Checking the Operation Mode with the Control Panel 

Use

The main function of the control panel is starting and stopping instances. However, you can also use it to check whether instances were started correctly and whether they are running in the correct operation mode; that is, whether automatic operation mode switching is possible.

Procedure

How to gain an overview of operation modes and instances

       1.      Start the Control Panel by choosing CCMS ® Control/Monitoring ® Control-Panel.

The Control Panel displays a list of the host systems and instances in your SAP R/3 System. The list contains:

Instance names

Status

Services that are running on your application server

Active operation mode

       2.      Select a server.

How to find out the cause of the non-standard operation mode:

       3.      Choose Monitoring ® Status Details.

A dialog window appears that shows details for the server.

The most common cause for an operation mode switch failing is inconsistencies in the total number of work processes or in the profiles.

Once you have solved the problem, switch the operation mode manually from the Control Panel.
