In Oracle 10+ versions, can update and delete on the same table cause deadlocks even if they are operating on different rows of same table concurrently?
The table has primary key made-up of two columns, and do not have any FK associated/refereed with any other table. And there is no parent/child relation with other table
What I believe is, it will not create a deadlock, but I'm facing a issue in my application.
adding the oracle trace :
The following deadlock is not an ORACLE error. It is a deadlock due to user error in the design of an application or from issuing incorrect ad-hoc SQL. The following information may aid in determining the deadlock:
