[Zope] DCOracle2 broken due to inability to map library

[Webmaster]

We are trying to implement DCOracle2 (ZOracleDA seemed to require too
many other products to get it to work) and keeps triping up on the
inability to map library libclntsh.so.8.0

Has anyone had success connecting to an Oracle DB from zope? If so how
did *you* do it, and are there any obvious mistakes we are making.
(apart from the obvious one of trying to connect to an Oracle DB in the
first place). Are there any other product we can use?
