Administrator Tasks for Blacklisting

Activating and Deactivating Blacklisting

Blacklisting is activated by default.

To activate or deactivate blacklisting, perform the following steps:

1. Start SAP NetWeaver Administrator and choose  Configuration  Infrastructure .

2. Choose Java System Properties .

   An overview of properties is displayed.

3. Go to the Services tab.

4. Locate the service XPI Service Messaging System .

   The parameters for this service are displayed.

   A boolean service property messaging.blacklisting.enabled controls blacklisting.

   By default, messaging blacklisting is enabled. (The parameter value is true .)

   The parameter is modifiable online. This means that you can apply a new value without restarting the server.

5. Choose Modify .

   A dialog box is displayed.

6. To deactivate blacklisting, specify false .

   To restore to the default value ( true ), choose Restore to default .

7. Save.

   A message confirms that changes were saved.

Manually Restarting Blacklisted Messages

If a message has not been processed, this may be because it has been blacklisted. A message that has been blacklisted and assigned state NDLV can still reenter processing if it is restarted. You can manually resend or redeliver a blacklisted message.

To check whether messages were blacklisted, perform the following steps:

1. Access the message monitor and switch to advanced search mode. For more information, see Monitoring Messages .

2. Select the checkbox for the Technical Attributes section, and then select the Blacklisted checkbox. For more information, see Advanced Message Search .

3. Enter other search parameters as necessary and start the search.

4. If the search yields any results, select a message and do one or more of the following:

   • Choose the Message Log tab to see the events that happened during the processing of the selected message.

     For more information, see the example below.

   • Stop or restart the message using the corresponding buttons. For more information, see Reviewing Search Results .

     Note

     You can restart all the blacklisted messages at once. However, be aware that this may be dangerous because blacklisted messages could potentially cause a server crash.

Configuring the Restart Job

A restart job restarts messages that have not been delivered (state NDLV). To set a job to restart blacklisted messages, perform the following steps:

1. Access the background processing monitor. For more information, see Performing Background Processing .

2. Create a new restart job, or choose an existing restart job. For more information, see Scheduling Jobs .

3. Select the job in the list, choose Edit , and then choose the Parameters tab.

4. In the Parameters dropdown menu, select RESTART-BLACKLISTED and choose Add .

5. When the system displays the selected parameter in the table, enter True in the Value column.

6. Add other parameters or rules as necessary. For more information, see Defining Rules .

7. Save the job.

   If the job is set to be active, the system runs it at the specified schedule and restarts the messages for which the job applies. You can also run it manually when necessary using the Execute Now button.
