DB2 FOR LUW / DB2FORLUW / A10 - DB2

During some database read/write operations where NO FILE SYSTEM 
CACHING is specified, it is recommended that the data buffers 
used for these operations be sector-aligned. Otherwise, on some 
hardware subsystems, it can result in SQLO_BPSE errors logged in 
the db2diag.log. The DB2 code that handles this situation has a 
problem. Under some timing condition, an unaligned data buffer 
is used for the NO FILE SYSTEM CACHING read/write operation.
