各位好!
刚跳到新公司,没有DBA交接,衰!
在熟悉数据库的过程中,遇到同一台小机,不同监听端口,相同实例名字,数据库用户分别不同的问题,请大家帮忙分析分析,这个库要怎么连接。
[root@localhost ~]# cat /etc/redhat-release
CentOS release 6.4 (Final)
[root@localhost ~]# uname -a
Linux localhost.localdomain 2.6.32-358.el6.x86_64 #1 SMP Fri Feb 22 00:31:26 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

监听端口:1521,9521(开发提供的,测试两个端口都可以登录,实例配置均为 orcl ,但是数据库用户等信息不同)
ORCL_139=

在服务器端,只有一个监听listener.ora文件
[root@localhost ~]# find / -name listener.ora

ADR_BASE_LISTENER = /opt/oracle

端口 1521,9521 均有占用信息:
netstat -anp |grep 1521 |more
tcp 0 0 ::ffff:192.168.56.139:1521 ::ffff:11.26.1.16:51648 ESTABLISHED 23352/oracleorcl

现在,我在服务器端,默认监听是 1521。
1:是通过怎么样的设置,才能达到这种效果?
2:要怎么操作,才能连接到 9521的端口? |
