NO_BRIDGE_IMPL() issue (avis is compiled/linked properly)

Gagan Sidhu <gagan@...>
 

Hi guys,

Currently I'm on OSX and trying to build the openMAMA libs for my system.

I understand that OSX is not officially supported, but the issue I'm experiencing is not specific to this platform.

Specifically, I build and install the avis client, copy the config_h to the suggested directories, and proceed to build mama.

The build and linking goes fine, from what I can see, however the example programs do *not* work.

I have compiled each one using a slightly modified Makefile.sample (no -lrt flag or -Xlinker before the -Bstatic/-Bdynamic).

This issue is very strange, because I saw someone else had a bridge issue but the linked library spit out an error. All I see is:

here's the dump:

Re: mamaMsg_createForWombatMsg

Stuart Beattie <SBeattie@...>
 

mamaMsg_create(), mamaMsg_createForPayload(), or mamaMsg_createForPayloadBridge() should be used instead.

 

The function mamaMsg_createForWombatMsg() does not exist in OpenMAMA.  The reference to it in the developer's guide is incorrect and will be removed when it is next updated.

Hi

There are a number of transport callback events available through OpenMAMA but not all middlewares support them all.

        MAMA_TRANSPORT_CONNECT
        MAMA_TRANSPORT_CONNECT_FAILED
        MAMA_TRANSPORT_RECONNECT
        MAMA_TRANSPORT_DISCONNECT
        MAMA_TRANSPORT_ACCEPT
        MAMA_TRANSPORT_ACCEPT_RECONNECT
        MAMA_TRANSPORT_PUBLISHER_DISCONNECT
        MAMA_TRANSPORT_QUALITY
        MAMA_TRANSPORT_NAMING_SERVICE_CONNECT
        MAMA_TRANSPORT_NAMING_SERVICE_DISCONNECT
        MAMA_TRANSPORT_WRITE_QUEUE_HIGH_WATER_MARK
        MAMA_TRANSPORT_WRITE_QUEUE_LOW_WATER_MARK

The only one connected up in avis is disconnect.

When an event like this happens at the middleware layer, it is propagated into the middleware bridge which can then call
one of the following OpenMAMA transport functions which will give the transport callback to the application,


mamaTransportImpl_invokeTransportCallback
mamaTransportImpl_disconnect
mamaTransportImpl_reconnect

If the middleware supports the events and the bridge implementation handles it correctly then you should get transport callbacks for CONNECT.

Thanks,
Ian

Hi everyone,

When using avis middleware, the transport listener does not receive any connection events except for disconnect when I shutdown the avis router.
Is that feature not supported with avis? Will other middlewares such as tibco notify the transport listener on successful connection (CONNECT event) ?

Re: dictionary publisher and avis

Ian Bell <IBell@...>
 

Hi

 

Currently avis can’t support the dictionary as the point of the dictionary is to relate fids to names and the avis payload can’t have both.

 

A way to fix this may be to modify the avis bridge so that the name and fid could be passed in a field

 

Ie currently the id string is a fid or a name we could change the id string for the field to contain the name and fid separated by a

particular character if you wan to send both.

 

If the character is not present that it could fall back to looking for a fir or a name.

 

Eg

699_wPriceLevels

Can you actually publish/subscribe a dictionary over avis? I also noticed that fields in avis message cannot have a fid and a name at the same time.

Re: Handling stale messages

Glenn McClements <gmcclements@...>
 

Hi Nicolas,
The main difference is that MAMA_QUALITY_STALE is a property of a mamaSubscription object, while MAMA_MSG_STATUS_STALE is a property of the mamaMsg object - you will receive stale messages whenever a gap is detected, and the subscription will be stale at that point also. The best way to detect whether a particular topic is stale however is to implement the relevant subscription callbacks and you will be automatically notified.

Generally you do not have to do anything to recover from stale subscriptions, as OpenMAMA will attempt to recover automatically, though you may have application specific code that you wish to invoke e.g. some warning propagated to the user. Also note that the concept of a gap and staleness is only for "market data" subscriptions, not "basic" subscriptions. 

The OpenMAMA Developer's Guide, p67-70, gives a good overview of the data quality state machine.

Hi there,

 

When looking at source code, I see two ways of notifying subscription staleness:  mamaStatus: MAMA_MSG_STATUS_STALE and mamaQuality: MAMA_QUALITY_STALE

 

What is the difference between the two and should both be handled?

Protobuf Payload Addendum

Tim Jones <Tgjones@...>
 

Hi,

 

As I am a NYSE Technologies employee, I have been asked to clarify a few points regarding the Protocol Buffers Payload for OpenMAMA library.

 

Firstly, the Protocol Buffers for OpenMAMA library is a home project, and is not, at this stage, affiliated or endorsed by NYSE Technologies or NYSE Euronext. It is entirely, independent, open-source, and is not provided with a warranty of any kind.

 

Secondly, in my license ignorance I posted that the library is distributed under the GPL. I was incorrect, it is distributed under the Lesser GPL, to match OpenMAMA. The license is viewable in the LICENSE file under the mama_protobuf repository.

 

Thanks

Tim

Protobuf Payload

Tim Jones <Tgjones@...>
 

Hi,

 

I've recently been working on an open-source demonstrator payload for OpenMAMA which wraps Google Protocol Buffers.

 

Firstly, its not complete! It builds but I have no facility to test it (and therefore debug it), as the only open-source middleware (that I know of), Avis, is not payload-agnostic.

 

It is distributed under the GPL and is available at https://github.com/tgjonesuk/mama_protobuf. Please feel free to clone, fork or whatever. If you make any progress, please let me know and I'll add you as a GitHub collaborator or commit the changes myself.

 

Thanks

Re: MAMA API not enforcing entitlement checks message

Jacobraj Benet <JBenet@...>
 

Hi Nicolas,

Good to hear that the example program was fine.

By default the OpenMAMA API does not enforce entitlement but can be enabled through the mama.properties to enforce entitlements.

For the entitlement to work, you would need to have the entitlement server, where user are authenticated to particular markets and where the reports are generated.

OEA is Entitlement API that mama uses internally to enforce entitlement.
