Hi, in 10g documentation it is recommand to run system statistics for the CBO can decide the best plan to use with information on CPU and I/O, but in RAC architecture, i had 5 nodes, and 2 nodes is for batch job and 3 nodes for OLTP if some of my instance run batch job and other

run oltp and Oracle had just one dictionnary table for keeping stats, what can i do with this? if i gather stats on oltp server, my batch

job server will not run plan correctly and vis versa....

anyone has an idea how to treate this?

Thanks for your anwser

Pierre
