wait_for_start

wait_for_start specifies that a transaction can start as soon as the transaction scheduled to commit immediately before it has started. See Figure 4-5.

Sybase recommends that you do not concurrently set dsi_serialization_method to wait_for_start and dsi_commit_control to off.

Figure 4-5: Thread timing with wait_for_start serialization method
