VALIDATE_INDEX
Provides diagnostics if index corruption is believed to have occurred. CTX_REPORT.VALIDATE_INDEX checks an index (or a partition for a locally partitioned index) and reports whether or not any corruption has been detected. VALIDATE_INDEX only checks $I rows that have token_type 0 and does not check other rows that contain information about sections, such as the NDATA section.
This procedure is primarily intended as a diagnostic tool to be used under the direction of Oracle Support.
