Verifying the Installation
The best way to properly verify your caGrid Taverna workflow service installation is to execute a workflow. Use the steps that follow to run our provided sample test workflow.
- Download the Taverna test file. This file is available at: http://wiki.cagrid.org/download/attachments/4489328/HelloWorld.t2flow
. - Change target directory to Globus using the following command:
cd $GLOBUS_LOCATION/bin
- Run the taverna-client against the appropriate caGrid service. If you have deployed your own Taverna service, use the endpoint of your service as the <url>. If you are validating against a service deployed by caGrid, each of the available services is listed below, followed by the necessary command to run the taverna-client.
QA: https://cagrid-taverna-wf-qa.nci.nih.gov:8443/wsrf/services/cagrid/TavernaWorkflowService
Stage: https://cagrid-taverna-wf-stage.nci.nih.gov:8443/wsrf/services/cagrid/TavernaWorkflowService
Prod: https://cagrid-taverna-wf.nci.nih.gov:8443/wsrf/services/cagrid/TavernaWorkflowService
Training: https://workflow-scufl.training.cagrid.org:8443/wsrf/services/cagrid/TavernaWorkflowService
The command necessary to run the taverna-client is as follows:
%> taverna-client -url <url of the service> -scuflDoc <workflow file>
Verify Test Success by watching the output, which should identify the four necessary steps. The command window should show the following tasks being executed:
./taverna-client -url https://cabig-workflow.ci.uchicago.edu:5005/wsrf/services/cagrid/TavernaWorkflowService -scuflDoc ~/execution-example-maven/workflows/helloworld.t2flow
Running the Grid Service Client
OS: Mac OS X
CWD: /local/home/tomcat5/ws-core-4.0.3/bin
1. Running createWorkflow ..
Created a resource with EPR ..
Writing EPR to file ..
/local/home/tomcat5/ws-core-4.0.3/bin/Test.epr
2. Now starting the workflow ..
Reading EPR from file ..
/local/home/tomcat5/ws-core-4.0.3/bin/Test.epr
Workflow Active, still running.
3. Checking the status of the workflow..
Workflow execution is either pending or active.
== NOTE: If this is your first workflow submission to the workflow service,
== it will take longer for your workflow to complete, as it performs a
== one-time download of all the required artifacts (approximately 10-15
== mins depending on your network speed).
== Subsequent workflow submissions will take less time.
4. Getting back the output file..
Output file 0 : /local/home/tomcat5/ws-core-4.0.3/bin/Test-output-0.xml
Congratulations! If the validation is successful, you have installed and deployed a caGrid Taverna workflow service.
