IBM Installation Manager - Permission to Launch

I had some fun and games with IBM Installation Manager 1.6.0 today ( on a 64-bit version of Red Hat Enterprise Linux 6.3, but that's not important right now ).

It all stemmed from when I ( stupidly ) tried to run IIM as root, having installed and configured it as a non-root user - wasadmin.

This is what I saw: -

ERROR: The Installation Manager cannot be started.The registry information does not exist or does not match with this executable.This may happen if you are trying to run Installation Manager installed by another user.

00:00.40 ERROR [main] com.ibm.cic.agent.internal.application.HeadlessApplication run
  The Installation Manager cannot be started.The registry information does not exist or does not match with this executable.This may happen if you are trying to run Installation Manager installed by another user.

However, when I then tried to run IIM as wasadmin: -

$ /opt/IBM/InstallationManager/eclipse/IBMIM -version -nosplash -silent

I got this: -

I thought this might be a permissions issue as, having run IIM as root, I'd locked out certain crucial files, thus preventing wasadmin from accessing them.

I validated this as follows: -

$ /opt/IBM/InstallationManager/eclipse/tools/imcl -version -silent -nosplash

which returned: -

Invalid Configuration Location:
Locking is not possible in the directory "/opt/IBM/InstallationManager/eclipse/configuration/org.eclipse.osgi". A common reason is that the file system or Runtime Environment does not support file locking for that location. Please choose a different location, or disable file locking passing "-Dosgi.locking=none" as a VM argument. 
/opt/IBM/InstallationManager/eclipse/configuration/org.eclipse.osgi/.manager/.fileTableLock (Permission denied)

When I checked that file: -

$ ls -al /opt/IBM/InstallationManager/eclipse/configuration/org.eclipse.osgi/.manager/.fileTableLock 

I saw this: -

-rw-r--r-- 1 root root 0 Jan 25 09:29 /opt/IBM/InstallationManager/eclipse/configuration/org.eclipse.osgi/.manager/.fileTableLock

The same was true of other files in the same location: -

$ ls -al /opt/IBM/InstallationManager/eclipse/configuration/org.eclipse.osgi

Once I changed the permissions: -

$ chown -R wasadmin:wasadmins /opt/IBM/InstallationManager/

all was well: -

$ /opt/IBM/InstallationManager/eclipse/tools/imcl -version -silent -nosplash

Installation Manager (installed)

Internal Version: 1.6.0.20120831_1216

$ /opt/IBM/InstallationManager/eclipse/IBMIM -version -nosplash -silent
