When the "let's go to Windows!" crowd was here, we in Tech Services were allowed to ask questions of the vendors who were going to do the conversion and post-conversion support. One of our questions was along the lines of: "It is 2 am and a report job just terminated with errors. What do we do?" The answer was along the lines of: "Recompile the application with debugging information. Now have the programmer do a single step until the error reoccurs." Our subsequent question was something like: "The process had run for 3 hours at full speed before the error occurred. Do you have an estimate of how long the process would need to run with the programmer single-stepping through it to reach the same point in its processing?" Dead silence. The entire mind set of the convert-now team was that "batch" was not needed anymore. If a report was needed, the user would simply do an "ad hoc" request to get it. Nothing said about the fact that this doesn't work for printing insurance policies. When we do this, we can print thousands at a time. Again, being in insurance, there are BIG PENALITIES for not getting things done in a timely manner. -- John McKown Senior Systems Programmer HealthMarkets Keeping the Promise of Affordable Coverage Administrative Services Group Information Technology The information contained in this e-mail message may be privileged and/or confidential.
