Home -> Community -> Mailing Lists -> Oracle-L -> Tune for 'db file sequential read'
On querying the v$session_event, I could see one
process taking a very large wait time. The process
takes about 4 Hrs to complete on *this* instance (A),
whereas it takes a few minutes on another instance(B)
with almost same amount of data. The Metalink pages
suggest to test by increasing DB_BLOCK_BUFFERS, but
the interesting thing is that instance A's SGA is
128M, whereas instance B's is 44M. Any suggestions ?
