在安装Oracle数据库的PL/SQL工具时候,电脑名称是重装系统后自动生成的用户名名称,作为程序员,有很强的强迫症,就想利用自己的英文名称作为自己电脑的名称,所以就修改了电脑的名称;结果PL/SQL数据库可视化工具就不能打开了;下面是修改电脑用户名后需要修改Oracle数据库相关数据的步骤:
修改过后出现这样的问题:
Windows不能在本地计算机启动OracleDBConsoleorcl
解决的步骤:
1、开始-》运行cmd

C:\Documents and Settings\xcl>set oracle_sid=orcl
4、再次执行emctl start dbconsole
C:\Documents and Settings\xcl>emctl start dbconsole
