Turning data row caching on or off

When the AEL is refreshed, event data in its rows is loaded from the cache if the refresh interval is less than 60 seconds. To have the event list refreshed from the database, turn data row caching off.

Before you begin

This function can also be performed in the Data Sources page.

About this task

To turn off data row caching:

Procedure

  1. Open the following file:

    ncwDataSourceDefinitions.xml
  2. Set the enabled attribute of the <eventList> element to false.
    For example:
    <eventList maxAge="60" enabled="false" cleantime="120" /> 
  3. Save and close the file.
  4. Restart the server.

Results

When the AEL is refreshed, data is drawn directly from the ObjectServer instead of the data cache.
