Committed transactions disappearing from table

Asked by aljubicic in Oracle 10.x

Tags: Oracle, Oracle, 10g

Currently one our applications has a problem when inserting and deleting records from a specific oracle table.

The application will insert records or delete records from a few tables and this will do it within a whole transaction. So if any part of the transaction fails it will rollback the entire transaction or commit it, if everything works. Now the problem is once it commits the whole transaction every so often a record will be missing from one of these tables and it will always occur on the same table. It doesn't occur every time but it does occur. Now our application has a batch process which has a high volume of activity at say 6am which runs through say thousands of transactions. Now with a few of these committed transactions we would go in and find that an insert statement will be missing(no record exists) eventhough when I look through logminer and oracles auditing that the transaction and the insert statement actually committed. I also checked to see if any deletes occured on this record and there wasn't any. Pretty much the record disappears. I have even placed triggers to write the information out to a table to check on commits if the insert statements ran and if any deletes occured on this record and from all my findings the record should exist but doesn't.

I also have had some Oracle experts have a look at this issue to see if they could find out anything and they were as stumped as I was.

So I was just wondering whether anyone has come across such a bug or if they have any ideas in what I could do to investigate it further? Any ideas would be great.
