[Zope-dev] hanging zeo clients
Hi!
We have one ZEO server that handles 3 FileStorages and 8 ZEO clients
connecting to the ZEO server.
Sometimes a client hangs and does no longer handle incoming connections.
The ZEO server log shows in such a case, that the (hanging) client
initiates a new connection
2006-11-12T10:30:39 INFO ZEO.StorageServer (3958) new connection
('10.x.x.x', 32803): ManagedServerConnection ('10.x.x.x', 32803)
If I'm correct, the next that should happen is a log entry from the
ZEO server that he received a handshake from the client. Something
like
2006-11-12T11:12:46 INFO ZEO.zrpc.Connection(S) (10.x.x.x:36805)
received handshake 'Z303'
This never happens. I have to restart the client.
Has anyone an explanation for the hanging clients?
(We're using Zope-2.8.8, Python-2.4.2)
Markus

Re: [Zope-dev] Please vote about conflict errors logging
1. Do you want these ConflictErrors retried logs to be at level:INFO 2. In addition, please specify if you feel those retriedConflictErrors should have their full traceback logged? no, without traceback 3. Finally, please tell us if the ConflictErrors that *can't* be retried (and are returned to the user as an error, and are alsologged to the error_log) should be additionally explicitely logged tothe event log, and at which level:ERROR ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
[Zope] cutpaste from one mounted storage to another
Hi! Is there a possibility to cutpaste from one mounted storage to another? I have a filestorage Data.fs mounted as / and another filestorage Archive.fs mounted at /site/Archive. When I try to cutpaste an object from e.g. /site/foo/bar to /site/Archive/bar I get an InvalidObjectReference Exception: File /opt/Zope-2.8.1/lib/python/ZODB/Connection.py, line 503, in _commit self._store_objects(ObjectWriter(obj), transaction) File /opt/Zope-2.8.1/lib/python/ZODB/Connection.py, line 525, in _store_objects p = writer.serialize(obj) # This calls __getstate__ of obj File /opt/Zope-2.8.1/lib/python/ZODB/serialize.py, line 330, in serialize return self._dump(meta, obj.__getstate__()) File /opt/Zope-2.8.1/lib/python/ZODB/serialize.py, line 339, in _dump self._p.dump(state) File /opt/Zope-2.8.1/lib/python/ZODB/serialize.py, line 281, in persistent_id raise InvalidObjectReference( InvalidObjectReference: Attempt to store an object from a foreign database connection Am I doing something wrong or is this simply not possibly resp. is there a workaround to do a cutpaste between storage boundaries?

[Zope] large installations and conflict errors
Hi! We run a self developed zope product originally based on cmf but highly customized and extended. Our Data.fs now has grown to a (packed) size of 25GB and we are running more and more into performance troubles (mostly due to a lot of conflict errors). Our users make a lot of updates, i.e. we have lots of write operations. Currently we think that our bottle neck is the 'portal_catalog' and I'm working on splitting it up into multiple ZCatalogs. So far our story, but what I really wonder is, if there's anyone out there who has a similar large installation. Please let me know how large your zope instance is and what you have done to increase your (write) performance. Also any ideas that may help us are welcome. Additional info: 4 ZEO clients, 1 ZEO server (all machines have dual P4 and 3-4GB ram), Zope-2.8.0 Thanks, Markus ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
