Instructions for Regular Workflow Use:
- Download the attached .ZIP file below to your computer. *Remember the location of the saved file on your computer.
- Unzip the file on your computer. Should end up with a .WFD file.
- Log in to UCS Director as a user that has "system-admin" privileges.
- Navigate to "Policies-->Orchestration" and click on "Import".
- Click "Browse" and navigate to the location on your computer where the .WFD file resides. Choose the .WFD file and click "Open".
- Click "Upload" and then "OK" once the file upload is completed. Then click "Next".
- Click the "Select" button next to "Import Workflows". Click the "Check All" button to check all checkboxes and then the "Select" button.
- Click "Submit".
- A new folder should appear in "Policies-->Orchestration" that contains the imported workflow. You will now need to update the included tasks with information about the specific environment.
Inspired by work from Tejeswar Sahu and Saranyasree Vadivel
This example will read from a CSV file located on UCSD and read in values and then register a new LOV variable in the system.
Every time this workflow is executed it will read the CSV file and update/change/create the LOV variable.
Examples of the CSV file being updated on UCSD:
Original List:
The CSV file on UCSD was updated (new States were added):
The the CSV file was partially deleted and updated:
The workflow in 2 custom steps.
Step 1 Read the file and assemble a variable
Step 2 Create the LOV variable
Global Workflow Input:
Currently coded with cdv file in /tmp and called States.csv
The LOV variable created is called LOVStates
The code / custom task behind Step 1:
1 Input, the file name and path
2 Output, the variable with the assembled string (format a=1,b=2,c=3)

var filenamewithpath = input.FileNameWithPath ;
var br = new BufferedReader(new FileReader(filenamewithpath));
var tokens;
var UCSDLoopCounter = new ArrayList();
while(true){
var line = br.readLine();
if(line == null)break;
logger.addInfo("Line" + line);
tokens = line.split(",");
if(tokens != null && tokens.length > 0){
UCSDLoopCounter.add(tokens);
}
}
br.close();
logger.addInfo("UCSDLoopCounter");
var ListSize = UCSDLoopCounter.size();
var details = UCSDLoopCounter.iterator();
var sum = "";
while(details.hasNext()){
//dont want a comma at the end of the string
if (sum != "") {
sum = sum + "," ;
}
var arr = details.next();
logger.addInfo("A0 : "+arr[0]);
logger.addInfo("A1 : "+arr[1]);
logger.addInfo("-------------------------------------");
logger.addInfo("");
var sum = sum + arr[0] + "=" + arr[1] ;
logger.addInfo("Sum : " + sum);
}
output.LOVinputString = sum;
The code behind the registration of the new LOV varaibel
1 Input, the assembled string
2 Inout, the name of the to be registered LOV varaible

lovValue = lovPair.split("=")[1];
formlov = new FormLOVPair(lovLabel,lovValue);
formlovarr[count] = formlov;
}
return formlovarr;
}
createLOV()
Adendum:
Inconsistent situation:
Suppose for the first time I created a lov taking the values from the csv file(say computer=1,phone=2).
Then I updated the lov from the GUI(say after updating ,lov contains computer=1,phone=2,Tv=3).
Again I updated the lov from the task taking the values from the csv file(say computer=1,phone=2,camera=3,watch=4).
As a result what we have updated the lov from the GUI will be lost(Tv=3).
So either we have to update the lov from the task always or from the GUI always.Updating the lov from both ways(task and GUI) might lead to data corruption.
