This section describes how to change AppServer broker controls.

  2. Click Broker Control in the Command and control section to display the Broker Control page, as shown:
  3. This following table highlights the controls that you can change in the Broker Control page settings:

    (A checkmark displays to indicate that the Enabled property is set. To clear this option, click the checkmark.)
    Click Edit. Then select or clear the Enabled property.
     
    You must also restart the AppServer broker so that the property change is recognized.
    Change the current setting of the Broker statistics available property displayed in the Broker summary section of the Broker Control page.
    Toggle between stopping and starting the AppServer broker, depending on the current value displayed in the Status field.
    For example, if the broker status currently displays ACTIVE, the button label will read Stop AppServer. Click this button to stop the AppServer broker. OpenEdge Management stops the broker and updates the value in the Status field to display Not Running.
    Click Stop AppServer or Start AppServer.
    Exit this page without changing any values. The AppServer main page redisplays in the management console.
    Click Cancel.

Data collection details

Data collection ensures that broker-related performance statistics can be trended to the OpenEdge Management Trend Database. Options and conditions available on the Broker Control page and the AppServer broker resource monitoring plan must be fulfilled to successfully implement data collection.

On the Broker Control page, these conditions include:

On the AppServer broker resource monitoring plan, you must also select the Trend Performance Data option.

Note: You are not required to use trending with the data collection activity. However, without the Trend Performance Data option selected, you cannot trend data. Data trended to the OpenEdge Management Trend Database is required for AppServer-related rule evaluation, graphical displays, and report generation.

For information about the Trend Performance Data option and monitoring plans for AppServer broker resources, see Chapter 6, "Monitoring Plans and Rules for OpenEdge Server Resources."

Note: Using data collection might cause the AppServer broker to exhibit some level of performance degradation, memory degradation, or both.

To set the options to perform data collection in an AppServer broker:

  1. Check the current status of the Collect Statistics field in the Properties section of the Broker Control page. The field must be selected to indicate that this property is set.
  2. If the Collect Statistics field is not checked, then click Edit. In the Collect Statistics field, click in the check box; a check mark appears. Click Save.

  3. Stop and restart the AppServer broker you want to update.
  4. Caution: You cannot interactively change a running process. Therefore, you must restart the AppServer broker after you change the setting of the Collect Statistics field.

    The Broker statistics available field in the Broker summary section will display True if the broker restarted successfully. The True value indicates that you have successfully set data collection and that broker statistical data is now available to be stored in the OpenEdge Management Trend Database.

  5. Check the current setting of the Trend field in the Properties section of the Broker Control page. The field must be selected to indicate that this property is set. See the "Default polling and trend values" section and the "Default monitoring plan details" section for details about this field.
