ORACLE 问题解决
(1).ORA-12162: TNS:net service name is incorrectly specified
解决方法:1.cd
2.ls -alt
3.vi ./bash_profile 添加如下内容
export ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1
export ORACLE_SID=要设置的SID
(2)ora-01034:oracle not available
ora-27101:shared mermory realm does not exist
解决方法:
Enter user-name: / AS SYSDBA
Connected to an idle instance.
SQL> startup
ORACLE instance started.

(3)ORA-12170 TNS 连接超时
解决方法:
1.ping ip地址 查看网络问题,看能否ping通
2.lsnrctl status lsnrctl是listener-control 监听器的缩写,查看监听的状态
如果未启动,使用lsnrctl start 命令启动
3.cmd-----tnsping ip地址(或者是服务器的实例名SID)如果报“TNS-12535:操作超时”,可能是服务器端防火墙 没有关闭
查看防火墙命令
/etc/init.d/iptables status 会得到一系列信息,说明防火墙开着
Linux 关启防火墙命令
1)重启后永久生效
开启: chkconfig iptables on
关闭: chkconfig iptables off
2)及时生效,重启后失效:
开启:service iptables start
关闭:service iptables stop
(4)ORA-12514: TNS: 监听程序当前无法识别连接描述符中请求的服务
解决方法:
配置文件 tnsnames 中的 SERVICE_NAME 项可能不对,
1) sqlplus 下运行 select instance_name from V$instance; 查看
2) LINUX oracle用户下 echo $ORACLE_SID
(5)bash: sqlplus: command not found 解决方法
环境变量已经配好,但是仍报错:
[oracle@dg1 ~]$ vi .bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs

export PATH
export ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1
export ORACLE_SID=ora64bit
export PATH=$ORACLE_HOME/bin:$PATH
解决方法:
[oracle@dg1 ~]$ sqlplus
bash: sqlplus: command not found
[oracle@dg1 ~]$ su - root

[root@dg1 ~]# ln -s $ORACLE_HOME/bin/sqlplus /usr/bin
