I'm trying to gain a better understanding how RFA deals with discrepencies with the version differences of the Reuters Wire Format (RWF) between an RFA application and an ADS. The following output is from an RFA Java application built with 8.0.0.E2.all.rrg. When looking at some general RFA logs, I see this:
Connection[myNamespace::RSSL_nylabats1]: Requested version 14:1, Connected version 14:0 May 05, 2017 3:22:31 PM com.reuters.rfa.internal.connection.rssl.RSSLClientConnection processTransportConnected INFO: com.reuters.rfa.connection.rssl.myNamespace.RSSL_nylabats1 Connection[myNamespace::RSSL_nylabats1] = (14:0)
I'm making the assumption the 14:1 and 14:0 refer to the RWF versions and that it is of the format: <major ver>:<minor ver>
I can see that my RFA application is using an RWF format of [major:14, minor:1] and that the ADS supports RWF [major:14, minor:0]. I'm also assuming that they are compatible.
Would I expect to see any additional logs if the RWF versions were not compatible?
When looking further, wireshark was used to capture some additional details within an RFA Java application built with 8.0.0.L2.all.rrg. For example, I see this:
RWF Payload Contained in RIPC Socket Transport RIPC Message Message Length: 32 Flags: 0x00 Opcode: 0 Ripc Version: 12 Ping Timeout: 60 Session Flags: 0x00 Protocol Type: 0 Major Version: 14 Minor Version: 1 Host Name: T66721 IP Address: 10.5.4.73
And this as a response:
RWF Payload Contained in RIPC Socket Transport RIPC Message Message Length: 19 Flags: 0x01 Opcode: 0x01 Ripc Version: 12 Max Msg: 24 User Size: 0 Session Flags: 0x03 Ping Timeout: 30 Major Version: 14 Minor Version: 0 Compression Type: 0 Compression Level: 0
Above I can see the Major and Minor version as I previously described. What is the Ripc Version: 12 represent?
I ask because later in the wireshark dump, I see this:
RWF Payload Contained in RIPC Socket Transport RIPC Message Message Length: 67 Flags: 0x00 Opcode: 0 Ripc Version: 14 Flags: 0x08 Ping Timeout: 60 Session Flags: 0x00 Protocol Type: 0 Major Version: 14 Minor Version: 1 Host Name: T66721 IP Address: 10.5.4.73 Component Version: RFA Java Edition 8.0.0.L2.all.rrg
In here there are 2 unexpected things I noticed. The first is that the Ripc Version: 14 for some reason is different than my initial connection. Because I don't really understand what this represents, I'm also not clear as to why it changed from 12 to 14 when I initially connected. This specific connection request didn't succeed and it later performed a successful connection request with Ripc Version: 12. I also noticed there was a new line that contained the Component Version.
I'm unclear as to whether this was expected bahavior and if not, would cause any unexpected behavior later on.
