Hi everyone,

we use the OAI-PMH service of Fedra and have a little performance problem.

When we do an batch upload to fedora (up to 600 objects) then the OAI dies 
because of the fact that OAI gets the new/modified objects via risearch 
(Mulgara) and this takes a while...
So the OAI decides to try it later, but then nothing changed - it takes to long 
to get the result from risearch.
A bad sideeffect is, that this endless loop takes 99% CPU -> so the system is 
overloaded.
As a consequence we have to kill Tomcat, edit the lastPollDate in the MySQL DB 
of proai and restart it. 
So the system works but the objects of the batch process aren't in OAI, because 
the updated lastPollDate is after the import...

Is there another way to import the objects from Fedora to PROAI?
What can we do to get more performance for the automatic PROAI import?
Any suggestions?

Greetings from Austria,
Markus
