Error message: INS3105E Failure to install remote agent

This error occurs when you are installing a remote agent on a UNIX or Linux® system. .

Problem

You get this error message:

PM INS3105E: Host <fully_qualified_hostname> is associated 
with an invalid loopback IP 127.0.0.1

In the /etc/hosts file, the line for the specified IP address should be:

127.0.0.1   localhost.localdomain localhost

and not

127.0.0.1   <fully_qualified_hostname> <short_hostname>
  localhost.localdomain localhost

You should have a separate entry for the regular IP address and hostname of the IBM Spectrum Control server. For example:

9.47.98.63 <fully_qualified_hostname> <short_hostname>

The DB2® instance might not have stopped properly. Manually stop and restart DB2.
