How to find an Operation mode Switch

How do you find that an operation mode switch occurred? There are many ways

1) Go to sm50. If the no of dialog work processes or background work processes changes then a operation mode switch took place.

2) Go to transaction sm63. Here you can see the time when the operation mode is set. You can guess when the operation mode switch occurs.

3) Go to transaction RZ04, here you can see the list of operation modes and their time. You can guess that from here

4) Go to transaction rz03 , here you can see the current operation mode in which the server is running.


5)
Call transaction Code sm62. Then view system events. If there is an event called SAP_OPMODE_SWITCH then operation mode switch occurred at that time. If you click on activity log you can see the time and date when the event was triggered. It is time and date of operation mode switch
