这两天装了几套开发环境的Oracle数据库,其中有11.2.0.4的版本也有12.2.0.1的版本。由于网络环境复杂,没有办法使用图形界面的方式安装,只能使用静默方式安装,之前也写过关于静默安装数据库软件和创建实例的博客http://hbxztc.blog.51cto.com/1587495/1884833有兴趣的可以参考,这两天用的也是这样的方法,但是之前看到有人在分享中使用过dbca的静默方法来创建数据库实例,还没有做过尝试,趁安装空闲的时间研究了一下,在此也做一个简单的分享。
dbca有两种静默的安装实例的方式:一种是使用responseFile,另一种是直接使用命令行的方式。本次测试是用responseFile的方式。
使用responseFile方式自然需要有responseFile文件了,这个文件可以到database解压包目录下的response目录中找到,还可以在$ORACLE_HOME/assistants/dbca/目录下找到。文件名叫dbca.rsp。
创建流程:
1、复制一个dbca.rsp文件进行修改,来做为创建实例时使用。
[oracle@rhel6 dbca]$ pwd
/u01/app/oracle/product/11.2/db1/assistants/dbca
[oracle@rhel6 dbca]$ cp dbca.rsp /home/oracle
2、修改刚复制的dbca.rsp文件
这里解释部分文件中的参数
RESPONSEFILE_VERSION = "11.2.0" #指定版本号
OPERATION_TYPE = "createDatabase" #指定使用dbca要做的操作,这里要创建实例就选择createDatabase,如果要删除实例则为deleteDatabase
#创建实例有只需要修改创建实例部分的参数就可以了,看到#-----------------------*** End of CREATEDATABASE section ***------------------------部分就算是配置完了
[CREATEDATABASE]
GDBNAME = "dbs" #数据库的Global database name
SID = "dbs" #数据库的实例名
SYSPASSWORD = "123456" #指定sys用户密码
SYSTEMPASSWORD = "123456" #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
上面的参数是创建单实例时用到的参数,dbca.rsp文件中还有很多其他的参数,如果有进一步的需求可以自行修改相应的需求
3、开始创建数据库实例
执行下面的命令几分钟就可以创建一个实例:
[oracle@rhel6 11201]$ dbca -silent -responseFile /home/oracle/dbca.rsp

4、检查实例是否正常
[oracle@rhel6 11201]$ sqlplus / as sysdba

/home/oracle/11201/dbs/dbs/sysaux01.dbf
/home/oracle/11201/dbs/dbs/undotbs01.dbf
/home/oracle/11201/dbs/dbs/users01.dbf
这里简单说一下为什么这么快的原因,从alert日志中可以看到如下图的日志
从上图可以看出数据文件是被从copy中恢复出来的,而不是新创建的,这也可以解释为什么创建实例时第一行的日志是“Copying database files”的原因了。
说到这里也要说一下创建实例的三种类型,如下图:
从图中可以看出创建实例的三种类型,其中“General Purpose or Transaction processiong”和“Data Warehose”分别对应的是OLTP系统和数据仓库,它们后面的“Includes Datafiles”为Yes说明使用这两种方式创建时是用数据文件的备份来恢复出来的。最后修改字符集就可以 了。如下图alert日志
而“Custom Database”自定义模式则没有对应的数据文件来恢复,而是全新创建的数据文件,因此这种方式创建实例时耗费的时间也相对较长,因为需要跑数据字典。
上面简单介绍了使用responseFile方式创建实例的方法,另外一种方法是直接使用命令行,可以用dbca -h命令查看命令参数
