2
Domain 2: Database Objects and Storage
3 topics
Tablespaces and Storage Groups
- Create tablespaces using CREATE TABLESPACE statement specifying SEGSIZE, LOCKSIZE, and BUFFERPOOL parameters
- Identify different tablespace types including simple, partitioned, partition-by-growth, and universal tablespaces
- Configure storage group definitions using CREATE STOGROUP with VOLUMES and VCAT specifications
- Analyze tablespace design decisions based on data access patterns, volume requirements, and partitioning strategies
Tables and Data Types
- Create tables using CREATE TABLE statement with appropriate Db2 z/OS data types including CHAR, VARCHAR, INTEGER, DECIMAL, DATE, TIME, TIMESTAMP
- Define primary keys, foreign keys, and check constraints using ALTER TABLE and CREATE TABLE statements
- Implement table partitioning strategies for large tables using PARTITION BY RANGE and PARTITION BY GROWTH
- Evaluate table design for optimal storage utilization considering row compression, variable length columns, and null values
Indexes and Views
- Create indexes using CREATE INDEX statement with clustering, partitioning, and uniqueness specifications
- Identify index types including clustering indexes, secondary indexes, and partitioned indexes in Db2 z/OS
- Create views using CREATE VIEW statement with column selection, joins, and WHERE clause filtering
- Analyze index design strategies for query performance optimization considering selectivity, clustering, and maintenance overhead
3
Domain 3: SQL Fundamentals and Operations
3 topics
Basic SQL Statements
- Execute SELECT statements with WHERE clause, ORDER BY, and aggregate functions like COUNT, SUM, AVG, MAX, MIN
- Perform INSERT operations using VALUES clause and INSERT with SELECT subqueries
- Execute UPDATE statements with WHERE conditions and correlated subqueries for data modification
- Implement DELETE operations with WHERE clause and referential integrity considerations
Advanced SQL Operations
- Construct inner joins, outer joins (LEFT, RIGHT, FULL), and cross joins between multiple tables
- Write correlated and non-correlated subqueries using EXISTS, IN, and comparison operators
- Implement GROUP BY and HAVING clauses for data aggregation and filtering grouped results
- Analyze complex SQL execution plans to identify performance bottlenecks and optimization opportunities
Data Manipulation and Transactions
- Execute COMMIT and ROLLBACK statements to control transaction boundaries and data consistency
- Implement MERGE statement for conditional INSERT, UPDATE, and DELETE operations in single statement
- Handle NULL values using IS NULL, IS NOT NULL, COALESCE, and NULLIF functions in SQL statements
- Evaluate transaction isolation levels and their impact on data consistency and concurrency in Db2 z/OS
4
Domain 4: Db2 Utilities and Maintenance
3 topics
Data Loading and Unloading
- Execute LOAD utility with control cards specifying input dataset, target table, and field specifications
- Configure LOAD utility parameters including REPLACE, RESUME, and error handling options
- Execute UNLOAD utility to extract data from Db2 tables to sequential datasets with specified format
- Troubleshoot LOAD utility errors using SYSPRINT, SYSERR, and SYSDISC datasets for data validation issues
Database Reorganization and Statistics
- Execute REORG utility for tablespaces and indexes to reclaim space and improve clustering
- Configure REORG utility options including SHRLEVEL, LOG, and mapping table specifications
- Execute RUNSTATS utility to collect and update catalog statistics for tables and indexes
- Analyze REORG and RUNSTATS output to determine optimal execution frequency and resource requirements
Backup and Recovery Utilities
