This thread is challenging: you have the solution in a MOS document but you can't access it.
Must be noted that it's forbidden to post MOS content here, so people with access to the document will not be allowed to post the solution here.
By extension I would also say that people not knowing the answer before to open the document can't post solutions as that would just be the same as sharing MOS content with somebody not having access to it.
...but I can't read the solution without company id there.
Terna : can you find out in your company who has access to Oracle Support so they can open that document for you?
