Hi Centinul,
Thanks for the link. Got it that its a initial size and it can grow!!... From the link posted by sybrand(thanks sybrand) in calculating the Shared_pool_size
SQL> SELECT SUM(BYTES)/(1024*1024*1024) FROM V$DATAFILE;
SELECT SUM(BYTES)/(1024*1024*1024) FROM V$LOGFILE a, V$LOG b
WHERE a.group#=b.group#;
SELECT SUM(BYTES)/(1024*1024*1024) FROM V$TEMPFILE WHERE
status='ONLINE';
SUM(BYTES)/(1024*1024*1024)

Around 960gb of db sizeDisk group is exernal redunancy..and the guide says (Every 100G of space needs 1M of extra shared pool) + 2M) so ideally the shared_pool_size of my db should be approximately 30M...so setting of 2.5gb of shared pool size am wasting the remaining memory !!!! Is that?
