Getting the error message "SAP system message No connect to database, session terminated" when connected from GUI.
This second time in last one week.
DB - Oracle 10
OS - Windows 2008 R2
Oracle and SAP are on the same server and in running state. Oracle listener is running and r3trans gave return code 0000, still none of us are able to connect to server. No network issue and None of the LUNS are SAN disks are altered from storage.
Dev_w0.txt, alert_chq.txt and DB status.JPG are attached for your reference.
Quick help is much appreciated.
