ERROR while system copy - import phase

[Former Member]

Hello Experts

I got below error message while performing system copy data import.

Could you please help what is the reason?

"This computer's host name is 'txxxxx01f' but a reverse lookup returned 'txxxxx01'. This will lead to problems later on when starting the
Web Application Server."

Hello Munkhzaya,

That error indicates the following:

• SWPM executed the command "hostname" and performed a DNS lookup to find the IP address associated to the hostname of the local server.
• Then, SWPM performed a reverse DNS lookup using the IP address.
  Receiving the same hostname was expected, but a different hostname was returned instead.
  Thus, the error was raised.

To fix the issue you must fix the DNS in such a way that the test works (hostname -> IP; reverse lookup of IP -> same hostname).

Regards,

Isaías

Thank you for the clarification!

I made change in /etc/hosts file entries and it went ok.

HelloMunkhzaya Baasandorj

I will add more to isaias.freitasanswer which is "nslookup hostname" and "nslookup IP_Address"

If both are not resulting same please talk to your network support team.

If you are using virtual host name better to look at SAP notes below

Thank you
