[Zope-dev] Re: Bump up the nr of ZOpe trhreads
- Original Message - From: Chris McDonough [EMAIL PROTECTED] You'll also want to change the number of database connections. If you use FileStorage, put the following in a custom_zodb.py file in your Zope software home or instance home (if you run an instance home setup): 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=25, cache_size=2000) The pool_size parameter is the number of database connections. The number of database connections should always be higher than the number of threads by a few (it doesn't make sense to have fewer database connections than threads). Great, thanks :-) But, am I still limited to max 7 zope threads? I wish to have around 20. About 1/2 to 1 year ago I recall being told that with python z2.py -t nrOfThreads nrOfThreads could be set to whatever but Zope would not use more than 7 in any case. Is this so still? Can it be changed? And is -t a parameter for zserver or for the ZODB?

Apart from the -t option to z2.py (that, afaik, limits me to only 7), what other settings do I need to change to bump up the number of Zope threads to around 20, remember that -t 20 uses 20 times more memory than -t 1 . Might you be better off with a smaller number of threads, and use the memory for a huge cache for oracle queries? both for ZServer and for ZODB Accesses? If i change these settings, which one will allow me to have around 20 threads available to access an external Oracle DB (the zserver or the ZODB)? ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

You can set this to whatever you like, but as I said before it doesn't make sense to have fewer database connections than threads, so they go sort of hand-in-hand. The parameter is the number of ZPublisher worker threads. This is how many threads are hanging around to service requests that come in to ZPublisher (typically via ZServer, but not always). These threads are *related* to the ZODB (as each one typically accesses it), but are not ZODB threads (there is no such thing). - C ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

Re: [Zope-dev] Unit testing on win32 with FAT requires patch to custom_zodb.py,isthis a known issue?
Hello:
I was just curious as to what the status is on this.
I just had to apply the patch to yet another Win2000 computer.
Thanks,

[Zope-dev] Passing a Folder as a Parameter to a Script
Hello Folks,
A fairly straightfoward question. I'm trying to create some scripts that
allow the folder and file structure of the content to control dynamicly
the content of the menus that present said content.
In a directory are folders. These folders are the Menu Headings of the
content.
Beneath each Menu Heading are some links in a submenu determined by
the files within the associated folder.
If I call the submenu script explicitly in the correct context, it
generates the correct content. However the menu items should not be hard
coded so I want to pass the folder to the script which generates the
submenu content. I have it all figured out except the parameter passing.
I have included the relevant part of the Page Template at the bottom.
The script menuWidget looks for folders in the current context. The
script subMenuWidget looks for Page Templates in the current context,
but needs to be modified to accept an ObjectManager object as a
parameter. (the items object from the menu repetition loop)
I've looked around, fidgeted, snooped, and guessed. No luck. I can't
seem to call it correctly. I believe I only need to add a parameter to
the script in the ZMI, and change these lines
div tal:define=submenu here/org/subMenuWidget.py tal:omit-tag=
(from the template)
submenuitems = context.objectValues('Page Template')
(from subMenuWidget.py)
For completeness I will include the code of subMenuWidget, but I doubt
its relevant to this semantic and syntactic question.
Thanks in Advance.
Edward
PS - if anyone has any good ideas on how to sort the collection of
ObjectManager objects based on the numeric content of the isRanked
comment, advice is appreciated.
