    The test contains five sections totalling approximately 69 multiple-choice questions. Thepercentages after each section title reflect the approximate distribution of the total question setacross the sections.Section 1 - Database Design and Implementation (30.5%)

    a. Design tables and views (columns, data type considerations for large objects, XML, column

    sequences,user-defined data types, temp tables, clone tables, MQTs, automatic creation ofobjects, etc.)

    b. Explain the different performance implications of identity column, row ID, and sequencecolumn definitions(applications, utilities), reorder row format

    c. Design indexes (key structures, type of index, index page structure, index column order,index space,clustering, compression, index on expression)

    d. Design table spaces (choose a DB2 page size, clustering) and determine space attributes(automatic space)

    e. Perform partitioning (table partitioning, index partitioning, DPSI, universal table space)f. Normalize data (E-R model, process model) and translate data model into physical model

    (denormalize tables)g. Implement user-defined integrity rules (referential integrity, user-defined functions, check

    constraints, triggers)h. Use the appropriate method to alter DB2 objects (table, index, table space, database)i. Create and Manage XML objects

    j. Understand impacts of different encoding schemes.

    Section 2 - Operation and Recovery (29%)

    a. Issue database-oriented commands for normal operational conditions (START, STOP,DISPLAY)

    b. Issue database-oriented commands and utility control statements for use in abnormalconditions (RECOVER, RESTART)

    c. Identify and perform actions that are needed to protect databases from planned andunplanned outages and ensure that timely image copies are taken periodically.

    d. Load and unload data into and from the created tablese. Reorganize objects when necessaryf. Monitor the object by collecting statistics (run stats, real time stats and DSNACCOR)g. Monitor and manage threads (distributed, local)h. Monitor utilitiesi. Identify and respond to advisory/restrictive statuses on objects

    j. Establish timely checkpoints (checkpoint frequencies, system quiesce points)k. Identify and perform problem determination (e.g., traces and other utilities)l. Perform health checks (maintenance, check utilities, offline utilities, queries)m. Develop backup scenarios (tables spaces; indexes; full pack; hardware; Flash copies; full,

    incremental, reference update; copy-to-copy, non-data objects; catalog) and recoveryscenarios (table spaces, indexes, roll forward, roll back, current point in time, prior point intime, system point in time copy and restore, catalog and directory)

    n. Describe the special considerations for recovery in a data sharing environmento. Implement disaster recovery

    1. Identify options in disaster recovery2. Plan for disaster recovery3. Perform disaster recovery (offsite, local)

    p. Design and alter index structures (data-partitioned secondary indexes [DPSI], VARCHARcolumn index implications, backward index scan, sparse indexes, index on expression)

    q. Monitor and manage virtual storage

    Section 3 - Security and Auditing (7%)

    a. Protect DB2 objects1. Establish security profile (define authorization roles)2. Identify the appropriate DB2 privileges required for access to DB2 resources3. Define and implement authorization and privileges on user and system database

    objects (revokes, grants)

    b. Protect connection to DB2 (SSL)

    c. Identify conditions when external security mechanisms (such as RACF) should be used inplace of DB2 internal security mechanisms

    d. Audit DB2 activity and resources and identify primary audit techniquese. Identify and respond appropriately to symptoms from trace output or error messages that

    signify security problemsf. Create and maintain roles and trusted contexts

    Section 4 - Performance (29%)

    a. Plan for performance monitoring by setting up and running monitoring procedures(continuous, detailed, periodic, exception)

    b. Analyze performance (manage and tune CPU requirements, memory, I/O, locks, responsetime, index and table compression)

    c. Analyze and respond to RUNSTATS statistics analysis (real-time, batch, catalog queries,reports, histograms)

    d. Determine when and how to perform REBINDe. Analyze and tune cache structures

    1. buffer pool tuning (sizes, threshold, object separation)2. RID pool, sort pool, and EDM pool

    f. Calculate cache requirements for new applications (DBD sizes, plan and package, average

    and maximum sizes, number of data sets)g. Evaluate and set appropriately the performance parameters for different utilitiesh. Describe the performance concerns for the distributed environment (DDF, DBAT threads,

    pool threads, connection pooling)i. Describe DB2 interaction with WLM (distributed, stored procedures, user-defined functions,

    RRS) j. Interpret traces (statistics, accounting, performance) and explain the performance impact of

    different DB2 traces

    3/3

    k. Identify and respond to critical performance metrics (excessive I/O wait times, lock-latchwaits and CPU waits; deadlocks, timeouts, RID failures)

    l. Review and tune SQL1. Interpret EXPLAIN output (HINTs & Visual Explain, index advisor)2. Analyze access paths (query parallelism; indexable, stage 1, and stage 2 predicate

    types; join methods; block fetching

    3. Dynamic SQL considerations (caching, parameter markers, reopt, identification, DSNstatement cache tables, OSC)

    4. Explain the performance impact of multi-row functionality (multi-row insert scenario,multi-row fetch, reordered row format)

    Section 5 - Installation and Migration / Upgrade (4.5%)

    a. Run catalog health checks using queries and utilitiesb. Identify the critical ZPARMs (database-, object- and application-oriented)c. Identify the migration/upgrade modes (feature availability, mode descriptions, migration

    paths)

    d. Identify & explain Datasharing components
