Re: discarded data dictionary request
Dmitri Fedorov <dfedorov.solace@...>
Thanks Damian, Yes, referring to the data dictionary file made them working, my bad, I naively trusted to the "bookticker --help" output :-/. My focus is recap messages and how different order book updates affect it, so I don't want to use capturereplay, the bookpublisher seems to better suited for my case. Cheers Dmitri P.S. For future references, this is the pair that works, it uses non-altered configuration from the OpenMAMA 6.1.0 distribution and a locally run Apache Qpid server: > bookpublisher -v -SP WOMBAT -m qpid -tport pub -use_dict_file data/data.dict -s book.1 -threads 5 > bookticker -v -m qpid -S WOMBAT -use_dict_file data/data.dict -tport sub -s book.1 ------------------------------------- Solace Corporation accepts no liability for the content of this

Re: discarded data dictionary request
Damian Maguire <dmaguire@...>
From a really (really) quick glance at the source, I don’t think the BookPublisher code is handling dictionary requests itself. You can probably get ‘bookticker’ to work by using the same ‘-use_dict_file’ command line argument you have used for the publisher. If you’re interested in how to actually handle dictionary requests, the capturereplay example code should demonstrate that pretty well.
Cheers,
Damian

Re: order book price level number of entries
Damian Maguire <damian.j.maguire@...>
Hey Dmitri, There's probably someone who can clarify better, but I believe the difference is the 'mNumEntries' is the total number of entries which the data feed has reported is part of the book, but which may not necessarily be accessible within the MAMDA Price Level structure (for example, if the feed doesn't supply entry level information for the book we might still report the number of entries, but have nothing we can look at). The 'mNumEntriesTotal' is then the total number of entries which are actually iterable within the same structure. Looking at the logic in that snippit, I'm not convinced there's not a small issue there (I don't know that we should be setting mNumEntriesTotal as part of this logic) - it might be worth raising a bug in GitHub and someone more familiar with that code might be able to comment.

Hi Dmitri. Honestly you should have reviewed it by now. The RFC review period is supposed to be 2 weeks and it has been almost a month now so it remains closed. In saying that if you want to suggest changes, you're free to follow https://openmama.github.io/openmama_rfc_process.html#how-to-provide-rfc-feedback and it'll be considered on a best-effort basis, but you'll need to be quick as Vela (who are completing this work) may well have started work already according to the current form of the RFC.

Re: MAMDA recap message format
Dmitri Fedorov <dfedorov.solace@...>
T hanks Frank, The two different recap messages are from the same subscription at different points in time. I've looked at updates coming it, they don't look like the recap messages at all. None of them has the counter field wPlNumEntries 657 and each always has the wEntryId field 681 as "ask" or "bid" (one of the recap messages has this field removed).I see wPlNumEntries added and modified in MamdaOrderBookWriter, and wEntryId is used do drive logic in MamdaBookAtomicListener, do we have somewhere an explanation of how these two fields are used in MAMDA?I'll try to figure out why and how the wEntryId field disappears from the recap message, I suspect this is not right, would you agree?Cheers Dmitri On Sat, Jan 7, 2017 at 7:49 AM, Frank Quinn <fquinn.ni@...> wrote:

Re: MAMDA recap message format
Frank Quinn <fquinn.ni@...>
Hi Dmitri, Best place to start would be for the updates coming in. Odds are you'll find these fields are getting populated from the data source containing each delta rather than from within MAMDA itself, or that data types are different in multiple sources causing mixed results or something like that.Were the two different recap messages you specified from two different subscription or at different points in time from the same subscription?

MAMDA recap message format
Dmitri Fedorov <dfedorov.solace@...>
Hi all, I'm investigating an issue in a Solace proprietary product that uses an instance of MamdaOrderBookListener to keep track of orders and to populate recap messages. During the investigation I've come across two different formats for recap messages coming from the MamdaOrderBook->populateRecap(MamaMsg& recapMsg) call: one has ask/bid strings and the other does not. Where should I dig to find out why and how this happens? In my test case the publisher generates eight price levels (four asks and for bids), and after a few tens of thousand messages, the first recap message format I see is: [653]=PRICE:10.01 [654]=INT8:65 [655]=UINT32:1014500 [656]=UINT32:0 [657]=UINT16:2257 [658]=DATETIME:2017-01-04 22:55:57.428543 [681]=STRING:ask [682]=UINT32:500 [683]=INT8:65 }, { the second: }, { [653]=PRICE:10.01 [655]=UINT32:1006400 [656]=UINT32:0 [657]=UINT16:2221 [658]=DATETIME:2017-01-04 22:55:57.440543 [659]=INT16:0 }, { [657] is the entry count wPlNumEntries, [681], [682] and [683] are wEntryId, wEntrySize and wEntryAction, and [659] (that is missing from the first recap message format) is wPlNumAttach. hank you in advance.

Good question… the approach we had planned on taking was to allow accessors to be called and return an error if an extended value was requested via a function which doesn’t support extended values.
An argument could certainly be made to implement what you’re talking about and in terms of code, it would be the easiest thing in the world to add, but I think (after some deliberation) we should avoid it because:
1. It makes the application aware of the concept of “Extended” values, which I expect the application developer won’t want to have to consider independently 2. Whether it’s extended or not is usually irrelevant until you try to read or write to it using certain accessors in which case we have a mechanism already in there in returning an error code (which applications should already be checking) 3. It would mean introducing a method which would immediately get deprecated in MAMA 7 (as we will revisit the interface at that point to make all interfaces support extended data types)
I also have one eye on trying to steer anyone who is depending on extended data types to actually move exclusively towards methods which support extended values and use POSIX mechanisms rather than have conditional statements where they need to maintain two blocks of code – one for extended and one for the old non-extended.
