Last updated on SEPTEMBER 25, 2023

Applies to:

Oracle Database - Enterprise Edition - Version to [Release 9.0.1 to 11.2]
Information in this document applies to any platform.


Chained rows become logically corrupted via the pointer to the next row piece being wrongly updated to point to the current row piece, thereby creating a circular reference.  If indices are not in place, the corruption may become a true data corruption as further updates will update the wrong column.
