Beginning in version 4.1.3, you can configure table-level timestamp for CMP entity beans that use OCC. EAServer maintains the table-level timestamp as a single integer counter, incrementing the count for every update, insert, or delete in the main table. The conventional model for optimistic concurrency uses row-level timestamps. For more information, see “Concurrency control options” in Chapter 4, “EJB CMP Tuning,” in the EAServer Performance and Tuning Guide.
