table using a rowid that doesn't exist. eg.SELECT * FROM DUAL WHERE rowid = '0000000000000000'; This is a little counter-intuitive; you would expect No Rows Returned instead. When you do a MV Refresh, Oracle converts that request into a complex series of SQL statements that it performs in the background. If your MV is REFRESH FAST USING ROWID, or is a join-MV, then it is quite possible - nay likely - that one of the SQLs being performed in the background contains a WHERE ROWID = predicate. Now, I'll assume that it is a REFRESH FAST MV, because it is darned unlikely to happen with a complete refresh. Correct me if I'm wrong. Here's what I'd do: Try to change it to REFRESH FAST USING PRIMARY KEY rather than USING ROWID. If it is a join-MV without aggregates, you may not succeed. I can find nothing in the documentation about this, but I have not successfully created a non-aggregate-join-MV without including ROWID in the MV-logs. If the MV is refreshed using the PK, there will be no need to use ROWID's. This is not so much fixing the problem,

07, 2013 - 3:05 pm UTC Category: Database – Version: 9.2.0 Latest Followup You Asked Hi Tom, I was at your conference in MTL in february. It was a https://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:15695764787749 pleasure to finally meet you. My question is regarding the refresh of MVs. We are using Discoverer with a 9i Database in Archivelog mode. The problem is when we need to refresh our Materialized Views, a lot of redo logs are generated. It is somewhow strange to me since I though the refresh was done with an append hint. The Materialized error in views have been created with the NOLOGGING option. CREATE MATERIALIZED VIEW .... AS SELECT /* APPEND */... We are using the DBMS_MVIEWS.REFRESH procedure: exec DBMS_MVIEW.REFRESH('TBGADM.TBGADM_MV_44','C','',FALSE,FALSE,0,0,0,TRUE); This refresh generated around 679 MB of REDO (the MV weights around 200MB). How can we accomplish this refresh using less ARCHIVE LOGS? Can you shed some light on this? Rich and we said... If you error in materialized do incremental refreshes, the MV would be refreshed using conventional SQL. If this is a single table, complete refresh, it will use: truncate insert /*+ append */ which DOES NOT negate redo, redo will be generated -- append bypasses UNDO on the table data only (and hence minimizes redo, but does not bypass it). Only if it was a NOLOGGING object would the append bypass redo and then only for the table -- but not any indexes on the table (if this MV has indexes, the will always be logged regardless, they have to be) If this table is part of a refresh group, it'll be done with a DELETE (redo) plus insert (redo). But here is what you should be seeing if this is a single table (not in a refresh group) and how you can mimimize the redo generated and what'll happen if you have indexes on this: ops$tkyte@ORA920PC> select count(*) from big_table; COUNT(*) ---------- 1000000 ops$tkyte@ORA920PC> ops$tkyte@ORA920PC> drop materialized view big_table_mv; Materialized view dropped. ops$tkyte@ORA920PC> create materialized view big_table_mv as select * from big_table; Materialized view created. ops$tkyte@ORA9
