I installed relstorage using the instructions for easy_setup, i.e. 'easy_install RelStorage'. I realized as I read through more of the instructions that this likely put the relstorage modules in my python home rather than in my zope software home. I don't know if this would have caused the error I am seeing. However, after reading more through the instructions, and watching easy_install do its magic, I reached a point where I make a new zope instance, then when in to that instance home and modified the zope.conf to use relstorage instead of filestorage, I was ready to start my new instance. I was disappointed to have a traceback just running zopectl. I ran $INSTANCE_HOME/bin/zopectl and got the following traceback: Traceback (most recent call last): File "/servers/webenv1/lib/python/Zope2/Startup/zopectl.py", line 329, in ? main() File "/servers/webenv1/lib/python/Zope2/Startup/zopectl.py", line 287, in main options.realize(args) File "/servers/webenv1/lib/python/Zope2/Startup/zopectl.py", line 95, in realize ZDOptions.realize(self, *args, **kw) File "/servers/webenv1/lib/python2.4/site-packages/zdaemon-2.0.2-py2.4.egg/zdaemon/zdoptions.py", line 279, in realize self.load_schema() File "/servers/webenv1/lib/python2.4/site-packages/zdaemon-2.0.2-py2.4.egg/zdaemon/zdoptions.py", line 327, in load_schema self.schema = ZConfig.loadSchema(self.schemafile) File "/servers/webenv1/lib/python2.4/site-packages/ZConfig-2.5.1-py2.4.egg/ZConfig/loader.py", line 32, in loadSchema return SchemaLoader().loadURL(url) File "/servers/webenv1/lib/python2.4/site-packages/ZConfig-2.5.1-py2.4.egg/ZConfig/loader.py", line 66, in loadURL return self.loadResource(r) File "/servers/webenv1/lib/python2.4/site-packages/ZConfig-2.5.1-py2.4.egg/ZConfig/loader.py", line 187, in loadResource schema = ZConfig.schema.parseResource(resource, self) File "/servers/webenv1/lib/python2.4/site-packages/ZConfig-2.5.1-py2.4.egg/ZConfig/schema.py", line 27, in parseResource xml.sax.parse(resource.file, parser) File "/servers/webenv1//lib/python2.4/xml/sax/__init__.py", line 33, in parse parser.parse(source) File "/servers/webenv1//lib/python2.4/xml/sax/expatreader.py", line 107, in parse xmlreader.IncrementalParser.parse(self, source) File "/servers/webenv1//lib/python2.4/xml/sax/xmlreader.py", line 123, in parse self.feed(buffer) File "/servers/webenv1//lib/python2.4/xml/sax/expatreader.py", line 207, in feed self._parser.Parse(data, isFinal) File "/servers/webenv1//lib/python2.4/xml/sax/expatreader.py", line 300, in start_element self._cont_handler.startElement(name, AttributesImpl(attrs)) File "/servers/webenv1/lib/python2.4/site-packages/ZConfig-2.5.1-py2.4.egg/ZConfig/schema.py", line 99, in startElement getattr(self, "start_" + name)(attrs) File "/servers/webenv1/lib/python2.4/site-packages/ZConfig-2.5.1-py2.4.egg/ZConfig/schema.py", line 475, in start_schema keytype, valuetype, datatype = self.get_sect_typeinfo(attrs) File "/servers/webenv1/lib/python2.4/site-packages/ZConfig-2.5.1-py2.4.egg/ZConfig/schema.py", line 201, in get_sect_typeinfo datatype = self.get_datatype(attrs, "datatype", "null", base) File "/servers/webenv1/lib/python2.4/site-packages/ZConfig-2.5.1-py2.4.egg/ZConfig/schema.py", line 194, in get_datatype return self._registry.get(dtname) File "/servers/webenv1/lib/python2.4/site-packages/ZConfig-2.5.1-py2.4.egg/ZConfig/datatypes.py", line 398, in get t = self.search(name) File "/servers/webenv1/lib/python2.4/site-packages/ZConfig-2.5.1-py2.4.egg/ZConfig/datatypes.py", line 423, in search package = __import__(n, g, g, component) File "/servers/webenv1/lib/python/Zope2/Startup/datatypes.py", line 21, in ?

Furthermore, what I couldn't discern from the install instructions for relstorage was configuration for postgresql. Since the instructions were silent, I assumed I at least needed a pg user for zope to connect as, and a database to contain the zodb. So I created these in pg so the dsn in zope.conf would at least have something valid to connect to. Any adivce? I think I will need to back out of what easy_install did to my pythonhome -- is there an easy way to undo what easy_install did ? -- David Bear College of Public Programs at ASU 602-464-0424
