Re: [U2] Connecting to a Universe Database
John, You can use any UV/BASIC subroutine you like to be invoked remotely via ODBC. Some ODBC clients have various limitations on this. You can also use the IBM-supplied UCI C-API library or UniObjects or UO for Java, etc. The main design considerations you need to be aware would include: - re-using existing code make sense, but ensure you do any initialisation sequences as well (load common - file user credentials, other settings, open file variables, etc) - your subroutine should have either input or output arguments and no input/output arguments are permitted - I find it best to 'globally' catalog a subroutine, so it can be called from any account (if this applicable for your site/functionality required - make sure it does not request any terminal input (or it will abnormally terminate) - make sure you output to a log file the results of all processing (makes debugging a lot easier) to a file for both testing and production purposes How you invoke it from your remote system/application will vary.

An ODBC interface is mostly the easiest to implemented, but the slowest and hardest to debug. Especially on such an old version of UniVerse. ... From: John Castilletti David, Do you have examples for the use of UV/BASIC subroutines invoked as stored procedures from SQL Server/ Such complications are actually unnecessary. In SQL Server, your stored proc can simply open a UO.NET connection directly into UV. Or you can invoke a web service call which then invokes a BASIC subroutine - this gives you some freedom to separate tiers. See a video I created that shows how easy it is to create a web service to any MV environment: remove.pleaseNebula-RnD.com/products/gallery.htm I use mv.NET there but you can as easily use UO.NET for that simple exercise. [AD] Having watched this discussion to see what suggestions came up, I would be remiss not to mention that mv.NET is an ideal solution for a few reasons, and that my company, Nebula RD, is a worldwide provider of mv.NET and related development services. - No need to upgrade your DBMS. - You can access your DBMS in a few ways, whether in a UniObjects-like manner by opening a connection and running a BASIC program, or writing to files/items directly. Or you can create a simple middle-tier that looks like any other relational model (with DataSets, DataTables, Columns, Rows, etc) and you don't need to do anything to your data or dicts to get these benefits. We can provide an interface for you, to your spec, and you won't need to deal with the details, or I can provide you with a free 30 day evaluation of mv.NET to see if it meets your needs as a developer.
