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. | |
