4 Adding Reports

Defining new target types in Enterprise Manager via Management Plug-ins also provides you with the opportunity to add new report definitions. Plug-ins allow you to add permanent (SYSTEM) target type-specific report definitions to Enterprise Manager using the Information Publisher PL/SQL API.

This chapter covers the following:

Note:

You must have a working knowledge of SQL and PL/SQL before using this API. Refer to the Oracle Database PL/SQL User's Guide and Reference for more information.

What You Get

Adding report definitions via Management Plug-in creates target type-specific SYSTEM reports. SYSTEM report definitions are handled differently than definitions created through the Information Publisher user interface. SYSTEM reports are permanent and cannot be deleted or edited by Enterprise Manager administrators. You can add multiple report definitions to a Management Plug-in, thus allowing you to associate multiple reports with a specific target type.

Adding SYSTEM report definitions using Management Plug-ins and the Information Publisher API allows users to access reports from two areas of the Enterprise Manager console:

Reports Page (Target Home Page)

In the report definition file, you can specify whether or not a report is available from the Reports page of the target home page. Report definitions you add to the Reports page are available from the View Reports drop-down menu list. The following figure shows the Reports page for a Microsoft SQL Server target.

Figure 4-1 Microsoft SQL Server Reports Page

Description of Figure 4-1 follows
Description of "Figure 4-1 Microsoft SQL Server Reports Page"

Report Definitions Page

Regardless of whether you specify that a report appear in the Reports page, all report definitions added via Management Plug-ins are available from Information Publisher's Report Definitions page. As with out-of-box SYSTEM report definitions, those added via Management Plug-ins are organized according to report category and subcategory. SYSTEM report definitions cannot be deleted from the Enterprise Manager console. Figure 4-2, "Report Definitions Page" shows available report definitions for Microsoft SQL Server target types.

Report Definition File

A report definition file is structured as a conventional PL/SQL block and contains code to extract pertinent information from the Management Repository and the report elements used to format and display that data. The Information Publisher PL/SQL API allows you specify the report elements and parameters that you normally specify interactively when creating a report definition from the Enterprise Manger console.

The following example shows the Reports page for an "oracle_orgchart" target type that was added as a Management Plug-in. A single report titled "Org breakdown by title (oracle_orgchart)" is shown in Figure 4-3. This report consists of three major areas: a pie chart showing the percentage distribution of people by title, a bar chart showing the top five managers having the most people reporting to them, and a table listing all managers in the organization the total number of direct reports.

Figure 4-3 Oracle Organization Report

Description of Figure 4-3 follows
Description of "Figure 4-3 Oracle Organization Report"

The report definition used for this example utilizes two report element types: Chart from SQL (pie and bar), and Table from SQL. In general, these two report elements will meet most reporting needs.

Creating a Report Definition File

Management Plug-ins allow you to define as many report definition files as is required for a particular target type. The content of a report definition file consists of a PL/SQL block that uses the Information Publisher PL/SQL API (part of the MGMT_IP package) to construct a report.

Report Definition File Development Process

The process of developing a valid report definition file involves three steps:

  1. Define SQL or PL/SQL queries used to extract information from the Management Repository.

  2. Create a test report interactively from the Enterprise Manager console.

  3. Use the PL/SQL API to create a report definition file.

Define SQL or PL/SQL queries used to extract information from the Management Repository.

The first step in creating your report definition is to create the SQL or PL/SQL queries used to extract the requisite report information from the Management Repository. Enterprise Manager provides management views with which you can safely extract data from the Management Repository without reading from the base tables. Using repository views protects your queries from changes to the repository schema that may occur in future releases and ensures your SYSTEM report definitions remain functional. A complete listing of repository views can be found in Chapter 6, "Management Repository Views".

The following query was used to extract repository information about the distribution of employee classifications within an Oracle organization. The query uses the MGMT$METRIC_CURRENT repository view.

select 'senior mts', count(value) from mgmt$metric_current 
where metric_column = 'Title' and LOWER(value) like '%senior member%' and 
      target_guid = ??EMIP_BIND_TARGET_GUID??  
union 
select 'principal mts', count(value) from mgmt$metric_current 
where metric_column = 'Title' and LOWER(value) like '%principal member%'and   
      target_guid = ??EMIP_BIND_TARGET_GUID??  
           union 
           select 'consulting mts', count(value) from mgmt$metric_current 
           where metric_column = 'Title' and LOWER(value) like '%consulting%' and 
                 target_guid = ??EMIP_BIND_TARGET_GUID?? ;

When an administrator views a report from the Enterprise Manager console that contains this SQL query string, Information Publisher automatically binds the unique identifier for the selected target to the ??EMIP_BIND_TARGET_GUID?? placeholder in the SQL query string. The documentation for Chart from SQL and Table from SQL parameters provide information on this bind variable placeholder as well as others you can include in your SQL query string.

