What's New in DB Optimizer 1.5

Interface Reorganization

DB Optimizer has been reorganized into three major interface pieces. This enhancement provides users with a more comprehensive workflow when analyzing queries across the enterprise, and provides more efficient task management in terms of time and efficiency, overall:

Continuous Monitoring of Data Sources

Profiling now enables the continuous monitoring of data sources by providing real time updates to the interface. This feature can be turned on and off via profiling configuration settings, and provides custom tweaking to suit machine efficiency with adjustable screen refresh rates in seconds.

Track Top Activities

The Track Top Activity Section enables users to examine more detailed information on waiting and executing sessions over the length of the session. When you select an item from the Top Activity Section, details about your selection appear in the Profiling Details view, automatically.

Statement, Event, and Session Drill Down Functionality

Using the Top Session and Profiling Details views, you can drill down into statements, events, and sessions that have been monitored by SQL profiling. This feature enables you to view and diagnose the underlying code in order to troubleshoot inefficient or otherwise not-ideal queries running on a data source.

Cross Platform Data Source Support

In addition to Oracle platforms, Tuning now supports Generic JDBC, IBM DB2 LUW, Microsoft SQL Server, and Sybase data sources. This enables more complete monitoring and tuning sessions that improve the efficiency of your entire enterprise. See the DBMS Support section of these release notes for a full and comprehensive list of supported DBMS platform types.

Installation Issues

DB Optimizer 1.5 should be installed in a different directory than DB Optimizer 1.0. If Optimizer is installed in the same directory, the following error will result at application start up: "Unable to read workbench state. Workbench UI layout will be reset".

Additionally, DB Optimizer 1.5 should be installed in a different directory than previous Beta versions. If the beta 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 in a prompt whenever you start Optimizer, and can be redefined from this dialog box. If the same Workspace is indicated for 1.5 as was indicated for the Beta, the following error will result: "Cannot restore workbench layout".

If Optimizer is already running, you can also modify the Workspace directory by choosing File > Switch Workspace > Other from the Main Menu.
