Actuate BIRT iHub stores metadata containing information about the cluster and volume configurations in a relational database management system (RDBMS). In the default configuration, Actuate BIRT iHub uses the open-source, third-party database, PostgreSQL. iHub also supports using other alternative, third-party database systems, such as Oracle or a pre-existing PostgreSQL instance.
iHub stores metadata in the following schemas:
Cluster
