19-2 System Administrators Guide for Oracle Business Intelligence Enterprise Edition 19.2 How Do Antivirus Software and Privileges Affect Agents? This section provides the following information about agents: ■ Section 19.2.1, How Does Antivirus Software Affect Agents? ■ Section 19.2.2, What Privileges Affect Agents? 19.2.1 How Does Antivirus Software Affect Agents? Some antivirus software programs, such as Norton AntiVirus, enable a script-blocking feature, which tries to block all calls made by scripts to system objects such as the Windows file system object that the antivirus software deems unsafe. If you start a script as part of post-agent processing, then this antivirus feature might cause unexpected results. If you run antivirus software with a script-blocking feature on the computer where Oracle BI Scheduler is installed, then you should disable the script-blocking feature to prevent the software from unexpectedly blocking agent script calls. 19.2.2 What Privileges Affect Agents? You access the privilege settings for agents in the Delivers section of the Manage Privileges page in Oracle BI Presentation Services Administration. To create an agent, users must be granted the Create Agent privilege. To enable users with the Publish Agents for Subscription privilege, which provides the ability to change or to delete an agent, you must grant them the Modify permission to the shared agent objects and child objects in the Oracle BI Presentation Catalog. For information, see Managing Presentation Services Privileges in Oracle Fusion Middleware Security Guide for Oracle Business Intelligence Enterprise Edition.

19.3 Configuring Settings That Affect Agents

You configure settings for agents by changing values for Oracle BI Presentation Services or Oracle BI Scheduler. You configure delivery options for agents using the SA System subject area. This section contains the following topics: Note: If the Oracle BI Server is configured to authenticate users through database logons, then impersonation is permitted until the number of associated variables exceeds one for example, when session variables other than USER are associated with the initialization block. If the number of associated variables exceeds one, then the impersonated user does not have the password to log in to the database and to fill the other session variables. Agents work with database authentication, if only the initialization block that is set up for authentication in the Oracle BI Administration Tool uses a connection pool with pass-through login. That connection pool cannot be used for any other initialization block or request. For information about user authentication options, see Oracle Fusion Middleware Security Guide for Oracle Business Intelligence Enterprise Edition. For information about pass-through login, see Oracle Fusion Middleware Metadata Repository Builders Guide for Oracle Business Intelligence Enterprise Edition.

19.3.1 Manually Configuring Presentation Services Settings That Affect Agents

Use various elements in the instanceconfig.xml file for Presentation Services to change these settings. You must apply changes to both the primary and secondary schedulers instanceconfig.xml in a cluster. Before you begin this procedure, ensure that you are familiar with the information in Section 3.4, Using a Text Editor to Update Configuration Settings. To manually edit Presentation Services settings that affect agents: 1. Open the Presentation Services instanceconfig.xml file for editing, as described in Section 3.6, Where Are Configuration Files Located? 2. Locate the section in which you must add the elements that are described in Table 19–1 . 3. Include the elements and their ancestor elements as appropriate, as shown in the following example: ServerInstance ps:Alerts xmlns:ps=oracle.bi.presentation.servicesconfigv1.1 ps:Enabledfalseps:Enabled ps:DefaultDeliveryFormatpdfps:DefaultDeliveryFormat ps:Alerts ServerInstance

4. Save your changes and close the file.

5. Restart Presentation Services.

Table 19–1 Presentation Services Settings That Affect Agents Element Description Default Value Enabled Specifies whether Oracle BI Delivers is enabled. Allowed values are true or false. Delivers is an optional component of Presentation Services that is enabled by default for organizations that have purchased the appropriate license. You use the Delivers component to create agents. true
