DBMS_REPAIR

DBMS_REPAIR contains data corruption repair procedures that enable you to detect and repair corrupt blocks in tables and indexes. You can address corruptions where possible and continue to use objects while you attempt to rebuild or repair them.

Note:
The DBMS_REPAIR package is intended for use by database administrators only. It is not intended for use by application developers.

The package is owned by SYS. Execution privilege is not granted to other users.

Enumeration Types

The DBMS_REPAIR package defines several enumerated constants that should be used for specifying parameter values. Enumerated constants must be prefixed with the package name. For example, DBMS_REPAIR.TABLE_OBJECT.

Table 36-1 lists the parameters and the enumerated constants.
