标签：oracle em dbconsole 无法启动 getcwd
之前在自己的测试环境上做了个异机恢复，原来的库上是配置过EM的，但是在恢复的库上去启动EM就报错了，下面看具体解决过程：
PS：原主机名为zlm，恢复出来的主机名为bak
[root@bak ~]# su - oracle

既然提示文件找不到，很显然是因为主机名变更的缘故，那么把名字变一下，用mv命令
[oracle@bak j2ee]$ mv -r OC4J_DBConsole_zlm_ora10g/ OC4J_DBConsole_bak_ora10g/

看来仅仅重新配置一下EM资料库是不行的，需要重建一下（先删除，后创建）
[oracle@bak log]$ emca -repos recreate
shell-init: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory
Error occurred during initialization of VM

该错误表示 getcwd 命令无法定位到当前工作目录。一般来说是因为 cd 到了某个目录之后又rm
了这个目录
这时去执行某些命令就会报 getcwd 错误?，只需要 cd 到任何一个实际存在的目录下在执行命令即可。
出现这种现象的原因还有，当前用户没有当前目录的可执行权限，如没有正确设置ORACLE_SID环境变量，我这里属于这种情况。

可以看到3个successfully，重建后并把em配置也重新刷了一遍

通过重建EM后，就可以用web浏览器登陆EM管理界面了，新的url为：http://bak:1158/em
总结：
遇到各种原因造成的EM无法登陆的问题，通常是因为旧的EM资料库配置有问题，或者是因为改变了主机或IP地址所造成，可以使用emca -repos recreate重建，就能直接解决问题，仅仅通过emca -config dbconsole db来重新配置是不够彻底的，因为还会有之前错误信息的残留，除了这几个命令外，emca还有很多其他参数，可以通过emca --help查看，这里就不列举了。
