Hi Mike,
From: <Cayanan>, "Michael D (388J)" <[email protected]<mailto:[email protected]>> Reply-To: "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> Date: Thursday, December 13, 2012 10:41 AM To: "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> Subject: Re: Workflow 2 Thanks for the helpful information Chris. This is a good starting point! Woot! Can you help me start documenting this on the Apache OODT wiki? I threw up Brian's Wengine user guide, which is useful in its own right since we still have the branch out there, and some folks using it, but how about we start a new "Workflow 2 Quick Start" page on the wiki and through this and stuff below on it? If I wanted to specify parallel tasks in a workflow, that would mean I'd have to use workflow 2 policy instead of workflow 1 policy, correct? If this isn't true, how does one specify parallel tasks using workflow 1 policy? Yep you would use workflow2 style policy of which there are examples in src/main/resources/wengine in the trunk. Thanks! Cheers, Chris Thanks, Mike From: <Mattmann>, Chris Mattmann <[email protected]<mailto:[email protected]>> Reply-To: "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> Date: Wednesday, December 12, 2012 6:50 PM To: "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> Subject: Re: Workflow 2 Hey Mike, From: <Cayanan>, "Michael D (388J)" <[email protected]<mailto:[email protected]>> Reply-To: "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> Date: Wednesday, December 12, 2012 10:15 AM To: "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> Subject: Workflow 2 Hi all, I would like to start using the latest and greatest Workflow in the trunk. Has anyone been using it lately? That would be me :) I'm trying to figure out which configuration files are needed now in order to run this latest version. Or is it backwards compatible? It's fully back compat. So feel free to point wengine at your existing CAS workflow 1 policy and it should load fine. In 0.3, I know I had to configure a couple of xml files: events.xml, task.xml, conditions.xml. However, in the examples directory, I do see a wengine folder, where it looks like those 3 config files aren't needed anymore? They don't have to be used, but they can be used. If someone can point me to some sample set of files I can use as a reference, that would be awesome! :D Sure, check this out: http://svn.apache.org/repos/asf/oodt/trunk/workflow/src/main/resources/examples/ Those files should work fine. Give it a try. As for your workflow.properties file, it should look like this: # wengine properties # define workflow prioritizer class to use for sorting workflow tasks org.apache.oodt.cas.workflow.wengine.prioritizer=org.apache.oodt.cas.workflow.structs.FILOPrioritySorter org.apache.oodt.cas.workflow.wengine.taskquerier.waitSeconds=2 # the maximum number of threads to be used by the asynchronous engine runner org.apache.oodt.cas.workflow.engine.asynchronous.runner.num.threads=25 You'll need those properties at a minimum. Then, at the top of your file, select: # workflow repository factory workflow.repo.factory = org.apache.oodt.cas.workflow.repository.PackagedWorkflowRepositoryFactory # workflow engine factory workflow.engine.factory = org.apache.oodt.cas.workflow.engine.PrioritizedQueueBasedWorkflowEngineFactory # engine runner factory workflow.wengine.runner.factory=org.apache.oodt.cas.workflow.engine.runner.AsynchronousLocalEngineRunnerFactory Remember for your packaged workflow repo to set: # wengine-style packaged workflow repo properties org.apache.oodt.cas.workflow.wengine.packagedRepo.dir.path = /path/to/wengine/workflow/files And to define your wengine lifecycle: org.apache.oodt.cas.workflow.lifecycle.filePath=/usr/local/workflow/policy/wengine/wengine-lifecycle.xml HTH! Cheers, Chris
