Raja, take a look at the V$SHARED_POOL_RESERVED. It contains column
It will tell you the size of the last request for the reserved
allocation that failed. You also have a column
about aborted requests to tell you how many aborted requests were
issued. Note that this is a RESERVED allocation.
It doesn't automatically mean 4031. Also, there is a table called
V$SHARED_POOLwhich is gone in 10g, probably
because oracle thinks that you should pay for being able to estimate the
size of your shared pool. In 10g it is called
and, as any "DBA_HIST" table should not be used without license.
Enjoy while you can.
