Solution 1
Add the following parameter to bypass the error:
dbca -J-Doracle.assistants.dbca.validate.ConfigurationParams=false &
Solution 2
This error as it says, indicate that the "DBCA" can not check for available memory. This happens when "DBCA" does not have permission to check.
To bypass this error, run your Command Prompt as Administrator before lunching "DBCA".
Solution 3
Bypass via advanced setup
Run DBCA as admin and work your way through the advanced setup. I think this issue is avoided because it lets you manually enter, or use recommended defaults, for the memory section.
