Actuate supports read-only operations on the cluster and volume metadata stored in the tables of the OOTB or other third-party database. Actuate does not support the addition, deletion, or modification of these metadata tables.

Actuate does permit the creation of additional indexes on these tables. For example, a customer can create an index on the job completion notices table to expedite database processing.

Actuate does not recommend any customization of the cluster schema. Any customization that the customer does on the volume schema must be redone when migrating to or reinstalling BIRT iHub. BIRT iHub does not track any database objects that a customer creates. Actuate reserves the right to change the structure of the schemas in future releases.
