WRKDSKSTS,  F11

make sure all disks are nod DEGRADED, FAILED or some other
status indicating a problem...

What is your % used?  depending on storage type and configuration a
very high % will greatly effect performance.

Can some one please guide me to check the following points in the system.


Increase in the number of interactive transactions
Batch jobs.
logical DB I/O's to disk.
Number of SQL jobs processed.
Number of
SQL I/O's to disk.
CPU Batch utilisation
Average transaction rate per hour.
Disk I/O's per second and CPU pool usage.
