Questions:
1) Is the response available thru TCP/IP method for Symbol Index Mapping request?
2) At the start of transmission, do you send all Symbol Index information on the regular Multi-cast FAST channels or we have to always requires all the Symbol Index Information thru retransmission channels?

Thanks,

Symbol Index Mapping is available over TCP/IP. You just need to specify that u want response over tcp/ip in your request. I would say tcp is a prefered way for it so u dont have to think that any of messages were lost.

Yes, you can request the symbol mapping be sent via TCP/IP

2) At the start of transmission, do you send all Symbol Index information on the regular Multi-cast FAST channels or we have to always requires all the Symbol Index Information thru retransmission channels?
Symbol mapping info is sent over the production channels at the start of day for both binary and fast channels

Hello, I have some questions about correct fetch symbolMapping.

> Yes, you can request the symbol mapping be sent via TCP/IP?
I know, I must to set RetransmitMethod=1. But, I so confused:
which TCP connection must I listen?

I do following:
1 - connect (establish TCP connection) to 63.211.73.14:52001
2 - rcv heartbeat
3 - snd heartbeat, contains SourceID
4 - snd index_mapping_req
5 - try to receive answer in the same channel...

Result: last operation never executed!
see following PERL-code:
while($req_socket->recv($IndexMappingRpl, 1 << 15)) {
print "Received DATA. Size=" . length($IndexMappingRpl) . "\n";
}

Question - which TCP channel contains reply for symbol mapping request?
One, where I sent request to, or another? If another - where can I found IP address & port?

Thanks,
Max.


PS: following - dump of my IndexMapping Request (40 bytes, Source ID is changed)
