I have two Xron issues that I am seeking assistance with: 1. I am getting the following error when the email_reminder_job gets triggered by the Xron scheduler. I also included a thread with Loren for additional context below the events.log contents as well. Anyone have ideas on what I am doing wrong? The event is scheduled for 5:30 AM EST, 10:30 AM GMT. It looks like it tried to run but got a bci.NotAvailable with a connection refused error. I have the admin folder secured but set the job up with manager, owner, and authenticated proxy rights. I also made the security rights not be acquired, but allowed all rights to the manager, owner, and authenticated users. After the job gets triggered and fails, it says it fails to disarm the event but the event disappears when I click on the schedule object in the ZMI after the job fails. 2. I recatalogged this morning at 5:56 AM which causes a conflict error and the dispatcher thread to die. Not sure what the conflict is unless it relates to the fact that I have another folder (http://www.iresolve.com:8080/iResolve-tim/admin/email_reminder_job) an XronDTMLMethod object with the same name. The second one is for testing purposes and is currently turned off. I renamed the second one and recatalogged again with the same error. I am using ZEO if that matters.

From: Loren Stafford Sent: Monday, February 04, 2002 12:47 PM To: Tim Owen [mailto:timowen@voyager.net] Subject: Re: Xron Question It should not be difficult to manually create your Xron DTML Method on the production server (carefully, in a version), thereby ruling out problems in zsysc'ing. A copyied Xron DTML Method won't get put in the schedule, because cataloging only occurrs when the method is created or updated. You can get it in the schedule by editing it's trigger time in the XMI. You don't actually have to change it, just get Zope to think you changed it. 2002-02-03T16:16:33 PROBLEM(100) Products.Xron.Loggerr Trigger event: http://www.iresolve.com:8080/iResolve-tim/admin/email_reminder_job Trigger time: 2002/02/03 05:30:00 US/Eastern Failed to trigger event.

It indicates that the socket that Client.py uses to fire a scheduled method is not working. That would be a system-depended problem. I would try: 1) tracing with PDB, starting with the dispatcher and following it into client.py, to see if there's any obvious reason the connection is not working. You can uncomment relevant trace statements in Xron code. 2) making a little Client.py application to try to isolate that problem. There's a How-To on that subject somewhere on www.zope.org. That may be the cause of the errors that show later in the log. In any case, Xron won't work if Client.py doesn't work. Client.py is a standard part of Zope that Xron calls to simulate a client request for the Xron DTML Method. There used to be a problem using it with port designators in the URL, but that problem was fixed in an earlier version of Zope. Still, I haven't upgraded to 2.4.3, so I can't testify that Xron works there. You should copy these messages to the zope@zope.org list. Maybe somebody there has prior knowledge of the problem. But no HTML-encoded messages are allowed there. I'll leave that up to you. -- Loren -----Original Message----- From: Tim Owen [mailto:timowen@voyager.net] Sent: Monday, February 04, 2002 2:35 AM To: Loren Stafford Subject: Re: Xron Question I think this is either a permissions error or an error due to copying the XronDTMLMethod from my development server to the production server. I used Zsyncer to move it to the production server then copied to the production folder. The reference to D:\Program Files\iResolve\lib\python\Products\Xron\Dispatcher.py and other Python files on the D: drive refers to my development Windows drive and directory. I deploy on an iMeme hosted server running FreeBSD. The iResolve-tim folder is a test folder on the production server. The production folder is iResolve. In the scheduler it actually only finds and catalogs the copy in the production admin folder not the test folder. Should I recreate the scheduled job in the production folder? Here is the error I get after successfully creating the new schedule: ------ 2002-02-03T16:16:33 PROBLEM(100) Products.Xron.Loggerr Trigger event: http://www.iresolve.com:8080/iResolve-tim/admin/email_reminder_job Trigger time: 2002/02/03 05:30:00 US/Eastern Failed to trigger event.
