Hi,

drop MATERIALIZED view log on afccv.tbl_voicechat;
drop MATERIALIZED VIEW SMSCHAT.TBL_VOICECHAT_NEW1 ;
CREATE MATERIALIZED VIEW SMSCHAT.TBL_VOICECHAT_NEW1

Not true in 11g:
From the docs
You cannot specify both ON COMMIT and ON DEMAND. START WITH and NEXT take precedence over ON DEMAND. Therefore, in most circumstances it is not meaningful to specify ON DEMAND when you have specified START WITH or NEXT.
In earlier versions I believe the above syntax would be invalid.

Hi Michal,
Thanks for your response. As now I created this mview and it is in use currently. So I can't drop and recreate it.
So I am using the below command for alteration.
alter MATERIALIZED VIEW "SMSCHAT"."TBL_VOICECHAT_NEW1"
REFRESH FASt START WITH sysdate+0 NEXT sysdate+10/86400
Output of the command is
SQL> alter MATERIALIZED VIEW "SMSCHAT"."TBL_VOICECHAT_NEW1" REFRESH FASt START
WITH sysdate+0 NEXT sysdate+10/86400;
Materialized view altered.
SQL>
After modification if I am checking the DDL for the meterlized view is the same as previous
SQL> l
1 SELECT dbms_metadata.get_ddl(replace(OBJECT_TYPE, ' ', '_'), OBJECT_NAME,OW
NER)
2 FROM DBA_OBJECTS
3 WHERE OBJECT_TYPE in ('MATERIALIZED VIEW')
4* AND OWNER = 'SMSCHAT'

Hi Michal/CookieMaster,
where I ran this query now then it is showing the below output.
1* select mview_name,last_refresh_date from dba_mviews
SQL> /
MVIEW_NAME LAST_REFRESH_DATE
------------------------------ --------------------
MGMT_ECM_MD_ALL_TBL_COLUMNS 20-jan-2011 11:44:40
TBL_VOICECHAT_NEW1 23-sep-2011 11:10:41
So I am confuse why this is showing now "23-sep-2011 11:10:41" because in previously it was showing "23-sep-2011 08:28:19"
Regards
Pradeep

Hi Michal,
Thanks for clearing but want to know why this is taking so much time. As I also checked something

SQL> spool off
LAST_DATE -
Date that this job last successfully executed
LAST_SEC
Same as LAST_DATE. This is when the last successful execution started.
THIS_DATE
Date that this job started executing (usually null if not executing)
THIS_SEC
Same as THIS_DATE. This is when the last successful execution started.
NEXT_DATE
Date that this job will next be executed
NEXT_SEC
Same as NEXT_DATE. The job becomes due for execution at this time.
TOTAL_TIME
Total wallclock time spent by the system on this job,in seconds
BROKEN
If Y,no attempt is being made to run this job. See dbms_jobq.broken(job).
According to NEXT_DATE this job should executed on specified time and mview should be get refreshed with in 10 min... but now there is 3:00PM and value is not getting changed.

Hi John,
Jobs is still running.
and altered the mview using the below command for increasing refreshment type.
alter MATERIALIZED VIEW "SMSCHAT"."TBL_VOICECHAT_NEW1" REFRESH FASt START WITH sysdate+0 NEXT sysdate+(10/86400*60)
But this command seems like hang state.
suggest what to do ... kill the job first ...or any thing else.

I am not able to understand why this is happening..... first few hours it is running fine after that this looks like a hang stage.

Hi Michal,
According to your reply. When the When I created this mview this takes hardly 10 min to complete. after that I checked the refeshment time till one 1-2 hour it was showing the correct time and refreshing properly.
So How the refreshment time now increased upto 5 hours....
Little bit confusing... can you please tel me something more in this.
Regards
Pradeep S

I'm sure Michel is right.
Do you know how to check the number of updates made to a table? If you do that regularly, you might find a sudden burst of activity which causes this workload. One way is to query dba_tab_modifications, to get up-to-date figures you have to execute dbms_Stats.flush_database_monitoring_info first. The view is cleared when the table is analyzed.
Applying changes to an MV can be quite slow, do you have any indexes on the container table?

So there has been a lot of DML on your source table. Can you check out the execution plans for the updates and delets on the MV container table? Perhaps your indexes aren't being used. Have you analyzed it recently?
(and by the way, if something I say is helpful, please let me know rather than just posting something without a "thank you")

Yes, but when was the MV container table analyzed, nit jsut te source table? What I'm trying to get at is whether the CBO could be choosing not to use indexes when locating rows for update or delete because of bad statistics.

Hi John,
As I checked MV Container Table has not been refreshed from the time created.
select object_name,object_type,created from dba_objects where object_name='TBL_VOICECHAT_NEW1';
OBJECT_NAME OBJECT_TYPE CREATED

TBL_VOICECHAT_NEW1 MATERIALIZED VIEW 23-SEP-011 16:44:40
TBL_VOICECHAT_NEW1 TABLE 23-SEP-011 16:37:53
select owner,table_name,last_analyzed from dba_tables
where table_name like 'TBL_VOICECHAT_NEW1';
OWNER TABLE_NAME LAST_ANALYZED
------- ------------------ -------------
SMSCHAT TBL_VOICECHAT_NEW1
Kindly check
thanks

Better run dbms_stats against it now! No promises, but the CBO will be relying on stats gathered by optimizer_dynamic_sampling, which will have been done the first time the MV was refreshed. This might slow things down. And then I think you really need to see the exec plans being used to refresh it.
I'm off now, good luck.
