ORA-7445(kqlSubheapPin)错误

Oracle 10.2.0.4 for X86-64数据库出现ORA-7445[kqlSubheapPin]错误。
错误信息为:

Tue Jul 26 13:27:05 2011
Errors IN file /opt/app/oracle/admin/ora/udump/ora1_ora_6729.trc:
ORA-07445: exception encountered: core dump [kqlSubheapPin()+84] [SIGSEGV] [Address NOT mapped TO object] [0x000000110] [] []

根据MOS文档Bug 7280764 – Dump from concurrent CREATE MV and query rewrite or DDL [ID 7280764.8]的记录,这个bug是在创建物化视图日志的同时,对物化视图的基表执行了DDL操作,导致物化视图创建会话在一定时间内无法获取锁而导致的异常错误。
这个问题在10.2.0.4.3和10.2.0.5中被fixed,这个错误对数据库的影响不大,也不一定要通过补丁来解决该问题,在创建物化视图的时候避免对基表的操作就可以避免该错误的产生。
