Hello Babu,

I faced the problem in refreshing the two materialized view. I am trying with 'complete refresh' but it hanged. If i tried to drop the materialized view then also it hanged and not able to drop the materialized views.

I am having 6 MV's and rest 4 are refreshing without any problem.

Can you please help me to solve the issue.

Thanks,
Harsh

Hi,

Sorry for delay response.

Yes I agree it takes some time but please reply me below details.

1/ Why your not going fast/force refresh?

2. Connect Sys user.

Show parameter job

show parameter query

show parameter opt 


3/

Quote:
EXEC DBMS_MVIEW.REFRESH('PART_TRACK_FRAME_EX', 'A', '', TRUE, FALSE, 0,0,0, FALSE);


a/ I think by default atomic_refresh is TRUE. May i know any specific reason why your using FALSE??

b/ Did you discussed with oracle support (metalink) to change automic_refresh parameter??

Thank you in advance.

Babu
