How can i find the unusable date of indexes, index partitions and index subpartitions , only with sqlplus , not looking in the alert log.

- How can i know the date that the status of an index partition has became unusable ?
- How can i know the date that the status of an index sub-partition has became unusable ?

Unless you are auditing DDL changes, then you will not be able to find the *date* at which this occurred.

Obviously the *current* status can be found simply by querying

xxx_INDEXES
xxx_IND_PARTITIONS
xxx_IND_SUBPARTITIONS

but if you want to capture the *when*, you'll need some auditing.

If the status is *currently* UNUSABLE, you could use LAST_DDL_TIME on xxx_OBJECTS as a *possible* time of status change.
