Hello everyone, I was trying to perform RMAN backup of an 8.0.5 database using OEM 2.2 (8.1.7). I'm not sure if there is something I should do to correct this error. RMAN backup
locally works perfectly. There is nothing wrong with TNSNAMES. I've tried to log on to my test database remotely and it was okay. Any idea?

RMAN-00569: ================error message stack follows================
