A warning or alarm flag will let you know if a target object exceeds a specified threshold. Logging Enhancements: In V8, dual logging is provided on all platforms supported by DB2 UDB. The maximum amount of log space that can be defined has increased from 32 GB to 256 GB. This provides support for more concurrent transactions and transactions that do more work. DB2 V8 allows an active unit of work to span both active and archive logs. A single transaction can access a number of log files limited only by the total physical storage available across your primary and archive systems. This support for infinite active logs can be used to support environments with large jobs that require more log space than you would normally allocate to the primary logs. The block on log disk full capability allows you to specify that DB2 should not terminate when the log disk runs out of storage. When you enable this option, DB2 will retry every five minutes allowing you to resolve the disk full situation followed by resumption of normal operation. Backup and Recovery Enhancements: DB2 UDB V8 includes several backup and recovery enhancements. During the recovery of a table space, only the log files required to recover the table space are processed. Log files that are not required are skipped, thus improving recovery time. The backup utility now supports backup solutions from storage vendors that have implemented the XBSA industry-standard interface. A database created on a system with one code page can be backed up and then recovered to a system with a different code page. When using point in time (PIT) rollforward recovery, you can now specify the time as local time instead of Greenwich Mean Time (GMT). Rolling forward to a specific point in time is easier, and it eliminates potential errors due to the translation of local to GMT time. Diagnostics and Serviceability Improvements: DB2 V8 places diagnostics information in two distinct log files, depending on its intended use and target audience. When significant events occur that may require DBA intervention, DB2 writes information to the administration notification log. Diagnostic information about database operation errors are recorded in the diagnostic db2diag.log file. This information is used for problem determination and is intended for DB2 customer support. Support for Multiple Fixpacks on a Single System: DB2 V8 will support multiple service (Fixpack) levels simultaneously on the same system. This support is only available with DB2 UDB Enterprise Server Edition on UNIX platforms. Support for multiple service levels allows the testing of a new service level while an older service level continues to support a production environment. Once testing is complete, the production environment can be switched to the new service level. Different applications that have been certified with different DB2 service levels can now be hosted on a single server. Version Identifier for Packages: DB2 V8 provides the ability to support multiple versions of the same package (database object associated with each application) in a single system. This option allows: Multiple packages that share both the schema and package identification to coexist in the DB2 system catalogs Introduction and testing of a new version of an application on the system without affecting users of the existing version of the application Database Maintenance Mode: In quiesced mode, the DBA can control who can access the database and limit database activities to only those authorized users. Enhanced Monitoring: Event monitors can now write data to SQL tables in addition to files or pipes. This provides the following benefits: Storing the data in an SQL table means you can define exactly which data elements you need to keep while discarding the rest. Storing the data in an SQL table makes it easy to prune the data using timestamps or other relational criteria

8 With event monitor data located in tables, users can now query and aggregate data easily using SQL operations. Event monitors that write to tables can capture data on any or all database partitions. By inserting into the same table on each database partition, DB2 delivers global event monitoring across the whole database. Snapshot monitoring can now be done using SELECT statements against a set of new table functions shipped with DB2 V8. Taking snapshots using SQL enables you to retrieve system status data without having to write an application that invokes the DB2 API interface. You can now use all of the power of SQL to filter the data and correlate the different types of snapshot information. Enhancements to the deadlock event monitor assist the DBA in determining why deadlocks occur. The deadlock event monitor now provides more information than it did in previous releases by identifying which statements are involved in the deadlock, and by pinpointing which locks are held by each application involved in the deadlock. Tivoli Integration: DB2 V8 is Tivoli-ready. When a DB2 V8 product is installed, the required signature files are created so that Tivoli Inventory and Discovery can investigate a machine and find DB2. The Tivoli Manager for DB2 is used to manage a variety of database operational activities, including start and stop, recovery, and the monitoring of each server component. Performance and Scalability Enhancements Connection Concentrator: The DB2 concentrator is beneficial in a