  2 record(s) selected.

The fields are identified as follows:

DATABASE PARTITION GROUP NAME

The name of the database partition group. The name is repeated for each database partition in the database partition group.

PMAP_ID

The ID of the distribution map. The ID is repeated for each database partition in the database partition group.

DATABASE PARTITION NUMBER

The number of the database partition.

IN_USE

One of four values:

Y: The database partition is being used by the database partition group.
D: The database partition is going to be dropped from the database partition group as a result of a REDISTRIBUTE DATABASE PARTITION GROUP operation. When the operation completes, the database partition will not be included in reports from LIST DATABASE PARTITION GROUPS.
A: The database partition has been added to the database partition group but is not yet added to the distribution map. The containers for the table spaces in the database partition group have been added on this database partition. The value is changed to Y when the REDISTRIBUTE DATABASE PARTITION GROUP operation completes successfully.
T: The database partition has been added to the database partition group, but is not yet added to the distribution map. The containers for the table spaces in the database partition group have not been added on this database partition. Table space containers must be added on the new database partition for each table space in the database partition group. The value is changed to A when containers have successfully been added.

Compatibilities

For compatibility with versions earlier than Version 8:

The keyword NODEGROUPS can be substituted for DATABASE PARTITION GROUPS.
