first, the problem leads to: in the x64 environment installation Oracle, the completion of the library, there will be warning pop-up, the following figure. But at the moment everything is working in the Oracle process, so it's not clear what it means to have this warning.
Ii. Solution to the problem:
1, first of all, need to be clear about what is Enterprise Manager.
Oracle Enterprise manager,oracle Enterprise Manager, or OEM, can monitor and manage multiple databases on multiple systems at the same time, as well as monitor management nodes, databases, and listener processes.
2. So closely related to Oracle, we first need to know how to log in with EM to the database we created and manage it.
The default way Oracle provides access to the enterprise Manager dbconsole for the database is this:
First database: http://< machine name or ip>:1158/em
Second database: http://< machine name or ip>:5500/em
Third database: http://< machine name or ip>:5501/em
... Port number and so on.
Please note that the order of the above mentioned databases is arranged according to the order in which you created the database, not in the order of startup.
Of course, the prerequisite for logging on to the EM interface is to start EM first, the correct sequence of boot 10g em is:
Windows: Find a service with a dbconsole name in the service and start it.
Linux classes:
1. Export oracle_sid=< database Instance name >
2. Export oracle_home=< directory name for installing ORACLE database software >
3. $ORACLE _home/bin/emctl start Dbconsole
