oracle 10g 企业管理器无法打开解决方法

今天发现oracle 10g企业管理器无法打开，于是google，发现问题解决了。本质就是重新配置。步骤如下：

C:\Documents and Settings\Administrator>emctl status dbconsole
Environment variable ORACLE_SID not defined. Please define it.

C:\Documents and Settings\Administrator>set oracle_sid=testdb

Usage ::
emctl config console <fileloc> [<EM loc>]
where <fileloc> contains config entries.
emctl config [agent] addtarget [-f|-force] <fileloc> [<EM loc>]
where <fileloc> contains a definition of target to add,
and where -f or -force allows to overwrite an existing target.
If -f or -force is not specified, existing targets cannot be overwritten.
emctl config [agent] addtargets [-f|-force] <fileloc> [<EM loc>]
where <fileloc> contains a definition of targets to add
and where -f or -force allows to overwrite existing targets.
If -f or -force is not specified, existing targets cannot be overwritten.
emctl config [agent] modifytarget <fileloc> [<EM loc>]
where <fileloc> contains a new definition of target to modify
emctl config [agent] deletetarget <type> <name> [<EM loc>]
where <type>,<name> specify target type and name to delete
emctl config [agent] listtargets [<EM loc>]
lists all targets present in targets.xml
emctl config [agent] listcentralagents [<EM loc>]
lists the central agents this home is associated with
emctl config [agent] addcentralagent <centralAgentHomePath> [<EM loc>]
associates this home with a new central agent
emctl config [agent] removecentralagent <centralAgentHomePath> [<EM loc>]
removes the association of this home with a central agent
emctl config [agent] setcentralagents <centralAgent1> [<centralAgent2> ...]
sets the list of central agents this home is associated with
emctl config agent addTargetsToRepository <uploadFile> <update_on_dup (true |
false)>
uploadFile contains definition for targets
update_on_dup decides whether updating duplicate targets
This function is for central agent

<EM loc> is optional and can be used to operate on a different Oracle Home.

The centralagent commands do not apply in a agent-only home.
