Mohd, The simple answer is that unreferenced pages will be stolen so that the available frame queue does not go to zero. However the ways and means with which pages chosen to be moved to and from the Page datasets is rather more complex than that statement.
I suggest you read the Initialization and Tuning guide to get an understanding of how processor resources are managed. http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/iea2e151/CONTENTS ?SHELF=EZ2ZO10L.bks&DT=20080119071214#3.4.2.4 You may also want to look at conference proceedings from CMG and Share for information. Memory management is one area where z/OS is by far the consummate Operating System, and it would be good for you to understand why.
