3. 3 @ Copyright 2012 - IBM What is Data Studio 3.1.1? DB2 development software  Free Data Tooling software  Integrates into RDz  Becomes a Perspective + Views in the RDz workbench)  Provides:  Data Analysis Tools  SQL Programming Options  SQL Performance Analysis & Tuning Features  DB2 Table Editing Options  DBA Functionality

4. 4 @ Copyright 2012 - IBM Data Analysis Tools  Data Source Explorer – like RDz, but shows additional "physical" DB2 objects  Administrative Explorer – provides filtered lists of DB2 object meta-data. List includes Row Count, Tablespace/Database/Partitioning information, etc.  Context Menu – Overview diagram, access to list of user Privileges, host of DBA tools

5. 5 @ Copyright 2012 - IBM Additional Meta-Data  Discover the Database, Table Space and Storage Group for a Table  If authorized you can update Statistics for the Tablespace  Launches a series of DSNU… utilities  The table properties will reflect statistics

6. 6 @ Copyright 2012 - IBM Additional Meta-Data – Value Distribution in Table Columns  Same as selecting a column, and asking for: Data > Sample Contents (but a lot nicer visual representation)

7. 7 @ Copyright 2012 - IBM SQL Development Tools  Content Assist and Context menu options (like RDz Data tooling)  SPUFI-like run options  Additional SQL functionality for:  Visual Explain  OPTIM SQL Query tuning (requires InfoSphere z/OS components)  SQL Results view – same as RDz Data Perspective tooling  Can contract the tabs for more SQL coding real estate

8. 8 @ Copyright 2012 - IBM Context Menu  And SQL Results  Note – additional options available in Data Studio from the Context Menu

9. 9 @ Copyright 2012 - IBM Visual Explain  Multiple ways to invoke  Requires DB2 "Plan Tables"  Produces:  Illustration of Optimizer access path  Cost estimate of running query  Print/save graph, or Cost estimate

10. 10 @ Copyright 2012 - IBM Visual Explain of Complex SQL Statement  Requires deep (DBA-level) understanding of DB2 access path theory and (current) physical database design

11. 11 @ Copyright 2012 - IBM SQL Performance Tuning (SQL Query Advisor)  Requires IBM InfoSphere – installed on z/OS  Multiple steps/stages 1. Code the query  Run 2. Select tuning options 3. Select the tuning (Access Path) ` reports

12. 12 @ Copyright 2012 - IBM SQL Performance Tuning – Review the Query Advisor Recommendations 4. Review the various tuning and DB2 utility recommendations

13. 13 @ Copyright 2012 - IBM SQL Performance Tuning – Review the Access Plan Graph 6. Visual Explain – but with some additional analysis options (separate Query Block diagrams, etc.)

14. 14 @ Copyright 2012 - IBM SQL Performance Tuning – Explore each access plan Query Block 7. Each QB revealed, including: CPU Millisecond, I/O (VSAM & Paging) and Service Unit costs Note – Can save and compare versions of the same SQL for cost analysis

15. 15 @ Copyright 2012 - IBM SQL Performance Tuning – Review the Query Tuner Report Details 8. Recommended actions for utilities and Query re-coding

16. 16 @ Copyright 2012 - IBM SQL Performance Tuning – Capture the SQL Query – for Re-testing 8. Can select copy and paste the automatically tuned query – for iterative (subsequent) analysis runs

17. 17 @ Copyright 2012 - IBM SQL Performance Tuning – Capture the SQL Query – for Re-testing 9 There are a number of DBA-level reports available for study (scroll down for reports)

18. 18 @ Copyright 2012 - IBM Table Editing – Options From the Data Source Explorer:  Can edit multiple tables – but no table subsetting  Can also access (run utilities & reports against): Databases/Storage Groups/Tablespaces

19. 19 @ Copyright 2012 - IBM Table Editing – Subsetting and other options From the Administration Explorer  Right-click an object type  Use the Database Catalog Filter to expose specific objects for editing (and other) actions

20. 20 @ Copyright 2012 - IBM Table Editing - Options Some options same as RDz Data Tools – but others extend the functionality:  Browse rows (in tabular format)  Generate pureQuery Code  Manage DB2 privileges (GRANT/REVOKE)  Alter table  Generates DDL – even for options that require dropping a table  Runs script – or can run as Job

21. 21 @ Copyright 2012 - IBM Table Editing – Subsetting Start by editing the table data Select: Filter the data

22. 22 @ Copyright 2012 - IBM Table Editing – Subsetting  Select columns to show  Specify Row Selection conditions  Update Rows to Return Click OK

23. 23 @ Copyright 2012 - IBM DBA Functionality Execute RUNSTATS against the Tablespace Alter a table  Add a column  Add a Primary or Foreign key  Modify table GRANT (access permissions)

24. 24 @ Copyright 2012 - IBM What can you "not" do with OPTIM  Can't edit in hex  Can't copy/paste rows  Doesn't allow multiple table-subsetting "Templates"  All of the above can be done through the IBM PD Tools "File Manager" product
