from IJSFASIEBEL I've read that using select * to create the Materialized view can cause this error, but i've dropped the view and recreated it many times, the refresh runs fine one day and gets erred out the next day. No changes were made to the base table. Can anyone tell me what the error message means or what might be causing the issue? materialized-views ora-01555 share|improve this question edited Sep 10 '14 at 2:37 WW. 14.7k75893 asked Sep 10 '14 at 2:28 Pratheek Ponnuru 612 add a comment| 2 Answers 2 active oldest votes up vote 0 down vote The problem is that your rollback segments are not large enough for the query that is being run given the other updates happening on the database at the same time. There is a full discussion of what this means here: https://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:275215756923 Possible solutions:- Create larger rollback segment to allow more changes to occur during the refresh without running out of rollback space Creating an index on LAST_UPD to improve the speed of the query (if indeed it does) Running the refresh at a quieter time of day share|improve this answer answered Sep 10 '14 at 2:36 WW. 14.7k75893 add a comment| up vote 0 down vote Pratheek Ponnuru, Please check if any LOB are there in the table , t

ORA-12008 tips Oracle Database Tips by Burleson ora-12008: error in materialized view refresh path table or view does not exist 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: ORA-12008: error in materialized http://stackoverflow.com/questions/25756418/oracle-materialized-view-refresh-fails-with-ora-01555 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 occur while the table is being http://www.dba-oracle.com/t_ora_12800.htm 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.

ever hit an ORA-1555 refreshing a materialized view over a DBLink? See here: Errors in file /opt/oracle/db/dcim1/orabase/diag/rdbms/dcim1/DCIM1/trace/DCIM1_j000_20139.trc: ORA-12012: error on auto execute of job 81 ORA-12008: error in materialized view refresh path ORA-01555: snapshot too old: rollback segment number 16 with name "_SYSSMU16_691196082$" too small ORA-02063: preceding line from REMOTEDB ORA-06512: at "SYS.DBMS_SNAPSHOT", line 2566 ORA-06512: at "SYS.DBMS_SNAPSHOT", line 2779 ORA-06512: at "SYS.DBMS_IREFRESH", line 685 ORA-06512: at "SYS.DBMS_REFRESH", line 195 ORA-06512: at line 1 For oracle this is quite common as they have a document for all errors raisable during MV operations (note 1087507.1) and a section for specifically ORA-1555. Leave for a moment the MV aside; ORA-1555 is well know for being raisable when a session is trying to access to data no longer available in the UNDO tablespace while another session is stinll modifying data. So this error is related to Oracle read consistency mechanism. But how can be possible to hit ORA-1555 when there are absolutely no session and data manipulation on the database? I think at this point the error become interesting. And might be attributable to a bug. Oracle suggests this 3 bugs: BUG: 5964913 - ORA-1555 DBMS_REFRESH.REFRESH AFTER UPGRADING MVIEW SITE FROM 8.1.7.4.0 TO 10.2. BUG: 6086991 - MVIEW REFRESH VIA REFRESH GROUP AUTO JOB FAILING WITH 1555. BUG: 611416 - SELECT AFTER UPDATE AND COMMIT DOESN'T SHOW UPDATED COLUMNS Bugs start from Oracle 7.3.4 and status is "84 - Closed, not feasible to fix". Not feasible to fix? Oh my God I can say. What does it mean? Is it recognized as a bug but there is no way to fix or overcome it and a workaround is always the preferred solution? A workaround from version 7.3 till today?
