1. From the R/3 main menu, choose Tools ® CCMS, Configuration ® OP modes/instances.

Alternatively, call Transaction RZ04.

The system displays a list of productive instances.



If you have not yet defined any operation modes, the test operation mode DUMMY will be displayed. This operation mode is configured automatically so that system functions such as the Control Panel and background job scheduling can be used.

If a DUMMY operation mode is already available, it is updated whenever a server is booted. In this way, it is adjusted to the changed system conditions.

The operation mode DUMMY cannot be used for operation mode switching.

2. Create a new operation mode (that can be switched automatically)

To do this, choose Operation mode ® Create.

3. Enter data in the following fields:

Operation mode:	Enter a name for the operation mode, for example DAY_OPERATION , and a short description. You can enter any name for the operation mode, but it is better to choose a name that is meaningful and that makes the task of the operation mode clear.
Short description	Type a short description of the operation mode, for example, "Day operation with 6 dialog processes."
Productive operation mode	Productive operation modes are intended for standard R/3 system operation. Only productive operation modes can be set up in such a way that they can be switched automatically. For this reason you should normally define productive operation modes.
Test operation mode	A test operation mode can only be switched manually. Set up a test operation mode if, for example, you want to test the instances in a particular configuration which cannot be used in the productive operation mode.

4. Save the data.

To do this, choose Operation mode ® Save.

5. Repeat this procedure for all other operation modes that you require.
