Hi,
whe are running portal unter zope2.7 with one zeo server and six frontend application servers.
I have set up zeo to server two storages
<filestorage main> path $INSTANCE_HOME/var/Data.fs </filestorage>
<minimalstorage temp> envdir $INSTANCE_HOME/var/session </minimalstorage>
temp should provide an shared session. But when is set up the frontends to use temp as /temp_folder, we see many ZODB conflict errors. The performance decreases and PosErrors appear quite often.
BDBMininalStorage is no longer maintained and doesn't do any "conflict resolution".
Why this. I was told some time ago we should use BDBMinimalStorage to fix the conflict problems.
Even though you'll need to pack frequently, you might want to try a FileStorage instead.
There is no difference between BDB Storage and Filestorage regarding the conflicts.
Regardless, using ZEO will presumably always generate more conflict errors than using a "local" ZODB because the commit time is longer, and thus there's a better chance that two threads will be committing at the same time.
The bottom line is that there is no way of getting an shared session running. Why isn´t there an implementation of temporary storage for ZEO I dont care about conflit resolution. Its only session data. I simply need a shared session storage. But as Far as i can see the is no way of doing this. Are we the only site out there running Plone2 (Placeless transaltion Service) at that scale. How do others handle there Session Bye Estartu -------------------------------------------------------------------------- Gerhard Schmidt | Nick : estartu IRC : Estartu | Fischbachweg 3 | | PGP Public Key 86856 Hiltenfingen | estartu@augusta.de | auf Anfrage/ Tel: 08232 77 36 4 | | on request Fax: 08232 77 36 3 | |
