Hi Yasir,
Follow the steps :
1. stop the java instance.
2. Rename the Server0 file to server0_old (also rename the server<x> folders if you have more server node.
3. Restart the java instance
On restarting the java instance , it will create a new server<x> folder and this time it will create the binaries from the database.
Then resume the SUM tool.
Also follow the sap note
