常见监听故障处理方法

1:TNS-12537, TNS-12560, TNS-00507的处理

启动监听报如下错误,一般情况下为/etc/hosts文件中回环地址信息内容误被删除导致。

[oracle@jason admin]$ lsnrctl start

修改/etc/hosts文件内容如下,启动正常。

[root@jason etc]# cat hosts

# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1               jason localhost.localdomain localhost
::1             localhost6.localdomain6 localhost6

2:TNS-12545,TNS-12560,TNS-00515的处理

[oracle@jason admin]$ lsnrctl start

TNSLSNR for Linux: Version 10.2.0.1.0 - Production
System parameter file is /orac/orahome/app/oracle/product/10.2.0/db_1/network/admin/listener.ora
Log messages written to /orac/orahome/app/oracle/product/10.2.0/db_1/network/log/listener.log
Error listening on: (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=jason)(PORT=1521)))
TNS-12545: Connect failed because target host or object does not exist
 TNS-12560: TNS:protocol adapter error
  TNS-00515: Connect failed because target host or object does not exist
   Linux Error: 11: Resource temporarily unavailable


出现以上报错是由于监听的地址里设置为主机名,而/etc/hosts中未对该主机名进行解析,所以导致不能找到目标主机。

处理方法:

(1):将监听地址改为ip地址。

(2):在hosts文件中添加“主机ip   主机名”。

3:TNS-01189报错处理。

故障环境:

    环境为浪潮bcp做的双机,由于双机出现故障,A机获取vip地址但未获取镜像磁

盘,启动数据库到nomount状态。

    B机获取磁盘镜像并成功加载数据库,启动数监听时报如下错误:

    TNS-01189: The listener could not authenticate the user


    查看监听配置内容,监听地址为VIP地址,由于B机未获取到vip,所以监听勿以

为启动远程监听(这块牵扯到监听安全方面知识,详细查看官方资料),所以报TNS-01189错误。

解决方法:根据应用环境,使VIP地址切换到B机。

4: ORA-12547报错处理。

查看$ORAHOME/BIN下oracle可执行文件权限是否为(6751

# ll oracle

-rwsr-s--x 1 oracle oinstall 116208733 2011-06-14 oracle

如果这里不是这样,请使用:

chmod 6751 $ORAHOME/BIN/oracle

进行修改。
