I don't understand what mean these errors and why i got them? Someone can help me please ? Thanks regards, and we said... you have set your undo retention period too short - this is a classic ora-1555 (search asktom for that, hundreds of articles on ora-1555) increase your undo retention to be longer than your longest running query (or refresh in this case) make sure you have sufficient undo ora-12008 ora-00942 tablespace configured as well.

But why this error occurs during materialized view refresh(long running)? 2.i asked the above question, because, i have set the undo_retention to 23000 and undo tablespace size to 7gb as per the guidelines in the below link, but i still get this error(snapshot too old error) : http://www.akadia.com/services/ora_optimize_undo.html the below is the exact error message, i am getting BEGIN DBMS_MVIEW.REFRESH('test_info_mv2','C'); END; * ERROR at line 1: ORA-12008: error in materialized view refresh path ORA-01555: snapshot too old: rollback segment number 2 with name "_SYSSMU2$" too small ORA-02063: preceding line from OPRD.DSTB.NET ORA-06512:

ORA-12008 tips Oracle Database ora-12008: error in materialized view refresh path ora-01722: invalid number Tips by Burleson Consulting May 26, 2015 Question: I am using dbms_redefinition to redefine a table and I am getting an ORA-12008 and an ORA-01555 error: https://asktom.oracle.com/pls/apex/f?p=100:11:0::::P11_QUESTION_ID:409663900346414175 ORA-12008: error in materialized view refresh pathORA-01555: snapshot too old: rollback segment number with name "" too small ORA-22924: snapshot too old ORA-06512: at "SYS.DBMS_REDEFINITION", line 52 ORA-06512: at "SYS.DBMS_REDEFINITION", line 1646 Why do I see a ORA-12800 error? Answer:The dbms_redefinition uses a materialized view during the reorganization to manage the updates that http://www.dba-oracle.com/t_ora_12800.htm occur while the table is being copied and re-named. In your case, the ORA-12008 error is a phantom error message, with your true error being the ORA-01555. The oerr utility show this on the ORA-12008 error: ORA-12008: error in materialized view refresh path Cause: Table SNAP$_ reads rows from the view MVIEW$_, which is a view on the master table (the master may be at a remote site). Any error in this path will cause this error at refresh time. For fast refreshes, the table .MLOG$_ is also referenced.Action: Examine the other messages on the stack to find the problem. See if the objects SNAP$_, MVIEW$_, .@, .MLOG$_@ still exist.

This error can be seen when operating on a largevolume of data if hash group by aggregation is used. It is possible for hash group-bys to over allocate memory beyond the limit imposed by the auto-memory manager because of this bug. You can do one of the following and then rerun the mview refresh to work around the problem. a.)sql>alter session set "_gby_hash_aggregation_enabled"=false; b.) use theno_use_hash_aggregation hint.
