wait_after_commit is a transaction serialization method that improves performance and data integrity with parallel DSI for heterogeneous replication.
In wait_after_commit, each thread waits to begin its first batch until the previous thread has completely committed. Sybase recommends that you use the wait_after_commit serialization method for databases that use multiversion concurrency control (MVCC) or optimistic concurrency control (OCC), such as an Oracle database. Otherwise, you can use wait_for_commit as the default method.
