The Question is: After digging through the Wizard archives, I'd like to rephrase a question I posted earlier (about an hour ago), please. -------------------------------------- How do I best send a "big" file (4gbytes+)from an INTEL-based NT-server to VMS. we have: DLT tape (ARCSERVE) TCP/IP - Multinet (FTP) Reflection software for WinNT (terminal emulator with file transfer abilities) we had SAMBA: used to work until we moved buildings. Needs to be reconfigured properly. Both COMPUTERS reside on same Ethernet link. I'm worried about band width with network file transfers. Would it take hours? days? Can we read an ARCSERVE tape? I've had no success so far with MOU/FOR or MOU/OVER=ID or EXCHANGE. Are there any utilities for this? Thanks for any help/direction you can give. Chris Holtz The Answer is : The note you are rephrasing includes details that were omitted from this note, including mention of the the database of roughly four gigabytes -- by OpenVMS standards, this database is on the small side -- and that you are working with Windows NT 3.51 and OpenVMS V7.1. The core problem here is typically not in the data transfer or the media itself, it is the format of the contents of the files being transfered. Sequential ASCII text is normally no problem. Other (proprietary) file formats can be somewhat more of a problem to access, once transfered. tar and various other "portable" file transfer tools are available for most every platform, and there are also third-party packages providing compatibility with OpenVMS BACKUP savesets on Windows NT systems. Use of a network and associated file transfer tools (such as FTP) is also another obvious approach. Also determine if the tool used to export the data from the Windows NT database has particular requirements. The Wizard is not aware of an OpenVMS tool that reads Cheyenne Arcserver format. (Please check with CA for information on CA products.) As for network bandwidth, a tranditional (slow) Ethernet network can deliver a peak rate of roughly one megabyte of data per second. Four gigabytes would thus requre roughly four thosand seconds, or slightly over an hour, at a minimum. (Slower Ethernet controllers or a network with traffic will obviously increase the amount of time required.) More recent networks, such as Fast Ethernet, deliver higher bandwidth.
