Re: DRDA / MS SQL Server

Bill, in order to talk to SQL Server using embedded SQL, Microsoft has to give you what is called an "application request driver program". This is not something IBM will or should provide - it is just like the need for vendors to provide ODBC drivers for Windows to get to their data. I do not see that this is part of HIS. David Delisi can comment further, I hope. HIS seems to be only for getting to iSeries and other IBM platforms from Windows, not the other way around.
I am very interested in whether MS has provided this ARDPGM for the iSeries - it would be named on the ADDRDBDIRE command, to register the SQL Server system for use in RPG programs with embedded SQL. IBM has provided its WebSphere Data Integrator (whatever the name - I lose track) that has an app running on a Windows box that uses ODBC or OLE/DB to talk to whatever database. And it is DRDA-enabled. But you don't want to know how expensive it is.
I work for a company that has an alternative solution (blatant vendor response here). If HIS gives you the ability to get to SQL Server data FROM an RPG program, then go with that. Otherwise, you could look at our RPG2SQL product. It is similar in architecture to the IBM product, in that there is a PC server app in the middle that uses available ODBC or OLE/DB resources. One thing it does allow that embedded SQL does not is, several connections can be left open, with record positioning intact.
Anyway, if interested, give me a shout at vern@xxxxxxxxxxxxxxx or 888.RJS.SOFT and I can give you a quick demo. (end of blatant vendor response)
There is an article at www.iseries.ibm.com/db2 that discusses the several alternatives, including Java, our solution (in passing), and the IBM one, which it promotes. Kent Milligan wrote it, and it is a good article.

I need to connect to a SQL Server.  We've been using a JDBC connection that
has been working well.  We're also using file 'feeds' which are a nightmare
IMHO.  Now with more demand for additional data that is stored in the SQL
Server, I'm taking a closer look.  They bought the Host Integration Server
(HIS) software so that may be an option for access from the midrange machine
as well.

Does anyone have pointers on how to connect either directly to the SQL
Server or how to utilize HIS from the midrange machine using embeded SQL?
