I want to experiment with NoSql database. I'm trying to create a database according to the instructions
https://docs.oracle.com/cd/E26161_02/html/AdminGui...
However, during step 1, an error occurs Exception in thread "main" java.lang.NoClassDefFoundError: com/sleepycat/ je/CacheMode

                                                  -num_cpus 1 \
                                                  -memory_mb 1000 \
                                                  -store-security none

I've googled and it feels like I'm the only one with this problem.
