Cancel running or waiting Fast/Unload request
This cancels a Fast/Unload request which is either running or enqueued to run.
The $FunForc function accepts one argument and returns a numeric result.
The only argument is a string that identifies the request number for the request to be cancelled. To cancel a request, a user must either have initiated the request or have system manager privileges. For example, the following code creates an asynchronous unload request, and then immediately cancels it:
%RC = $FunLoad('DATA',..,'ASYNC') IF %RC GE 0 THEN %RC = $FunForc(%RC) END IF
Syntax
%result = $FunForc(req_num)
%result is set either to 0, if the request number req_num was found and cancelled, or to an error code, if the request could not be found or cancelled.
Return codes
5 - User does not have privilege to cancel request 6 - Request not found
Usage notes
- $FunForc immediately DETACH'es a Fast/Unload task, while $FunPurg allows the Fast/Unload task to do a "clean" termination. Indiscriminate use of $FunForc could result in certain resources (such as sort work files) being left "in use". Use $FunForc when $FunPurg cannot purge the request cleanly.
