hostName: hostName is not a properly formed host name.

I saw this exception earlier: -

hostName: hostName is not a properly formed host name.

when creating a WAS profile: -

/opt/IBM/WebSphere/AppServer/bin/manageprofiles.sh -create -templatePath /opt/IBM/WebSphere/AppServer/profileTemplates/management -profileName Dmgr01 -nodeName Dmgr -isDefault -enableAdminSecurity true -adminUserName wasadmin -adminPassword passw0rd

Initially I was stumped, as the command doesn't specify a hostname.

Then I thought about it …..

…. and looked at the hostname of my server: -

hostname

mta2015_1.uk.ibm.com

and remembered that, whilst instantiating a VM in the cloud earlier, I was told off for using a hostname containing an underscore character.

I changed the hostname to be more in keeping with my target - IBM ODM 8.7 i.e. to: -

odm87.uk.ibm.com

and, quelle surprise, all is now well :-)
