Hi
I’ve developed some code based on RFA example StarterConsumer_Batchview and I need to set the hostname using an environment variable. Does the Config file support something like this :
\Connections\Connection_RSSL\hostName = ${REUTERS_HOST}
Thanks
I am not aware of a way of using Environmental variables within a .cfg file.
However, RFA does allow you to modify the StagingConfigDatabase after you load / populate it from a file.
You should then be able to add a entry to the StagingConfigDatabase with the value read from your environmental variable (e.g. read programmatically or passed in on the command line?).
result = _pStgCfgDataBase->load(flatFile, exampleRfaCfgFilePath);
if(result)
pStgCfgDatabase->setString("\\Connections\\Connection_RSSL\\serverList", "myserver1 myserver2");
result = _pCfgDataBase->merge(*_pStgCfgDataBase);
In the above example after the flatfile has been loaded, I am adding a serverList parameter to the connection - with two servers myserver1 and myserver2
You should really be using a serverList rather than hostName - to allow the API to attempt failover in case one server is not available / cannot connect / loses connection. Please read the RFA ConfigGuide description for serverList for more details.
NOTE: You can add entries to the Staging Config Database - you cannot override existing - so ensure you don't include the severList (or any other) parameter in the .cfg if you plan to add it as above.
Thank you for your reply Umer. That really helped and thanks for the server list tip too.
