redhat 10G的listener.ora配置,注意iptable

# listener.ora Network Configuration File: /data/oracle/oracle/oracle/network/admin/listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_NAME = jidb1) #全局名称
(ORACLE_HOME = /DBSoftware/app/oracle/product/10.2.0/db_1)　　　　#环境变量
(SID_NAME = jidb1sid) #数据库SID
)
)

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
)
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 要监听的IP )(PORT = 1521))
)
)
)

监听的关闭与启动命令，在oracle账户下华人成功网:

lsnrctl start /stop

设置临时的默认数据库sid

su - oracle

export Oracle_SID=jidb1sid

然后在 sqlplus jf/1

如登陆系统管理员 sqlplus sys/1 as sysdba

除了设置监听外还要注意linux的防火墙(iptable)

redhat的iptable配置文件

vi /etc/sysconfig/iptable 配置允许1521端口

如果不确定是否是iptable造成不能访问可以使用

service iptables start

将iptable暂时关闭掉
