Refreshing mview inside SP

I have a materialized view XYZ which i want to refresh complete by the following command in side an sp.
DBMS_MVIEW.REFRESH('XYZ','C');
Now i have located the command just before the exception block.There are certain reasons which compelled me to refresh it like this only.My sp is getting invoked from application through jdbc thin client.Now this technique is working in some database and failing in some others.I need to identify the cause.
I appreciate any suggestion towards this.

Now this technique is working in some database and failing in some others.I need to identify the cause.And what error handling, logging do you have in place to help your investigations?
Cheers, APC

Fast Refresh mview performance

Hi,
I'm actually facing with Fast Refresh Mview performace problems and i would like to know what is the possible improvments for the fast refresh procedure:
- base table is 1 500 000 000 rows partitions by day , subparttion by has (4)
- mlog partition by hash (4) with indexes on pk and snaptime
- mview partition by day subpartition by hash (4)
10 000 000 insertions / day in base table/mlog
What improvment or indexes can i add to improve fast refresh ?
Thanks for help

Hi,
Which DB version are you using?
Did you have a look at the MV refresh via Partition Change Tracking (PCT)?
http://download.oracle.com/docs/cd/B19306_01/server.102/b14223/advmv.htm#sthref575
If it's possible to use PCT, it would probably improve a lot the performance of the refresh of your MV.

Programmatically refresh components inside a specific row of an af:table

How to programmatically refresh components inside a specific row of an af:table without refreshing the whole table ?_
I have an af:table displaying a read-only view object. There is an edit button inside the table calling an af:popup, where the user can update some informations and click a submit button to validate his changes.
The action property of this button is a method in a backing been where
-     1 : A stored procedure is called to update several tables (related to my read-only VO).
-     2 : The VO is re-queried (VO. refreshQueryKeepingCurrentRow() )
-     3 : The whole table is refreshed (AdfFacesContext.getCurrentInstance().addPartialTarget(myTable) )
Is it possible to programmatically refresh some components of the current row of the table without refreshing the whole table (point 3)?
I’ve tried to play with the “partialTrigger” property of af:outputText (table:column:outputText), without success.
Thanks
Nicolas

"+do you happen to want to refresh following an action on the row? Like a link/button click?+" : NO
There is a table on my page. The user select a row and click on an edit button. This edit button call a popup where the user can modify some information (not directly on the viewObject. All fields in the popup are dummy fields bind to attributes in my backing bean) and then he click on a submit button.
The submit button action execute a method "submitInformation" in a backing been.
public String submitInformation(){
        Map<String, Object> params = new HashMap<String, Object>();
        params.put("pManNo", xManNo.getValue()); //xManNo is an attribute of the backing bean
        params.put("pDate", xPeriod.getValue()); //xPeriod is an attribute of the backing bean
        // Execute Operation
        OperationBinding oper = ADFUtils.findOperation("serviceSubmitInfo");
        oper.getParamsMap().putAll(params);
        String results = (String)oper.execute();
        // Close Popup & Refresh Row if OK
        if(!StringUtils.isStringEmpty(results) && results.equals("TRUE")){
             closePopup("pt1:popAbs");
             refreshMyCol();
}The serviceSubmitInfo method is defined in my serviceImpl
    public String serviceSubmitInfo (String pManNo, String pPeriod, ......){
         String results =
            callStoredFunction("? :=myDatabaseFunction(?, ?, ?, ?)",
                               new Object[] { pManNo, pPeriod, ...... });
          // Commit
          getDBTransaction().commit();
          // Refresh VO (re-query & set currentRow)
          getMyVO().refreshQueryKeepingCurrentRow();
          return results; // TRUE if ok
    }I want the " refreshMyCol()" method to refresh only the current row and not the whole table...

Refreshing mview is hanging after a database level gather stats

hi guys,
can you please help me identify the root cause of this issue.
the scenario is this:
1. we have a scheduled unix job that will refresh an mview everyday, from tuesday to saturdays.
2. database maintenance being done during weekends (sundays), gathering stats at a database level.
3. the refresh mview unix job apparently is hanging every tuesdays.
4. our workaround is to kill the job, request for a schema gather stats, then re-run the job. and voila, refresh mview will be successful then.
5. and the rest of the weekdays until saturdays, refresh mview is having no problems.
we already identified during testing that the scenario where the refresh mview is failing is when after we are gathering stats in a database level.
during gather stats in a schema level, refresh mview is successful.
can you please help me understand why we are failing refreshing mview after we gather stats in the database level??
we are using oracle 9i
the creation of the mview goes something like below:
create materialized view hanging_mview
build deferred
refresh on demand
query rewrite disabled
appreciate all your help.
thanks a lot in advance.

You know Tuesday's MV refresh "hangs".
You don't know why it does not complete.
You desire solution so that it does complete.
You don't really know what is is doing on Tuesdays, but hope automagical solution will be offered here.
The ONLY way I know how to possibly get some clues is SQL_TRACE.
Only after knowing where time is being spent will you have a chance to take corrective action.
The ball is in your court.
Enjoy your mystery!

