On-line Operations 18-5Remote Software UpdateThis operation allows an operator to send a complete software update from one FRMto another, or between an FRM and an FRX6000. The file UPDATE.TXT contains alist of the files that will be transferred.Before an update is performed, make sure a File Transfer ID is specified inNode Defaults.Packet switching is reduced when multiple file transfers occur, because ofthe data I/O. However, there should be no other side effects.1. Press [C] at the On-Line Node Operations menu (or [B], [A], [C] from the MainMenu).2. When prompted, enter the File Transfer ID and File Transfer Pwd (password) of thenode you are updating.You will be asked: Will the remote node be using an Async terminal? If the remotenode has a directly attached VGA monitor, or if you know that one will be usedfor configuration operations, press [N]. Otherwise, press [Y].3. When asked: Initiate File Transfer?, press [Y] or [N].4. If asked: Are you sure you want to do a remote software update?, press [Y] .The "old" and new release numbers of the database will be displayed, along with thenew release number of the FRM operating software.The transfer process is as follows, and is repeated for each file, except where noted instep 1. To assure that there is enough disk space for a multiple file transfer, the largestfile will be sent first. It will be transferred only if there is enough disk space for thenew file and the file it is replacing. Once the transfer is complete, the old file will bedeleted, providing enough disk space to accommodate the next file.1. The originating node will send a message that includes a request for the remotenode's release number, the file name and size. (The request for release numberwill be sent only with the first file name.) If the release numbers of the sendingand receiving nodes are incompatible, the transfer will not occur, and an errormessage will be displayed. If this happens, contact your service representative.2. The remote node will check to make sure there is enough disk space to accept thefile; if not, the connection will be cleared and a corresponding message displayed.If there is enough disk space, the file will be transferred, and stored in the remotenode under a temporary file name until the node verifies that the file is theexpected size. (If it is not, the temporary file will be deleted.)3. If the temporary file is the expected size, the "old" file will be deleted and the newfile renamed. As the update progresses, you can press [F4] at any time to abort thetransfer and clear the connection.Once the update is complete, the sending node will clear the connection.
