Automatic FuzzyDB Learning

Overview

  • To use this feature with a given batch class, the batch class has to be added to the “fuzzydb.learndb.batchClassList” property in the fuzzy-db.properties file.
    • This is located at Ephesoft\Application\WEB-INF\classes\META-INF\dcma-fuzzydb\fuzzy-db.properties.
  • This feature is the automation of FuzzyDB learning. It performs the same function as is done by clicking on the Learn DB button. It creates Lucene indexes at regular intervals, eliminating the need to click Learn DB each time a change is made to the database.

Configure CronJob

Automatic FuzzyDB learning is performed at a regular interval, defined by a CronJob expression.

To configure the time interval, you will need to modify the “fuzzydb.learndb.cronjob.expression” property, located in the fuzzy-db.properties file. The value of this property is a cronjob expression.

Note: The default value for the “fuzzydb.learndb.cronjob.expression” property is <0 0 0 * * ?> This means the automatic FuzzyDB service is fired at 12AM every day.
