Switching Operation Modes Using Start
and Instance Profiles
Prerequisites
To switch from one operation mode to another in the SAP system, all application server instance definitions must be included in the operation mode definition.
Each operation mode should contain configuration specifications for each affected application instance. That is, how many work processes and which services (such as dialog, background processing, and spool) each application instance will provide.
Process Flow
You can get this information from the relevant instance profile, or from within the operation modes tool set. Ensure that you have a corresponding start profile so that any instance can be started from within the system.
When you switch operation modes, the new instance settings should be based on the existing profile definitions in this operating system. That is, the number of work processes and the important directory path names must be consistent.
We strongly advise you to follow the above recommendations. The advantages of this procedure are:
· The profiles and operation mode data are always consistent.
· You can change profile data (for example, the number of work processes) using the profile maintenance tool, and the corresponding operation modes can then be adjusted automatically.
· You no longer have to work with the operating system profile files.
· When all servers are assigned profiles from the profile maintenance tool, the whole system is checked thoroughly for any consistencies.