transactional workload environment where each transaction is of relatively short duration and there is no requirement to use an external transaction manager such as Encina or Microsoft Transaction Server (MTS). Improved Performance of Databases with Multiple itions: DB2 V8 supports caching of system catalog and authorization data at each partition of a partitioned database. These caching enhancements will improve the performance of workloads that perform a great number of dynamic SQL or consist of a large number of database connections that are short in duration, which is typical of some transactional workloads. Improved Performance of DB2 Routines: DB2 V8 routines (stored procedures, user-defined functions, and methods) written in Java language are implemented using a thread-based model that results in a dramatic performance increase when many routines are running at the same time. DB2 routines that are defined as thread-safe will be executed inside a single DB2 task, which will reduce the amount of context switching for users that run large numbers of fenced mode routines. There is one task for all Java routines and one task for all non-java routines. Multidimensional Data Clustering: DB2 V8 marks the introduction of multidimensional clustering (MDC) technology, which is an innovative method for flexible, continuous, and automatic organization and storage of data along multiple dimensions instead of the more common data clustering in a single dimension. Using MDC to organize a table along multiple dimensions such as year and region can result in significant improvement in query performance. Using MDC can also significantly reduce the overhead of data maintenance operations, such as reorganization, and index maintenance during insert, update, and delete operations. Prefetching Enhancement: In DB2 V8 the performance of data prefetching can be improved by creating block-based buffer pools. This facility enables a single block I/O operation to read multiple pages from disk into contiguous pages of a DB2 buffer pool, which leads to better performance. Faster Page Cleaners: DB2 V8 exploits asynchronous I/O facilities to improve I/O performance. This can significantly improve the performance of DB2 page cleaning tasks, which flush modified buffer pool pages to disk. User-Maintained MQTs: Many warehouses have custom applications that maintain and load tables that are, in reality, pre-computed data that represents the result of a query. Designating a table as an MQT (formerly ASTs, automatic summary tables) can improve dynamic query performance without requiring users to modify the table. With DB2 V8, an MQT (an AST whose capabilities have been enhanced for V8) can remain available during a load append operation on the underlying table. After the load of the underlying table is complete, the MQT may be refreshed incrementally using only the appended data, which significantly reduces the refresh time. This improves the availability of MQTs to your users. Type-2 Indexes: DB2 V8 adds support for type-2 indexes. This provides improved concurrency, and the ability to invoke online reorganization and online load utilities. They are required for the new multidimensional clustering facility. Support for 64-bit Windows and 64-bit Linux: DB2 Universal Database will take the next leap in performance and scalability on 64-bit Windows and 64-bit Linux platforms by exploiting systems built around the 64-bit IPF processors from Intel. Systems built around Itanium and Itanium 2 processors will also be supported. In addition, DB2 V8 for Windows exploits the features of Intel Xeon MP processors by taking advantage of the new hyper-threading feature developed by Intel. Replication Enhancements: DB2 V8 Replication features improved usability, reliability, performance, serviceability, and security. The new DB2 Replication Center is a user interface tool that you can use to set up and administer your replication environment. It supports administration for DB2-to-DB2 replication environments, and administration for replication between DB2 and non-db2 relational databases. of the DB2 Control Center set of tools, the Replication Center includes all of the replication functionality previously available from the DB2 Control Center and the DB2 DataJoiner Replication Administration (DJRA) tool. Use the Replication Center to: Define defaults in profiles for creating control tables, source objects, and target objects Create replication control tables Register replication sources Create subscription sets and add subscription-set members to subscription sets

9 Operate the capture program Operate the apply program Monitor the replication process The Replication Center also includes a launchpad that allows you to perform the basic functions needed to set up a DB2 replication environment. The launchpad also shows you graphically how the different steps are related to one another. Basic replication performance has improved with JOINs eliminated in many situations, multithreaded capture, and faster full refreshes of target tables by exploiting DB2 LOAD improvements. Availability Enhancements Online Load Index Reorganization Utility: New in DB2 V8 is the ability to read and update a table and its existing indexes during an index reorganization using the REORG INDEXES command. Online Load Utility: With DB2 V8, you now have read access to the existing portion of a table during