Jonathan Lewis,

		Hi, lewis,have you ever see any big system with large shared pool size? This week I saw a mobile telecom system running ops 8163, have 8GB sga, with 3GB of shared_pool_size and About 5GB of data buffer.(Physical memory is  16GB)
		I never configured a system with shared_pool_size larger than 200MB(my current system is 200MB).But that oracle is installed by oracle china, so i wonder if this kind of configuration is reasonable? I do not have enough time to analyze that system, but I do not think Oracle china is giving the customer the right parameter about shared_pool, can you give your opinion?
	Thanks.
