While creating an Oracle 19c database I received this error:
Install Error [DBT-50000] Unable to check for available memory
After some research, I found the following workaround, to start the dbca with specific option:
dbca -J-Doracle.assistants.dbca.validate.ConfigurationParams=false
This fixed the error.
