|---|---|
| Linux版本： | Red Hat Enterprise Linux Server release 7.9 (Maipo) |
| 主机名： | ace-test-84 |

1.2.安装前准备二
1.2.1.创建用户组
-- 创建用户组
[root@ace-test-84 ~]$ groupadd -g 5001 oinstall
[root@ace-test-84 ~]$ groupadd -g 5002 dba1.2.2.删除用户组（拓展）
-- 删除用户组
[root@ace-test-84 ~]$ groupdel test
-- 如果组里面有用户需要先删除用户或移动用户，才能删除组
[root@ace-test-84 ~]$ userdel test ###删除用户1.2.3.创建oracle用户
#创建oracle用户—编号为6001，默认组为oinstall ，并添加到dba组，主要是oinstall组发生作用
[root@ace-test-84 ~]$ useradd -u 6001 -g oinstall -G dba oracle1.2.4.修改oracle得密码
# passwd oracle ----设置oracle用户密码（Zyl@0411）[root@ace-test-84 ~]$ passwd oracle
Changing password for user oracle.
New password:
Retype new password:
passwd: all authentication tokens updated successfully.1.2.5. 检查创建的oracle用户
#检查创建的oracle用户
[root@ace-test-84 ~]$ su - oracle
[oracle@ace-test-84 ~]$ id
uid=6001(oracle) gid=5001(oinstall) groups=5001(oinstall),5002(dba)
[oracle@ace-test-84 ~]$ 2.查看环境
[oracle@ace-test-84 ~]$ cat .bash_profile
# .bash_profile# Get the aliases and functions
if [ -f ~/.bashrc ]; then. ~/.bashrc
fi# User specific environment and startup programsPATH=$PATH:$HOME/.local/bin:$HOME/binexport PATHexport TMP=/tmp
export TMPDIR=$TMP
export ORACLE_SID=tstttdp1
export ORACLE_BASE=/oracle/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/19.3.0/db_1
export PATH=/usr/sbin:$PATH
export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
stty erase ^H
[oracle@ace-test-84 ~]$ echo $ORACLE_HOME
/oracle/app/oracle/product/19.3.0/db_1[oracle@ace-test-84 ~]$ echo $ORACLE_BASE
/oracle/app/oracle
[oracle@ace-test-84 ~]$ 3.创建新的实例名
首先设置要创建的ORACLE的SID
[oracle@ace-test-84 ~]$ export ORACLE_SID=dcpfareint4.创建初始化文件
cd $ORACLE_HOME/dbs目录下
命名方法：init+实例名.ora 本例中initdcpfareint
[oracle@ace-test-84 ~]$ cd $ORACLE_HOME/dbs
[oracle@ace-test-84 dbs]$ vi initdcpfareint.ora# 添加如下内容：
dcpfareint.__data_transfer_cache_size=0
dcpfareint.__db_cache_size=72209137664

*.undo_tablespace='UNDOTBS1'注意：
1.不要用原来的<ORACLE_BASE>作为路径，修改为对应的绝对路径，否则会报错2.注意control_files 应该是新的文件，否则会报文件已存在的错误
5.创建密码文件
orapwd file=$ORACLE_HOME/dbs/orapw+实例名 password=sys的密码 entries=16 force=y
[oracle@ace-test-84 ~]$ orapwd file=$ORACLE_HOME/dbs/orapwdcpfareint password=AFuwd7_@5K entries=16 force=y6.创建相应的目录
[oracle@ace-test-84 ~]$ mkdir -p /oracle/app/oracle/oradata/ORCL/controle
[oracle@ace-test-84 ~]$ mkdir -p /oracle/app/oracle/oradata/ORCL/dataFile
[oracle@ace-test-84 ~]$ mkdir -p /oracle/app/oracle/oradata/ORCL/redoLog7.启动新建实例的数据库状态为nomount
切换到新建的实例下面，然后使用数据库的静态文件启动数据库到nomount状态
注意：
使用静态文件启动的nomount状态前，需要先创建审计目录
执行：STARTUP NOMOUNT PFILE= '/oracle/app/oracle/product/19.3.0/db_1/dbs/initdcpfareint.ora'; 前，
需要先创建下面的路径才行，不然报错
mkdir -p /oracle/app/oracle/admin/dcpfareint/adump
7.1.创建审计目录
[oracle@ace-test-84 ~]$ mkdir -p /oracle/app/oracle/admin/dcpfareint/adump7.2.切换到新建的实例环境下，然后使用静态文件启动到nomount状态下
[oracle@ace-test-84 ~]$ export ORACLE_SID=dcpfareint

