Oracle Enterprise Manager Grid Control Installation

Oracle Enterprise Manager 10.2.0.1.1 on Oracle Enterprise Linux 5 Update 4 with Oracle 11.1.0.6 as the OMS repository.

I ran into a problem starting the HTTP_Server via the opmnctl startall command.

[oracle@ovmm lib]$ opmnctl status

Performing the following link solved the problem.
