在DBCA 单实例 创建过程中报错如下

由于我是ASM单实例数据库创建，所以我使用grid用户创建的 listener 结果导致如上报错

在EM创建资料库的时候，需要记录listener的home 目录

对于oracle用户来说，listener的home目录是/u01/app/oracle/product/11.2.0/dbhome_1/network/admin

对于grid用户来说，listener的home目录是/u01/app/11.2.0/grid/network/admin

所以在最后的配置时才会出现如上报错，此时我们只需要将listener关掉，使用oracle用户创建一个listener即可，创建完成后执行

[grid@oel11g admin]$ lsnrctl status

然后执行脚本/u01/app/oracle/product/11.2.0/dbhome_1/bin/emca 重新配置EM

方法如下：

1.   [oracle@oel11g bin]$ emca -deconfig dbcontrol db   --删除dbcontrol配置信息
2.   [oracle@oel11g bin]$ emca -repos drop   ---删除repository
3.   [oracle@oel11g bin]$ emca -config dbcontrol db -repos create   ---重建EM

如果不执行第1、2步操作的话很可能会报如下错误

以上是因为对EM资料库的信息没有删除干净导致的原因。

创建完成后执行
