Error when using DBCA to create database Oracle XE 18c I am trying to create a new database using dbca.
Windows 10.
Please help me to find solution.


Here is the log
Sorry it took me a while to get back to this. I see at least two major issues in the trace.log:
First, it appears your environment is misconfigured:

and second, it appears that you do not have enough physical memory on your host to run a database:
