ALL_IND_PARTITIONS
describes, for each index partition accessible to the current user, the partitionlevel partitioning information, the storage parameters for the partition, and various partition statistics collected by ANALYZE
statements.
DBA_IND_PARTITIONS
describes all index partitions in the database.
USER_IND_PARTITIONS

VARCHAR2(3) 
Indicates whether the partition belongs to a local index on a compositepartitioned table (YES ) or not (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

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 the partition 
COMPRESSION 
VARCHAR2(8) 
Indicates whether key compression is enabled for a partitioned index (ENABLED ) or not (DISABLED ); 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

DISTINCT_KEYS 
NUMBER 
Number of distinct keys in the index partition 
AVG_LEAF_BLOCKS_PER_KEY

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.

Indicates whether 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)
