    Memory of RES shown in top

    975148
      I had a query whether the memory shown in top command in the RES column (the actual physical memory the task has used) for an Oracle process is the memory allocated or the memory used by a process?

      I hope, my question is clear whether memory in RES is allocated or memory used.

      Please revert with the reply to my query.

      Regards

          what is result when you SUM (add up) all the values in the RES column?
          How does SUM compare to total RAM in this system?

            Thanks for your answer. When I am adding up the RES column, it seems to be similar to the used memory in line 1 of the output, 15909.

            total used free shared buffers cached
            Mem: 16050 15909 141 0 377 13470
            -/+ buffers/cache: 2062 13988
            Swap: 24575 896 23679

            It may be meaning that the memory in the RES column is the memory allocated as it seems to sum up with used memory mentioned above. Request you to please confirm on this.
