その中portaldb1_ora_40698472_i642694.trcファイルの文を確認してください。それが原因かもしれないから。Trcファイルとこのテーブルを開發者に渡した。

Format: ORA-600 [6749] [a]

VERSIONS:
versions 7.3 to 8.1

DESCRIPTION:

This internal occurs during the row change for update or delete.
Some reported problems are consistent read issue, some bugs are related to
row corruption on the block.

FUNCTIONALITY:
ROW DELETE

IMPACT:
PROCESS FAILURE
ROW CORRUPTION
[6749], [3], [37923665], [163], [], [], [], [], [], [], [], []
3は row no longer exists 行が存在していないと意味している

37923665 はdba
C は行のslot number

11.2.0.3 で該当するBugがないから、そのテーブルに対してANALYZE TABLE <table_name> VALIDATE STRUCTURE CASCADEする;そしてflush buffer_cacheする;エラがまだ残っていれば、テーブルを再構造してください。
7705591 Corruption with self-referenced row in MSSM tablespace. Wrong Results / OERI[6749] / ORA-8102
