Use this procedure to analyze system performance problems.
Look in the Product Activity Log, ASM log, or HMC to determine
if any hardware errors occurred at the same time that the performance problem
occurred. Did any hardware problems occur at the same time that
the performance problem occurred?
Yes: Perform problem analysis and correct the hardware
errors. This ends the procedure.
No: The performance problems are not related to hardware. Continue
with the next step.
Perform the following steps:
Ask the customer if they have asked software support for any
software PTFs that relate to this problem.
Recommend that the customer install a cumulative PTF package
if they have not done so in the past three months.
Inform the customer that performance could possibly be improved
by having Software Support analyze the conditions.
Inform the customer that your service provider has performance
tools. Contact Software Support for more information. This ends
the procedure.
