I just started working with Oracle's products, and I downloaded the "Developer Day" VM from the following link:
http://www.oracle.com/technetwork/database/enterprise-edition/databaseappdev-vm-161299.html
The VM boots up fine. Then, I proceeded to install the Enterprise Manager, from the following link:
http://www.oracle.com/technetwork/oem/grid-control/downloads/linuxx8664soft-085949.html
It was only missing one prerequisite (glibc-devel.i686), which installed without an issue. The problem I have is when I get to the page which asks for the host… by default, it says "localhost," but the setup doesn't like this, and doesn't let me proceed.
Changing it to another irrelevant value doesn't work.
Sorry if this is on the wrong "stack," I assumed that dba would be the best.
