Oracle 11g Enterprise Manager cannot connect to a DB instance

Learn to use an OEM today

The result is two questions!

The first question: Where should I open an OEM?

Solution: Find a half-day, only to know that only using IE can open the OEM,

The URL used is:https://localhost:1158/em/

OK, when you open this URL, you have a second problem: Web Tip "Unable to connect to DB instance"

Also find a half-day, online does have a lot of netizens have given the solution, but to me here always hint dbhome_1 in some files can not backup!

Solution: According to the answer on the network, all is to use the CMD command line to operate, and I just through the "run" open cmd, seemingly insufficient authority, no way to complete the user-given solution, so I through the administrator to open the CMD, the results of his normal execution. \ (^o^)/

It took a couple of hours, but it was fun, and it's called contentment.
