After applying the latest Firefox update (ESR version), you face some display issues on the HFM 11.1.2.x tabs
Starting Oracle EPM 18.104.22.168+, ODI is automatically installed with FDMEE. In addition to installing the FDMEE UI, it creates ODI repositories, installs the agent, sets it up as a service and configures it all to work together out of the box. The only thing missing is the installation of the ODI Studio.
It may happen during EPM configuration or after a restart that EPM Web Applications don’t start. Think system-jazn-data.xml!
