hi Binge Jin, thank you reporting the problem and sorry for the inconveniences. Could you please provide us with a pointer to the TPCH tester tool(s) you are using such that we could try them ourselves to reproduce, analyze and hopefully fix the problem? Thanks again, Stefan On Wed, Jan 12, 2011 at 09:24:54AM +0000, 金炳娥 wrote:
