做数据库同步实验的时候创建prebuilt mv 时 总是提示 ora-32349 ,查询metalink后,发现这是一个bug。。。。
yang@rac1>create materialized view yangtab2
  2   on prebuilt table refresh fast
  3   as select * from yangtab2@linkyang;
 create materialized view yangtab2
       *
ERROR at line 1:
ORA-32349: cannot reference prebuilt table in definition query for materialized view

yang@rac1>alter table yangtab2 add constraint pk_yangtab2 primary key (id);
Table altered.
yang@rac1>create materialized view yangtab2

  BUG TYPE CHOSEN
  ===============
  Code
  SubComponent: Materialized Views
  ================================
  DETAILED PROBLEM DESCRIPTION
  ============================
  The ability to create an materialized view on prebuilt table with the same
  name as a remote table exists in 9i, 10g, and 11R1, but does not exist in
  11R2, hence the creation of this bug for 11R2.
  Test scenario:  
  Create table as user ABC in 9i database, and as user ABC in 11R2 database
  (tested in 9.2.0.8 and 11.2.0.1):
  CREATE TABLE TEST
  ( ID NUMBER,
  VAL NUMBER,
  VAL2 VARCHAR2(30),
  VAL3 CLOB,
  PRIMARY KEY (ID));
 
  Create database link (tested private dblink for user ABC, connecting to ABC
  in remote db) from 11R2 to 9i.
  Create database link (tested private dblink for user ABC, connecting to ABC
  in remote db) from 9i to 11R2.
  In 9i, as user ABC, issue:
  CREATE MATERIALIZED VIEW TEST ON PREBUILT TABLE FOR UPDATE AS SELECT * FROM
  TEST@;
  Materialized view created.
  -  Note that the mview/prebuilt table have the same name/same schema as the
  remote table in select clause of definition query
  -  You can do the above test above in 10g and 11R1, and you will be able to
  successfully create the mview.
  -  Please also note that you can successfully create the mview if the Test
  table exists locally but in a different schema.
 
  Drop the mview, then do the following: 
  In 11R2, as user ABC, issue:
 
  CREATE MATERIALIZED VIEW TEST ON PREBUILT TABLE FOR UPDATE AS SELECT * FROM
  TEST@STRM92P
       *
  ERROR at line 1:
  ORA-32349: cannot reference prebuilt table in definition query for
  materialized view
  -  This error is returned for this test in 11R2 only.
 
  Note that Bug 6815375 addressed an ORA-4020 returned on creation of mview
  with prebuilt table where prebuilt table is referenced as local table in
  definition query.  This bug was resolved with return of ORA-32349 for
  action.  Unfortunately, this error is now returned on mview with prebuilt
  table where prebuilt table is referenced as remote table in definition query
  (where the ORA-4020 did not occur in prior releases). 
  DIAGNOSTIC ANALYSIS
  ===================
  See above 
  WORKAROUND?
  ===========
  Yes 
  WORKAROUND INFORMATION
  ======================
  Create prebuilt table using different name as remote table in definition
  query.  However, for customer of this bug, plan is to drop mview in future
  with resultant change of prebuilt table to regular table - customer wants
  this table to have same name as remote table.  This is a reasonable request,
  as this worked previously without ORA-4020 or other error.
 
  TECHNICAL IMPACT
  ================
  See above
  RELATED ISSUES (bugs, forums, RFAs)
  ===================================
  Bug 6815375 - ATTEMPT TO CREATE A MV WITH 'ON PREBUILT TABLE' RESULTS IN A
  DEADLOCK
  HOW OFTEN DOES THE ISSUE REPRODUCE AT CUSTOMER SITE?
  ====================================================
  Always
 
  DOES THE ISSUE REPRODUCE INTERNALLY?
  ====================================
  Always
  IS A TESTCASE AVAILABLE?
  ========================
  Yes