The data returned from the SQL query is then used by the Chart from SQL report element to render the pie chart shown in the Reports page of an oracle_orgchart target home page as shown in Figure 4-3.

Create a test report interactively from the Enterprise Manager console.

Once you have written and tested the SQL or PL/SQL query, you can use the Enterprise Manager console to generate a version of your report interactively using the Chart from SQL and Table from SQL report elements. By using the Information Publisher user-interface, you can easily prototype reports without having to create a report definition file and import Management Plug-in Archives. You can also use this method of interactive prototyping to refine your queries and ensure that the data extracted from the Management Repository and how that information is rendered in your report meets your reporting requirements. See Enterprise Manager online help for the Chart from SQL and Table from SQL 'Set Parameters' function for information and examples on how to format your queries.

Use the PL/SQL API to create a report definition file.

Once you are satisfied with the way your report is being rendered by Information Publisher, you are ready to create the report definition file. As previously mentioned, the report definition file consists of a PL/SQL block defining the report elements and the SQL or PL/SQL queries used by the elements to extract repository information and render the report. Example 4-1 shows the content of the report definition file associated with the oracle_orgchart target type.

Report Lifecycle: Updating Report Definitions

With the ability to add report definitions to Enterprise Manager comes the responsibility of maintaining and updating the report definitions. Familiarity with the way in which Enterprise Manager handles report definitions will allow you to anticipate system behavior and plan for backwards compatibility.

When report definitions are deployed via Management Plug-in, Enterprise Manager only allows newer versions of the report definitions to be installed. Older report definitions are deleted and deregistered so as not to appear on the Reports subtab of a target home page. These actions eliminate potential version conflicts by ensuring that updated report definitions are deployed to clean systems. Enterprise Manager will not install older versions of a report definition.

Report definitions, as with Management Plug-ins in general, should be designed with backwards compatibility in mind. Future versions of report definitions should support previous versions of the target type metadata. Report definition-metadata version incompatibility will be most apparent in the following situations:

  • Report definitions included with Management Plug-in version 1 AND not included with Management Plug-in version 2 will disappear when version 2 is deployed, even if version 1 deployments remain on some Management Agents.

  • If version 1 and version 2 of a Management Plug-in are both deployed to the system, Management Agents will collect data based on the metadata of the version installed at that Agent; some will collect for version 1 metadata and some for version 2 metadata. Only the version 2 report definitions will be installed (appear in the Enterprise Manager console). For this reason, version 2 report definitions must support both versions of the metadata.

PL/SQL Application Programmer Interface

The Information Publisher PL/SQL API allows you to create a report definition file.

PL/SQL Methods for Creating Report Definitions

Use the following PL/SQL methods to create and/or manipulate report definitions when creating report definition files.

mgmt_ip.create_report_definition

Call this method to create a new report definition. Once a report definition is created, elements can be added. The create_report_definition method is part of the MGMT_IP PL/SQL package.

Note:

All of the Management Plug-in reports should set p_system_report to 1. This parameter defines the report definition as a SYSTEM report, which cannot be deleted or edited by Enterprise Manager administrators. p_owner should be set to mgmt_user.get_repository_owner for all Management Plug-in reports.

The p_component_name must be set to the target type of the management plug-in.

Input

Parameter Description

p_title_nlsid

report title.

p_description_nlsid

description

p_owner

owner name (should be the value returned from mgmt_user.get_repository_owner for Plug-In reports)

p_category_nlsid

category name

p_sub_category_nlsid

subcategory name

p_late_binding_target_types

target type for late binding, or null if not late binding

p_show_table_of_contents

PL/SQL Type Definitions

Three PL/SQL types are required to use the PL/SQL methods documented in Chapter4, "PL/SQL Methods for Creating Report Definitions" . The definitions for these types are shown below.

MGMT_IP_TARGET_TYPES

Use MGMT_IP_TARGET_TYPES type to pass the target type your report definition supports to the create_report_definition API as the p_late_binding_target_types parameter.

