Application metadata must be set up for the ILM crawler batch process to successfully manage the lifecycle of the data. The key metadata infrastructure is related to setting up the value of the Maintenance Object (MO) Options types.
ILM Crawler Batch Control: This option identifies the batch control that is used to manage historic data. This process invokes the MO's ILM eligibility algorithm for entity instances whose retention period has elapsed.
ILM Retention Period in Days: This option is used by the base ILM crawler batch control. Use this option to override the default retention period defined in the ILM master configuration.
