Chapter 16: OperationsOperation Modesincrease, you must also decrease the number of dialog (online) work processes by the sameamount.This process is usually done to increase the number of batch sessions available to processbatch sessions at night, when most of the online users have gone home and you have manybatch jobs to run. During the day the opposite situation occurs. The number of batch workprocesses is reduced, and the number of dialog work processes is increased to accommodatethe number of online users.For example:Mode Dialog WP Batch WPDay 5 2Night 2 5There should always be a minimum of two dialog processes. Do not reduce the value belowtwo.There must be at least two batch work processes on the system. An individual instance,such as a dialog application server, could be configured without a batch work process. Butthere must be batch work processes to use somewhere on the system, or a task (such as atransport) will fail if it needs a batch work process to execute.For small clients with little batch processing at night, the additional process of configuringand maintaining operation modes may not be necessary. Not using operation modesreduces the level of administration required to maintain the system. Although onceconfigured and running, there is little maintenance required.To set up and use the operations modes:1. Define the operation mode (RZ04).2. Assign the instance definition to an operation mode (RZ04).3. Define the distribution of work processes for the operation modes (RZ04).This distribution is the mix of dialog and batch work processes.4. Assign the operation modes (SM63).Define or set the schedule of when the modes will switch and to what mode it willswitch to.16–22Release 4.6A/B
