本文档介绍了在遇到Can't locate CompEMdbconsole.pm错误时如何设置环境变量和检查$ORACLE_HOMEin目录。同时，针对IP地址变动导致的Oracle Enterprise Manager 11g版本不匹配问题，提供了触发明细和解决方案，包括修改相关文件和拷贝perl模块。

1. Can't locate CompEMdbconsole.pm in @INC造成的问题

Set the environment correctly for the Database ORACLE_HOME:

Unix:

export ORACLE_HOME=
export ORACLE_SID=
export PATH=$ORACLE_HOME/bin:$PATH

$ORACLE_HOME/bin: emctl start dbconsole

Windows:

set ORACLE_HOME=
set ORACLE_SID=
set PATH=$ORACLE_HOME\bin:$PATH

$ORACLE_HOME\bin: emctl start dbconsole

我看了下目录$ORACLE_HOME\bin文件 perl模块没有，可能解压出问题，由于perl是跨平台的语言，直接找个相应的版本复制一下

把comp和db开头的pm复制到$ORACLE_HOME\bin下

2.由于ip地址改动的问题EM报

[oracle@localhost bin]$ emctl status
EM Configuration issue. /opt/oracle/product/11.2.0/db_1/localhost.localdomain_ocmdb not found.

[oracle@localhost bin]$ touch /opt/oracle/product/11.2.0/db_1/localhost.localdomain_ocmdb

启动成功，可是版本竟然是11.2.0.1.0的，数据库版本是11.2.0.3.0，原因是我从11.2.0.1.0版本拷过去的，不影响，只是提示而已