CREATE OR REPLACE TYPE MGMT_IP_TARGET_TYPES 
AS TABLE OF VARCHAR(64);

Example 4-2 MGMT_IP_TARGET_TYPES

DECLARE
 l_target_type   MGMT_IP_TARGET_TYPES; 
BEGIN
        -- specify the target type associated with this report
        -- in this case the target type is 'oracle_orgchart'
           l_target_type := MGMT_IP_TARGET_TYPES();
           l_target_type.extend(1);
           l_target_type(1) := 'oracle_orgchart';
END;

MGMT_IP_PARAM_VALUE_LIST and MGMT_IP_PARAM_VALUE_RECORD

Use the MGMT_IP_PARAM_VALUE_LIST type to pass parameter values to the create_report_definition API as the p_parameters parameter and to the add_element_to_report_def API as the p_paremeters parameter.

CREATE OR REPLACE TYPE MGMT_IP_PARAM_VALUE_LIST AS TABLE OF MGMT_IP_PARAM_VALUE_RECORD;

Use the MGMT_IP_PARAM_VALUE_RECORD type to create a named parameter value pair to add to an object of type MGMT_IP_PARAM_VALUE_LIST.

CREATE OR REPLACE TYPE MGMT_IP_PARAM_VALUE_RECORD 
AS OBJECT (PARAM VARCHAR2(100),  VALUE CLOB); 

Example 4-3 MGMT_IP_PARAM_VALUE_RECORD and MGMT_IP_PARAM_VALUE_LIST

DECLARE
           l_param_values  MGMT_IP_PARAM_VALUE_LIST;  
BEGIN
           l_param_values := MGMT_IP_PARAM_VALUE_LIST();
           l_param_values.extend(2);
           l_param_values(1) := MGMT_IP_PARAM_VALUE_RECORD(

To specify this using the PL/SQL API when creating your report definition file, set the following parameters for your report definition.

Example 4-5 Dynamic Time Selector Report Definition Parameters

l_param_values := MGMT_IP_PARAM_VALUE_LIST();
    l_param_values.extend(3);

    -- this report has a time period associated with it
    l_param_values(1) := MGMT_IP_PARAM_VALUE_RECORD(
      'oracle.sysman.eml.ip.render.elem.TimePeriodOption',
      'true');

    -- the user can customize the time period while viewing the report
    l_param_values(2) := MGMT_IP_PARAM_VALUE_RECORD(
      'oracle.sysman.eml.ip.render.elem.TimePeriodUserCust',
      'true');

    -- set the default value to last 24 hours
    l_param_values(3) := MGMT_IP_PARAM_VALUE_RECORD(
      'oracle.sysman.eml.ip.render.elem.TimePeriodParam',
      '0:0');

Pass l_param values to mgmt_ip.create_report_definition as the p_parameters argument.

If you are using Table from SQL or Chart from SQL report elements, you can structure your SQL statement such that the start and end dates will be bound automatically for you by Information Publisher. You achieve this by inserting placeholders (for example, ??EMIP_BIND_START_DATE??) for the start and end date values as shown in Example 4-6.

Example 4-6 Automatic Binding of Start and End Dates

'SELECT COLUMN_LABEL, ROLLUP_TIMESTAMP, AVERAGE
        FROM MGMT$METRIC_HOURLY
        WHERE TARGET_GUID = ??EMIP_BIND_TARGET_GUID??
        AND METRIC_LABEL = ''Load''
        AND KEY_VALUE = '' ''
        AND ROLLUP_TIMESTAMP > ??EMIP_BIND_START_DATE??
        AND ROLLUP_TIMESTAMP < ??EMIP_BIND_END_DATE??
        ORDER BY ROLLUP_TIMESTAMP'

See the online help documentation for Table from SQL or Chart from SQL for detailed information.

Development Guidelines

Oracle recommends adhering to the following guidelines when defining the PL/SQL for a report definition file:

When Using Chart from SQL and Table from SQL elements

Recommended Coding Practice

When calling the PL/SQL API methods, you should use named notation rather than positional notation. If you have => in your call, you are using named notation. For example,

l_report_guid := mgmt_ip.create_report_definition (
     p_title_nlsid                => 'Org breakdown by title (oracle_orgchart)',
     p_description_nlsid          => 'Charts showing the breakdown by title',
     p_owner                      => mgmt_user.get_repository_owner,
     p_category_nlsid             => 'Test Org Chart Reports',
     p_sub_category_nlsid         => 'Interesting Org Data',
     p_late_binding_target_types  => l_target_type,
     p_late_binding_multi_targets => 0,
     p_show_table_of_contents     => 0,
     p_system_report              => 1,
     p_component_name             => 'oracle_orgchart'
     );

Using named notation insulates your report definition from any code changes to future releases of the PL/SQL API and also helps make your code self-documenting.
