G |
| GROUP_MEMBER | CHAR(8)

| LOWDSNUM | INTEGER
NOT NULL WITH DEFAULT |
Partition number of the lowest partition in the range for SYSCOPY records created for REORG and LOAD REPLACE for resetting a REORG pending status. Version number of an index for SYSCOPY records created for a COPY (ICTYPE=F) of an index space (OTYPE=I). (An index is versioned when a VARCHAR column in the index key is lengthened.) When ICTYPE = F or I, DSNUM = 0 and OTYPE is not equal to I, LOWDSNUM = 1. | G |
| HIGHDSNUM | INTEGER
NOT NULL WITH DEFAULT |
Partition number of the highest partition in the range. This column is valid only for SYSCOPY records created for REORG and LOAD REPLACE for resetting REORG pending status.When ICTYPE = F or I, DSNUM = 0 and OTYPE is not equal to I, HIGHDSNUM is the number of the highest partition that is copied. | G |

MEMBER CLUSTER attribute is being used:

a change that was applied to the hash organization of the table:
|
G |
| TTYPE (continued) | When ICTYPE=A

LOB column was altered:
When ICTYPE=A
and STYPE=M, this column indicates either the previous value of
the MAXPARTITIONS attribute for the table space or the type of table
space conversion that was performed on the table space.
|
||
| TTYPE (continued) | When ICTYPE=A
and STYPE=S, this column indicates either the previous value of
the SEGSIZE attribute for the table space or the type of table space
conversion that was performed on the table space.

When ICTYPE=Y or Z, this column indicates whether the object was loaded when the FORMAT INTERNAL option was specified.
|
||
| INSTANCE | SMALLINT
NOT NULL WITH DEFAULT 1 |
When STYPE = E and ICTYPE = A, INSTANCE indicates
the data set instance number of a base object after an EXCHANGE statement
completes. The value of the INSTANCE column for the last data exchange
