spooler, transaction logger and workspace overflow blocks. Line three,
which specifies the workspace block size, is now allowed an additional
parameter. This parameter indicates the number of blocks to be allocated
at file restore time. These blocks are allocated below SYSBASE and
their use can dramatically improve the read/write ratios on the disks. The
user should allocate all of the expected workspace requirements through
this mechanism. For example, if line three contains 10000,10, then
100,000 frames of workspace overflow are allocated below SYSBASE
and only need to be flushed once every loops (

-l

) times through the

database.

The flush program is executed from the start_flusher script. This script is
executed upon a coldstart, filerestore or warmstart. The flush program
shuts down automatically after a SHUTDOWN or WARMSTOP. By
default, the UNIX syncd daemon is replaced by the flush program. When
the flush program shuts down, it starts the UNIX syncd daemon if
necessary. Place any flush options in the start_flusher script.

./prodpicksync -l0 &

Suppresses the full flush. That is, the
UNIX syncd daemon is not replaced.

./prodpicksync -f/usr/stat/synclog &

Logs all messages to the

synclog file in /usr/stat.