Fast Refreshable MVIEW

Trying to create a fast refresh materialized view based on a simple join of two tables over a database link oracle gives a 'COMPLEX QUERY' error (ORA-12015).
Logging on the origin tables should be ok as creating the MVIEW based on the same select but in the database where the origin tables are poses no problem. The logging tables are created based on primary key and include rowid.
The select on which the MVIEW should be created is someting like:
select
tab1.rowidn id1,
tab2.rowidn id2,
tab1.key_idn key1,
tab2.key_idn key2
from table1@other_db tabl,table2@other_db tab2
where tab1.key_idn = tab2.key_idn)
Does this mean it is impossible to create a fast refresh materialized view over a database link when a join condition is involved?

Replace the ANSI Joins with Conventional Joins.
Change this :
SELECT * FROM V_FIRST VF
LEFT JOIN R4
ON VF.ID=R4.ID
LEFT JOIN R5
ON VF.ID=R5.IDto this :
SELECT VF.* FROM V_FIRST VF, R4, R5
WHERE VF.ID=R4.ID
AND VF.ID=R5.IDHemant K Chitale

hi sir ,
thaks for u'r suggession.Its working fine but the
properties of the previous tree were not working
after setModel() property .like action at leaf node
is not working,I'm sorry but I don't understand. I think you are saying that the problem is solved but I can read it to mean that you still have a problem.
If you still have a problem then please post some code (using the [code] tags of course).

Fast refreshable mviews vs. cdc

im currently working on a new data warehouse environment. i need to create an ods schema for each of the operational systems in my warehouse.
i've looked at two of 10gR2 prefered technologies for this task:
fast refreshable materialized view and change data capture.
i would to know what is the difference between this two approaches.
in my understanding, there both cause a performance overhead and require some amount of additional work on each dml operations. in addition , there both work on the method of capturing changes from a table and applying them on a target database.
the only difference i could think of is that cdc capture changes from the redo log so that commit time on the operational system wont be affected (as much as it would when logging a dml operation in a mview log).

dba_snapshot_refresh_times or dba_mview_refresh_times would help.
select job, last_date last_refresh, next_date next_refresh, total_time,what from dba_jobs where what like '%dbms_refresh%'
This will work only if the refresh is scheduled to run through job queue.

Error when try to Fast Refresh Mview ......

Guys d u have an idea .....
why when I running job that fast refresh an mview.
I alwayas got error :
ORA-12008: error in materialized view refresh path
ORA-01555: snapshot too old: rollback segment number 2268 with name
"_SYSSMU2268$" too small
undo_management set to AUTO.
undo tablespace has enough space.
I have mview log on master database.
regards,
indrajati

damorgan's request for more information is completele relevant.
However, "Snapshot to old" is often due to insufficient rollback/undo space. What happens (grossly simplified) is that when re-reading stored data the database finds it has been overwritten and raises the error. The suggested fix is usually to increase rollback/undo space.

Refresh Mviews

hi all,
I have few Materialized views that are dependent on one another..
ex: mv1, mv2, mv3..
I wrote code that will submit jobs to refresh all 3 views at the same time...
but it should be in the order mv1, mv2, mv3..
well, i can loop through it in that order...
then what's the problem?
which table should i look up to make sure that the mview has refreshed successfully..
i am assuming it is not the "all_scheduler_jobs" coz it just says that the job is submitted successfully...
correct me if i am wrong..
and could any one help me out of this..
thank you

I think i need to rephrase my question..
how to refresh nested materialized views...
and i think i found the answer in my book....
in DBMS_MVIEW.REFRESH procedure..
need to set the nested parameter to TRUE...
thanks for looking at my question.... and answer too..
please let me know if i am wrong...
thank you

How much time My FAST refreshable MVIEWS taken to refresh in last refresh?

How to find the DURATION of last FAST refresh of MVIEWS?
Refresh duration will vary depends on data change on base table. I would like to find the duration of last refresh

dba_snapshot_refresh_times or dba_mview_refresh_times would help.
select job, last_date last_refresh, next_date next_refresh, total_time,what from dba_jobs where what like '%dbms_refresh%'
This will work only if the refresh is scheduled to run through job queue.

You would be able to answer yourself your question, if you
a) read the restrictions for fast refresheable materialized view at
http://download.oracle.com/docs/cd/B19306_01/server.102/b14223/basicmv.htm#sthref537
b) make you familiar with the packaged procedure dbms_mview.explain_mview

I think we can create a fast refreshable Mat view which has UNION ALL operator... I don't know about remote tables.
How to achieve this... with out splitting the Mat view ?. Is there any way..?
Appreciate your help.

Any help is appreciated

Hi.
This is because you did not created a snapshot, but a materialized view.
I suggest you to try with the dbms_refresh package to refresh your materialized view instead of using dbms_snapshot, please let me know the results
