ORA-12034: materialized view log on table younger than last refresh
I am getting this error while creating the materialized view.
This error seems to be refresh error.
but when i have a mat view log already and running script to create the materialized view how can that happen?
34MCA2K2, Google lover?
I confess perhaps I gave a little info.
View log was created before MV.
It was the first initial load.
No refresh failed.
No DDL.
No purge log.
Not warehouse.
There is no such behavior for MVs on another sites.
P.S. I ask help someone who knows what's wrong or who faced with it or can me follow by usefull link.
P.P.S. It's a pity that there is no button "Useless answer"

Reg ora-12034 materialized view log on younger than last refresh
Hi,
when i update my base table materialized view log shows the updated rows
but when i refresh materialized view it wont show updated rows in materialized view and also there is no rows in materialzed log
it shows error ora-12034: materialized view log on younger than last refresh
cheers,FIX
A complete refresh is required before the next fast refresh.
Please run the process "Refresh Materialized Views" -
Error ora 12034 view log younger than last refresh
I have a materialized view and a log that produces the error ora 12034
I have tried to drop and recreate but there is no change in error what oracle says.
Then I tried to refresh complete
EXECUTE DBMS_MVIEW.REFRESH('VM_IS_CALC','C')
But also there is no change in the shown error.
I can not see the error to synchronize the Log with the view
especially I will prevent that this error came in future.
Has anyone help? Thank you

Performance consequences to adding materialized view logs to tables?
I am writing a very complex query for a client of our transactional database system and this will require the creation of a materialized viewbecause all attempts at tuning to make performance acceptable have failed.
I want to enable fast refresh of the MVIEW but I am confused regarding the consequences of the addition of adding materialized view logs to the base tables.
Some of the tables are large and involved in alot of transactions and I am wondering if the performance of INSERT/UPDATES will be seriously affected by the presence of an mview log.
This may be a simple question to answer but I was unable to find a clear cut answer in the literature.
Thanks for any answers!!

Biotechnology Data Management ConsultantLast time i looked into this there were three cases to consider
If you're doing conventional row-by-row DML then the impact is just one insert into a heap table per row modified.
If you are modifying a high number of rows using bulk-binds then the overhead is very severe because modifying 1,000 rows on the base table causes 1,000 non-bulk bound inserts into the log table.
Direct path inserts have extremely low overhead because the MV log is not touched. Instead, the range of new rowids added is logged in ALL_SUMDELTA

ORA-12096: error in materialized view log
Hi All,
I had created a fast refresh materialized view. Log was also created.
Now i dropped the mv and the logs.
But now every time i update or insert into this customer table i get error message.
ORA-12096: error in materialized view log on Customer
ORA-00942: table or view does not exist
There are entries in the DBA_MVIEW_LOGS for customer table.
Please suggest.Hi,
What database version are you on?
And do you have access to Metalink/My Oracle Support?
Found this, by the way:
ORA-12096: error in materialized view log on <table>
If problems occur when you try to access a log file for a materialized view, the system issues an ORA-12096 error message which is followed by the actual error. If the ORA-12096 error message is accompanied by an ORA-00942 message, the problem may be due to an online reorganization that was only partially undone. In this case, you can drop the log file for the materialized view manually (after you have verified that it is no longer required):
DROP MATERIALIZED VIEW LOG ON <table>;

