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
describes the index partitions owned by the current user. This view does not display the INDEX_OWNER
column.
Column  Datatype  Description 

INDEX_OWNER 
VARCHAR2(30) 
Owner of the index 
INDEX_NAME 
VARCHAR2(30) 
Name of the index 
COMPOSITE 
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 
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 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 
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.

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 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)
