[ZODB-Dev] RelStorage: Error Installing Plone Site on Oracle RAC

[Darryl Dixon - Winterhouse Consulting]

Hi Folks,

We have a Plone (3.3.2) infrastructure currently residing on ZEO (ZODB).
We are looking to swap some of the databases to a RelStorage backed DB
instead (Oracle RAC). We have been running the RelStorage (1.4.1)
connection to the RAC without error for a while now for storing some
metadata and other data structures (general Zope stuff, not Plone
specific). We have added a new schema to our Oracle RAC database and mount
point inside Zope, attempted to add a Plone site, and get the following
error. If everything else remains the same, but the ZODB Mount in the
zope.conf gets pointed back to a regular ZEO/ZODB, it works fine:

2010-12-03T10:31:14 ERROR Zope.SiteErrorLog 1291325474.290.650785606429

Any thoughts on why RelStorage usage might cause this?
