I'm trying to install FMC on ESXi but I keep getting the following error:
DB error - wil retry: Cannot connect to DB at /usr/local/sf/lib/perl/5.10.1/SF/SFDBI.pm line 586
ESXi ver: 6.0.0
FMC ver: 6.2.0, also tried 6.2.3 but same error
This error is most likely due to insufficient resources.
Which ESXI version you are using? Try allocating more memory to the FMC. If the resources are shared then may be other apps are using those resources which FMC cannot take.
Try 12 GB or more memory
Hope it helps,