a load append operation. Online Reorganization Utility: DB2 V8 enhances database availability by allowing you to reorganize tables while permitting read and write online table access. Online Configuration Parameters: DB2 V8 improves availability characteristics with the capability to modify key database and database manager configuration parameters online so that they take immediate effect. This gives you more flexibility for deciding when to change the configuration to better suit current workload characteristics. In some cases you can set a parameter to be automatic, which allows DB2 to adjust the parameter s value without user intervention as workload on the system changes. Online Buffer Pool Operations: Efficient memory management is one of the key aspects of performance tuning. In DB2 V8, you can change how DB2 uses memory without stopping database activity. You can also add, drop, and change the size of a buffer pool without stopping database activity. Enhanced Table Space Container Operations: Table spaces that use Database-Managed Storage mechanism (DMS table spaces) support new operations that allow you to drop a container from a table space, reduce the size of existing containers, and add new containers to a table space without rebalancing. These operations allow greater flexibility in managing physical storage, such as ability to reclaim over-allocated space. All of these operations can be accomplished online with full access to the table space. INSERT through UNION ALL Views: The SQL INSERT statement is now supported for views that use a UNION ALL construction. This augments the UPDATE and DELETE capabilities provided in previous releases. Definition of a UNION ALL view over separate tables can be useful in an HSM environment where the view may range over a number of tables with some tables being stored by HSM on tertiary storage while other tables are stored on disk. The UNION ALL technique can also be used to deliver improved database scalability by allowing complete SQL functionality through a view, while at the same time maintaining database manageability through granular maintenance of individual tables. Application Development SQL is the language of DB2. With every release, DB2 enhances the SQL language to ensure that application programmers have rich language to improve their productivity and improve performance while adhering to the industry standards for SQL. V8 is no exception. SQL enhancements in DB2 V8 are standards-based and provide function that simplifies application development. V8 further enhances the power of the DB2 SQL language by introducing new SQL statements such as MERGE, and enhancing existing SQL by providing support for INSERT through UNION ALL, adding support for INSTEAD OF TRIGGER, ORDER BY and FETCH FIRST in subqueries, and supporting SQL queries in user defined functions. There are also significant enhancements to the CALL statement as well as addition of numerous new functions. Scrollable Cursors also benefit from several important enhancements. All of the key application drivers, ODBC, DB2 CLI, JDBC, SQLJ, and Embedded SQL, have been rearchitected for much higher performance and greatly reduced resource utilization. The new driver architecture provides excellent support for application servers with heavy work loads. In addition, key new features have been implemented in each of the drivers and a new Type 4 driver is now available. DB2 V8 delivers industry-leading support for XML, the standard data interchange for the next generation of business-to-business solutions. XML document storage and retrieval forms an integral part of DB2 and is provided as a combination of SQL language (library of XML functions) and DB2 XML Extender enhancements. Web Services is a key emerging technology for integrating applications and building applications from components. DB2 V8 delivers industry leading Web Services support by providing DBAs with ability to present stored procedures and SQL statements as Web Services and for application developers with ability to use these Web Services without having intimate knowledge of the details of their implementation. DB2 V8 can also act as a consumer of Web Services, presenting data provided by a Web service as if it was stored in DB2. More application developers build applications with component-based architectures, including applications that are based on Java 2 Platform Enterprise Edition (J2EE) and Java beans as components, Microsoft COM, and the new.net architecture. Web Services is an emerging technology that takes component-based application development to a new level. DB2 V8 improves on existing support for both Java and Microsoft component architectures, and also delivers industry-leading support for Web Services. XML has become the lingua franca of data interchange between applications and systems. DB2 V8 also delivers leading support for working with XML through improvements in SQL and the XML Extender. Development Center is a replacement for the Stored Procedure Builder. It offers application developers facilities to build, debug, test, and deploy Java and SQL stored procedures, SQL functions, and table functions that read MQSeries messages, access OLE DB data sources and extract data from XML documents

