Oracle Enterprise Manager快速重建

2024-07-10 12:30:48   222人阅读

      我们在使用Oracle时， 可以利用Oracle自带的EM(Enterprise Manager)来更方便的管理我们的数据库。但是有时候我们的em却有时候无法连接，造成这个问题的原因有好多，例如没有正确的配置hostname,或者操作系统的防火墙问题等等。如果出现了问题，我们能否快速的重建em呢？答案是肯定的。我们可以通过Oracle官方文档来参照。但是如果我们对于em里面如此多的配置命令和选项比较头大的时候，你就可以参照此文来重新创建EM。

首先需要设置好环境变量ORACLE_HOSTNAME

export ORACLE_HOSTNAME=testbox.localdomain

然后再执行：

emca -config dbcontrol db -repos recreate

如果这个方法不行的话，你可以手动先drop掉你当前的repo

emca -deconfig dbcontrol db -repos drop

然后再重新创建

emca -config dbcontrol db -repos create

此间过程比较长，大概需要十分钟左右来创建。然后你就可以看到如下提示：
