Introduction
This page is intended to provide a guide to quickly start using the Workflow2
Getting Started
To start using the Workflow2, do the following:
Modify workflow.properties
Verify that the workflow.properties file has the following:
| Code Block |
|---|
# 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 the following:
| Code Block |
|---|
# 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:
| Code Block |
|---|
# 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:
| Code Block |
|---|
org.apache.oodt.cas.workflow.lifecycle.filePath=/usr/local/workflow/policy/wengine/wengine-lifecycle.xml |
