| Problem description: | |
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.
