Argh, I believe this means the book is still out of date on that point. I've never needed to tweak the number of connections, but AFAICT googling for "pool-size" and either "zodb" or "zope.conf" may be helpful. -PW -- Paul Winkler http://www.slinkp.com ___ 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 )
RE: [Zope] custom_zodb.py
Per http://www.plope.com/Books/2_7Edition/MaintainingZope.stx#2-27 , it still says write your own custom_zodb.py . Can you point me to the exact location ?

[Zope] custom_zodb.py
In the Zope Book v2.6, it says : "Each database connection maintains its own cache (see above, "Database Cache"), so bumping the number of connections up increases memory requirements. Only change this setting if you're sure you have the memory to spare. To change this setting, create a file called "custom_zodb.py" in your Zope installation directory. In this file, put the following code:" Am not sure which directory "Zope installation directory" pertains to. Is this the fresh directory from the Zope .tar.gz file ? Or is this the already-installed directory ? Or would it be the instance directory ? If so, which subdirectory do I place custom_zodb.py ?

[DM] because it is *very* confusing to see a specific configuration in the configuration file which is not used (because it is by magic overridden through "custom_zodb") and see information in "Control_Panel" --> "Database management" --> "main" which has nothing to do with what is really in effect. -- Dieter ___ 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 )

You will agree that it is confusing at best to even allow a completely different and totally unmaintained way of configuring these things. zope.conf is the way it should be done, and people who don't do it yet should be reminded to change their config. jens ___ 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 )

[Zope] custom_zodb.py and Control_Panel
Title: custom_zodb.py and Control_Panel
v2.7.4 running on Linux - I'm trying to use this (custom_zodb.py in INSTANCE_HOME)
-
import os
import ZODB.FileStorage
import ZODB.DB
filename = os.path.join(INSTANCE_HOME, 'var', 'Data.fs')
Storage = ZODB.FileStorage.FileStorage(filename)
DB = ZODB.DB(Storage, pool_size=10)
---
When I do it, zope does start up and run, but I get IOError every time I try to look at the "main" storage in Control_Panel->Database:

If I remove the custom_zodb.py file, the problem goes away. Why is the file locked to the ZMI when I use custom_zodb.py?
