In order to install Oracle Enterprise Manager 12c, the hosts
file needs to be correctly set.
Before you start, ensure that the server is connected to the network and an SSH or a telnet client is available. Also, make sure you have access to the Unix server as a root user or as a privileged user having root access.
Open the vi editor in a PuTTY session and include the following line in the /etc/hosts
file. The details of the IP address and server name need to be specified, as follows:
999.999.99.999 servername.domain_name.com servername
The hosts
file is required for the installation to complete successfully. The location of the hosts
file will vary depending on the operating system being used. The previous file location is valid for Oracle Enterprise Linux.
