CAUSE
This is is a known and common problem hit in 10.2.0.5, investigated and corrected in unpublished Bug 7612454. The problem was introduced in 10.2.0.5, by the fix of Bug:7523755.
This has been corrected in PSU 10.2.0.5.4 and 11.2. Please refer to:
Note 7612454.8 - Bug 7612454 - More "direct path read" operations / OERI:kcblasm_1 CHANGES
This problem is hit only in 10.2.0.5, up to PSU 10.2.0.5.4 in which problem is fixed.
Problem is affecting 10.2.0.5 to 10.2.0.5.3. SOLUTION
The quickest way to solve the problem is to apply PSU 10.2.0.5.4, Patch 12419392 or later.
All alternative solutions for this problem are listed below:
Upgrade the database to 11.2.
- OR -
Apply 10.2.0.5.4 Patch Set Update (Patch 12419392) or later PSUs where bug is fixed.
The available PSUs are mentioned in "10.2.0.5 Patch Set Updates - List of Fixes in each PSU" (Document 1337394.1)
- OR -
Apply interim Patch 7612454 on top of 10.2.0.5 (10.2.0.5.0-10.2.0.5.3):
For UNIX / Linux platforms apply Patch 7612454 available for download on MOS.
For Windows platforms apply Patch 3 or higher.
Please check Document 342443.1 for latest patches available for Windows on top of 10.2.0.5.
解决方案：1.升级数据库版本-11.2
2.patch 12419392 apply 10.2.0.5.4
3. patch 7612454 on top of 10.2.0.5 (10.2.0.5.0-10.2.0.5.3):

4.0 分析结论
问题分析后，此ora-600为一个bug，遭遇此报错的是一个pl/sql 开发人员，且写的sql效率非常低，非业务sql，因此此报错可忽略。 如果是业务sql频繁报错，可能计划打补丁；
本次建议，让开发人员对此sql进行优化处理，sql的查询逻辑是否有改进的空间。
