Linux下静默创建Oracle数据库实例，CentOS7下静默创建Oracle数据库实例

前提是Oracle静默安装已经成功

1.先在安装/data/app/oracle/product/11.2.0/dbhome_1/assistants/dbca目录下的dbca.rsp文件复制到 /home/oracle(这个文件可以任意指定，建议使用此目录)

2.修改配置文件（就是刚刚复制到/home/oracle目录下的dbca.rsp文件）

RESPONSEFILE_VERSION = "11.2.0"  

OPERATION_TYPE = "createDatabase"  


[CREATEDATABASE]

GDBNAME = "dbs"  
SID = "dbs"  

SYSPASSWORD = "1234qwer"  #指定sys用户密码

SYSTEMPASSWORD = "1234qwer" #指定system用户密码

DATAFILEDESTINATION =/home/oracle/11201/dbs #指定数据文件存放的目录

CHARACTERSET = "ZHS16GBK"  #指定字符集

NATIONALCHARACTERSET= "AL16UTF16"  #指定国家字符集

DATABASETYPE = "OLTP"  #指定实例的类型

AUTOMATICMEMORYMANAGEMENT = "TRUE" #指定使用自动内存管理

TOTALMEMORY = "800"  #指定使用内存的大小，单位是MB

===============================================================================

根据以上的信息来找到文件内容，如下，直到找到TOTALMEMORY = "800"就OK了

最后执行这命令

dbca -silent -responseFile /home/oracle/dbca.rsp

完成结果如下：
