1. What is the connectivity? VPN over satellite has one set of tradeoffs; direct Ethernet another. 2. Is there really *that* much data? A megabyte or two every couple of hours is not going to be a problem no matter how you do it (within reason). The best form of "compression" might be to restrict the data to only what the recipient needs, and to transmit it in a more compact form than character. But maintainability/debugability is often more important than absolute speed.

Have an application that has both a mainframe and a desktop component. The z/OS side is the data generating side that creates some statistical data. The desktop is used for a GUI to display the data. The current state of the application is that the z/OS side creates some summary data in CSV format, and the desktop picks it up using FTP. I want to get away from summary data and FTP, and give the desktop application a 'closer look' at the data before it is summarized. The z/OS component already produces all of the data the desktop would need, but it is in character format. I could just open a pipe between the desktop and z/OS, and shove the data down the pipe. Desktop application is smart enough to parse out the data it needs from the records. But, the volume of records could get fairly large in some instances. Since it is character data, it probably lends itself well to some type of compression. Does anyone know of a compression product that runs on both platforms? 2nd question. The z/OS application could compute the amount of data to be transmitted over the pipe prior to creating the data. What affects the speed of transfer besides the size of the pipe? How important is the size of the data block on each PUT? Thanks in advance for any help on this. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
