Subject: DB2 Streaming Batch Processing Problem
Posted: Sat Sep 24, 2016 12:14 pm (GMT 5.5)
Hi,
To decrease execution time of batch job we tried to use multi streaming and split the job as follows :
Env:
1- Parallel Sysplex 2 Member
2- DB2 Ver 10
3- Account Table with 60,000,000 records RecLen 2K
4- Number of partitions Table space 80 by reange
5- Buffer pool size in each Member of data sharing is 80000 32K - LRU
6- Random Access
7- Group Buffer pool 1Gig
8- Number of CP 20 for Each Member
9- Bind The Package with Degree(ANY)
10- GBPCache set to Change TS and Index both
11- 80 stream for Each part
12- commit cont 100
There is 2 table spaces with same specific and batch just read and update both
tables heavy update.
The problem is some of the stream will finished very fast but some taking unexpected time and this situation is random for each run.
Could you please lead me to solve this problem?
Thanks
Manshadi
