Unable to sqlplus to remote db
sqlplus system/system_password@remote_db
The session hangs at this point. I have verified the following...
1. Remote host is included in the source host's /etc/hosts file
2. Global name matches the alias in the tnsnames.ora file on both source and remote hosts
3. I can tnsping the remote_db from both source and remote hosts
4. I can login to the remote_db on the remote host
