When looking in the top right corner of the Failed Event Manager, the following error is displayed:
The Recovery sub-system is disabled.
Enable the Recovery sub-system in order
to work with failed events.
You get directed to the following tech-note:
which states that there is a problem with the Failed Event Manager MBean in your server/cluster.
Interestingly, when the failed event manager EAR is installed manually (or via script) in 6.0.2.x the MBeans are not automatically installed for you. You have to go back to your server configuration and configure them manually. When you create a profile using the profile creation wizard, everything is fine.
