在Oracle 10.2.0.4 以后的平台,我们在使用数据泵导入物化视图时,可能会遇到如下错误:
...
ksedmp: internal or fatal error
ORA-7445: exception encountered: core dump [_intel_fast_memcpy.A()+10]
[SIGSEGV] [Address not mapped to object] [0x000000000] [] []
Current SQL statement for this session:
ALTER MATERIALIZED VIEW "MVIEW_OWNER"."MVIEW_NAME"COMPILE
----- PL/SQL Call Stack -----
object line object
handle number name
0xbe4518d0 2 anonymous block
导致该错误的是Oracle10.2.0.4 平台上的bug:Bug6074902.
解决方法:
(1) 安装Patch 6074902
(2) 升级数据库到10.2.0.5
MOS 文档:
DataPump Import (IMPDP) Fails With ORA-7445[_INTEL_FAST_MEMCPY.A] While Importing Materialized Views [ID 867578.1]
