Viewing Change Tracking

The change tracking tool is an integrated monitoring mechanism. It periodically tracks changes in environments and activity that can potentially influence system performance and enables the user to view correlation between occurrences of changes and Oracle’s activity and behavior patterns.

Use the Categories filter mechanism to refine the set of displayed change tracking occurrences. These categories are displayed on the right hand side of the pane and include:

Viewing Execution Plans

This view presents the execution plan of a selected SQL and the cost of it. A Historical execution plan can be generated and will present any two views of the execution plan.

There are two ways to access the Execution Plan History dialog:

The execution plan dashboard displays the following content.

Resolving Date — Displays all the execution date and time of the selected statement.

Type — Displays the type of the execution plan.

Plan Hash Value — Displays the plan hash value of the execution plan

The execution plan contains 3 tabs:

By clicking the Generate Plan button the execution plan is generated and can be viewed. By clicking on the Compare Plan button a pop up will appear that allows comparing all available execution plans of the selected SQL statement.

Comparing Performance

Use the SQL PI Compare where differences in period activity illustrate underlying performance and monitoring issues. It helps you determine whether a comparison occurrence is an isolated incident or a sign of a potentially significant performance problem.

Compare can be accessed from the Performance tree.

The comparison can be of whole instances or selected dimension breakdowns (such as user or SQL). Use Compare to address questions such as:

The upper panes graphically displays the Workload or any other selected resource.

The middle Activity section displays the dimensions which were significant elements of the difference. Expanding the individual lines displays the dimension members which caused the difference and the composing metrics whose differences exceed the specified threshold.

Use the set of performance related metrics (defined by the chosen resource) to help you explain the difference in resource consumption; for example, a rise in I/O Wait might be explained by a rise in the quantity of physical reads.

Use the Comparison Parameters section in order to enter all the desired information for the cooperation. For example, time range, instance, dimension, time frames, resource.

Oracle Activity Drilldown

Use the Oracle Activity drilldown to carry out the operations described in the following topics:
