Solving the DB2 LUW Administration DilemmaRandy Goering
As a DB2 LUW Database Administrator you are probably reluctant to or prohibited from granting your users* these permissions because doing so gives them permission to other DB2 administrations tasks like stopping the database. If your users are not allowed to do these tasks then who is? Most likely, you, as the DBA will perform these and other administrative functions for your users. Would you like a way to eliminate these tasks from your daily to-do list? This presentation will discuss how to externalize specific administrative tasks with Stored Procedures, Federated procedures, Administrative SQL routines, and views.

DB2 is a family of database server products developed by IBM that support relational and object relational models. DB2 was first introduced by IBM in 1983 for mainframe systems and has since been ported to Linux, Unix, and Windows. There are three main DB2 products: DB2 for Linux, Unix, and Windows (DB2 LUW), DB2 for Z/OS (mainframe), and DB2 for iSeries. DB2 LUW provides features such as high availability, security, workload management, and federation between data sources. The document discusses DB2 architecture including the instance model, database storage model, engine dispatchable units, and memory architecture.
Flashback technology allows users to view and recover data to previous points in time. The document discusses several Flashback features: Flashback Query lets users view data as of a past time; Flashback Version Query shows row versions between times; Flashback Table recovers an entire table; and Flashback Transaction backs out changes from a problematic transaction. The document provides examples and considerations for using each Flashback feature.
This document discusses how Oracle databases automatically manage space and techniques for optimizing space usage. It covers deferred segment creation, compression, monitoring tablespace usage, using the segment advisor to identify space savings opportunities, and shrinking segments to reclaim space. Resumable space allocation is also described to allow DML statements to resume if suspended due to space issues.
The document discusses the top 12 new features of Oracle 12c, including improved column defaults that allow identity columns, increased size limits for VARCHAR columns up to 32K, improved queries for top-N results using ROW LIMIT clauses, and adaptive execution plans that allow the optimizer to choose alternative execution plans based on statistics gathered during the first execution. Temporary undo segments are also introduced to avoid generating redo for temporary table operations.
The document discusses DB2 architecture and concepts. It explains that each DB2 installation has a Database Administration Server (DAS) that provides remote administration support. It also discusses the DB2 Profile Registry, which stores configurable settings. The document then covers the instance concept, noting that an instance is a set of processes, disk, and memory allocations that provide database services and can contain one or more databases.
The document describes various DB2 online utilities including UNLOAD, LOAD, REBUILD INDEX, COPY, RECOVER, RUNSTATS, MODIFY RECOVERY, QUIESCE, and REORG. These utilities perform functions like unloading and loading data, rebuilding indexes, taking image copies of data, recovering data to a prior point in time, updating catalog statistics, and reorganizing tablespaces.
Flashback Database allows rewinding a database to undo data corruptions or errors. It works by using redo logs and block images to restore the database to a previous state. Configuring Flashback Database requires enabling it, setting a retention target, and having the database in ARCHIVELOG mode. Operations include flashing back to a time, SCN, or restore point. Monitoring involves checking the flashback window and log sizes.
This document discusses how to configure Oracle database backup settings using Recovery Manager (RMAN). It covers setting persistent RMAN configuration settings, enabling automatic control file backups, configuring backup destinations and channels, optimizing backups, and creating compressed or encrypted backups. Key topics include using the CONFIGURE command to set backup retention policies, backup copy settings, and backup optimization parameters, as well as allocating channels and specifying backup device types and locations.
Optimal query access plans are essential for good data server performance and it is the DB2 for Linux, UNIX and Windows query optimizer's job to choose the best access plan. However, occasionally queries that were performing well suddenly degrade, due to an unexpected access plan change. This presentation will cover a number of best practices to ensure that access plans don't unexpectedly change for the worse. All access plans can be made more stable with accurate DB statistics and proper DB configuration. DB2 9.7 provides a new feature to stabilize access plans for static SQL across binds and rebinds, which is particularly important for applications using SQL Procedural Language. When all else fails, optimization profiles can be used to force the desired access plan. This presentation will show you how to develop and implement a strategy to ensure your access plans are rock-solid.

It involves 7 stages: 1) preparing the source system, 2) putting the database in backup mode and copying files, 3) copying application files, 4) copying files to the target, 5) configuring the target database, 6) configuring the target application tier, and 7) finishing tasks like updating profiles. Key steps include applying required patches, running preclone scripts, copying database and application files, recovering the database using the backup control file, and configuring the cloned application and database tiers.
This document discusses Kumaran Systems' solution for migrating legacy COBOL/CICS applications to the J2EE platform. The solution involves a two-phase process: 1) converting VSAM data to a database like DB2, and 2) converting the COBOL/CICS application to J2EE. For the data conversion, the tool builds a VSAM file structure repository and then generates code to unload the data to flat files before loading it into the target database. For the application conversion, the tool migrates BMS maps, COBOL programs, and transactions to a multi-tier J2EE architecture using technologies like EJB, JPA and REST web services.
White Paper, System Z Dataset Naming StandardsDan O'Dea
The document discusses dataset naming standards for system-Z. It recommends a standard that uniquely identifies the owning application, whether the data is for production or test, and the type of data. This standard provides clarity, ease of security, automation, and storage management. The main disadvantage is that transitioning legacy systems to this standard requires changing dataset names wherever they occur.

A company’s success depends on critical application performance and availability. Upgrades and patches can improve application efficiency and user experience, but making the necessary changes requires resource intensive environments to test updates before deploying them. What’s more, these applications need to continue accessing data even in the event of an on-premises crisis.
Our Dell EMC VMAX 250F and PowerEdge server solution supported test/dev environments and production database applications simultaneously without affecting the production applications’ performance. Storage latency for the VMAX 250F peaked at a millisecond in our testing while IOPS stayed within an acceptable range. The solution also kept data highly available with no downtime or performance drop when we initiated a lost host connection for the primary storage. Consider the Dell EMC VMAX 250F array for your datacenter to support the critical database applications that drive your company.
