7.3.1 Using Fusion Middleware Control to Disallow RPD Updates

You can use Fusion Middleware Control to allow or disallow updates to the default repository file. Setting this parameter affects whether you can update the repository when the Administration Tool connects in both online and offline mode. It also affects whether you can perform other repository update operations using other utilities, such as biserverxmlcli. Note that aggregate persistence feature is not available when repository updates are disallowed. Disallowing repository updates can improve Oracle BI Server performance, because in this mode, the Oracle BI Server does not need to handle lock control. If you choose to disallow repository updates, then when the Administration Tool opens a repository in either online or offline mode, a message informs the user that the repository is read-only. Before you begin this procedure, ensure that you are familiar with the information in Section 3.2, Using Fusion Middleware Control to Update Oracle Business Intelligence Configuration Settings. To use Fusion Middleware Control to disallow repository updates: 1. Go to the Business Intelligence Overview page, as described in Section 2.2.2, Using Fusion Middleware Control to Manage Oracle Business Intelligence System Components. 2. Display the Performance tab of the Capacity Management page.

3. Click Lock and Edit Configuration to allow changes to be made.

4. Select Disallow RPD Updates to disallow updates to the repository file.

7.3.4 Using Fusion Middleware Control to Set the Maximum Number of Rows Processed to Render a Table

You can override the maximum number of rows that can be fetched and processed from the Oracle BI Server for rendering a table. Reducing the number of rows in a table can significantly improve performance by reducing the system resources that can be consumed by a given user session. Advanced configuration settings are described in Section 18.3, Configuring for Displaying and Processing Data in Views.
