Hello Asi,
We may need a support case to fix this anyway, but if you want to discuss it via the community site, the first thing is to confirm the install was complete and error free.
If uncomfortable sharing machine information and log files, I would recommend opening a new support case for review of the system.
Look in (default path) /opt/CA/PerformanceCenter/InstallLogs. There should be 6 logs there. One each for MySql, SSO service, Event Manager service, Device Manager service, Console service, and lastly the main high level "Performance_Center_Install" file.
Near the top of each file we should see a section similar to this:
Summary
-------
Installation: Successful.
227 Successes
0 Warnings
0 NonFatalErrors
0 FatalErrors
Do any of them show anything besides Successes?
Thanks,
Michael
