I've never heard of this before. Does anyone know how long it's been around? Anyone using it found any bugs, concerns, etc.? Granted, this is intended for *dedicated* server mode, it seems like a good option for our Test databases and perhaps other databases that have only a handful of users and don't require MTS. By setting PGA_AGGREGATE_TARGET=X, where X can be a value in K, M, or G, Oracle will automatically distribute this memory allocation to dedicated sessions instead of using SORT_AREA_SIZE. Here's an excerpt from the docs: "Oracle does not recommend using the SORT_AREA_SIZE parameter unless the instance is configured with the shared server option. Oracle recommends that you enable automatic sizing of SQL working areas by setting PGA_AGGREGATE_TARGET instead. SORT_AREA_SIZE is retained for backward compatibility."
