Hi Ulrich, We set CKPTLINE=66,CKPTPAGE=100 (default), then CheckPoint Intveral = 66 * 100 = 6600 lines. Say we have 2.5 million lines printed (in 5 mins interval), then checkpoint count = 378. Does it counts ? to spike up JES2 cpu? On Fri, Jun 10, 2011 at 12:49 AM, Ulrich Krueger <[email protected]> wrote:
