昨天有个需求，需要用命令行建一个RAC。先Google了一些文章，最好参照了下面这篇。
Create RAC database using DBCA silent mode，感谢此文作者，写得非常简洁。
我的环境是19c, 2节点RAC。然后遇到了一系列错误。
第一个错误，Disk Group不存在：
[FATAL] [DBT-06002] Selected disk group (XXXX) is not found.ACTION: Specify a disk group that is accessible from the system.
正好，主机上还有其它数据库，查询一下：
SQL> select name from v$asm_diskgroup;NAME------------------------------DATAC1RECOC1
然后改成以下：
-diskGroupName +DATAC1/{DB_UNIQUE_NAME}/ \
第2个错误，FRA地址无效，可以绕过问题或指定FRA位置，我用了后者。
[WARNING] [DBT-06303] Unable to check if location (FRA/db0623/) is on ACFS.[FATAL] [DBT-06007] The specified location (FRA Location) is invalid.CAUSE: The specified location is not found on the system or is detected to be a file.
直接去掉以下行：
-recoveryAreaDestination FRA \
或者改为：
-recoveryAreaDestination +$FRA \
第3个错误，4G以上不能AMM管理以及字符集问题：
[FATAL] [DBT-11211] The Automatic Memory Management option is not allowed when the total physical memory is greater than 4GB.CAUSE: The current total physical memory is 754GB.[FATAL] [DBT-11152] National character set specified (AL32UTF8) is invalid.
直接删除以下行：
-nationalCharacterSet AL32UTF8 \-automaticMemoryManagement true \
最终命令如下，会自动创建一个PDB orclpdb1。其中node01和node02是两个RAC节点的主机名，通过hostname命令获取。
export DBPWD='ABcd123_#'export DGNAME=DATAC1export FRA=RECOC1export DBNAME=db0623export NODE1=node01export NODE2=node02dbca -silent \-createDatabase \-databaseConfigType RAC \-templateName General_Purpose.dbc \-gdbName $DBNAME \-sid $DBNAME \-SysPassword $DBPWD \-SystemPassword $DBPWD \-emConfiguration NONE \-redoLogFileSize 2048 \-storageType ASM \-asmSysPassword $DBPWD \-diskGroupName +$DGNAME/{DB_UNIQUE_NAME}/ \-recoveryAreaDestination +$FRA \-totalMemory 10240 \-databaseType MULTIPURPOSE \-nodelist ${NODE1},${NODE2} \-createAsContainerDatabase true \-numberOfPDBs 1 \-pdbName orclpdb1 \-pdbAdminPassword $DBPWD
日志如下，18分钟还是蛮快的：

另外两次也是18分钟左右，比较一致：

删除，此时数据库是打开状态:
dbca -silent -deleteDatabase -sourceDB db0623
输出：
$ dbca -silent -deleteDatabase -sourceDB db0623Enter SYS user password:[WARNING] [DBT-19202] The Database Configuration Assistant will delete the Oracle instances and datafiles for your database.

最后，附上一个帮助：
