Re: [MarkLogic Dev General] trigger not getting invoked in a clustered environment
Hi Danny, Thanks once again. I'm not using any content processing framework. Its just an xquery. I don't have the luxury of adding nodes. Any ways it isn't throwing up any errors in the logs that is what is keeping me guessing.I will let you know if I find something interesting!

Re: [MarkLogic Dev General] trigger not getting invoked in a clustered environment
Here are a few other debugging ideas: * In your trigger module, put some xdmp:log statements, logging the URI of the document being modified, for example (you can use the external variable trgr:uri): http://docs.marklogic.com/4.2doc/docapp.xqy#display.xqy?fname=http://pubs/4.2doc/xml/dev_guide/triggers.xml%2355340 * try creating a hello world trigger, just to make sure you have the mechanics correct. * make sure your log level is at least at debug * make sure the task server is set to log uncaught exceptions * try creating a simple cpf pipeline with a hello world trigger--it will do a lot more logging of problems then a straight trigger. * make sure your trigger is the right data event for what you are doing. You might need to create 2 triggers, 1 for modify and one for create that point to the same action (in case you want the same action when a document is created and when it is updated). * if you find yourself creating a framework to manage your triggers, consider using CPF, as that is what it does, and that can be quite complex to write yourself, especially for post-commit triggers. Triggers can be tricky to debug because the actions run in the task server, but with a little persistence, you can usually figure out what is going on. -Danny From: general-boun...@developer.marklogic.com [general-boun...@developer.marklogic.com] On Behalf Of Raghu [raghupathy.visweswa...@gmail.com] Sent: Sunday, September 18, 2011 11:04 AM To: General MarkLogic Developer Discussion Subject: Re: [MarkLogic Dev General] trigger not getting invoked in a clustered environment Hi Danny, Thanks once again.
