Hi,
I do have 2 tables, in the same table space.
And there are nearly 15 programs which run parallely to access these tables.
Some of them access either of them and some access both the tables(join).
And we do have perform issues because of the simultaneously access of the table by all the programs. So programs take 3 times the actual time required.
Is there any way to schedule the jobs to give better performance?
P.S:The jobs are run parallel because they should be completed in a time frame. So, the option of running the whole jobs one by one is ruled out.
Regards,
Om Prakash |

Probably. . .
Rather than running all 15 concurrently, you could define 3 series of jobs with 5 jobs per series or 5 series of jobs with 3 jobs per series. These would be defined to the schedule in terms of predecessors and successors. The successful completion of one job in a series would begin the execution of the next job in that series.
You might need to experiment with which jobs should be in each series for best thruput. |