Truncate table and materialized view log
I user oracle 10 R2
I have a table and on that table a materialized view log.
I execute in a pl/sql procedure:
1) execute immediate('drop materialized view log on tab1');
then:
2) execute immediate('truncate table tab1');
3) Now I insert a lot of records in tab1
4) execute immediate('create materialized view log on tab1 WITH rowid INCLUDING NEW VALUES');
When I create the materialized view log I recieved this message:
ora32321: refresh fast on tab2 unsupported after detail table truncate
Why?Refresh fast after truncate operation on container table is not supported, regardless the container table is or is not partitioned.
Perform a refresh complete.
ORA-32321 :
Cause: A detail table has been truncated and no materialized view
supports fast refersh after a detail table has been truncated
Action: Use REFRESH COMPLETE. Note: you can determine why your
materialized view does not support fast refresh after TRUNCATE
using the DBMS_MVIEW.EXPLAIN_MV() API. -
Can't update master table when creating a materialized view log.
Hi all,
I am facing a very strange issue when trying to update a table on which I have created a materialized view log (to enable downstream fast refresh of MV's). The database I am working on is 10.2.0.4. Here is my issue:
1. I can successfully update (via merge) a dimension table, call it TABLEA, with 100k updates. However when I create a materialized view log on TABLEA the merge statement hangs (I killed the query after leaving it to run for 8 hrs!). TABLEA has 11m records and has a number of indexes (bitmaps and btree) and constraints on it.
2. I then create a copy of TABLEA, call it TABLEB and re-created all the indexes and constraints that exist on TABLEA. I created a materialzied view log on TABLEB and ran the same update....the merge completed in under 5min!
The only difference between TABLEA and TABLEB is that the dimension TABLEA is referenced by a number of FACT tables (by FKs on the FACTS) however this surely should not cause a problem. I don't understand why the merge on TABLEA is not completing...even though it works fine on its copy TABLEB? I have tried rebuilding the indexes on TABLEA but this did not work.
Any help or ideas on this would be most appreciated.
Kind Regards
Mitesh
email: [email protected]Thats what I thought, the MVL will only read data that has changed since it was created and wont have the option to load in all the data as though it was made before the table was created.
From what I have read, the MVL is quicker than a Trigger and I have some free code that prooved to work from a MVL using it as a reference to know what records to update. There is not that much to a MVL, a record ID and type of update, New, Update or Delete.
I think what I will have to do is work on a the same principle for the MVL but use a Trigger as this way we can do a full reload if required at any point.
Many thanks for your help. -

NOthing relevant is coming up over metalink for the erorr. Some non-required results are coming but I dnt think that they are helpful. The most nearest to your error is this thread over google,

Will Materialized view log reduces the performance of DML statements on the master table
Hi all,
I need to refresh a on demand fast refresh Materialized view in Oracle 11GR2. For this purpose I created a Materialized view log on the table (Non partitioned) in which records will be inserted @ rate of 5000/day as follows.
CREATE MATERIALIZED VIEW LOG ON NOTES NOLOGGING WITH PRIMARY KEY INCLUDING NEW VALUES;
This table already has 20L records and adding this Mview log will reduce the DML performance on the table ?
Please guide me on this.Having the base table maintain a materialised view log will have an impact on the speed of DML statements - they are doing extra work, which will take extra time. A more sensible question would be to ask whether it will have a significant impact, to which the answer is almost certainly "no".
5000 records inserted a day is nothing. Adding a view log to the heap really shouldn't cause any trouble at all - but ultimately only your own testing can establish that. -
! Materialized View log VS Trigger to trace table changes !
Hi All
I have to trace changes on couple tables and only those changes then send to other system.
What do you think is better solution to create a Status table and update it via trigger.
I saw that MV log can be used for such purpose, but I am not able to create a MV logging on more than one table.
Or is there any other more effective way to trace changes on table?
Thanks a lot
MartinIt sounds like you should be looking at something like Change Data Capture (CDC). You could also create materialized view logs on each table where you wanted to track changes, create appropriate materialized views on the remote database, and consume the data there. It really depends on what exactly you want to do with the changes you're tracking.

Materialized View Log table with sequence
I have a materialized view log in Database A..a very simple one...similar to "create materialized view log on t WITH PRIMARY KEY"...The primary key is a composite key of 2 columns...Description of the mlog table looks like this...
desc mlog$_t
emp_ctr NUMBER
emp_date DATE
SNAPTIME$$ DATE
DMLTYPE$$ VARCHAR2(1)
OLD_NEW$$ VARCHAR2(1)
CHANGE_VECTOR$$ RAW(255)
The Materialized view is in database B...again a simple one...no aggregation...This gets refreshed on demand manually evey week. The records that get accumulated in the MLOG every week is ~ 300K..The manual refresh used to finish in about 20mins but since last week it is running for ever. Upon reviewing the contents of MLOG I noticed that it contained a mixture of inserts and updates. I'm not sure if the MLOG contanied only inserts in the past when the MV used to refresh very quickly...Based on the documentation, Oracle recommends creating MLOGS with "sequence" whenever inserts/updates/deleted are expected. I'm planning to drop and recreate the MLOG with sequence with the hope that this would fix the slow refresh issue...Appreciate if you could let me know your thoughs...
I'm also planning to trace the session to get some wait event statistics to find out the reason for the slow refresh...There are a few reasons why refreshes slow down over time.
1. Is the log table being cleared out after a refresh? If not, you may have another mview (maybe even one that doesn't exist any more) registered against this log. When this happens, the log table never stops growing.
2. How big is the segment occupied by the table? If it has grown very large at some time in the past (e.g., because refresh was delayed), then when the refresh does a FTS on the log it will scan the whole segment - even if only a few rows are present.
3. It may help to add an index to the PK columns, and another to SNAPTIME$$. Without them, the refresh will FTS the log. For a big segment, that can take a long time.

