Checking TCP/IP configuration
Web technologies rely heavily on TCP/IP. Before you install the Zend Core product, ensure
that TCP/IP is appropriately configured.
In particular, check the following configuration settings:
Ensure that a host name is defined for the system. Run the Configure TCP/IP (CFGTCP)
command and select option 12 (Change TCP/IP domain information) to display this
setting. Make sure that a value is listed in the Host name field.
Make sure that the loopback entry (which represents “localhost” or 127.0.0.1) is
configured in the TCP/IP host table. Run the Configure TCP/IP (CFGTCP) command and
select option 10 (Work with TCP/IP host table entries) to display the host table. Ensure that
an entry for the IP address 127.0.0.1 exists and is mapped to host names LOOPBACK
and LOCALHOST.
Also on this display, check that the IP address for the i5 system is mapped to its host name
(such as SYSTEMA) and fully qualified host name (such as
SYSTEMA.MYCOMPANY.COM). You should be able to successfully ping both the
loopback address and the fully qualified host name of your system from i5/OS, and the
fully qualified host name from any browser that will be used to access PHP scripts. |
