rdisp/softcancel_sequence SAP Parameter attribute - Sequence of delays for the signals sent at a softcancel

rdisp/softcancel_sequence is a SAP Parameter attribute which is used to control Sequence of delays for the signals sent at a softcancel information. This is available within R/3 SAP systems depending on the version and release level.

Below is the standard documentation available and a few details of the attributes values .

Parameter documentation

This parameter specifies which actions can cancel a running session when a softcancel has been triggered (for example, using 'Cancel Transaction' in SAPUI). These actions are also called softcancel sequence. The possible steps of the softcancel sequence are predefined: Step 1: Canceling the ABAP without a signal (effective during execution of an ABAP program). This happens by setting an ABAP control Step 2: Sending a softcancel signal (SIGUSR2, for example to interrupt DB queries) Step 3: Sending a SOFTKILL signal (SIGINT, for example to save the session and then end the work process) Step 4: Sending a HARDKILL signal (SIGKILL to end the work process)
The parameter specifies the time delays (separated by commas) in seconds between the different steps. The following values have a special meaning. The value 0 means that the next step is executed immediately The value -1 means that the next step (and those following) are not executed. Value n <(><<)> 0 means that the step is repeated after a time delay of abs(n) seconds. Example
Default setting rdisp/softcancel_sequence = 0,5,-5 means: Step 1 is executed Step 2 is then executed immediately. The session is not interrupted after 5 seconds, the dispatcher sends the signal SIGUSR2 every 5 seconds. Caution Since a HARDKILL can lead to inconsistencies, the softcancel sequence must not be changed.
