INITSQA & CBU processing

2008-10-29 Thread Tommy Tsui
hi all,
  After I try to activiate the CBU from 2094-401 to 2094-707, the LPAR
cannot be IPL successfully because of 878 until I set the INITSQA. Is there
any overhead while CBU activiated? How comes we need to add the default
SQA/ESQA to NIP processing after CBU activiated?

any help will be appreciated

Best regards,

Look at last section of the Apar II12396: EXHAUSTION OF INITIAL SQA ESQA 
AFTER IODF CHANGES, MIGRATION TO Z/OS 1.8 OR LATER, OR MIGRATION 
TO Z/OS 1.9 OR LATER


Did the number of (logical) processors for the LPAR grow after CBU?

Theoretically:

more processor power ---> more parallelism ---> more SQA needed...

That was the key note of the explanation we have got.
