Configuring an indexing database

If you choose not to use the recommended Storage as a Service (STaaS) setup but instead choose self-hosted storage, you also need to set up an OpenSearch or Elasticsearch indexing database in your DMS.

An indexing database is required for many DataMiner features, including:


Elasticsearch is only supported up to version 6.8. As this version is no longer supported by Elastic, we recommend using OpenSearch instead.


For information on the system requirements for OpenSearch/Elasticsearch, refer to DataMiner Compute Requirements.

Dedicated clustered storage setup

In a dedicated clustered storage setup, an indexing database is required. Once you have set up Cassandra or a Cassandra-compatible database for the general system storage, you need to set up one of the following databases as the indexing database:


Amazon OpenSearch Service is also supported from DataMiner 10.3.0 [CU0] up to 10.3.0 [CU8] and from DataMiner 10.3.3 up to 10.3.11, but this is now deprecated.

Storage per DMA

While this is no longer recommended, it is still possible to use a self-hosted storage setup with a Cassandra database per DataMiner Agent. In such a setup, you should also install an OpenSearch or Elasticsearch indexing database in order to get access to additional DataMiner features, including User-Defined APIs, DOM, and SRM.

When the database has been deployed, you can configure the indexing settings in DataMiner Cube.
