  The COMPASS experiment at CERN SPS completed its data taking with hadron
beams (p, \pi, K) in the years 2008 and 2009 by collecting a large set of data
using different targets (H2, Pb, Ni, W). These data are dedicated to hadron
spectroscopy, where the focus is directed to the search for exotic bound states
of quarks and gluons (hybrids, glueballs). The production of such states is
known to be favoured in glue-rich environments, e.g. so-called OZI-forbidden
processes. The OZI rule postulates that processes with disconnected quark line
diagrams are forbidden. On the one hand, the study of the degree of OZI
violation in vector meson production yields the possibility to learn more about
the involved production mechanisms. On the other hand it helps to understand
the nucleon's structure itself. Contrary to former experiments, the large data
sample allows for detailed studies in respect to Feynman's variable xF. We
present results from the ongoing analysis on the comparison of \omega and \phi
vector mesons production in pp->p(\omega/\phi)p, where the possibility of
measuring the spin alignment of both vector mesons at the same time makes
COMPASS unique.
