Assigning an Instance Definition Manually 
Use
You can assign an instance definition to an operation mode manually. This is useful if you cannot copy the actual status because the application server is not yet running.
Procedure
The system displays the CCMS: Maintain Instance Data dialog box.

Host Name |
Enter the name of the host running the instance. |
SAP system number |
Enter the instance number. |
Start profile: Profile name |
The name of the start profile from Profiles to start the instance with.Choose the input help to display a list of available start profiles. You can choose a profile from the list. |
Instance profile: Profile name |
The name of the instance profile from Profiles to run the instance with.Choose the input help to display a list of available instance profiles. You can choose a profile from the list. |

Either specify the start profile and the instance profile together from profile maintenance or do not use a profile from profile maintenance.
All data is then generated using the profile values and the R/3 default naming conventions.
The work process distribution at system start is also set from the instance profile data.

UNIX systems only: So that you can start and stop servers from the
Control Panel or the System Monitor, you must enable a remote logon on the target UNIX server. See Prerequisites for Starting Remote Instances.When using profiles, your configuration is checked automatically when you save. You are notified of any inconsistencies.
In the field Operation mode, enter the name of the operation mode or select an operation mode from the list of possible entries. To set the same work process distribution for all operation modes, enter * .
The system proposes the current work process distribution in the instance profile. However you can change the work process distribution (see Setting the Work Process Distribution).
To assign the work process distribution to further operation modes, select Yes when the system prompts you. Choose No if you do not want to assign the work process distribution to further operation modes.
From the list of productive instances, you can now create or maintain further instances.
All the instance definitions for productive operation modes are then saved in the database.
