If you're planning to install an EPM 22.214.171.124 environment where HFM web components are running on two web servers you should definitely pick up the following patch from Oracle Support:
- Shared Services 126.96.36.199.000 Patch Set Exception (PSE): 13240594
The patch fixes (among a few other things) an issue with the clustered OHS (Oracle HTTP Server) ProxyPass configuration which is automatically created by EPM System Configurator. The incorrect configuration caused me quite a few head-scratching moments before I found out about the HSS patch as it messes up cookie handling for LCM and potentially also for some other web applications. So be sure to apply this and follow the instructions in the readme file carefully!