9.1.执行下面的命令
执行下面命令：
SQL> @?/rdbms/admin/catalog.sql; --创建数据库的统计视图，审计视图
SQL> @?/rdbms/admin/catproc.sql; -- 数据库具有pl/sql的使用功能。 生成同义词典表与相应视图的架构表（最重要的，建库必须运行的）
SQL> @?/rdbms/admin/catexp.sql; --数据库具有导入导出功能，即可以使用exp、imp、expdp、impdp
SQL> @?/rdbms/admin/utlrp.sql --编译
SQL> @?/sqlplus/admin/pupbld.sql --system运行
SQL> @?/rdbms/admin/cataudit.sql --创建审计数据字典视图@?/rdbms/admin/catjobq.sql --创建关于job的视图
@?/rdbms/admin/dbmsutil.sql --针对的是DBMS_SYSTEM GRANT EXECUTE ON DBMS_SYSTEM TO username;@?/rdbms/admin/utlsampl.sql --生成一个系统事例默认的用户名与密码（用户名为scott密码为tiger）从oracle7开始一直就有了。9.2.打开数据库
SQL> ALTER DATABASE MOUNT;
SQL> ALTER DATABASE OPEN;10.修改监听配置文件listener.ora
到$ORACLE_HOME/network/admin目录下：vi listener.ora
LISTENER =(DESCRIPTION_LIST =(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = ace-test-84)(PORT = 1521))(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))))11.修改配置tns文件
到$ORACLE_HOME/network/admin目录下：vi tnsnames.ora
LISTENER_DCPFAREI =(ADDRESS = (PROTOCOL = TCP)(HOST = ace-test-84)(PORT = 1521))TSTTTDP1 =(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = ace-test-84)(PORT = 1521))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = tstttdp1)))DCPFAREI = ---这个名字随便
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = ace-test-84)(PORT = 1521)) -- IP地址，如果使用hostname的话，需要在/etc/hosts 添加 10.10.10.212 ace-test-84
(CONNECT_DATA =
(SERVER = DEDICATED) ---连接方式，这里是专用
(SERVICE_NAME = dcpfarei) -- 服务名
)
)
12.配置好tns后，数据库启动监听的时候，监听不到新建的服务，需要执行下面的操作
注册动态监听
SQL> alter system set LOCAL_LISTENER='(ADDRESS=(PROTOCOL=TCP)(HOST=10.211.129.51)(PORT=1521))' sid='dcpfareint';System altered.
SQL> alter system register;System altered.执行上面的操作后，动态参数的变化：
vi spfiledcpfareint.ora
执行前：
*.local_listener='LISTENER_DCPFAREINT'执行后：
*.local_listener='LISTENER_DCPFAREINT'
dcpfareint.local_listener='(ADDRESS=(PROTOCOL=TCP)(HOST=10.10.10.212)(PORT=1521))'
13.启动监听
-- 启动监听
[oracle@ace-test-84 ~]$ lsnrctl start
-- 查看监听的状态
[oracle@ace-test-84 ~]$ lsnrctl status
-- 停止监听
[oracle@ace-test-84 ~]$ lsnrctl stop
-- 重启监听
[oracle@ace-test-84 ~]$ lsnrctl reload14.启停实例
[oracle@ace-test-84 ~]$ export ORACLE_SID=dcpfareint
[oracle@ace-test-84 ~]$ sqlplus / as sysdbaSQL*Plus: Release 19.0.0.0.0 - Production on Wed Jun 26 16:34:32 2024

至此，Linux新建实例结束
