Blocking History

The Lock Analysis displays all locks that took place within the selected time range.

The lock analysis feature is integrated as part of the performance tree and it displays all the lock trees including further details for both the blocker and the blocked session including:

•

Lock event start date

•

Session Identifier – [Sid,SERIAL#]

•

Session Identifier of the blocker

•

Locked Object Name

•

•

•

•

•

•

Activity Highlights

The Activity Highlights are provided for fast performance analysis and allow users focus on the most significant dimensions that are relevant for the resource selected in the selected time range.

This pane comprises the following elements:

•

Summary — Summarizes the instance consumption time by % of the total instance activity.

•

Activity Highlights table — Displays the activity highlights, resource breakdown usage, and the top wait event that the instance is waiting on within the selected time range.

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:

•

Execution plan — SQL statements whose execution plans have changed. Unsuitable execution plans can result in SQL performance degradation.

•

Oracle configuration — instance-level configuration, such as init.ora parameters, location of files (data, log, and control), size and status

•

Oracle schema — any schema object, such as tables and indexes and their partitions, clusters, constraints, views, and materialized views.

•

System configuration — hardware and operating system configuration, such as OS global parameters, amount of RAM, and number of CPU units.

•

User-defined — used for documenting changes inserted manually by the user, which can affect performance. Recording this activity can assist in determining whether a change in performance can be directly associated with this event

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:

•

From a Change Tracking pane by clicking on a row that displays Execution Plan change.

•

From History by selecting the statement or batch and by clicking Analyze in the top of the table.

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

Plan analysis section

The execution plan is contains 3 tabs:

•

Plan details — Displays details of each operation in the execution plan.

•

Operation Analysis — Displays statistics aggregated per each operation in the execution plan.

•

Object Analysis - Displays statistics aggregated per each object in the execution plan. Each object is clickable and displays a popup with important performance-related information.

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.
