When a database error occurs because of invalid connections, the EventReader continuously polls the database until the connection is restored. This handling is especially required during shutdown initiation of the Event Publisher while it is polling the database.
EventReader stops the Event Publisher for any other database errors.
When EventReader stops due to unrecoverable database errors, we recommend you look at the log file for detail error messages, and correct them manually. For example, the error may occur because of an invalid JMS configuration or restricted access permission to JMS destinations. In these cases you must modify the required configuration.
