RE: Explain Oracle memory structure.
The Oracle RDBMS creates and uses storage on the computer hard disk and in random access memory (RAM). The portion in the computer s RAM is called memory structure. Oracle has two memory structures in the computer s RAM. The two structures are the Program Global Area (PGA) and the System Global Area (SGA).

The PGA contains data and control information for a single user process. The SGA is the memory segment that stores data that the user has retrieved from the database or data that the user wants to place into the database.
