datapump inctype explanation in oracle

PGA monitoring views in oracle

-
The PGA(program or process global area)is a memory area(ram) that stores data and control information for a single process. It typically contais a sort_area,hash_area,session_cursor cache. pga areas can be sized manually by setting parameters like hash_area_size,sort_area_size Hash_Area_Size Oracle hash_area_size is simple. The hash_area_size parameter value defaults to 1.5 times sort_area_size and is used for performing hash joins of Oracle tables. The higher the value for hash_area_size, the higher the propensity for the CBO to use a hash join. The value for hash_area_size is quickly the oracle show parameters command SQL > show parameter hash_area_size; The hash_area_size is obsolete if you are using pga_aggregate_target,but in oracle 9i with pga_aggregate_target ,a hash area size cannot exceed 5% of the pga area many increase the hash_area_size with " alter session get hash_area_size " or with a use_hash hint. Sort_Area_Size The sort_area_size parameters control the RA...
