Bulk Metadata Update using RIDC API!!

Question

Hi,
In my program I have to update bulk content's metadata value. For example I would like to update 'xComments' filed through my RIDC api call in java for 40K contents. In the last run the program was taking huge amount of time(in hours) to update the contents.
Could you please advise me any performence fine tuning or alternate operation to reduce the metadata update time. The java program runs in a single thread. Find the RIDC doc_update code below.
Code:
import oracle.stellent.ridc.*;
import oracle.stellent.ridc.model.*;
import oracle.stellent.ridc.protocol.*;
public class UpdateMetadata {
     private static IdcContext userContext = null;
     static public void main(String args[]) throws Exception {
          System.out.println("RIDC - tests");
          IdcClient idcClient = null;
          try {
               // Create the Manager
          IdcClientManager manager = new IdcClientManager();
               idcClient = manager.createClient("idc://<IPADDRESS>:4444");
               IdcContext userContext = new IdcContext("sysadmin");
               DataBinder binder = idcClient.createBinder();
               binder.putLocal("IdcService", "UPDATE_DOCINFO");
          for(int i=0;i<Resultset.size();i++)
               binder.putLocal("dID", resultset.did);
               binder.putLocal("dDocName", resultset.ContentID[i]);
               binder.putLocal("xComments","****True****");
               ServiceResponse response = idcClient.sendRequest(userContext,binder);
               System.out.println("Processed");
               DataResultSet resultSet = binders.getResultSet ("SearchResults");
               // loop over the results
               for (DataObject dataObject : resultSet.getRows ()) {
                    System.out.println ("Title is: " + dataObject.get ("dDocTitle"));
                    System.out.println ("Author is: " + dataObject.get ("dDocAuthor"));
          } catch (IdcClientException ie) {
               System.out.println("Exception while creating the client" + ie);

Answer 1

The code seems to be incomplete:
- there are some variables like Resultset, resultset that are not initialized in the code (but probably are somewhere else)
- there is a line }*/, but no starting /* (could be corrupted by the editor)
Anyway, if you write that
In the last run the program was taking huge amount of time(in hours) to update the contents. I'd focus first for a question: what has changed? Btw. what is the expected (experienced?) result?
As for the code, it looks OK to me. You could probably throw away everything behind ServiceResponse response = idcClient.sendRequest(userContext,binder); but it seems the second loop is commented out anyway.
To reach better performance, you can certainly try to run the program in several threads - it will require some fine tuning to find out how many threads are optimal. For CHECKIN_NEW, we had the best performance with 3 threads in parallel, but it operated with 100-500kB files, so I'm not sure if these results are relevant also for UPDATE_INFO. I doubt, however, that improvements achieved with parallelism can be higher than let's say 2-3x faster.
