Thanks KG.
There were underlying OS I/O issues. The SA is looking to fix the same.

Please respond
to ORACLE-L
Rajesh:
Typically DBWR has to free up some buffers when you want to read something
from the disk. During this process there are chances
that you will be waiting for your local buffer (i.e blocks
dirtied/invalidated by your session) to be written to disk. During this
time
the
waits are shown as local write waits.
BTW do you have any other write waits or just seeing local waits? And also
are you noticing any timeouts for this waits? Typically
we wait for local wait up to one second and spin (or retry) again..
Timeouts
for local write indicates a serious problem unless you
have tiny buffer cache or extremely slow disk'
