Information in this document applies to any platform.
When upgrading to 19c on systems using RDS protocol (vs. UDP), cluvfy pre-checks will fail in ASM instance. The issue can be worked around, and there is fix for cluvfy.
Note that this error message can lead to someone changing IPC protocol from RDS to UDP.
This is typically not supported in systems that use Exadata Storage Cells over InifiniBand networks and can lead to extended performance problems and outages.
Please do not relink due to this error.
