I have been getting ora-04031 errors, even though I have much free space
within my shared_pool - probably too much free actually. I set up some
scripts to run every 10 minutes and as recently as 3 minutes before my
ora-04031 errors started again, my shared_pool free memory was 26M based on
the query:
select sysdate, bytes
from v$sgastat
where pool = 'shared pool'
and name = 'free memory';
and myhit ratio was 99.16.
Finally, from Steve Adams site, I ran the following query, and you can see
where the errors start.
RUN_DATE RECURRENT_CHUNKS TRANSIENT_CHUNKS FLUSHED_CHUNKS
PINS_AND_RELEASED ORA_4031_ERRORS LAST_ERROR_SIZE

Can someone point out some other things to research? I am thinking that
even though I have free space in memory , maybe it is fragmeneted?
