title: Oracle 11gR2 MView refresh failing
body: <p>Hi I have created 5 MViews for tables in Remote DB 2 days back in production environment. Out of that one Mview, at the time of creation it worked fine. But 2 days after(today) the MView's last refresh date is still showing the day before yesterday's date.</p>
  
  <ol>
  <li>I checked on the DBA_JOBS:
  LAST_DATE,NEXT_DATE,BROKEN,INTERVAL,FAILURES,WHAT
  NULL,"23-JUL-13 01:00:00", N,"trunc(SYSDATE+1)+1/24",12,"dbms_refresh.refresh('"OCCSS_ENTMT_HK"."MV_SCI_STD_CODE_VALUE"');"</li>
  </ol>
  
  <p>MView create statement:</p>
  
  <pre><code>CREATE MATERIALIZED VIEW MV_SCI_STD_CODE_VALUE   BUILD IMMEDIATE   USING INDEX   REFRESH FORCE ON DEMAND START WITH SYSDATE+0 NEXT TRUNC(SYSDATE+1)+1/24   WITH PRIMARY KEY USING DEFAULT LOCAL ROLLBACK SEGMENT   USING ENFORCED CONSTRAINTS DISABLE QUERY REWRITE   AS SELECT STV_STD_CODE_NUM STANDARD_CODE,
      STV_STD_CODE_VALUE STANDARD_CODE_VALUE,
      STV_STD_CODE_VALUE_DESC DESCRIPTION,
      stv_prnt_std_code_value parent_code   FROM SCIADMIN.P03_STD_CODE_VALUE@SCI_LINK02.HK.BT.COM P03   WHERE STV_STD_CODE_NUM    IN ('19','31','54','5','6','300')   AND p03.update_status_ind &lt;&gt; 'D';
  
     COMMENT ON MATERIALIZED VIEW MV_SCI_STD_CODE_VALUE  IS 'snapshot table for snapshot MV_SCI_STD_CODE_VALUE';
  </code></pre>
  
  <p>The Mview is scheduled to run once in one day. But the failures shown is 12.</p>
  
  <ol>
  <li>I couldn't find any jobs for the above in DBMS_JOBS_RUNNING.</li>
  </ol>
  
  <p>I need to investigate this issue. What would be the possible issues which could have caused this failure?</p>
