DB2 INSTANCE CRASHED IN DPF WHEN APPLICATION USES XML HOST VARIABLES | |

Problem description: | |
DB2 instance crashed during an "insert from select with xml host variable". INSERT INTO security (SECSYM, SDOC) SELECT T.SECSYM, T.SDOC FROM XMLTABLE('declare default element namespace "http://tpox-benchmark.com/security";$SDOC' passing xmlcast(? as xml) as "SDOC" COLUMNS "SECSYM" VARCHAR(15) PATH '*:Security/*:Symbol', "SDOC" XML PATH '.') AS T This happens because in DPF we try to collect rids for the XML document being bound in through the APPLICATION host variable and we record these rids in all subsections running on coordinator node which finally results in a bad page error during other operations. In db2diag.log, the first "severe" entry is this: 2010-06-07-17.25.40.554291-240 I2116A4348 LEVEL: Severe PID : 6471896 TID : 9770 PROC : db2sysc 0 INSTANCE: kxie NODE : 000 DB : TPOX_DSS APPHDL :
