Overhead due to "Allow Multiple Instance"

[SAMEENA]

Hi,
For loading large volume of records from a sequential file to a DB2 database table,I noticed that the speed inreased significantly(it almost doubled) if I checked the "Allow Multiple Instance" chek box.

I just want to know if this would inrease overhead in some way or would it have any impact on the other jobs which are running at the same time?

Thanks in advance.

Be more specific. You enabled the MI option - but did you actually run multiple copies of the job at the same time? If not, then I would think your performance increase was due to other factors.

"Allow Multiple Instance" is to enable the job to run with multiple instance. it shouldn't enhance/deter the performance of any job
