DEFERRED_SEGMENT_CREATION

Property Description
Parameter type Boolean
Default value true
Modifiable ALTER SESSION, ALTER SYSTEM
Range of values true | false
Basic No

DEFERRED_SEGMENT_CREATION specifies the semantics of deferred segment creation. If set to true, then segments for tables and their dependent objects (LOBs, indexes) will not be created until the first row is inserted into the table.

Before creating a set of tables, if it is known that a significant number of them will not be populated, then consider setting this parameter to true. This saves disk space and minimizes install time.
