Database performance issue

Hello,

I have oracle 11.2 enterprise running on Windows server 2012

Application team are always complaint about the performance.

the nature of the application is that they do two things:

1- upload batch file on the application

2- Select data from database

this actions not occurs all the day, it may be 2 hours per day

i have checked the AWR report i found the below:

Soft Parse %                : 39.82

% Non-Parse CPU       : 66.70

Buffer Hit %                 : 51.30

Library Hit %                : 69.22

Execute to Parse %     : 51.24

                              Start         End

Buffer Cache        : 1,136M      1,248M

Shared Pool Size : 710M           646M

i checked the machine CPU and memory and it's Ok.
