This chapter describes how to work with Oracle Performance Manager chart windows in order to display Oracle Performance Manager charts. Specifically, it covers the following topics:

Chart Window Components
Defining a New Chart Window
Modifying an Existing Chart Window

You can think of a chart window as a frame containing one or more charts. Oracle Performance Manager charts are always displayed within chart windows.

Attention:

If a blank chart is displayed, either the chart window containing the chart is not high or wide enough to display it, or the chart window contains too many charts for its size. Either resize the window or remove charts from it.

Chart Window Components

A chart window includes the following components:

Title bar

Displays the chart window title and the name of the database to which a connection has been made. By default, the title of a chart window containing a single chart is the same as the title of that chart.

Menu bar

Includes the Window, Refresh and Help menus. The Help menu also appears in the Oracle Performance Manager main window, and is described in Oracle Performance Manager Overview on page 2-1. The Window and Refresh menus are described in the following sections,

Toolbar

Includes the Interval min and sec combo boxes which you can click on to change the automatic refresh interval for the chart(s) in this chart window. (The default is 30 seconds.)

Display area

Displays one or more charts. The chart title is displayed on the chart itself. If a drilldown chart window is available for a chart, this chart title is displayed with "..." appended to it.

Status bar

Describes the operation currently in progress.

Window Menu

The Window menu items allow you to print and close the displayed chart window.

The Window menu includes the following menu items:

Print

Prints the displayed chart window.

Close

Closes the chart window.

Refresh Menu

The Refresh menu items allow you to refresh the statistics displayed in the chart(s) of a chart window.

The Refresh menu includes the following menu items:

Automatic

Allows you to toggle between automatic and manual refresh mode. When a chart window is displayed, manual refresh mode is set by default.

When you toggle to automatic refresh mode, the statistics displayed in a chart window are automatically updated at the time interval shown in the Interval min and sec combo boxes in the chart window tool bar. The default automatic data refresh interval is 30 seconds.

A check mark next to the Automatic menu item indicates that automatic refresh mode is enabled. The absence of this check mark indicates that manual refresh mode is enabled.

Update Now

Executes the query and updates the statistics displayed in the chart window. This menu item is enabled only when manual refresh mode is enabled.

Defining a New Chart Window

To define a new chart window, select New Window from the Charts menu. The resulting New Window property sheet contains the following:

Window Name

Enter a unique name for the chart window you are defining.

Selected Charts

Displays the charts to be associated with this new Window Name. To add a chart to the Selected Charts box, select a chart in the Available Charts combo box and click on the Add button. To remove a chart from the Selected Charts box, select a chart name in this box and click on the Remove button.

Add

Click on this button to add a selected chart in the Available Charts combo box to the list of charts in the Selected Charts box.

Remove

Click on this button to remove a selected chart in the Selected Charts box from the list of charts associated with the Window Name. The chart will no longer be associated with the Window Name.

Available Charts

Lists predefined charts and user-defined charts that you can add to the list of charts associated with this Window Name. Click on a chart name and click the Add button to add a chart to the Selected Charts box.

OK

Click on the OK button to exit the property sheet and display the chart window you have defined.

Cancel

Click on the Cancel button to exit the property sheet without performing a task.

Apply

Click on the Apply button to display the chart window you are defining without exiting the New window property sheet.

Interval

Click on the min and sec combo boxes in the Interval group to change the automatic refresh interval for the chart(s) displayed in this chart window. The default automatic refresh interval is 30 seconds.

Layout of charts in window

Enter the number of charts to be displayed in a row in the chart window. (The default is 1.) For example, if two charts are to be displayed in the chart window and the value in this box is 1, the charts would be displayed vertically; but if the value were 2, the charts would be displayed horizontally.

Modifying an Existing Chart Window

To modify an existing chart window, select Modify Window from the Charts menu.

The resulting Modify Window property sheet is virtually identical to the New Window property sheet described in the previous section, "Defining a New Chart Window," but for the following exception:

Window Name

On the Modify Window property sheet, Window Name is a combo box you can use to select the user-defined chart window whose basic definition you want to modify.

When you select a Window Name from this combo box, the chart(s) associated with this chart window are automatically displayed in the Selected Charts box.
