[Zope-dev] ZEO on NT? update
Hi, I can see now that the problem is not per Data.fs but per object. The problem isnt that 2nd Client to run cant write do Data.fs, I found that its a per object conflict and not Data.fs, both clients can write to the ZSS but once client B writes to object X, Client A will never see the changes neither change the object X, but is capable of changing other objects. Objects changed buy Client B become "locked" for client A and viceversa. Anyone testing ZEO?

[Zope] Fwd: Re: [Zope-dev] ZEO on NT? update
From: "julio dinis" [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: Re: [Zope-dev] ZEO on NT? update Date: Thu, 22 Jun 2000 14:05:07 PDT Ok. :-) Continuing with the ZODB.POSException.Conflit... Now I know the problem with Zeo on NT is with the ClientStorage and not with the ServerStorage. You ask why? Because Ive tested different setup to come to this conclusion. ZSS - Zeo Storage Server ZCS - Zeo Client Storage 1- First setup: Machine 1: Running ZSS on NT Machine 2: Runninc ZCS on NT Machine 3: Running ZCS on NT Conclusion: with this setup clients ARE NOT able to view/write changes to objects changed by other clients. 2- Second Setup: Machine 1: Running ZSS on Linux Machine 2: Runninc ZCS on NT Machine 3: Running ZCS on NT Conclusion: with this setup clients ARE NOT able to view/write changes to objects changed by other clients. 3- third Setup: Machine 1: Running ZSS on NT Machine 2: Runninc ZCS on Linux Machine 3: Running ZCS on Linux Conclusion: with this setup clients ARE able to view/write changes to objects changed by other clients. 4- Fourth Setup: Machine 1: Running ZSS on NT Machine 2: Runninc ZCS on Linux Machine 3: Running ZCS on Linux Machine 4: Running ZCS on NT Machine 5: Running ZCS on NT Conclusion: with this setup ALL LINUX clients ARE able to view/write changes to objects changed by other clients. All NT clients ARE NOT able to view/write objects changed by other clients. NT clients can view/write objects that have never been changed. But cant viewchanges/change objects changed by other clients. However linux clients can viewchanges/change objects changed by other NT and Linux clients. So my conclusion is that there is a problem with Zeo Clients on NT. And I guess is related with the invalidator, the NT clients cant see changes others do to objects, or something is just a guess. I'm using cPickle.pyd which is cPickle.so on Linux. Maybe there is a diference with this shared object from Linux to Nt. I'm using the win32 version of Zope2.2.0b1, and ZEO-0.2.

[Zope] zodbc performance question
Hi all, Using zodbc, supose we have the following situation. One zodbc_database_connection and lots of zsql methods. Can we say that creating more zodbc_database_connection(with a system dsn for each one, but all pointing to the same database) and thus distribute the zsql methods avoiding to all use the same zodbc_connection, will increase performance. Dont tell me I have to test it, I will but some thougts here will help.

After some time of heavy use of the site the zserver goes zombie, and even restarting will put zope automatically zombie, never more. If I remove the system dsn I use with zodbc and restart zope, then zope runs like a ferrari. I than create again the odbc system dsn and everything is back again. But some time after the zombie arise from the grave :-( I'm looking at logs. Anyone with this problem?
