After installing OSB and OEPE (oepe-helios-all-in-one-18.104.22.168.1.201010012100-linux-gtk-x86_64) for Windows 7, I couldn’t see OSB perspective at all in the Eclipse.

Also, make sure that location of weblogic home, osb home and harvester home are updated in eclipse.ini, otherwise one will face issues while creating/opening a OSB Project.
It looks something like this.
