Is the remote machine up? Is the listener running? Is there a network
problem?New Firewall configuration? Can you ping the remote machine?
Can you telnet the listener (telnet remotemashine 1521 if use the
default port) Has the ip adress changed?
Have you tried to restart the listener. What is the output of lsnrctl
status
There may be hundreds of reasons. Your question is just too general too
give a concret answer.
