This is the Elektron SDK. This SDK is an all encompassing package of all Elektron APIs. This currently includes the Elektron Message API (EMA) and the Elektron Transport API (ETA).

The Elektron Message API (EMA) is an ease of use, open source, OMM API. EMA is designed to provide clients rapid development of applications, minimizing lines of code and providing a broad range of flexibility. It provides flexible configuration with default values to simplify use and deployment. EMA is written on top of the Elektron Transport API (ETA) utilizing the Value Added Reactor and Watchlist.

The Elektron Transport API (ETA) is the re-branded Ultra Performance API (UPA). ETA is Thomson Reuters low-level Transport and OMM encoder/decoder API. It is used by the Thomson Reuters Enterprise Platform for Real Time and Elektron for the optimal distribution of OMM/RWF data and allows applications to achieve the highest performance, highest throughput, and lowest latency. ETA fully supports all OMM constructs and messages.

The Elektron-SDK has support for Linux, Windows and Solaris. Please see the individual API README.md for further details on supported platforms and compilers.

This section shows the required setup needed before you can build any of the APIs within this package.

Firstly, obtain the source from this repository. It will contain all of the required source to build EMA and ETA libraries as detailed below.

The ETA package contains transport, decoder, encoder, and cache components. The transport, decoder and encoder components are closed source and is proprietary to Thomson Reuters and the source code is not included in this package. To facilitate the ability to build all APIs of this Elektron-SDK package a 'stub' library is provided for the closed portion of the ETA. This 'stub' library will allow you to build and run, but will not provide implementation for connectivity or data handling. To get a fully functioning ETA library please see "Obtaining the ETA Binary Package" below.

####1) Build the ETA

For Linux/Solaris: Navigate to Eta/Impl

• Run makefile all to build Stub libraries and Reactor and its dependencies
• Run makefile stubs to build only the Stub libraries
• Run makefile rsslVA to build only Reactor and its dependencies

This will build both static and shared versions of the libraries.

For Windows: Navigate to Eta/Impl Select the specific vcxproj for the specific library you want to build, or use the provided solution file to build in Visual Studio. When building via the solution, select the configuration combination you want (Static, Shared, Debug, Release, etc) and select Build -> Build Solution this will create both static and shared libraries for all targets.

NOTE: You must build the Stub libaries before building the ValueAdd libraries.

If you have the corresponding ETA Binary Package you will not need to build the stubs. Please see "Obtaining the ETA Binary Package" below.

####2) Build the ETA Examples

Navigate to Eta/Applications, locate the example, performance tool, or training suite you would like to build. Run the makefile or open and build the windows solution file (when applicable) or the vcxproj.

####3) Run the ETA Examples If you have only built the 'stub' library from above, the examples will not do much. In order to get full functioning behavior of ETA you will need to get the official binaries from the customer zone. Please see "Obtaining the ETA Binary Package" below.

EMA is built upon ETA. Before you can build EMA you must build ETA as described above. Once you have the ETA libraries in place you can then build the EMA libraries and the examples.

####1) Get or build the libxml2 library.

If your system does not already have libxml2 available, you can build the version that is contained in this release. Just navigate to Ema/Src/libxml/src and run the makefile or build the windows project file.

For Linux: This is automatically built when building the EMA library (step shown below). Note that if you want to build libxml separately, a makefile is provided to you in Ema/Src/libxml/src.

For Windows: The libxml2 library will be created in Ema/Src/libxml/src/Libs. Copy the resultant Libs directory to the corresponding platform Ema/Libs directory.

####2) Build the EMA library

To build the EMA library, navigate to the Ema/Src/Access folder and run the makefile or build the windows project.

####3) Build the EMA examples

After that, you can build any of the EMA examples. Navigate to the example you wish to build and you will find both a makefile and windows project file.

####4) Get access to a providing application.

You will need a provider component to connect the EMA consumer applications to. This can be an ADS or API provider application from ETA or RFA.

####5) Run the EMA Examples

Once the provider is running and accessible, you can run the EMA examples. When running examples build using shared libraries you will need to make sure that the ETA libraries are local or in your path.

That should do it!

If you wish to have the full functionality of ETA, please get the official ETA libraries from the following.

• Category: MDS - API
• Products: Elektron SDK

Then select the following release:

eta3.0.0.L1.<platform>-binaries.rrg

Once you have downloaded these libraries, copy them to the corresponding directories under .../Eta/Libs. Note that if you are using the static library you will need to rebuild your application. For linux, if you are using the shared libraries, you may need to remove the library links and rerun the LinuxSoLink script before rebuilding.
