Hi Chris,

 

Is there a pre-release of 2.1 available for testing?

 

Thanks,

 

Lawrence

I tested a loader group twice in 2.1 with 3 members by identifier, and it did the right thing…

 

loader ran successfully, inserted 3 memberships, deleted 0 memberships, total membership count: 3

loader ran successfully, inserted 0 memberships, deleted 0 memberships, total membership count: 3

 

Thanks,

Chris

I wonder if the 2.1 loader will be much of an improvement?

 

Thanks,

Ugh… yeah, I guess that patch wont work.  The deltas assume the col is subject_id… so…  any chance you can wait a couple of weeks for 2.1?  J

 

Thanks,

Chris

Chris,

 

Okay, I patched the code and the loader was able to get the subjects loaded with uclaPPID.  It is very slow.  It also removed  a membership that I entered manually. 

 

gsh 2% loaderRunOneJob(group);

loader ran successfully, inserted 47441 memberships, deleted 47427 memberships, total membership

count: 66610

 

This was the second run.  Why did it delete and recreate so many memberships?  I thought it was using deltas for the process.

 

Thanks,

 

Lawrence

Im bringing this back to the list to share with others.

 

Basically the problem is that your loader query is returning uclaUniversityId, and that is not the subject_id, the subject_id is uclaPPID.

 

It is *very * inefficient to do it this way… since each time the loader runs a query, it will have to resolve all those subjects (LDAP lookup for each membership).  If you can have the query join to a lookup table to resolve to the uclaPPID, then you wont have to do lookups since the uclaPPID is the subjectId in the grouper_members table.  This is the best way to go.

 

In Grouper 2.1 you can use a findByIdentifier() to resolve loader subjects with a subject_identifier column, but still it is inefficient.  If you want to go down the uclaUniversityId route pre-2.1, we can patch the code… its right here in GrouperLoaderResultset.java:

 

FROM:

 

          this.subject = SubjectFinder.getSource(subjectSourceId).getSubject(subjectId, true);

          //CH 20091013: we need the loader to be based on subjectId to eliminate lookups...

          //this.subject = SubjectFinder.getSource(subjectSourceId).getSubject(subjectId, false);

          //if (this.subject == null) {

          //  this.subject = SubjectFinder.getSource(subjectSourceId).getSubjectByIdentifier(subjectId, true);

          //}

 

TO:

 

          this.subject = SubjectFinder.getSource(subjectSourceId).getSubject(subjectId, false);

          if (this.subject == null) {

            this.subject = SubjectFinder.getSource(subjectSourceId).getSubjectByIdentifier(subjectId, true);

          }

 

Thanks,

Chris

Here is the output.  Yes, searchSubject is configured to use uclaPPID and that’s incompatible with uclaUniversityId – so what is the proper configuration to  solve the issue?  I’ve tried the things that seem obvious.

 

Thanks,

What happens when you run this in gsh?

 

      grouperSession = GrouperSession.startRootSession();

      SubjectFinder.findByIdAndSource("6032xxxxxx", "ldap", true);
