ACFRPTRX report involves INFO and Rule database and can have lot of read requests.
Because primary databases are read by ACFRPTRX utility, security checks which require access to primary databases may have to wait. Therefore, it is recommended to run ACFRPTRX utility while no or few jobs are running.
This report can impact i/o to live database. It depends how the job is canceled. If standard JES $CANCEL command is issued to cancel the job,then should be okay.
