It can be difficult to determine the optimal value for the multiprogramming level. For example, if a database application uses Java stored procedures, or if intra-query parallelism is enabled, then the additional server tasks that are created to process these requests may exceed the current multiprogramming level, and execution of these tasks must wait until another request completes. In these cases, raising the multiprogramming level may be appropriate. You can adjust the multiprogramming level of a network database server at any time. However, for personal database servers you cannot change the multiprogramming level after the server has started.
