DB2 FOR LUW / DB2FORLUW / 950 - DB2

db2start fails with SQL10003 due to attaching the FMP memory set 
to an invalid address on the Solaris 10 / Sparc T4 processor 
combination with 2GB page size support.  Solaris 10 update 4 
(kernel patch 147440-04) enables 2GB pages by default. 
 
The problem is due to an inconsistency in the way DB2 rounds up 
shared segment sizes and then calculates the attach addresses of 
"fixed address" segments.  With 2GB page sizes available, DB2 
tries to attach a shared memory segment at an address that is in 
use by a previously attached segment.  This is independent of 
the actual backing page size used, it only matters what the 
largest page size is determined to be available on the system 
from the Solaris getpagesizes API.
