Hi Sunil

A memory leak is when an applicationd does not release its memory after its finished using it.
The effect on system performance is that an application will continually keep increasings it use of the systems memory, hence eventually causing memory bottlenecks.
It is detected by watching an application continually utilise more and more memory.
Usually to release the memory you have to restart the application. (Not ideal if its 24x7 Database!!)

See this thread for using UNIX95 to detect memory leak:
