Hi,

Check the services whether 1 Jcontrol and 3 Jlaunches are working. if no, then better to restart you Java instance, through SMICM Txn-.

Hello Sowmya,

Could you paste the entire exception of core service security failing from the std_server0.out and defaulttrace file from server0\log ?

Hi sowmya,

I think there is a problem with sapjsf user,check whether the user is logged in your abap system (001) client and also

try restarting it using the transaction smicm if your abap system is up.
