statement mentions possible problems found by the analysis and makes

recommendations for correcting them. This might include a hardware

reconfiguration.

• A performance analysis for each processor in the system with regard to its

utilization, memory capacity, and failure impact on the remaining processors. This

part of the statement section also points out potential problems and suggests ways

of improving performance.

• An analysis for each disk volume in the system with regard to cache performance

and request queue time. This part of the statement section also has

recommendations for reallocating cache blocks and points to possible reasons for

inadequate performance.

The text statements are contained in a GPA EDIT file named TUNEDATA. You can

customize the statements to suit your needs by altering the text with a text editor. You

can also omit the statements from the standard report by deleting everything but the

first statement in the file. See Section 2: Running GPA, for details of these

procedures.
