NUMBER

 

Length of the partition bound value expression

PARTITION_POSITION

NUMBER

 

Position of the partition within the index

STATUS

VARCHAR2(8)

 

Indicates whether the index partition is usable (USABLE) or not (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

MAX_SIZE

NUMBER

 

Maximum number of blocks 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)

 

Indicates whether or not changes to the index are logged:

  • NONE - Not specified

    See Also: the *_IND_SUBPARTITIONS view

  • YES

  • NO

COMPRESSION

VARCHAR2(13)

 

Indicates whether index compression is enabled or disabled for a partitioned index; NULL for a nonpartitioned index:

  • NONE - Not specified

    See Also: the *_IND_SUBPARTITIONS view

  • ENABLED

  • DISABLED

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

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:

  • DEFAULT

  • KEEP

  • RECYCLE

  • NULL

FLASH_CACHE

VARCHAR2(7)

 

Database Smart Flash Cache hint to be used for partition blocks:

  • DEFAULT

  • KEEP

  • NONE

Solaris and Oracle Linux functionality only.

CELL_FLASH_CACHE

VARCHAR2(7)

 

Cell flash cache hint to be used for partition blocks:

  • DEFAULT

  • KEEP

  • NONE

See Also: Oracle Exadata Storage Server Software documentation for more information

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 index-organized table, the percentage of rows with VALID guess

GLOBAL_STATS

VARCHAR2(3)

 

GLOBAL_STATS will be YES if statistics have been gathered or NO if statistics have been aggregated from subpartitions or have not been gathered

DOMIDX_OPSTATUS

VARCHAR2(6)

 

Status of the operation on a domain index:

  • NULL - Index is not a domain index

  • VALID - Operation performed without errors

  • FAILED - Operation failed with an error

PARAMETERS

VARCHAR2(1000)

 

For a domain index, the parameter string

INTERVAL

VARCHAR2(3)

 

Indicates whether the partition is in the interval section of an interval partitioned table (YES) or whether the partition is in the range section (NO)

SEGMENT_CREATED

VARCHAR2(3)

 

Indicates whether the index partition segment has been created (YES) or not (NO); N/A indicates that this index is subpartitioned and no segment exists at the partition level

ORPHANED_ENTRIES

VARCHAR2(3)

 

Indicates whether a global index partition contains stale entries because of deferred index maintenance during DROP/TRUNCATE PARTITION, or MODIFY PARTITION INDEXING OFF operations.

Possible values:

  • YES - the index partition contains orphaned entries

  • NO - the index partition does not contain orphaned entries
