Setting the ORACLE_HOSTNAME Environment Variable
-----------------------------
Use the following procedure to set the ORACLE_HOSTNAME environment variable.
For example, if the fully qualified host name is somehost.us.acme.com, then enter
one of the following commands:
Bourne, Bash, or Korn shell:
    $ ORACLE_HOSTNAME=somehost.us.acme.com
    $ export ORACLE_HOSTNAME
C shell:
    % setenv ORACLE_HOSTNAME somehost.us.acme.com
