Grouper Users - Open Discussion List

["Tom Zeller" <>]

I'm testing the 1.3 to 1.4 upgrade via the export-import process here as well, I'll check our member-groups.

For what it's worth, to speed up the import process I modified our Source adapter to iterate through our subject database and store identifiers in memory to avoid lots of database queries, looks like a 30% or so performance gain for us. 

Perhaps the subject api could benefit from 'bulkload' features, since it looks like the grouper database schema will be changing fairly often (or until Chris is happy :)

I didn't see errors the first time, but easily could have missed it.  It takes about 5 hours and has been running again for only a few, so I will let you know.  It is using tons of memory ;-)

Thanks for the help.

As far as I remember the whole xml file is loaded and all stems and groups
are created before any memberships and privileges are assigned in order to
avoid trying to use references to objects which have not been created.

Are there any errors in the log file  - especially out of memory ones?

TestXml7 appears to be a basic export-import test, it exports xml where a
member group is defined after its parent membership, and the test passes
OK
(e.g. membership checking). One would think the ordering of groups in the
import file shouldn't matter...

Yikes, that's not good.  I opened a bug assigned to me (unless someone
wants to assign it to themselves).  Hopefully I will have an answer for
you
soon (at latest by end of weekend).

I think the solution can just be something as simple as storing that
memberships in a map in memory (if not already there), and once that
group
definition is seen, then add that membership...

Is there another solution (e.g. import twice or something)?  Other
knowledge in this area?

Thanks,
Chris

Subject: [grouper-users] Export them Import Misses groups?

Following track1 to update a grouper db 1.3.1 to 1.4.0
https://wiki.internet2.edu/confluence/display/GrouperWG/v1.4+Release+No
tes.


After import is complete, groups that were members of other groups are
no longer.  The member-groups show up later in the xml file than their
parent.  Is that why import did not assign them as members?

If so, is there a way for the export to order the groups?  Could the
import read the whole file first?  Am I out of luck for ever being

able

to import?
