UNIT 4 Hardware Capacity Verification

Question 1

What could you do if you saw a CPU bottleneck? How might you fix it?

Answer 1

1) Check top 40 CPU processes

2) Check if our cpu load can be distributed to other servers

Question 2

What would you do if you saw a memory bottleneck? How might you fix it?

Answer 2

1) If it’s a database process check ST04

2) If its work process check SM50

Question 5

What are the KPIs for memory bottlenecks on Unix? on Windows?

Answer 5

UNIX: we have memory bottleneck when more then 20% of ram is swapped out per hour

WINDOWS: 25% of ram is swapped in per hour

Question 6

What indicates a CPU bottleneck is occurring?

Answer 6

When processing time is more than twice CPU time indicates CPU bottle neck
