HPQ-70: First paragraph in the section
- ". . . enough space in the partition for the application client
to write any buffered logical object in the application client buffer to
the medium." - What is the application client buffer? Is that
different from the object buffer? If so then a definition is needed.
4.2.5 Programmable early warning
When writing, the application client
may need an indication that it is approaching early warning (see 4.2.4)
while there is enough space in the partition for the application client
to write any buffered logical objects in the application client buffer
to medium.
Application clients that need this indication
may set the PEWS field (see 8.3.8) to a value that creates a PEWZ that
allows sufficient recording space for the data that is in the application
client buffer.
===>
An application client may need the capability
to tune the system for user applications that reside inside the application
client. One of the parameters that may need tuned is how soon prior
to receiving an early warning indication the user application needs to
be notified to prepare the application client to optimally react to early
warning. This tuning may be accomplished by setting the PEWS field
(see 8.3.8) to a value that creates a PEWZ.
Figure 10 shows an example of the PEWZ.
==========> How does this look as
a draft proposal?
