129614(~1.5days), ie the same
time since the database started. The parent DBWR process is waiting on rdbms
ipc message and the seconds_in_wait time is 0.
Here's the configuration:
DB 7.3.4
db_writer=10
async_io disable
Solaris 2.6/Sun T3 Array
_db_block_write_batch=512
db_block_checkpoint_
ng no work. So, this is fine too.
db_block_checkpoint_batch determines what portion of db writes can be
used for the slow checkpoints (in 7.3). By setting this to high value, the
checkpoint will complete faster, but the speed at which DBWR cleans the
buffer cache may be slightly slower. So more
