下面为您介绍的Oracle创建实例的方法是在unix下Oracle创建实例的方法，如果您对Oracle创建实例方面感兴趣的话，不妨一看。
#unix系统存储：逻辑卷组--》逻辑卷---》文件系统---》文件夹---》文件
#查看逻辑卷
vgdisplay
#一般有三个逻辑卷组
#/dev/vg00（系统逻辑卷） /dev/vgitapp（应用逻辑卷） /dev/vgitdb（数据存储逻辑卷）
#创建逻辑卷 hp-ux
lvcreate -L 120000 -n lv_itsmdb01 /dev/vgitdb
# 120000 单位是：m
#创建文件系统
newfs -F vxfs /dev/vgitdb/rlv_itsmdb01
#路径根据oracel安装目录进行相应修改
创建目录/oracle/app/oracle/oradata执行组和用户为dba和oracle
#mount文件系统
#路径根据oracel安装目录进行相应修改
mount -F vxfs /dev/vgitdb/lv_itsmdb01 /oracle/app/oracle/oradata
#oracle帐户登录系统
#建文件夹
- mkdir /oracle/admin/itsm3/cdump /oracle/admin/itsm3/udump /oracle/admin/itsm3/logs /oracle/admin/itsm3/bdump

- spool $ORACLE_BASE/admin/itsm3/logs/Createitsm3.log
#如没有Createitsm3.log，自己创建这个文件
startup nomount pfile=$ORACLE_HOME/dbs/inititsm3.ora
#自己创建inititsm3.ora（内容从其他的实例下寻找，之后修改），执行此命令后若报错，一般都是文件夹没有，或者创建未知不对，自行查找对应

#$ORACLE_SID 是环境变量，通过设置.profile 得到，可以写成绝对路径 如：/oracle/../.. 点对应你自己建的目录
