一 概述
假如一台服务器上已经安装了一个单机版的oracle实例orcl，这时想在这台服务器上再部署一个单机版的oracle实例ystat，则可以参考该文档进行部署。
二 操作步骤
2.1 创建相关目录
用root用户创建：
mkdir -p /u01/app/oracle/oradata/ystat
chown -R oracle:oinstall /u01/app/oracle/oradata/ystat
su - oracle
mkdir -p /u01/app/oracle/admin/ystat/adump
2.2 新建初始化参数文件
2.2.1 创建pfile文件
cd $ORACLE_HOME/dbs
vi initystat.ora
添加：
ystat.__db_cache_size=4395630592
ystat.__java_pool_size=33554432
ystat.__large_pool_size=50331648
ystat.__oracle_base='/u01/app/oracle'#ORACLE_BASE set from environment
ystat.__pga_aggregate_target=2969567232
ystat.__sga_target=5519704064
ystat.__shared_io_pool_size=0
ystat.__shared_pool_size=956301312
ystat.__streams_pool_size=33554432
*.audit_file_dest='/u01/app/oracle/admin/ystat/adump'
*.audit_trail='db'
*.compatible='11.2.0.4.0'
*.control_files='/u01/app/oracle/oradata/ystat/control01.ctl','/u01/app/oracle/oradata/ystat/control02.ctl'
*.db_block_size=8192
*.db_domain=''
*.db_name='ystat'
*.diagnostic_dest='/u01/app/oracle'
*.dispatchers='(PROTOCOL=TCP) (SERVICE=ystatXDB)'
*.memory_target=16489271296
*.nls_language='SIMPLIFIED CHINESE'
*.nls_territory='CHINA'
*.open_cursors=300
*.processes=300
*.remote_login_passwordfile='EXCLUSIVE'
*.sessions=335
*.undo_tablespace='UNDOTBS1'2.2.2 创建spfile文件
[oracle@XYSHQ-ORACLE dbs]$ export ORACLE_SID=ystat
[oracle@XYSHQ-ORACLE dbs]$ sqlplus / as sysdba
SQL*Plus: Release 11.2.0.4.0 Production on 星期五 8月 13 09:21:31 2021
Copyright (c) 1982, 2013, Oracle. All rights reserved.
已连接到空闲例程。
SQL> create spfile from pfile;
文件已创建。
会看到在$ORACLE_HOME/dbs路径下生成了spfileystat.ora文件。
2.3 将数据库启动到nomount状态
SQL> startup nomount;
ORACLE 例程已经启动。

2.4 创建数据库
CREATE DATABASE ystat

SIZE 200M REUSE AUTOEXTEND ON MAXSIZE UNLIMITED;示例：
创建完数据库后，数据库自动启动到了open状态：
2.5 执行创建数据字典等脚本
@?/rdbms/admin/catalog.sql
@?/rdbms/admin/catproc.sql
@?/sqlplus/admin/pupbld.sql
--输出内容略，大约需执行5-10分钟。
2.6 修改listener.ora和tnsnames.ora
cd $ORACLE_HOME/network/admin
vi listener.ora，添加：
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = orcl)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
(SID_NAME = orcl)
)
(SID_DESC =
(GLOBAL_DBNAME = ystat)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
(SID_NAME = ystat)
)
)
vi tnsnames.ora
添加如下内容：
YSTAT =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = XYSHQ-ORACLE)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = ystat)
)
)
注意：HOST= XYSHQ-ORACLE这里记得根据实际情况改成自己服务器的主机名。
#重启监听
lsnrctl stop
lsnrctl start
2.7 设置新instance开机自启动
用root用户修改/etc/oratab,添加一行：
ystat:/u01/app/oracle/product/11.2.0/dbhome_1:Y
2.8 创建ystat表空间
#登录统计数据库su - oracleexport ORACLE_SID=ystatsqlplus / as sysdba
#创建表空间
create tablespace ystat datafile '/u01/app/oracle/oradata/ystat/ystat.dbf' size 30G autoextend on;
2.9 创建ystat用户
create user ystat identified by ystat_sys;grant connect,resource to ystat;
grant dba to ystat;
2.10 扩容表空间
alter tablespace system add datafile '/u01/app/oracle/oradata/ystat/system02.dbf' size 30G autoextend on;
alter tablespace temp add tempfile '/u01/app/oracle/oradata/ystat/temp02.dbf' size 30G autoextend on;
