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
