问题描述：

我正在尝试从我的UNIX计算机连接到oracle数据库。我是脚本编写新手。我知道如何浏览unix并编写基本脚本（read / display）并使用bash命令执行它们。我也知道如何在Unix（用户和系统）中查看变量。你能告诉我我需要做些什么来连接到Oracle数据库吗？我如何使用sqlplus命令？

I am trying to connect to an oracle database from my unix machine. I am new to script writing in general. I know how to browse round unix and have written basic scripts ( read / display ) and execute them with bash command. Also I know how to view the variables in unix ( user and system). Could you tell me what i need to do to connect to an oracle database? do I use the sqlplus command? are there any variables I have to set before that?

当然，是的，您需要使用SQL * Plus。但是，在此之前，您需要确定几件事：

Well, yes of course, you need to use SQL*Plus. However, before that, you need to make sure of few things:

export ORACLE_HOME变量

例如，

export ORACLE_HOME=/u01/app/oracle/product/11.2.0

导出路径变量

例如

export PATH=$PATH:$ORACLE_HOME/bin

export SID

例如，

export ORACLE_SID="your database service name"

确保您正确配置了 tnsnames.ora

确保您具有监听器正常运行并正在侦听正确的端口。

Make sure you have the tnsnames.ora configured properly
Make sure you have the listener up and running and is listening to the correct port.

您应该能够以以下方式连接到数据库：

You should be able to connect to the database as:

sqlplus username/password@sid
