   To Check the Business Event System Setup

• 1. Use a web browser to connect to the following URL:

 <webagent>/wf_setup.check_all

• Replace <webagent> with the base URL of the web agent configured for Oracle Workflow in your Web server. See: Setting Global User Preferences.

Attention: This URL accesses a secured page, so if you have not yet logged on as valid user in the current web session, you will be prompted to do so before the page appears. You must have workflow administrator privileges to access the Event Manager web pages.

Note: You can also access the Check Setup web page from the Oracle Workflow home page. See: Accessing the Oracle Workflow Home Page.

• 2. The Check Setup page appears, displaying the propagation settings and components for your local system.

• 3. Use the Database Init.ora Parameters region to verify your settings for the database initialization parameters related to AQ. The Check Setup page displays the actual value defined for each parameter as well as the minimum recommended value for Oracle Workflow.

• To modify any of these parameters when using Oracle8i, change the settings in the init.ora file for your database. Then you must restart your database to make the changes effective.

• If you are using Oracle 9i, you can either modify the parameters in the init.ora file and restart the database, or you can use the ALTER SYSTEM statement to dynamically modify the values for AQ_TM_PROCESSES and JOB_QUEUE_PROCESSES for the duration of the instance.

Note: Because the JOB_QUEUE_INTERVAL parameter is desupported in Oracle9i, the Check Setup page does not display this parameter if you are using Oracle9i, and you do not need to set a value for it.

Note: You can use another initialization parameter, EVENT, for detailed database level tracing of issues related to AQ. Add the following line to your init.ora file:

    event = "24040 trace name context forever, level 10"

Then restart your database to make this change effective. Be aware that using this parameter may generate large trace files.

• 4. Use the Database Links region to verify your database links. The Check Setup page displays the name and status of each database link that is referenced in an agent's address. You should create any required database links that do not yet exist. See: Creating Database Links.

Note: Ensure that the database link names used in your agents' addresses are exactly the same as the database link names specified when the database links were created.

• 5. Use the Local Agents region to verify the queues that are set up for the agents defined on your local system. The Check Setup web page displays the name and direction of each agent, the name of the queue assigned to the agent, whether or not the queue has been created, how many messages on the queue have been processed and are ready to be consumed, and how many messages are still waiting to be processed. You should create any required queues that do not yet exist. See: Agents and Setting Up Queues.

Note: In addition to Business Event System agents, the Local Agents region also displays the standard agent defined for the Notification Mailer SMTP queue, WF_SMTP_O_1_QUEUE. You can review the information for this agent to check the number of notification messages on the Notification Mailer queue. The WF_SMTP_O_1_QUEUE agent is not used by the Business Event System, however. See: Standard Agents.

• 6. Use the Listeners for Local Inbound Agents region to schedule listeners to receive inbound event messages. See: Scheduling Listeners for Local Inbound Agents.

• 7. Use the Propagations for Local Outbound Agents region to schedule propagations to send event messages. See: Scheduling Propagations for Local Outbound Agents.
