Re: [Quickfix-users] sequence reset, CME iLink

[QM <eqm...@nw...>]

Thanks for the notes, everyone.  For future reference, the problem was
twofold:

1 - despite having set PersistMessages and RefreshOnLogon in my config, I
was still using NullStoreFactory (a leftover from the old code) instead of
FileStoreFactory.  That meant QuickFIX wasn't reading/writing sequence
numbers to file.

2 - once QuickFIX had generated a .seqnums file, I was able to edit it and
set the proper values.

(In an ideal world, there would be an option to reset the sequence numbers
to 1:1 -- what CME refers to as an "in-session logon" -- but hand-editing
the .seqnums file works just fine for my workflow.)

Cheers
