This site also has tutorials, FAQs, Release Notes, and manuals
documenting the Support Tools.
Some documentation is available through other means, for example, the
Support Plus CD and the HP-UX 11i Instant Information CD. However,
the web pages should provide the latest information.
instant Capacity on Demand (iCOD)
The instant Capacity on Demand (iCOD) Version B.02.01 provides
additional processor capacity instantly on N-, L-, and V-Class servers
without requiring a system reboot. That is, this can be done dynamically
while HP-UX is running. This enables applications to take advantage of
the additional CPU power while staying online.
For HP-UX 11i, the iCOD client software bundle, in coordination with
Online Diagnostics, provides the functionality to activate processors
while online and monitor iCOD processors.
There are correlated process management and command changes that
are being made to properly track statistics related to iCOD processors.
The iCOD software supports participation in the iCOD program, iCOD
processors can be ordered and installed or added to the N-, L-, and
V-Class processors. These processors remain inactive until activated
through the iCOD client software. This allows you the flexibility to
increase the processor capacity on your servers as needed for capacity
growth. These systems must be set up to send e-mail direct to HP for
monitoring purposes of iCOD purchases.
Impact
Applications may or may not respond immediately to the additional
processor capacity without restarting. The normal OS process is to begin
scheduling processes on the newly activated processors. However, the
application may have specific threads bound to processors that aren’t
bound to the new processor and optimization to the new processing
environment may not occur until the application is restarted.
Per processor licensing by applications may also be impacted and have to
be assessed. Correlated, and HP-UX 11i approved, changes to process
