Hi,
My job has two sources for Join Stage, 1 of them is DB2 API Stage connected to MVS DB and the other is DB2 EE Stage connected to AIX DB2. The Join Stage use column 'FILE_ID' as Join Key to perform a Left Outter join. The mode of this Join Stage is Defaulf(Parallel) and the Partition Type in the input tab is 'Auto'. The problem I met is recently I found that I can not get the expecting outcome from this Join Stage anymore. I am going to show you guys the data in the Source Stage and the outcome I got below, fyi...
Data in DB2 API Source Stage:
EVENT_NAME
FILE_ID
BATCH_NBR
FILE_NAME
STATUS
LAST_UPT_ID
LAST_UPT_TIME

What do you mean by "incorrect"? Do you get correct results if you disable parallel execution (as a test)? Have you tried explicitly partitioning on FILE_ID using a key-based algorithm? Are both inputs sorted on FILE_ID?
