Hello ,
I saw this note and applied it but no hope .. this note contains uid=SAPSR3 , however in my case it's strange to see UID=SABAP
have you see this case before ?
N.B : i had changed something in dbco last time login to system and application was running but in db13 there's no connection while pushing button ( test connection )
also , due to some configuration i changed SYB<SID> password and <SID>ADM from OS level .
Regards ,
Yasser
