Entirely independent EOF on Quartz Threads - How to do?

Hi Community,

i'm currently working on a WebObjects-Application which uses the Quartz Scheduler to schedule and run thousand but thousand of jobs. Every job is doing some work in the database (Like reading, computing and then Updating/Deleting some Details from the database).

This works quite well when i only allow Quartz to start one Single Thread for Job Execution. But when i configure more than one thread, it seams that i have problems with EditingContext / ObjectStoreCoordinator-Locking or something else.

The Question is: What should i do to achieve an entirely independent EOF-Stack per Quartz Thread? If it is possible without ramping up a complete EOF-Stack per Thread, this would be even better ;)

Currently i just tried to Create a new EditingContext per Job at the start, lock the rootObjectStore, do some things and then unlock the rootObjectStore and dispose the editingContext. But that doesn't seem to work for me.
// Job Start
EOEditingContext anEditingContext = ERXEC.newEditingContext();
anEditingContext.rootObjectStore().lock();

// Job Execution

// Job End
anEditingContext.saveChanges();
anEditingContext.rootObjectStore().unlock();


It would be nice to get your suggestions about this Topic.
