一台服务器上安装多个不同版本的oralce

环境:
OS:Centos 6.9

服务器1台
目前已经在运行了oralce 11g 安装目录/u01
计划安装12c,安装目录u02

 

新用户使用oracle01账号，该账号需要与oralce账号同在相同的组(dba,oinstall)

 

1.安装提示要执行的脚本:

[root@localhost db]# /u02/app/oracle/product/12.2.0.1/db_1/root.sh
Performing root user operation.

The following environment variables are set as:
    ORACLE_OWNER= oracle01
    ORACLE_HOME=  /u02/app/oracle/product/12.2.0.1/db_1

Enter the full pathname of the local bin directory: [/usr/local/bin]: 
The file "dbhome" already exists in /usr/local/bin.  Overwrite it? (y/n) 
[n]: 
The file "oraenv" already exists in /usr/local/bin.  Overwrite it? (y/n) 
[n]: 
The file "coraenv" already exists in /usr/local/bin.  Overwrite it? (y/n) 
[n]: 

Entries will be added to the /etc/oratab file as needed by
Database Configuration Assistant when a database is created
Finished running generic part of root script.
Now product-specific root actions will be performed.
Do you want to setup Oracle Trace File Analyzer (TFA) now ? yes|[no] : 
no

 

2.添加一个不同端口的监听器
在新用户oracle01下添加

[oracle01@localhost admin]$ more listener.ora 
# listener.ora Network Configuration File: /u02/app/oracle/product/12.2.0.1/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

LISTENER12C =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = host11g)(PORT = 1522))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1522))
    )
  )

 

3.修改新数据库的参数local_listener
alter system set local_listener='(ADDRESS=(PROTOCOL=TCP)(HOST=host11g)(PORT=1522))' scope=both;

 

4.查看状态

[oracle01@localhost admin]$ lsnrctl status LISTENER12C
