What is Data Studio 3.1.1?

DB2 development softwareDB2 development software Free Data Tooling softwareFree Data Tooling software Integrates into RDz Integrates into RDz Becomes a Perspective + Views in the RDz workbench)

Provides:Provides:Data Analysis ToolsSQL Programming OptionsSQL Performance Analysis & Tuning FeaturesDB2 Table Editing OptionsDBA Functionality


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


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


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)


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


Context Menu

And SQL Results

Note – additional options available in Data Studio from the Context Menu


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


Visual Explain of Complex SQL Statement

Requires deep (DBA-level) understanding of DB2 access path theory and (current) physical database design


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


SQL Performance Tuning – Review the Query Advisor Recommendations

4. Review the various tuning and DB2 utility recommendations


SQL Performance Tuning – Review the Access Plan Graph

6. Visual Explain – but with some additional analysis options (separate Query Block diagrams, etc.)


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


SQL Performance Tuning – Review the Query Tuner Report Details

8. Recommended actions for utilities and Query re-coding


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


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)


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


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


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


Table Editing – Subsetting

Start by editing the table data

Select: Filter the data


Table Editing – Subsetting

Select columns to show Specify Row Selection conditions Update Rows to Return

Click OK


DBA Functionality

Execute RUNSTATS against the Tablespace

Alter a table Add a column Add a Primary or

Foreign key Modify table GRANT

(access permissions)


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"
