| Local Fix: |
Do not use sort with DESC (NULLS FIRST) on INT or BIGINT data
types. Or, if you must use such a sort, then use the following:
db2set DB2_TCG_DEFAULT_OPTIONS="set num_page_fast_int_sort 0"
Then recycle the instance using db2stop followed by db2start and
recompile any static sections that use sort with DESC (NULLS
FIRST) on INT or BIGINT data types. |
