TNS-12537: TNS:connection closed
Hello,
I just upgraded a db from 10g to 11g. Everything works fine. I can connect to my new 11g from putty and third parties like toad and sql developer. I can ping service name, IP, sever name just fine. Listener is running but for some reason when i tail my alert log file, there is this error
TNS-12537: TNS:connection closed
ns secondary err code: 12560
nt main err code: 507
TNS-00507: Connection closed
nt secondary err code: 0
nt OS err code: 0
Any help resolving this? I don't know what i am missing...
Thanks
