One question on RAC architecture

   Hi All,

I am a novice to oracle RAC. I have a question encountered in my daily work.

My DB is RAC 4 nodes. At the beginning, my batch system ran on dedicated node say node 1. It owned this node completely.

Another testing batch system(copy of my current system) ran on node2 and node3, on which there are some other systems to run.

The management team thought that our system should run much faster than testing system because it has a dedicated instance. But the reality seems opposite.

The test system is a replication of my real system, so the amount of data, table strucutes and load strategy are very close.

Howdy, Stranger!
