一次耗时4天的oracle安装过程

服务端部署

平台环境

Linux系统：centos7.5 kernel：3.10.0-862.el7.x86_64

Oracle版本：oracle-database-ee-19c

因为oracle19对linux内核有版本要求，所以选择centos7.5

Oracle下载地址

oracle-database-preinstall-19c：

开始安装

1.

#yum -y localinstall oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm

#yum -y localinstall oracle-database-ee-19c-1.0-1.x86_64.rpm

#/etc/init.d/oracledb_ORCLCDB-19c configure

安装完毕，开始进行配置

Oracle的安装目录为：/opt/oracle/

2.配置环境变量，切换到oracle用户下

#su - oracle

vim .bash_profile

export ORACLE_HOME=/opt/oracle/product/19c/dbhome_1

export PATH=$PATH:/opt/oracle/product/19c/dbhome_1/bin

export ORACLE_SID=ORCLCDB

#source .bash_profile

3.登录oracle数据库

#sqlplus / as sysdba

4.创建用户，授权，参考网上

这里创建用户名时，其实不需要加c##的前缀。

5.登录之后，这里存在一个问题，需要改正

SQL> connect sys/sys as sysdba

Connected.

SQL> show parameter case

NAMETYPEVALUE

------------------------------------ ----------- ------------------------------

sec_case_sensitive_logonbooleanFALSE

SQL> ALTER SYSTEM SET SEC_CASE_SENSITIVE_LOGON=TRUE SCOPE=BOTH SID='*';

System altered.

SQL> connect C##TEST/test

Connected.

原因如下：

我在这之前创建了C##TEST这个用户，

1.

我去查看了用户表，发现用户表中存放的用户名全部为大写，即使你创建的时候是小写的，所以，登录的时候要使用大写的用户名

6.用户登录之后，开启监听

SQL> startup

ORA-32004: obsolete or deprecated parameter(s) specified for RDBMS instance

ORACLE instance started.
