OBIEE 11g Usage Tracking

Checking for Usage Tracking Table

In this sub-section, you check for the existence of the S_NA_ACCT Usage Tracking table in the database Repository Creation Utility (RCU) schema. In this example, the data source name is orcl, the schema name isdev_biplatform, and the password is Oracle01. Open SQL*Plus on your desktop. Log in with the user name dev_biplatform and password Oracle01.

At the SQL prompt, enter the following SQL statement:

SQL>Select table_name from tabs where table_name like 'S%';

Check the columns names by entering the following statement:

SQL>Desc S_NQ_ACCT;

You can also use SQL Developer to check for the S_NQ_ACCT table.

Creating the Database Object in the Physical Layer

Open SampleApp.rpd in offline mode in the BI Administration Tool. This is the rpd that comes with the Sample Applications. Enter Admin123 as the repository password.

Right-click 13-Usage Tracking 2 and select New Object>Logical Table.

Name the table Measures and click OK.

Repeat and add three more tables - Time, Topic, and User to the 13-Usage Tracking 2 business model.

Drag the following three physical columns from Usage Tracking Schema>S_NQ_ACCT to the Measures logical table in the 13- Usage Tracking 2 business model. For each column, right-click the logical column and select Rename, and then rename as follows:

Physical Column	Rename
QUERY_TEXT	Query Count
ROW_COUNT	Row Count
TOTAL_TIME_SEC	Total Time Seconds

Right-click the column Query Count and select Properties.

Click the Aggregation tab and select Count from the Default aggregation rule drop-down list. Click OK.

Similarly, set the Aggregation rule for other logical columns in the Measures logical table as follows:

Logical Column	Aggregation Rule
Row Count	Sum
Total Time Seconds	Sum

Drag the following three physical columns from Usage Tracking Schema>S_NQ_ACCT to the Time logical table in the 13-Usage Tracking 2 business model. Rename them as follows:

Physical Column	Rename
START_DT	Start Date
START_HOUR_MIN	Start Hour Minute
END_HOUR_MIN	End Hour Minute

The Time logical table should look like this:

Set Start Date as the logical key for the Time logical table. Right-click the Time logical table and select Properties.

Click the Keys tab and enter Time_key in the Key Name column.

Select Start Date from the Columns drop-down list. Click OK.

Drag the following two physical columns from Usage Tracking Schema>S_NQ_ACCT to the Topic logical table in the 13-Usage Tracking 2 business model. Rename them as follows:

Physical Column	Rename
QUERY_TEXT	Logical SQL
SUBJECT_ AREA_NAME	Subject Area

Set Logical SQL as the logical key for the Topic logical table.

Drag the USER_NAME physical column from Usage Tracking Schema>S_NQ_ACCT to the User logical table in the 13-Usage Tracking 2 business mode. Rename it to User Name.

Set User Name as the logical key for the User logical table.

Use the Business Model Diagram to create logical joins from Measures to Time. Right-click the 13-Usage Tracking 2 business model and select Business Model Diagram>Whole Diagram.

Click the New Join icon from the menu and create logical joins from Measure to Time, Topic, and User as shown below. Close the diagram.

You have now created the Usage Tracking business model. You will next move it to the Presentation layer.

Creating the Presentation Layer

Drag the 13-Usage Tracking 2 business model to the Presentation layer to create the Presentation layer objects. Rename the subject area to Y-Usage Tracking 2.

Save the repository. A message will ask whether you want to check consistency. Click Yes. You should then receive a message stating - Business model 13-Usage Tracking 2 is consistent. Do you want to mark it as available for queries? Click YES. The Consistency Check Manager window is displayed.

Click Close in the Consistency Check manger. Close the repository and the BI Administration Tool.

You have now finished creating the Y-Usage Tracking 2 subject area. Note: In Sample Applications, there is another usage tracking subject area name U - Usage Tracking.

Configuring Usage Tracking in Enterprise Manager

You now configure usage tracking through Oracle Enterprise Manager (EM) by performing the following steps:

Log into EM. In this example, the user name is weblogic and the password is welcome1.

Select WebLogic Domain>bifoundation_domain from the left navigation pane.

Click the WebLogic Domain drop-down list in the right pane.

Select System MBean Browser from the list.

Expand Application Defined MBeans>oracle.biee.admin.

Expand bifoundation_domain.

Lock the domain to update it. Expand BIDomain and select the BIDomain MBean where group=Service. Note: Expand Show MBean Information in the right pane.

Click the Operations tab.

Click the Lock link. On the Operation:lock page, click the Invoke button.

Click the Return button.

Expand BIDomain.BIInstance.ServerConfiguration, and then select the BIDomain.BIInstance.ServerConfiguration MBean.

Click the Attributes tab. Scroll down and click UsageTrackingCentrallyManaged. Set Value to true in the drop-down list.

Click the Apply button. When you see the confirmation message for the update, click the Return button.

Similarly, set the UsageTrackingEnabled attribute to true to enable usage tracking.

Set the UsageTrackingDirectInsert attribute to true to enable direct insertion.

Set the UsageTrackingPhysicalTableName attribute to the name of the fully qualified database table for collecting query statistic information, as it appears in the Physical layer of the Oracle BI repository. In this example, it is set as follows:

"12-Usage Tracking"."Usage Tracking Schema"."S_NQ_ACCT"

Set the UsageTrackingConnectionPool attribute to the name of the fully qualified connection pool for the query statistics database, as it appears in the Physical layer of the Oracle BI repository. In this example, it is set as follows:

"12-Usage Tracking"."UsageTracking Connection Pool"

Note: For usage tracking insertions to succeed, the connection pool must be configured with a user ID that has write access to the back-end database. Also, it is recommended that the connectivity type support international data.

After applying your changes, release the lock on the domain, as follows:

• Return to the BIDomain MBean where group=Service under oracle.biee.admin, Domain:bifoundation_domain, BIDomain.
• Click the Operations tab.
• Click the first commit operations.
• Click Invoke.
• Click Return.

Go to the Oracle Business Intelligence Instance page and click Restart All on the Availability>Processes tab.

Populating the Usage Tracking Table and Verifying Usage Tracking
