Enabling and disabling the CEI store

The emission of events from the runtime engine to the WebSphere® Business Monitor occurs as message transmissions using the Common Event Infrastructure (CEI).

There is an option in the CEI configuration to use CEI store or not. If this option is turned on, the CEI persists every message it receives before sending it to the Monitor Server. Enabling this option can serve as a backup in case of failures; lost messages can be recovered and sent again to the Monitor Server. On the other hand, the persistence of messages affects performance, resulting in a lower total throughput of events. You can choose to enable or disable this feature depending on the priority of performance against messages backup and also based on your hardware configuration. To enable this option:
  1. From the left pane of WebSphere Application Server administrative console, select Resources > Common Event Infrastructure Provider.
  2. Select the appropriate level. (If you are using default server settings, click Cell.)
  3. From Additional properties, click Event Server Profile.
  4. Click on the profile name you are using. (The default is Default Common Event Infrastructure server.)
  5. Select the Enable Data Store check box to enable this feature or clear the check box to disable the feature.
  6. Click OK and save your changes.
