Dear all,

We have checked with Dan and indeed Greg didn't send the last document. I did it.

Nevertheless the remark about the Persitent and Sticky still true.

From my point of view:

GRPC_Persitent means that the data is available in the platform. This data can move. Thus the middleware should manage this data as asked page 6 of the standard "The underlying data middleware is explicitly asked to handle the data" (I'm agree with that, I don't see another other way).

GRPC_STICKY means that the data is available and can not move ! I found nothing in the document that explains that the data must be handle by the user (and it's sound good for me). From my point of view GRPC_STICKY is handle by the user or by the middleware. It depends on the implementation.

I agree with Yves but somewhere, I am a little bit confuse if a data mode implies a behavior rule of the middleware usage. If I want to have a Sticky data somewhere but I don't care about where. I don't give the target of the data (the middleware will do it) or if I give both informations target and sticky mode then I manage myself the data. No ?

Hello,

Not rude remarks here, but I'm a bit confused: it seems that Dan read an old

version of the document?

- I can't find the typo in the URI

- I can't find the "To discuss:" that he's talking about. But it reminds me of

the paragraph that I put there from the beginning concerning the diffusion of

a data on the servers (Broadcast, multicast, and such things that were

available in OmniStorage)...

BUT, concerning the distinction between GRPC_Persistent and GRPC_Sticky:

if we have to emphasize that the second one is when the user completely relies

on the data manager on the opposite of the second one where he manages

himself the data, can't we have a data managed by the underlying data manager

(transparent transfer) with some particularities (like if making the data

sticky or unique if the DM wants to migrate the data)?

Cheers.

.Yves.

Dear all,

We have received the final comment from Dan. With Yves we will update the

document to take into account these comments.

Best Regards,

GridRPC document (Re: [wg-all] New documents published)

Hi,

I think it generally looks fine, and the GrdiRPC session today was

helpful.  Some specific issues I have:

On page 6, the distinction between GRPC_Persistent and GRPC_Sticky is not

clear.

On page 7, "“http://myName:/myhome/data/matrix1”" has an extra ":" in the

middle.

On page 11, the items under "to discuss:" are confusing.  It seems like

these should be resolved at this point, or marked as potential

extensions.  Also, in the second item, the "on" should be "one".

Dan
