SPC-OCA-10382: The parent landscape does not exist in the location server map for the local landscape

Issue/Introduction

You migrated your monitoring environment to new servers.  You moved the MLS, various SpectroSERVERs and OneClicks successfully but you have problem with one of the landscape servers(remote SpectroSERVERs). 

To achieve this, you adjusted the /etc/hosts files and restarted the services, since Spectrum mostly uses the hostname and only the IP of the MLS and OneClicks changed. This worked well for two SpectroSERVERs, but it is failing with the last one. You followed the same steps as with the others, but we do not see the landscape in OneClick.

 

Environment

Distributed Spectrum System on Linux servers.

Cause

Linux is case sensitive so the hostnames in the .hostrc and OS etc hosts files need to match exactly how the servers are displayed by the OS.  For example, if the hostname command returns netops-ss and we have NETOPS-SS in the .hostrc, Linux see these as 2 different servers and they will not be able to communicate in a Spectrum DSS.  

This problem is not seen in a Windows environment.

Resolution

A simple "hostname" command run from a bash shell of each of SpectroSERVERs in Linux will confirm if they should be uppercase or lowercase.  This should be verified on all SpectroSERVERs and Oneclick server in a DSS and listed as such in the .hostrc and /etc/hosts files.
