WebSphere Application Server Network Deployment - More Like Notwork Deployment ...

Having taken the default option to install WebSphere Application Server Network Deployment 7.0.0.0 ( then upgraded to 7.0.0.9 ) with a Deployment Manager profile, I'm now in the process of setting up said DM before federated an instance of WebSphere Portal 6.1.5.1 ( installed on the same node ) into the cell.

When I attempted to start the DM, using the command: -

/opt/IBM/WebSphere/AppServer/profiles/Dmgr01/bin/startManager.sh

but this failed pretty darn quickly with: -

ADMU3011E: Server launched but failed initialization. startServer.log,
           SystemOut.log(or job log in zOS) and other log files under
           /opt/IBM/WebSphere/AppServer/profiles/Dmgr01/logs/dmgr should
           contain failure information.

When I looked in SystemOut.log, I saw: -

DCSV9403E: Received an illegal configuration argument. Parameter MulticastInterface, value: 127.0.1.1. Exception is java.lang.Exception: Network Interface 127.0.1.1 was not found in local machine network interface list. Make sure that the NetworkInterface property is properly configured!

Now my /etc/hosts currently looks like this: -

127.0.0.1    localhost
127.0.1.1    dmhw500.uk.ibm.com    dmhw500

# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

However, according to this Blog post, that might be the problem.

Following the recommendations in the posting, I changed the relevant part of /etc/hosts to: -

127.0.0.1    localhost        dmhw500
127.0.1.1    dmhw500.uk.ibm.com    dmhw500

and am now able to start the Deployment Manager.

Let's see how I get on ...

***UPDATE 28 December 2011***

Using WebSphere Application Server ND 7.0.0.17 on Ubuntu 11.10, I needed to further amend /etc/hosts to: -

127.0.0.1       localhost               dmhw500         dmhw500.uk.ibm.com
127.0.1.1       dmhw500.uk.ibm.com      dmhw500

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

in order to overcome these errors: -

[28/12/11 19:17:54:584 GMT] 00000000 HostNameMap   W   HMGR0064W: Resolution of IP Addresses for host name dmhw500.uk.ibm.com found only the loopback address. The loopback address will be used.
[28/12/11 19:17:55:006 GMT] 00000000 LogAdapter    E   DCSV9403E: Received an illegal configuration argument. Parameter MulticastInterface, value: 127.0.1.1. Exception is java.lang.Exception: Network Interface 127.0.1.1 was not found in local machine network interface list. Make sure that the NetworkInterface property is properly configured!

Once I did this, I was able to run startManager.sh etc.
