Problem IC66160
|
Status: Geschlossen |
DB2EXFMT OUTPUT DOES NOT SHOW TO / FROM SUBSECTION LINE ON EACH TQ OPERATOR. THIS MAKE CORRELATING DB2EXFMT OUTPUT TO SNAPSHOTS |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / 950 - DB2 |
| Problembeschreibung: |
This APAR adds information about the runtime section to the
explain_argument table for "current explain mode" settings of
"explain", "yes" and "reopt", and the "explain" bind options
"yes", "all" and "reopt". With any of these explain settings,
explain will gather information during the section code
generation phase of optimization and add it to the explain
tables. This makes matching up runtime section information to
the explain generated plan much easier. The information will
show up in the db2exfmt output under each DPF Table Queue
operator as follows:
TQNUMBER: (Runtime Table Queue number)
1
TQSECNFM: (Runtime Table Queue Receives From Section #)
1
TQSECNTO: (Runtime Table Queue Sends to Section #)
0
Take note that using the explain statement (explain plan for
.... sql query ... ) does not generate a runtime section, and
thus will not generate these new explain arguments. |
