Hello,

I got this error message in my replication environment.

ORA-12012: error on auto execute of job 2182370
ORA-12008: error in materialized view refresh path
ORA-00001: unique constraint (TE.S_TE_MTH_DBASE_SALES_INFO_A_U1) violated
ORA-06512: at "SYS.DBMS_SNAPSHOT", line 189

Materialized view and Base table having only one unique index. There are no referable constraints in my base table. Because source table not refer any other tables.

Even; materialized view log created using rowid because there are no primary key constraints in my base table.

When I manually refresh materialized view I got the below error message

ORA-00001: unique constraint (TE.S_TE_MTH_DBASE_SALES_INFO_A_U1) violated


How it's possible? Because there is parent/child relationship in my source table and there is no way to enter duplicate records it's unique index.

Please let me know why occurs this error?

Babu

Search the root of the error then you'll get the reason why it happens.

Yes there is a root error as you have duplicates they don't appear by miracle.
Search why you have duplicates.
Search what are the duplicates.

>>Search why you have duplicates.
>>Search what are the duplicates.


Yes; you’re correct Mr.Michel; once occur error from my database; immediately i checked duplicate records in my database

There is no duplicate records; Even my table/materialized view having unique index so; there is no way to enter duplicate records.

I'm correct? Advice me

Thanks
Babu

You can't enter duplicates but you can have duplicates during replication if the values already exist in mv.
Check.

And so the error you got.
The error comes that when you refresh you try to violate this constraint, search why, which rows try to violate this constraint.
