物化视图快速刷新报 ORA-12008 & ORA-01031 ORA-12008 & ORA-01031 When Trying to do a Fast Refresh on an MView (文档 ID 810117.1)

In this Document

Symptoms Cause Solution References

APPLIES TO: Oracle Server - Enterprise Edition - Version 10.2.0.1 to 10.2.0.3 [Release 10.2] Information in this document applies to any platform. SYMPTOMS

The following error is raised when trying to perform a fast refresh of a Materialized View (MV):

ERROR at line 1: ORA-12008: error in materialized view refresh path ORA-01031: insufficient privileges ORA-06512: at "SYS.DBMS_SNAPSHOT", line 2255 ORA-06512: at "SYS.DBMS_SNAPSHOT", line 2461 ORA-06512: at "SYS.DBMS_SNAPSHOT", line 2430 ORA-06512: at line 1

The base table for the Materialized View contains XML or object types and is located in a different schema than the MV. If the same MV is created in the schema that owns the base table, then the refresh is working fine.

CAUSE

This issue is documented in Bug 6146742 and was confirmed for RDBMS versions 10.2.0.1 to 10.2.0.3.  It is caused by the internal use of the  'Flashback' feature of the database. Please see the Oracle documentation for more details on this feature.

The bug is currently open with Development and is being worked upon there.

SOLUTION

There is a workaround available to make the refresh run:

Granting explicitly  flashback privilege on the base table and the MV log to the owner of the MV avoids the issue:    Please replace 'PARENT_TABLE' with the name of the base table and '' with the owner of the Materialized View.
