Creating an Instance Definition for All
Servers
You can generate the current instance definition for all the active servers. This procedure is helpful if you want to generate all instance descriptions for the first time.
...
1. Choose CCMS → Configuration → Operation Modes/Instances → Instances/Operation modes, or call transaction RZ04.
2. The screen CCMS: Maintain Operation Modes and Instances appears. Choose Settings → Based on current status → New instances → Generate. The system now queries the current status of every active application server, and an instance definition is created.
For every configured operation mode, the system creates a work process distribution in accordance with the distribution of the respective instance profile.
3. Save the new instance.
4. Define the work process distribution for switching operation modes.

If you want to start and stop servers from the control panel, you should maintain the instance startup user.

5. When you have finished defining the work process distribution, you can perform a consistency check.
It only makes sense to do this if you are maintaining profiles using the CCMS profile maintenance tool.
6. Save your changes. All the instance definitions for productive operation modes are then saved in the database.
