What happens to active BW process chains (i.e. during data load) when a failover happens ?
Write transactions get canceled in case of a failover. Thus the transaction will be canceled and rolled back by the standby indexserver which will take over.
For BW process chains this means that this process step will be canceled and you will have to restart at this failed step and continue with the loading chain where it was interrupted.
If, however, the process chain was interrupted while there was no open write transaction, the loading will continue without problems.
