DB2 - Problembeschreibung

Problem IC99746 Status: Geschlossen

FORCE APPLICATION OF LOAD FROM CURSOR MIGHT CAUSE LOAD TO HANG

Produkt:
DB2 FOR LUW / DB2FORLUW / A50 - DB2
Problembeschreibung:
Load from cursor might hang when the following conditions are 
met: 
 
-- Large UTIL_HEAP_SZ (database parameter) and/or DATA BUFFER 
(load parameter) are set. 
-- Large CPU_PARALLELISM and/or DISK_PARALLELISM are specified 
explicitly or implicitly. 
-- Load a large amount of data from cursor into target table. 
-- Load is forced/interrupted during loading data. 
 
Coordinator agent will have stack below waiting for all LOAD 
EDU's to finish clean up: 
 
__nanosleep 
ossSleep 
sqlorest 
sqlulTermEDU 
sqluvload 
sqluLoadPartition 
sqlu_register_table_load 
 
while all the LOAD EDUs are blocked by "msgsnd()" when sending 
feedback to the agent: 
 
msgsnd 
sqlowqueInternal 
sqlowque 
sqluWriteQueue 
sqluCleanupAndSendFinalMessage
