1.故障描述
今天有空在Linux上安装了一台Oracle测试服务器，安装完成使用sysdba登陆的时候遇到问题
[oracle@Database ~]$ sqlplus / as sysdba

ERROR:
ORA-12162: TNS:net service name is incorrectly specified
2.故障分析
确认ORACLE_HOME和ORACLE_SID环境变量参数
[oracle@Database ~]$ echo $ORACLE_HOME
/u01/app/oracle/product/11.2.0/dbhome_1
[oracle@Database ~]$ echo $ORACLE_SID
[oracle@Database ~]$
ORACLE_SID无显示
3.故障解决
添加ORACLE_SID参数
[oracle@Database ~]$ export ORACLE_SID=orcl
[oracle@Database ~]$ echo $ORACLE_SID
orcl
测试连接登陆SYSDBA
[oracle@Database ~]$ sqlplus / as sysdba
