Hi,
I am researching on a critical path job and strobing the programs to see if the programs can be enhanced like remove redundant code,better I/O processing or may be apply cosmetic changes like changing SEARCH to SEARCH ALL for bigger tables etc etc.While I have all this in my mind,the strobe also doesnot say anything if a program is performing badly.
I need a starting point asto what exactly should I look at to enhance the programs.To me right now,the programs look just fine.
Any ideas/prior experiences would guide me a lot.Please reply!! |

Hello,
One place to start is to define what needs to be tuned. How did this process become "interesting"? What does "performing badly" mean in your environment? What does it perform badly compared to?
Is this a quite large single process or is it a process that is many, many users execute concurrently?
Does this program access/update vsam files or database tables? |
