Begin Time

The beginning of the last period when undo statistics were collected

End Time

The end of the last period when undo statistics were collected

Expired Blocks Removed

Number of expired undo blocks stolen from other undo segments

Expired Blocks Reused

Number of expired undo blocks reused within the same undo segments

Expired Blocks Steals

Longest Query SQL ID

SQL identifier of the longest running SQL statement within the specified time range

No Space Error Count

The number of times requests for space in the undo tablespace failed to find any free space available

SnapShot Too Old Error Count

The number of times the error ORA-01555 (snapshot too old) occurred

Transactions

The total number of transactions executed within the specified time range

Unexpired Blocks Removed

Number of unexpired blocks removed from certain undo segments so they can be used by other transactions

Autoextensible

Indicates whether the datafile is autoextensible

Current Retention

Specifies (in seconds) the low threshold value of undo retention

Minimum Required Undo Size

The minimum size (in megabytes) of undo space required. This value takes into account transactions rate, undo generation rate and current undo retention.

Optimal Retention

The optimal undo retention, taking into account undo generation rate and actual undo size

Retention Guarantee

Indicates the state of the Undo tablespace retention (GUARANTEE/NOGUARANTEE)

Retention value of GUARANTEE indicates that unexpired undo, in all undo segments in the undo tablespace, should be retained even at the cost of failure of forward-going operations that need to generate undo in those segments.
