Re: Ora-8103 error

Have a look at MOS note 8103.1 - your symptoms sounds like “Expected Behaviour” - DDL happening during your SELECT like many others on this list have pointed out.

And the query does have some partition tables used but they aren't able to find any partition maintenance activities during this period. But there must be some DDL happening and thus the SELECT query is failing. And it might be that the DDL is too quick that it's not logged in ASH/AWR views. So is there any method to get hold of the DDL statement and its source ? I saw enabling DDL_LOGGING at the system level is one approach, but thinking if it's having any negative sides if it's set at system level for a long duration and if any other possible approach exists?
