Connecting to Oracle Enterprise Manager

Tuesday, March 12, 2013 6:39 pm

I don’t usually install Oracle that often, but when I do it’s usually a successful install without too much fuss. Well, lately I’ve noticed I can’t get Enterprise Manager up in Internet Explorer.

Long story short not being able to view the Enterprise Manager is caused by a certificate with a key length of less than 1024 bits according to Microsoft: http://support.microsoft.com/kb/2661254

To fix:

open a command prompt

certutil -setreg chain\EnableWeakSignatureFlags 8

restart CertSvc

My biggest tip is to first unzip each zip file to the same directory. Otherwise you are guaranteed to get errors.

You may still get errors, but if you are trying to install each zip file separately then forget ‘bout it.

Converting Folder To ISO

A VMware Virtual Machine can connect to ISO files locally. However, not every file that needs to be uploaded to the VM is in an ISO format.

So, to solve this problem I have downloaded Folder2ISO. It does this one task and does it very well for FREE!
