重启操作系统
shutdown -r now
安装数据库软件，不建库
1.编辑db_install.rsp文件，可以拷贝一份出来，把原来的清理掉，然后输入以下内容：
oracle.install.responseFileVersion=/oracle/install/rspfmt_dbinstall_response_schema_v11_2_0
oracle.install.option=INSTALL_DB_SWONLY
ORACLE_HOSTNAME=crm_db
UNIX_GROUP_NAME=oinstall
INVENTORY_LOCATION=/home/app/oraInventory
SELECTED_LANGUAGES=en
ORACLE_HOME=/home/app/oracle/product/11.2.0/db_1
ORACLE_BASE=/home/app/oracle
oracle.install.db.InstallEdition=EE
oracle.install.db.EEOptionsSelection=false
oracle.install.db.DBA_GROUP=dba
oracle.install.db.OPER_GROUP=oinstall
oracle.install.db.config.starterdb.type=GENERAL_PURPOSE
oracle.install.db.config.starterdb.globalDBName=oracrm
oracle.install.db.config.starterdb.SID=oracrm
oracle.install.db.config.starterdb.characterSet=AL32UTF8
oracle.install.db.config.starterdb.memoryOption=true
oracle.install.db.config.starterdb.memoryLimit=40960
oracle.install.db.config.starterdb.password.ALL=oracle
oracle.installer.autoupdates.option=SKIP_UPDATES
#iSECURITY_UPDATES_VIA_MYORACLESUPPORT=false
DECLINE_SECURITY_UPDATES=true
2，看到让用root用户执行两个脚本的提示后，把脚本执行完，软件就安装完成了。
创建数据库：
编辑dbca.rsp
脚本：
[GENERAL]
RESPONSEFILE_VERSION = "11.2.0"
OPERATION_TYPE = "createDatabase"
[CREATEDATABASE]
GDBNAME = "oracrm"
SID = "oracrm"
TEMPLATENAME = "General_Purpose.dbc"
CHARACTERSET = "AL32UTF8"
netca /silent /responseFile /home/oraclesoftware/netca.rsp
