RE: windows odbc connection to connection mana....

In Response To: RE: windows odbc connection to connection mana.... (Alexandre Marini)

Alexandre,

I have two problems with that article:
1) It is explaining how to setup a sqlhosts file, which windows doesn't use (Art provided a link earlier in the tread for an IBM doc that explains how to set it up on a windows system)
2) It doesn't specify a minimum CSDK version

-Justin

Hello.
Supposing you have a group of servers, it should randomly connect to all of
them.
For more information, our friend Fernando Nunes has made a complete article
about sqlhosts features, check it out:
