Using DFS For Content Extract

For a customer we need to migrate contents out of Documentum to a new repository. I was looking at using DFS to develop an 'extraction' tool which will take various parameters including selection criteria, query the content and then export the content to the local file system and create a CSV file of some of the properties and also include the file path to the local file.

I have used some sample DFS code to develop a simple test module that extracts content from the system however the file exported via base64 or MTOM has a random generated name and goes to a predefined location. Is there anyway when doing the getcontent to set the file name and export location?

Using UCF you get the Documentum object name but the export location is set in the UCF

Thanks in Advance

IDfExportOperation exportOper = clientX.getExportOperation();

exportOper.setDestinationDirectory("c:\\Temp"); //hard coded the folder in the local file system

IDfDocument doc = (IDfDocument) idfSession.getObject(objId);

IDfExportNode expNode = (IDfExportNode) exportOper.add(doc);

exportOper.execute();

Is this not DFC code, I am using DFS.

Take a look at the ContentTransferProfile class. This has options to specify the destination directory and can be added to the get() call.

Andy, I have had a look and can't see any obvious set.... statements that allow setting of destination folders in the ContentTransferProfile class. Can set the Tranfer Modes, Geo Location etc. but nothing about destination. Can you expand on what you mean. Thanks

It is available in DFS 6.7SP1. Here is a sample code I ran several days ago.

public void DownloadUcfContentWithLocaiton()

{

IServiceContext serviceContext = getServiceContext("core");

IObjectService objectService = ServiceFactory.Instance.GetRemoteService<IObjectService>( serviceContext, "core", "url" );

ContentTransferProfile ctp = new ContentTransferProfile();

ctp.TransferMode = ContentTransferMode.UCF;

OperationOptions options = new OperationOptions(null, ctp);

DataPackage package = new DataPackage();

DataObject ucfDocument = new DataObject(new ObjectIdentity(getDefaultRepository()), "dm_document");

ucfDocument.Properties.Set("object_name", "testDoc_" + System.DateTime.Now.Millisecond);

ucfDocument.Contents.Add(new BinaryContent(new byte[1000], "zip", 0, "", RenditionType.PRIMARY));

package.AddDataObject(ucfDocument);

DataPackage result = objectService.Create(package, options);

ObjectIdentity docId = result.DataObjects[0].Identity;

ContentProfile cp = new ContentProfile(FormatFilter.ANY, "", PageFilter.ANY, 0, PageModifierFilter.ANY, "");

ctp = new ContentTransferProfile();

ctp.TransferMode = ContentTransferMode.UCF;

// set location

ctp.DestinationDirectory = "C:\\dfs_tmp\\fone";

// set Content RegistryOption if you want to download the same content multi-times, with diff locations later

ctp.ContentRegistryOption = ContentRegistryOption.UNREGISTERED;

options = new OperationOptions(null, ctp, cp);

DataPackage download1 = objectService.Get(new ObjectIdentitySet(docId), options);

string dpath1 = download1.DataObjects[0].Contents[0].GetAsFile().FullName;

Console.WriteLine("Download 1 to path: " + dpath1);

ctp = new ContentTransferProfile();

ctp.TransferMode = ContentTransferMode.UCF;

// set location

ctp.DestinationDirectory = "C:\\dfs_tmp\\ftwo";

// set Content RegistryOption if you want to download the same content multi-times, with diff locations later

ctp.ContentRegistryOption = ContentRegistryOption.UNREGISTERED;

options = new OperationOptions(null, ctp, cp);

DataPackage download2 = objectService.Get(new ObjectIdentitySet(docId), options);

string dpath2 = download2.DataObjects[0].Contents[0].GetAsFile().FullName;

Console.WriteLine("Download 2 to path: " + dpath2);

}

You will find equivilant class in Java side.

William, thanks for this, it looks like a new option in DFS6.7 but we are on 6.6 and there is no .DestinationDirectory option in the ContentTransferProfile.

Hi William,

I have tried the same and the document is getting exported in the Temp only. Please advice.

Below is my code

ContentTransferProfile transferProfile = new ContentTransferProfile();transferProfile.setTransferMode(ContentTransferMode.UCF);transferProfile.setDestinationDirectory("C:\\EXPORTED");transferProfile.setContentRegistryOption(ContentRegistryOption.UNREGISTERED);baseServ.getServiceContext().setProfile(transferProfile);  ContentProfile contentProfile = new ContentProfile();contentProfile.setFormatFilter(FormatFilter.ANY);contentProfile.setPageFilter(PageFilter.ANY);  OperationOptions operationOptions = new OperationOptions();operationOptions.setContentProfile(contentProfile);operationOptions.setProfile(contentProfile);  ObjectId objId = new ObjectId();objId.setId(docID);  ObjectIdentity objIdentity = new ObjectIdentity(objId, baseServ.getDefaultRepositoryName());  ObjectIdentitySet objectIdSet = new ObjectIdentitySet();List<ObjectIdentity> objIdList = objectIdSet.getIdentities();objIdList.add(objIdentity);  DataPackage dataPackage = objService.get(objectIdSet, operationOptions);  String path = dataPackage.getDataObjects().get(0).getContents().get(0).getAsFile().getAbsolutePath();System.out.println(path);

The Result is

C:\DOCUME~1\LTAVEN~1\LOCALS~1\Temp\dfs-2031651637358716698.tmp

Thanks

Hi Arun,

Were you able to solve this issue?

Is there any option to set destination directory when other transfer modes are used like MTOM/BASE64 ?

Thanks.
