Oracle doesn't have an equivalent to timestamp. It is built to support pessimistic locking. A possible solution would be to carry an extra column in each table, which would store a unique number, possibly from a sequence, which would be updated every time a database change was made. I don't recommend using a date/time column because Oracle dates only store seconds, which is probably not granular enough for concurrency checking.

Hope this helps,
