HALT- Interrupting transfers

This command is used to suspend one or all the send and/or receive transfers, with the partners selected.

The transfers halted are set to the H phasestep in the catalog. They can be reactivated:

  • By an operator START command
  • On receiving a transfer reactivation request from the partner

See also LISTCAT.

Transfer CFT Local Administrator ensures the integrity of the data in case of interruption and, depending on the protocol used, authorizes the restarting of the transfer from the last synchronization point set before the interruption, or simply from the beginning of the file.

You can use the HALT command to interrupt a transfer on Transfer CFT. This interruption changes the entry to the H phasestep. Alternatively, the KEEP command changes the entry to the K phasestep.

An accidental halt due to a network incident, a protocol error or a software or hardware interrupt, makes the entry change to the H, K, or D phasestep, with the diagnostic codes specifying the origin. For more information refer to the Transfer CFT Codes, Diagnostics and Messages topics.

In requester mode, a transfer in the D state (phase T and phasestep D) is automatically restarted. A transfer in the K or H phasestep must be manually restarted by a START command.
