Reuters ADS feed and SFC query: Subscribing with Duplicate RICS

PCS is an instance of AssetControl which as multiple instances the SELECTFEED interface ( i.e. uses SFC api to source reuters data).

There are two interfaces called SFC_ECL and SFC_ECL_EOD.

  • SFC_ECL SELECTFEED gateway has securities requesting for the ASK, BID price data
  • SFC_ECL_EOD SELECTFEED gateway has securities requesting for the CLOSE price data

Can ADS on the TREP box cope with the same RIC code subscribed on multiple SELECTFEED interfaces using P2P ( which is ADS I believe)?

After the gateways are up for at least 4 hours or so it stops and repeatedly prints out the error message below:

Tue Nov 15 10:31:29 2016

ssl_errno = 43 on channel = 1

message =

source =

item =

An SSL IPC message has been received which contains an undefined Protocol Type.

file = src/ssl/eddispch.c, line = 4483, Channel = 1

ssl_DispatchOne: Failure: Failed to parse the SSL message

Any assistance would be appreciated.

Additional questions: (1) is this a new problem? If so what has changed?, (2) Are you using a very old version of SFC lib?

I have analysed the IPCTRACE file and found that the API incorrectly parsed the incoming image.

The data part must start with 340XX, not “I is well”.

I assume that it could be the incompatible version of SSL APIs used by the application. The SFC application depends on the libssl48.so. SFC C++ 4.6.3.L1 required SSL API 4.8.F86.

-bash-3.00$ strings libssl48.so | grep sapi
VERSION  sapi4.8.F86
sapi4.8.F86

Using different versions of SSL API with SFC C++ 4.6.3.L1 can cause unexpected behaviours.

I understand you have raised a support ticket for your query.

As an ADS can handle the same RIC being requested from multiple sessions / clients etc then the support ticket route is the best approach for daignosing the cause of the issue.
