Issue/Introduction

Description:

At some time you may need to change the hostname of the SpectroSERVER. Once the hostname is changed on the server, the same should be updated in Spectrum application as well. This can be done by means of a perl script and some additional configuration changes.

Solution:

In order to update the new hostname in the Spectrum configuration files we need to follow the below process

1. Stop the SpectroSERVER and its services from processd.
2. Make sure processd is configured to start manually.
3. Change the hostname on the server.
4. Reboot the box.
5. Run the below script from the command line.
   
   

                          ChangeHostname_Spectrum.pl <new hostname>                       Output:                                    ChangeHostname_Spectrum.pl new_hostname                                   Updating .hostrc                                   Updating .installrc                                   Updating UI-CONFIG.testme                                   Updating LS/.locrc                                   Updating LS/.natfwrc                                   Updating SS/.natfwrc                                   Updating SS/DDM/.natfwrc                                   Updating bin/VBNS/.natfwrc                                   Updating SG-Support/CsResource/preferences/ssroe.prf                                   Updating tomcat/webapps/spectrum/META-INF/context.xml                                   Updating vnmsh/.vnmshrc                                   Completed conversion

6. Open a bash shell on the SpectroSERVER.
7. cd lib/SDPM
8. ./processd --remove
9. ./processd --install --username <domain>\<username> --password <password> (Don't input the domain if your server was not in the domain)
10. ./processd --start

Now you should be able to start processd and SpectroSERVER successfully with the new hostname.
