What's New in DB Optimizer 3.6/XE3.5

Connectivity/Data Source

• Custom Data Source Categories - In previous releases, when assigning a category to a data source, your choices were restricted to a set of default categories: Development, Production, Test, and QA. You can now create your own custom categories, providing a category name, short name, and identifying color for each.

Profiling

• Oracle Procedures Load Details - When profiling against an Oracle (10g or higher) data source, the Top Activity area and the Profiling Details pane now have deidcated Procedures tabs that provide information about the procedures load on the data source.
• Oracle Blockers Tab - A new profiling tab provides details on blocking sessions.

Tuning

• DB2 9.7 Execution Statistics - When tuning against a DB2 9.7 data source, the Overview tab, the Generated Cases area now includes additional sets of statistics gathered for the suggested cases. Available statistics now include Elapsed Time, Result, Rows Returned, Physical Reads, Logical Reads, CPU Time, Direct Reads, Sorts, Sort Time, and Sort Overflows.
• New SQL Server Analysis Tabs - When tuning against a SQL Server data source, additional statistics are available on the new Table Statistics and Column Statistics and Histograms tabs. A new Plan Guides tab is also available.
• Oracle Database Links - This release introduces improved support for tuning of statements referencing DBLINK objects.
• Oracle OPTIMIZER_FEATURES_ENABLE hint - Lets you enable Optimizer features for a specified Oracle release.
• Oracle 11g R1 and R2 hints - DB Optimizer tuning now supports the USE_INVISIBLE_INDEXES, NO_USE_INVISIBLE_INDEXES, INDEX_RS_ASC, INDEX_RS_DESC, IGNORE_ROW_ON_DUPKEY_INDEX, BIND_AWARE, NO_BIND_AWARE, NO_RESULT_CACHE, RESULT_CACHE, NO_STATEMENT_QUEUING, and STATEMENT_QUEUING hints.
• Oracle 10g R2 hints - DB Optimizer tuning now supports the USE_HASH_AGGREGATION, NO_USE_HASH_AGGREGATION, NATIVE_FULL_OUTER_JOIN, NO_NATIVE_FULL_OUTER_JOIN, NO_XML_DML_REWRITE, and PRECOMPUTE_SUBQUERY hints.
• New SQL Server Table Hints - Two new table hints are now available against SQL Server 2008 data sources. FORCESEEK forces the optimizer to use an index seek operation as the access path to the referenced table or view. FORCESCAN forces the optimizer to use an index scan operation as the access path to the referenced table or view.

Before installing the plug-in version of DB Optimizer, ensure that Eclipse and Java are installed on your machine. You can download Eclipse from the following Web site: www.eclipse.org/downloads.

DBMS Support

SQL Execution, Tuning and DBMS Support

SQL execution and SQL tuning with DB Optimizer is supported on the following DBMS platforms and versions:

• Oracle (9i - 11g)
• Sybase (12.5 - 15.x)
• IBM DB2 for LUW (8.0 - 9.x)
• MS SQL Server (2000, 2005, 2008 R2)
• JDBC (execution only)

SQL Profiling and DBMS Support

SQL profiling with DB Optimizer is supported on the following DBMS platforms and versions:

• Oracle (9i - 11g)
• Sybase (12.5.0.3 - 15.x)
• IBM DB2 for LUW (8.2 - 9.x)
• MS SQL Server (*2000 SP3, 2005, 2008 R2)

* On Microsoft SQL Server 2000, the Profiling feature is only supported if Service Pack 3 (SP3) is installed.

Note: DB Optimizer does not access in any way, shape or form any of the information, tables or views licensed under Oracle's diagnostic pack.

Release Notes

Upgrade Notes

• DB Optimizer should be installed in a different directory than previous versions of DB Optimizer. If DB Optimizer is installed in the same directory, the following error will result in at application start up: "Unable to read workbench state. Workbench UI layout will be reset.
• If a previous version is already installed on your machine, either change the default Workspace or delete all files from the Workspace directory. The Workspace directory location appears whenever you start Optimizer, and can be redefined from this dialog box. If the same Workspace is indicated for the new version as was indicated previously, the following error will result: "Cannot restore workbench layout".
• If DB/Optimizer is already running, you can also modify the Workspace directory by choosing File > Switch Workspace > Other from the Main Menu.

• We strongly suggest selecting a new workspace when upgrading from a previous version of DB Optimizer.
• Saved profiling and tuning session files (.oar) created using previous versions of DB Optimizer are not compatible with current versions. You can however have more than one version of DB Optimizer installed on the same system. To read old .oar files, run the older version of DB Optimizer.
