SKIP_UNUSABLE_INDEXES

SKIP_UNUSABLE_INDEXES enables or disables the use and reporting of tables with unusable indexes or index partitions.

Values:

• true

  Disables error reporting of indexes and index partitions marked UNUSABLE. This setting allows all operations (inserts, deletes, updates, and selects) on tables with unusable indexes or index partitions.

  Note:

  If an index is used to enforce a UNIQUE constraint on a table, then allowing insert and update operations on the table might violate the constraint. Therefore, this setting does not disable error reporting for unusable indexes that are unique.

• false

  Enables error reporting of indexes marked UNUSABLE. This setting does not allow inserts, deletes, and updates on tables with unusable indexes or index partitions.
