Data change due to command

Format

• -display
• -reset
• -set

Function

Reload data change, set and reset, can be used to protect a series of command initiated actions, for example replacing a program unit with the program unit change feature. None of the commands in the series must then try to set reload data change.

Reload data change reset can be used to allow other commands to begin changing reload data. This feature can be used when the currently running reload data change command hangs or misses to reset the reload data change.

Status of reload data change due to command can be displayed.

Set reload data change to begin

Set reload data change to begin in the system. The optional information string is stored in the system and can be displayed.

Use command data_change -set or command data_change -set <information string>.

Reset reload data change

Reset reload data change due to command in the system. The optional information string can be used to reset reload data change due to a certain command. If no information string is used, the reload data change will be unconditionally reset. This should only be used if the current command hangs or when a command misses to reset.

Use command data_change -reset or command data_change -reset <information string>.

Display status of reload data change

Display status of reload data change due to command. The current reload data change command is shown. The program unit and LIM from which the command was issued is also shown.

Use command data_change -display.

Parameters

• -display

  Display status of the reload data change due to command.

• -reset

  Reset the reload data change due to command. If command information is given after the parameter, the reload data change will only be reset if the current reload changing command matches the command information.

• -set

  Set reload data change to begin in the system. An information string can be given after the parameter to indicate what change that will begin. If no information string is given, "data_change" will be used.
