Prerequisites

The Structure linkdatabase instance is in the ONLINE Structure linkoperational state.

The value of the database parameter for the volume type is equal at least to the total of existing and planned Structure linkvolumes.

Note

The system checks that there is enough space available for at least one volume of each type before each start of the database instance. If there is not, it automatically increases the setting of the appropriate database parameter by 1.

If you wish to enlarge the database instance by more than one volume of a type, adjust the relevant parameter accordingly (Defining Volume Parameters). Later on, this enables you to add a volume of the given type a number of times in succession with the database instance in the ONLINE operational state without having to stop the database instance.
