INDEX_OWNER

VARCHAR2(30)

Owner of the index

INDEX_NAME

VARCHAR2(30)

Name of the index

COMPOSITE

VARCHAR2(3)

Whether the partition belongs to a local index on a compositepartitioned table (YES  NO )

PARTITION_NAME

VARCHAR2(30)

Name of the partition

SUBPARTITION_COUNT

NUMBER

If a local index on a compositepartitioned table, the number of subpartitions in the partition

HIGH_VALUE

LONG

Partition bound value expression

HIGH_VALUE_LENGTH

NUMBER

Length of partition bound value expression

PARTITION_POSITION

NUMBER

Position of the partition within the index

STATUS

VARCHAR2(8)

Whether index partition is USABLE or UNUSABLE

TABLESPACE_NAME

VARCHAR2(30)

Name of the tablespace containing the partition

PCT_FREE

NUMBER

Minimum percentage of free space in a block

INI_TRANS

NUMBER

Initial number of transactions

MAX_TRANS

NUMBER

Maximum number of transactions

INITIAL_EXTENT

NUMBER

Size of the initial extent in bytes

NEXT_EXTENT

NUMBER

Size of secondary extents in bytes

MIN_EXTENT

NUMBER

Minimum number of extents allowed in the segment

MAX_EXTENT

NUMBER

Maximum number of extents allowed in the segment

PCT_INCREASE

NUMBER

Percentage increase in extent size

FREELISTS

NUMBER

Number of process freelists allocated in this segment

FREELIST_GROUPS

NUMBER

Number of process freelist groups allocated in this segment

LOGGING

VARCHAR2(7)

Logging attribute of partition

COMPRESSION

VARCHAR2(8)

Indicates whether key compression is ENABLED or DISABLED for a partitioned index. NULL for a nonpartitioned index.

BLEVEL

NUMBER

B*Tree level: depth of the index from its root block to its leaf blocks. A depth of 0 indicates that the root block and leaf block are the same.

LEAF_BLOCKS

NUMBER

Number of leaf blocks in the index partition

DISTINCT_KEYS

NUMBER

Number of distinct keys in the index partition

AVG_LEAF_BLOCKS_PER_KEY

NUMBER

Average number of leaf blocks in which each distinct value in the index appears, rounded to the nearest integer. For indexes that enforce UNIQUE and PRIMARY KEY constraints, this value is always 1 .

AVG_DATA_BLOCKS_PER_KEY

NUMBER

Average number of data blocks in the table that are pointed to by a distinct value in the index rounded to the nearest integer. This statistic is the average number of data blocks that contain rows that contain a given value for the indexed columns.

CLUSTERING_FACTOR

NUMBER

Indicates the amount of order of the rows in the table based on the values of the index.
 If the value is near the number of blocks, then the table is very well ordered. In this case, the index entries in a single leaf block tend to point to rows in the same data blocks.
 If the value is near the number of rows, then the table is very randomly ordered. In this case, it is unlikely that index entries in the same leaf block point to rows in the same data blocks.

NUM_ROWS

NUMBER

Number of rows returned by the ANALYZE statement

SAMPLE_SIZE

NUMBER

Sample size used in analyzing this partition

LAST_ANALYZED

DATE

Date on which this partition was most recently analyzed

BUFFER_POOL

VARCHAR2(7)

Actual buffer pool for the partition

USER_STATS

VARCHAR2(3)

Indicates whether the statistics were entered directly by the user (YES ) or not (NO )

PCT_DIRECT_ACCESS

NUMBER

If a secondary index on indexorganized table, the percentage of rows with VALID guess

GLOBAL_STATS

VARCHAR2(3)

Indicates whether statistics for the partition were collected for the partition as a whole (YES ) or were estimated from statistics on underlying subpartitions (NO ).

DOMIDX_OPSTATUS

VARCHAR2(6)


PARAMETERS

VARCHAR2(1000)
