1. A method for distributing data of a database to table space containers as a function of active and inactive node designations, the method comprising: in response to integrating a relational database on at least one physical server, a processor creating a plurality of active logical nodes and a plurality of inactive logical nodes; the processor creating database node groups by marking the active nodes as available for use in data storage and distribution and marking the inactive nodes as unavailable for use in data storage and distribution; the processor creating table space for the relational database by defining containers for each of the active and inactive nodes; in response to a request to increase data capacity in the relational database, altering at least one of the created database node groups by selecting and activating one of the inactive nodes into an activated node; in response to the activating of the selected inactive node into the activated node, altering the table space by activating the defined container that is associated with the activated node; and automatically re-balancing table data of the relational database across the table space active containers and the activated defined container that is associated with the activated node in response to the step of activating the defined container, wherein the table data is accessible to a user of the database during the re-balancing the table data.