10 Development Center: Database server-side business logic (stored procedures, user-defined functions and structured data types) is an important part of many well-designed applications. DB2 Development Center provides an easy-to-use development environment that greatly simplifies the entire process of building stored procedures, user-defined functions (UDFs), and structured data types. It helps with developing, debugging, testing, and deployment of these application objects for DB2 servers. z/os. While it provides support for developing and debugging server-side logic in Java and Procedural SQL, stored procedures written in any language (for example, COBOL) can be tested within the Development Center. DB2 Development Center also provides an integrated debugger for debugging stored procedures and usability enhancements that allow programmers to browse contents of remote databases, as well as numerous project management features. To improve programmer productivity in Microsoft environments, the Development Center also provides a DB2 Add-In for Microsoft, Visual C++, Visual Basic, and Visual InterDev. With the add-ins, you can easily develop DB2 server-side logic without leaving your Microsoft development environment. WebSphere Studio plug-ins and Microsoft VisualStudio add-ins allow programmers using these integrated development environments (IDE) to build complete applications, including DB2 server business logic (stored procedures and user defined functions) without leaving the comfort of their favorite IDE. These plug-ins extend WebSphere Studio functionality to include development of DB2 server-side application logic. Applications that generate large amounts of data that need to be loaded into a table can now use a Call Level Interface (CLI) API that invokes the DB2 LOAD utility instead of using an array insert method. Using this option provides significant performance benefit for loading large amounts of data without the need to create an intermediate flat file. WebSphere Studio Site Developer V5 and WebSphere Application Server Advanced for Developers V4: These complementary products provide DB2 application developers with tools for building, debugging, and testing DB2 stored procedures and user-defined functions. WebSphere Studio Site Developer also provides full feature XML-to-relational schema mapping environment to utilize the native XML capabilities of DB2 UDB. Dynamic Web applications can be created using the latest Web Services framework that encapsulate DB2 server logic such as SQL statements, and stored procedures as Web Service providers. WebSphere Application Server Advanced for Developers provides a Java 2 Platform, Enterprise Edition 1.3 (J2EE) compliant server that can be used for development and testing of applications based on J2EE architecture. The use of these complementary products is restricted by a DB2-specific set of terms and conditions. Consult license information for additional information. SQL Assist Enhancements: With SQL Assist and some knowledge of SQL, you can create SELECT, INSERT, UPDATE, and DELETE statements. SQL Assist is a tool that uses an outline and details panels to help you organize the information that you need to create an SQL statement. DB2 V8 enhancements include: A redesigned user interface for easy inspection and modification of SQL statement elements Assistance for creating table joins SQL syntax checking The option to copy and paste an existing SQL statement into SQL Assist, then use the SQL Assist interface to make modifications Note: SQL Assist V7.2 remains in the Data Warehouse Center. SQL Enhancements Instead of Triggers: This type of trigger can simplify application programming. It allows developers to code inserts, updates, and deletes against views, while the actual update operation is re-directed to the appropriate underlying table. Insert through UNION ALL Views: The SQL INSERT statement is now supported for views that use a UNION ALL construction, augmenting the UPDATE and DELETE capabilities provided in previous releases. New Built-in Functions: The following trigonometric functions have been added to the SYSIBM schema: ATANH COSH SINH TANH ACOS ASIN ATAN ATAN2 COS COT SIN TAN ATANH, COSH, SINH, and TANH are new. The other functions were available under the SYSFUN schema; having them in SYSIBM offers a performance advantage. TRUNCATE, CEILING, and FLOOR have also been added to the SYSIBM schema. These built-in functions now support decimal values. Informational Constraints: DB2 V8 introduces a new type of constraint called informational constraints. The DB2 query optimizer can be enabled to perform query optimization on application-enforced constraints that DB2 knows about but does not enforce. Use of such informational constraints can eliminate the overhead of DB2 performing constraint checking, while still providing the benefit of optimized query performance. Not enforcing constraints by the database manager reduces the workload on DB2 while still retaining the performance advantage of performing query optimization in order to improve performance. User-Defined Functions and Methods: External user-defined functions and methods can now contain read-only SQL statements. Both static and dynamic SQL can be used. Other routines can be called from a function or method. Such nesting can include recursive calls of the routine and may invoke routines written in different languages. Some attributes of functions and methods can now be changed using the ALTER statement, rather than by dropping and recreating the routine
