ns main err code: 12535, TNS-12535: TNS:operation timed out, ns secondary err code: 12560
Posted on 2012-04-09
I'm migrating databases from a Windows 2003 to a Windows 2008 server. And I'm having a problem when testing one of the DBLinks which work fine on the Windows 2003, but whenever I try it on the Windows 2008 I get a TNS - 12560 timeout error. I've checked both TNSNAMES and SQLNET files and they are both the same. In addition I did a TNSPING on the new machine and it failed, but when I Ping'ed the server I got a successful response I've checked log files but they report the same thing. Please help me solve this issue.
