Reactor premature CHANNEL_READY on reconnect

Mike Slade

Hi,

When the ValueAdd reactor first connects to an OMM provider the reactorChannelEventCallback is invoked with a CHANNEL_READY event only after it has received both the Field Dictionary and the Enum Dictionary. However, if the session is disconnected and the Reactor reestablishes the connection, the CHANNEL_READY event is received after it has received the Field Dictionary but before it has received the Enum Dictionary.

Is this expected behaviour? Is there a way to force the Reactor to wait until the Enum dictionary is received before sending CHANNEL_READY?

I am using ETA Java 3.5.0.0.

Thanks,

Mike

Hello @Mike Slade

Refinitiv Real-Time SDK - Java - 1.5.1.L1 consists of EMA and ETA APIs 3.5.1.L1 (3.5.1.0) which fixed this issue has been released. This is mentioned in CHANGELOG.md as shown below:

I have did a quick test and the application worked properly.

I can replicate this issue with the VA Consumer example in the package.

After creating a connection, the CHANNEL_READY event is fired after the EnumType dictionary has completed.

EnumType Dictionary complete.
Channel Ready Event: java.nio.channels.SocketChannel[connected local=/127.0.0.1:30848 remote=localhost/127.0.0.1:14002]

However, after reconnecting, the CHANNEL_READY event is fired when RWFFld dictionary has received.

Connection down reconnecting: Channel java.nio.channels.SocketChannel[connected local=/127.0.0.1:30848 remote=localhost/127.0.0.1:14002]
    Error text: An existing connection was forcibly closed by the remote host
...
Received Dictionary Response: RWFFld
Channel Ready Event: java.nio.channels.SocketChannel[connected local=/127.0.0.1:30850 remote=localhost/127.0.0.1:14002]

I have compared this behavior of ETA C and found that ETA C works correctly. The RSSL_RC_CET_CHANNEL_READY has fired after the enumerated types dictionary has completed after reconnecting.

Received Dictionary Response: RWFEnum
Enumerated Types Dictionary complete.
### Channel is Ready ###

Connection down, reconnecting.  Channel fd=464

Received Dictionary Response: RWFEnum
Enumerated Types Dictionary complete.
### Channel is Ready ###
