Hi Siva  

It depends on your platform. Try swap -a...

	Hi Sarah 

	I managed to do just the same.. One of our process was unnecessarily
pinning
packages and once that was removed it has become okay.. But I also happened to change a couple of this along with this. I increased the session paramter

and also increased the swap space... I dont know whether they also contributed towards solving the problem thopugh I dont see any direct correlation...

        Any way now ora-4031 is gone now...

        Babu,

        We started getting these last week when testing some new code on a 7.3.4
database. Go to metalink and search under technical bullittens for ora-4031

(note 61623.1--I think). I have also found some good information in Richard

Neimic's (TUSC) book on Tuning. Steve Adam's book on Oracle Internals and his web site had some useful scripts also (www.ixora.com.au). We made both the shared pool and the reserved pool larger and ended up unpinning a lot of

application packages that had been pinned for the last year or more--and then the errors stopped. I am trying to figure out how to predict how much memory things are going to need...

        Good luck.
