Just a heads up to anyone installing Linux OEM Grid Control 10.2.0.1.0
If you are doing a full install, the "product specific prerequisite checks" page will show an error on the following packages even if you have them installed.
Note that the installation works fine if you ignore the "missing" prerequisites. I believe the check itself is flawed. The openmotif check should be openmotif21-**** (extra hyphen incorrect in check - the old install was openmotif, now openmotif21), the libstdc++ needs a hypen added before the devel, and the compat-libstdc++ has yet another issue.
This is something the developers at oracle will have to fix.
