Need to change Host Name

[Former Member]

Hello Experts,

My SAP server host (SAPGLOBALHOST) name is XYZ but configured full host name in RZ10 (icm/host_name_full ) as XYZ.ABC.COM.

Can I change SAP server host name to XYZ.ABC.COM?

If can, what are the steps I have to do for that?

Thanks in advance.

The hostname of the server should be XYZ only . You should not append the domain name to the actual hostname.

Just maintain the parameter SAPLOCALHOSTFULL to XYZ.ABC.COM using tcode RZ10. This would maintain the fully qualified hostname for the SAP system . If you set this , no need to set the parameter icm/host_name_full . ICM would use the qualified name from SAPLOCALHOSTFULL parameter.

Dear Ratnajit,

Thanks for your response .I donu2019t see any parameter like SAPLOCALHOSTFULL in RZ10 t-code. Can you please help me out where is that?

Hello Stars,

Please take a look at area "Setting the FQDN" in the below document about this parameter.

This is OK if not there in RZ10. You need to 'create' the one.

First verify the value using RZ11 for the parameter SAPLOCALHOSTFULL, if not set correct then create a new one in RZ10.

Alternative is to create or update this one - icm/host_name_full

Hi DB,

Thanks for your reply.

Issue: Whenever I execute BSP and webdynpro application then I need to maintain IP address and domain name in host file at each system (local pc) explicitly.

My understanding: Due to that, if I keep full host (icm/host_name_full) name and SAP server host(which is SAP software installed)name are same like XYZ.ABC.COM then I need not to make change in host file (each local pc).

Iu2019m not sure, is this right solution?

Please advice, if it is wrong.

Thanks.

Just have the following entry in the /etc/hosts file on the server . Also need to have the following entry in local PC as well if DNS is not configured.

<IP Address> XYZ XYZ.ABC.COM

and maintain the parameter SAPLOCALHOTSFULL to XYZ.ABC.COM in RZ10.

You should always have the qualified hostname in the URL for accessing these web applications.

Dear Ratnajit,

Ok thanks but DNS was not configured in XYZ server.

I want to execute the BSP/WDA web application without configuring IP address and domain name in host file at local system.

Could you please advise me any other alternate solution for this?

Thanks.

Hi pranendu,

Thanks for your reply.

Are u working in "Windows" envirment........    Yes

Could you please tell us the Landscape..................  

And kindly let us know what issue exactly you are facing (as you are going to change the Hostname)?

Here is the detailed description.

The issue is, I installed the SAP software without configuring DNS and my SAP host name is XYZ.

If I execute the BSP/WDA application without IP and domain name in local host file then IE displays u201Cpage cannot be displayedu201D. So that, I maintained host file configuration in each local PC.

Now, itu2019s working because I configured host file.

What are the steps need to be done to execute the web application (without configuring host file) ?

I'm not sure DNS configuration is must for this? Please advise.

Thanks.

In order to avoid using hosts file you will have to configure DNS server in your environment and make sure that all your client PC's can resolve SAP host name. DNS config is pretty easy and wont take much time.

PS using hosts files is a bad practice and can be very dangerous.

Hi Stars,

Could u please look into this link and find some needful..........

http://help.sap.com/saphelp_470/helpdata/en/9f/fc9c3b122efc6ee10000000a114084/content.htm

As per my opinion (have discussed with my colleague) it is mandatory to update the ETC/HOST file.......

Because to keep SAP application more secure we need to do the configuration like this ..............so that router have very clear

idea from which system it needs to accepet the request for "DIVERTING".

But still you can find out and OTHERS can also post or comment on my opinion.......So that I can also learn something,..........

Dear Alex,

Thanks for your reply.

I have couple of questions regarding this.

1.If I configured DNS then it will affect the SAP installation?

2.Do I execute the web application anywhere in IE (even mobile) after DNS configuration done?

Please guide me.

Thanks.

[Former Member]

Hi,

1. DNS Implementation will not affect your SAP installation at all. The only thing you will have to do is to register your SAP server host name in the DNS ... I assume this is non-domain installation if so then simply create new A host record in your DNS pointing to the SAP server IP address.

2. Yes you should be able to execute webdynpros from any PC that have this DNS server under its IPv4 settings. Try to ping SAP host from the user PC by host name and if you will get reply than you good to go

Hello,

what is your system version? Please, have a look at note 1275273 that explains how to change the hostname in 7.10 and 7.11 systems.

I hope this helps you.
