A Comparative Study on Oracle and IBM
... Oracle uses row-level locking as the default concurrency model and stores locking information within the actual rows themselves. By doing so, Oracle can have as many row level locks as there are rows or index entries in the database, providing unlimited data concurrency. DB2 also supports row-level ...
