Error description

  • ERROR DESCRIPTION :

The DB2 server could unexpectedly terminate with the following
call stack during the compilation of a statement
that contains one or more predicates in a WHERE clause that use
the TRANSLATE, UCASE, UPPER, LCASE, or LOWER functions:

sqlno_ff_analyse_func_expr__FP13sqlno_globalsP19sqlno_ff_essenti
als
sqlno_ff_compute_atomprd__FP13sqlno_globalsP19sqlno_ff_essential
s
sqlno_ff_compute__FP13sqlno_globalsP19sqlno_ff_essentialsP16
sqlno_int_stats_scan__FP13sqlno_globals13SQLNN_BOOLEANl + 0x650
sqlno_jits_sa__FP13sqlno_globals + 0x1E8
sqlno_exe__FP9sqlnq_qur + 0x1460


For example:

  WHERE  TRANSLATE(col) = 'AA' ...


The problem may only occur if the predicate is applied to a
derived query block and the AUTO_STMT_STATS database
configuration parameter is turned on.

Local fix

  • LOCAL FIX :
Turn off the AUTO_STMT_STATS database configuration parameter

Problem summary

  • DB2 SERVER MAY ABEND DURING COMPILATION OF SQL STATEMENT
CONTAINING CERTAIN PREDICATES WHEN AUTO_STMT_STATS IS ENABLED

Problem conclusion

  • First fixed in DB2 UDB Version 9.5, FixPak 4

Temporary fix
