Disabling Optimistic Locking at Runtime

[Colin Kilburn]

Hello,

I am using optimistic locking for a few classes/tables in my 
application.   However, in certain circumstances when my application 
starts up, I want to disable optimistic locking for the lifetime of the 
application.   I have tried to modify the repository metadata at 
runtime, but I still get an OptimisticLockException when trying to 
update an object whose locking field is not consistent with the 
database.    I've included my disabling method below.  Is there anything 
I can add to it to completely disable this mechanism?

private void disableOptimisticLocking() {
   DescriptorRepository r = 
MetadataManager.getInstance().getGlobalRepository();
   Map dt = r.getDescriptorTable();
       
   Iterator i = dt.entrySet().iterator();
   while (i.hasNext()) {
       Map.Entry entry = (Map.Entry) i.next();
       ClassDescriptor cd = (ClassDescriptor) entry.getValue();

       if (!cd.isInterface() && cd.isLocking()) {
           FieldDescriptor[] lockingFields = cd.getLockingFields();
           for (int j = 0; j < lockingFields.length; j++) {
               FieldDescriptor descriptor = lockingFields[j];
               descriptor.setLocking(false);
               descriptor.setUpdateLock(false);
           }
       }
   }
}

Thanks in advance,
Colin
