已有数据库（单机）部署Database Vault

1.停止em和数据库
emctl stop dbconsole
shutdown immediate
2.又一次安装DB软件
./runInstaller
选组件的时候，选中“Oracle database vault option”

3.改动环境变量
改动ORACLE_HOME
4.改动/etc/oratab中的ORACLE_HOME
5.从原来的HOME拷贝必要文件到现有HOME
[oracle@single1 admin]$ pwd
/u01/app/oracle/product/11.2.0/dbhome_1/network/admin
[oracle@single1 admin]$ cp tnsnames.ora /u01/app/oracle/product/11.2.0/dbhome_3/network/admin/

[oracle@single1 dbs]$ pwd
/u01/app/oracle/product/11.2.0/dbhome_1/db
[oracle@single1 dbs]$ cp initsingle2.ora /u01/app/oracle/product/11.2.0/dbhome_3/dbs/

[oracle@single1 dbs]$ cp orapwsingle2 /u01/app/oracle/product/11.2.0/dbhome_3/dbs/

[oracle@single1 dbs]$ cp spfilesingle1.ora /u01/app/oracle/product/11.2.0/dbhome_3/dbs/
[oracle@single1 dbs]$ cp init.ora /u01/app/oracle/product/11.2.0/dbhome_3/dbs/

6.启动数据库
startup

7.假设有EM，需重建
