This is so weird! I'm completely new to Oracle; so this might be a stupid question.
Right after installing the Oracle 10, I was able to connect to the Enterprise Manager. However, after I shut down the computer and connect to it again, it kept giving me an error message "Can't not connect".
I did some researches and found out that it might be because my computer has multiple IP addresses; or the Environment Variables are not defined...However, I've tried everything and it's still NOT working for me so far
Please help!!!!!!!
Thank you

Please read & follow Posting Guideline as stated above

Enterprise Manager is not required to use or access Oracle RDBMS.

Those who live by the GUI, die by the GUI.

hmm, I'm new to this forum. But after reading the guilines, I still couldn't find anything wrong with my post.
In addition, I don't have a strong background in network and system. I'm just following along a video training course for Oracle 10g; and learning EM is HUGE component of the course. So I really don't know what to do.

I know it's a huge favor to ask. But if you can show me where I went wrong, I will greatly appreciate

check your shared pool size and the SGA SETTING.
According to my experience, the problem may be caused by the small memory size on your computer. Oracle highly rely on RAM of the computer.To make it run better performance, increase your memory size. Cool

Since this is a DHCP computer, first check the hosts file (C:\WINDOWS\system32\drivers\etc\hosts) and verify it has the following entry:

127.0.0.1        localhost          <hostname.domainname>       <hostname>

Then perform the following at a command prompt:

C:\> set ORACLE_HOSTNAME=<hostname>
C:\> set ORACLE_HOME=<oracle_home_directory>
C:\> set ORACLE_SID=<oracle_sid>
C:\> cd %ORACLE_HOME%\bin
C:\> emctl start dbconsole

Without knowing the state of your current configuration, it probably wouldn't hurt to run the following prior to doing any of the above.

C:\> set ORACLE_HOME=<oracle_home_directory>
C:\> set ORACLE_SID=<oracle_sid>
C:\> cd %ORACLE_HOME%\bin
C:\> emca -config dbcontrol db -repos recreate

To prevent future startup issues, you may want to set ORACLE_HOSTNAME as a system environment variable.

Check Installing Oracle Database on DHCP Computers for any additional info.
