    it started to use amonge 95 to 99 % of CPU Any job may use 100% of the CPU for amounts of time. A CPU usage number isn't useful unless you also supply the length of time that the measurement covered. It should be for a minimum of 10 minutes; 15 minutes is better. Also, a description of other work in the system is helpful. In particular, how does it affect work in nornal interactive jobs? Does it significantly increase response times in interactive jobs? Are other batch jobs delayed by a significant length of time? Also, a basic description of your memory pools is needed. A simple text copy of your DSPSYSSTS display is a good start. The DSPSYSSTS screen will also show your total disk capacity and usage. Along with that, it would be very useful to know how many drives you. From that info, it might be possible to ask some questions that could lead to helpful advice. Tom
