Purpose

The error is raised when we fail to find a row piece, i. e., the block is fine, but the row does not exist.
This error is new in 10g, in 9i we didn't raise this error and the corruption was unnoticed.


We raise ORA-600[kdsgrp1] assert during table/index full scans if a row piece is not found.
The error is raised only if Event 10231 or SKIP_CORRUPT_BLOCKS is not set.

/* Check table number, whether the row slot exists, whether row exists */
/* if row doesn't exist, and neither 'skip corrupt block' nor
** 'user rowid' bits are set, then raise error kdsgrp1.

Note: the block is good and because of that DBV, RMAN, analyze will not fail.
