Skills taught

  • Execute program preparation steps including resolving common problems, defining collections and packages, and versioning of packages
  • Alter table characteristics such as data types of columns and identify the impact of making such changes
  • Alter indexes to add columns or to change the varying length or clustering characteristics of the index, and identify the impact of making such changes
  • React to the "Advisory Reorg" Database Exception Table state
  • Make appropriate decisions to successfully handle table space versions
  • Use parallel index build with the LOAD, REORG and REBUILD INDEX utilities
  • Load partitions in parallel
  • Determine the appropriate LOAD options to use while considering concurrency and performance requirements
  • Choose appropriate options with REORG and UNLOAD to achieve optimal performance and availability
  • Given the usage of the data, determine an appropriate option for dealing with the need for adding partitions or rebalancing data partitions
  • Provide appropriate LISTDEF, TEMPLATE, and OPTIONS utility control statements for use in DB2 utilities
  • Determine the applicability and implement user-defined distinct types, user-defined functions, stored procedures, triggers, and large objects

Course outline

Program preparation and use of packages

  • Go through the program preparation steps and execute programs in the DB2 environment using the TSO attachment facility
  • Resolve some of the most commonly occurring problems, for example SQL error -805
  • Understand the importance of collections and packages
  • Understand how to access different tables and views at execution time without changing the program
  • Handle mirror tables
  • Understand package versioning

Online schema changes

  • Change data types and lengths of columns
  • Alter or add an index to have true VARCHAR columns
  • Unbundle partitioning and clustering
  • Relate implications of renaming a column in a table or renaming an index

LOAD and REBUILD INDEX performance and availability

  • Build indexes in parallel during LOAD and REBUILD INDEX
  • Establish inline statistics during LOAD and REBUILD INDEX
  • Load partitions of a partitioned table space in parallel
  • Use the availability feature for LOAD RESUME YES: SHRLEVEL CHANGE
  • Use the availability feature for CHECK DATA: SHRLEVEL CHANGE
  • Use the availability feature for REBUILD INDEX: SHRLEVEL CHANGE
  • Use online LOAD REPLACE functionality provided by clone tables

REORG and UNLOAD performance and availability

  • Apply performance features for REORG
  • Build indexes in parallel during REORG
  • Use the availability features for REORG: Read-only online REORG: SHRLEVEL REFERENCE, and Full online REORG: SHRLEVEL CHANGE
  • Establish inline statistics during REORG
  • Use the performance and availability features for UNLOAD

Partition management

  • Add partitions
  • Rotate partitions
  • Rebalance partitions

Generic utility jobs

  • Provide reusable list definitions for use by DB2 utilities
  • Use list definitions in utility control statements and understand how they expand
  • Describe the concept and working of templates replacing utility DD statements
  • Use templates in utility jobs to simplify JCL
  • Use templates together with list definitions
  • Use the OPTIONS utility control statement to control execution parameters for utility jobs

UDTs, UDFs, and stored procedures

  • Identify the need for, define, and use schemas
  • Use schemas in the PATH bind option
  • Identify the need for, define, and use user-defined distinct types
  • Differentiate between external scalar functions, external table functions, SQL scalar functions, and sourced functions
  • Determine which user-defined function or stored procedure will be invoked given the invocation statement and existing functions or stored procedures
  • Identify privileges associated with schemas, user-defined distinct types, and stored procedures
  • Differentiate between the capabilities of user-defined functions and stored procedures
  • Create a user-defined function
  • Create a stored procedure
  • Explain SQL PL versioning and deployment

Triggers

  • Identify benefits of triggers
  • List characteristics of and functions that can be performed by BEFORE, AFTER and INSTEAD OF triggers
  • Specify trigger granularity
  • Create a trigger
  • Use transition variables and transition tables within triggers
  • Identify privileges associated with trigger definition
  • Describe the trigger package

Large objects

  • Identify the data types of large objects
  • Describe auxiliary table
  • Explain the relationship between the base table and the auxiliary table
  • Define large objects
  • Identify the use of ROWIDs with large objects
  • List alternative ways to process large objects within applications
