INSTANCE_NUMBER
Value: 1-maximum number of instances specified in CREATE DATABASE statement
Default: lowest available number
Specifies a unique number that maps the instance to one group of free space lists for each table created with the storage option FREELIST GROUPS. The INSTANCE option of the ALTER TABLE ALLOCATE EXTENT statement assigns an extent to a particular group of free lists. If INSTANCE_NUMBER is set to the value specified for the INSTANCE option, the instance uses that extent for inserts and updates that expand rows. INSTANCE_NUMBER is a Parallel Server parameter. Multiple instances must have different values.
