This section deals with the customer-specific database schemas.

You can create own database schemas in an SAP HANA database. However, they are different from SAP HANA Deployment Infrastructure (HDI) containers. If you only work with HDI containers as described in Migration of Native SAP HANA Database Objects, no further action is required.

As described in Technical Details of the Zero Downtime Option, the database schema changes during the rollover to the bridge subsystem. This change also implies a change of the database schema user that is used by the work processes.

To access the custom database schema from the bridge subsystem, make sure that the schema user of the bridge subsystem (for example, SAPHANADBSHD) has the same authorizations as the original schema user (such as SAPHANADB) before entering the bridge subsystem.
