  • Patent number: 6175933
    Abstract: A system, method and program product for recovering records transferred by a file transfer program from a file transfer client to a file transfer server for storing in an I/O device by the server, wherein the file comprises multiple records in one or more blocks. A file is transferred from the file transfer client to the file transfer server a record at a time, with each record being stored in turn in memory in the server. Each record is then converted by a conversion routine. Recovery information, including the location of the first record in the block in the I/O device, is saved for each record converted by said conversion routine, and the recovery information for each record is sent to the file transfer client to be used to recover the records in the event the file transfer program is stopped.

  • Patent number: 6038638
    Abstract: A system, method and program product for freeing tape drives so that long running jobs on a computer can be paused when other applications need the drives and restarted when the drives are available again. This is accomplished by pausing and resuming applications running on a computer including accessing a tape drive, on which is mounted a first tape, by a first application running on the computer, the accessing being through a pause/resume handler; pausing the first application responsive to an operator intervention to the pause/resume handler; storing parameters in the computer including location parameters indicating where the tape drive paused; mounting a second tape on the tape drive; and accessing the tape drive by a second application running on the computer. After the second application has completed access to the tape drive, the second tape is removed from the tape drive, and the first tape is remounted.
