许久没有用 Silent 方式建库了，非常顺畅，建立一个 12.2 非多租户的数据库：
[oracle12c@iz2zeezinabu7k6olgelwez ~]$ dbca -silent -createDatabase \\
> -templateName General_Purpose.dbc \\
> -gdbname eygle -sid eygle -responseFile NO_VALUE \\
> -characterSet AL32UTF8 \\
> -sysPassword OraPasswd1 \\
> -systemPassword OraPasswd1 \\
> -createAsContainerDatabase false \\
> -databaseType MULTIPURPOSE \\
> -automaticMemoryManagement false \\
> -totalMemory 1536 \\
> -storageType FS \\
> -datafileDestination "/u01/oracle12c/db/oradata/" \\
> -redoLogFileSize 50 \\
> -emConfiguration NONE \\
> -ignorePreReqs

Look at the log file "/u01/oracle12c/db/cfgtoollogs/dbca/eygle/eygle.log" for further details.
如果是多租户，增加几个参数，类似如下：
dbca -silent -createDatabase \\
-templateName General_Purpose.dbc \\
-gdbname cdb01 -sid cdb01 -responseFile NO_VALUE \\
-characterSet AL32UTF8 \\
-sysPassword OraPasswd1 \\
-systemPassword OraPasswd1 \\
-createAsContainerDatabase true \\
-numberOfPDBs 1 \\
-pdbName pdb3 \\
-pdbAdminPassword OraPasswd1 \\
-databaseType MULTIPURPOSE \\
-automaticMemoryManagement false \\
-totalMemory 1536 \\
-storageType FS \\
-datafileDestination "/u01/app/oracle/oradata/" \\
-redoLogFileSize 50 \\
-emConfiguration NONE \\
-ignorePreReqs
操作很简单.
