DSXchange

Hi
Initially we were getting warnings that DS is running on 8 cpu's but license is for 4 only, now we have upgraded the licence .

I would like to know what changes should I do in DataStage to make effective usage of CPU's

Fortunately, you don't really need to make any changes at all after adding CPUs to your system! You might experiment with changin your PX configuration to optimize balance, but you don't have to.