How to CREATE MATERIALIZED VIEW LOG (MV fast refresh) with some JOINS
Hi @ all,
i'm trying to create a MATERIALIZED VIEW LOG for a fast refresh of a MATERIALIZED VIEW.
It works fine with a simple Request in the MATERIALIZED VIEW:
CREATE MATERIALIZED VIEW MV_ZOTD43_P
TABLESPACE GDII
BUILD IMMEDIATE
REFRESH FORCE AS
SELECT * FROM ZOTD43_P;
COMMIT;
CREATE MATERIALIZED VIEW LOG ON ZOTD43_P
TABLESPACE "GDII"
WITH PRIMARY KEY, ROWID, SEQUENCE INCLUDING NEW VALUES;
call DBMS_MVIEW.REFRESH('MV_ZOTD43_P', 'f');
But when I use a complex SQL-Request with some JOINS (one of the Table with spatial Data) in the MATERIALIZED VIEW, I get an error:
CREATE MATERIALIZED VIEW MV_TEST
TABLESPACE GDII
BUILD IMMEDIATE
REFRESH FORCE AS
SELECT lptd04_p.sst_nr AS sst_nr,
lptd03_p.aaaa AS aaaa,
lptd04_geom.geom as geom
FROM lptd04_p lptd04_p
JOIN lptd01_p lptd01_p ON lptd01_p.cre_nr = lptd04_p.sst_nr
JOIN lptd04_geom ON lptd04_geom.sst_nr = lptd04_p.sst_nr
JOIN lptd03_p lptd03_p ON lptd03_p.lief_nr = lptd04_p.lief_nr;
COMMIT;
CREATE MATERIALIZED VIEW LOG ON LPTD04_P
TABLESPACE "GDII"
WITH PRIMARY KEY, ROWID, SEQUENCE INCLUDING NEW VALUES;
call DBMS_MVIEW.REFRESH('MV_TEST', 'f');
Error report:
SQL Error: ORA-12004: REFRESH FAST kann für Materialized View "GDI"."MV_GDI_SST_STAMM" nicht benutzt werden

*Cause: The materialized view log does not exist or cannot be used. PCT
refresh is also not enabled on the materialized view
*Action: Use just REFRESH, which will reinstantiate the entire table.
If a materialized view log exists and the form of the materialized
view allows the use of a materialized view log or PCT refresh is
possible after a given set of changes, REFRESH FAST will
be available starting the next time the materialized view is
refreshed.
Am I doing something wrong or is it not possible CREATE MATERIALIZED VIEW LOG when the MATERIALIZED VIEW got some JOINS?

Creation of Materialized view and Materialized view log.
I wanted to create materialized view with 'REFRESH FAST ON COMMIT' option.
1) Table1 --it is partitioned range + list -- Added primary key
2) view1 -- having primary keys on view's base table
Steps:
1) create materialized view log on Table1 ; -- default primary key
2) create materialized view log on view1. --- It is giving below error.
ORA-00942: table or view does not exist
i wanted to create Materialized view like below
create materialized view
REFRESH fast ON commit
as
select ...
... from table1
where c1 in (select c1 from view1 where ... );
Question:
1) As i am getting above error while creating MV log on view. Can we create MV log on view or we have to create MV log on view base table?
2) To create MV with ''REFRESH FAST ON COMMIT' option , do we need to have primary key on master tables?
Any pointers on this will really helpful.
Thanks
PrasadAlso created MV LOG on 3 tables and tried with joins ..
create materialized view
REFRESH fast ON commit
as
select ...
... from table1 , tab2 t2,tab3 t3
where ....
and ...
Get same error ORA-12052: cannot fast refresh materialized view AVSYS.EVENT_LOG_MV
2052. 00000 - "cannot fast refresh materialized view %s.%s"
*Cause: Either ROWIDs of certain tables were missing in the definition or
the inner table of an outer join did not have UNIQUE constraints on
join columns.
*Action: Specify the FORCE or COMPLETE option. If this error is got
during creation, the materialized view definition may have be
changed. Refer to the documentation on materialized views.
