Performance tuning
Typically performance tuning takes over after the system audit
has been done. Sustained performance tuning is the only way to guarantee
throughput and related performance gains. We don't do guess work. We offer
proven industry accepted methodology to tune the batch and online PeopleSoft
tasks.
Key Benefits
- Fast online response time
- Solve concurrency issues
- Meet the batch window
- Improved resource utilization

Capabilities
- Evaluation of access path
-
SQL tuning and evaluating existing access
path can be carried out on site for your critical batch processes. We use a
wide variety of toolsets including DB2PM and RMF to isolate tuning
opportunities and focus on problem resolution for online and batch
processes. We don't do a guess work. We actually look very closely at all
possible tuning opportunities including buffer pool placement and
optimization to reduce the I/O rate, a key metric in system wide
performance. We can help you minimize your locking and contention.

- Batch process tuning
-
Meeting the batch
window is a critical requirement. It is often necessary to conduct sustained
tuning to make sure that the processes will perform within a reasonable
period. We can offer our domain expertise to help you tune critical batch
jobs.
-
- Stress tests
-
A significant part of
the online tuning is to conduct stress tests by simulating an actual
production load and monitor all the server components. Starting from the Web
Server to the Z/OS, there are many components that need to be tweaked to
make sure that the response time at peak load is acceptable.
-
"Online
tuning is actually more complex than tuning the batch work load. Experience
suggests to evaluate possible tuning opportunities for online SQL when the
time taken for a SQL task exceeds 2 seconds. What do you do?"
-
This is where our
expertise fits right in.
