Creating Custom Grid Report for database availability

Oracle Enterprise Manager GRID Server contains built in reports to support Database

Administrators to generate sightly reports. However, in my company, we need some reports

that cannot be find in GRID and needs custom development. Here is how i did it.

First Thing is to click to "Reports" tab on the top, right hand side of the GRID Management

Console (figure_grid_management_console). This page is where all the predefined and custom

reports can be find. Now click on the "Create" Button on top of the page to create a new

custom report. "Create Report Definition" page comes to the screen. There are four tabs for

the definition of the report.

figure_grid_management_console

General

After specifiying title of the report then select category and subcategory from thecomboboxes. Category and subcategory defines our newly custom report's group and standing

place in the reports list of the GRID reports page. You can also create new categories by

clicking the buttons between the comboboxes.

Targets section enables you to limit the available list of target selection while generating the

report or you can select a specified target to be used. I used "Specified Target" and left the


2/8

textbox blank because this report will apply to all database and rac targets and is not allowed

to be changed.

You can enable to select time periods by end user or you can preset the time period from the

"Time Period" section (figure_create_report_general_tab). This custom report always displays

the last known and most updated state of the databases uptimes and downtimes.

Elements

In the Elements tab, you can define the report elements and their positions in the report page

(figure_add_elements_1). Report elements are structures that displays selected data from the

GRID Servers repository. Click "Add" Button to add elements. I used

IPMSG_USER_CHART_FROM_SQL and IPMSG_USER_TABLE_FROM_SQL elements

(figure_add_elements_2). Click on the "Set Parameters" icon on the right hand side of the listed

items to obtain a statement for the elements (figure_add_elements_2). Here you can enter the

sql statement that brings data into the element from Management Servers repository. Following

you can find the sql statements for the elements.
