Hi,
It seems that lot of system resources are getting consumed in zope because of its transaction log feature. Ff course it has got its utility in undoing some mistakes. Transaction log? Explain what you mean or claim.

What is consuming resources? If you don't need the undo form, just don't use it. Otherwise where should be a performance impact during standard Zope operation. Please explain! -aj On 02.09.09 10:00, Kedar Dash wrote:
Hi
thanks for your response.
I am referring to http://<IP>:<port>/manage_UndoForm . Is there a way where by I can configure zope not to have this logging feature.

The standard Zope installation runs on top of the ZODB FileStorage, which provides this fetaure. The resource consumption (disk space) can be mitigated by packing the storage frequently, which removes the older records. You can run other applications on top of Zope (e.g., using relational data), which won't impact it. There used to be ZODB storaages which were "packless" or which did not support undo: AFAIK, none of them are supported any longer.

How this feature can be disabled in zope.
The standard FileStorage backend for ZODB and Zope is an append-only database. It would not be possible to remove the append-only nature without a complete redesign of FileStorage. I doubt anyone wants to take that on. There are alternatives to FileStorage, however. For example, I've tinkered with a version of RelStorage that does not save any history. It seems to work well, but I haven't released any history-free version yet. Shane
