Problem IC72979
|
Status: Closed |
QUERY COMPILER INCORRECTLY RETURNS SQLCODE -101 WHEN IT SHOULD NOT. |
| product: |
DB2 FOR LUW / DB2FORLUW / 950 - DB2 |
| Problem description: |
Under rare conditions, the query compiler might return sqlcode
-101 when it should not.
A db2trc flw output shows one of the following functions
sqlno_find_jp_hash_table or sqlno_do_insert_qpt in the call
stack when function sqlno_alloc_aub receives return code
SQLO_NOMEM_STMTH from the functions it calls.
Starting with DB2 Version 9.5 Fix Pack 6 and DB2 Version 9.7 Fix
Pack 3, confirmation of the problem can be made from db2 diaglog
entries. At DIAGLEVEL 3 or higher, the db2 diaglog file shows
a compiler error stack for rc -2144272209 logged by sqlnn_cmpl.
The error stack will contain one of the problematic functions
sqlno_find_jp_hash_table or sqlno_do_insert_qpt. The following
is an example with sqlno_find_jp_hash_table in
the error stack.
