When your WebLogic Server solution needs to be scaled out with additional capacity and you
don’t want to add additional hardware, which three techniques should you us?
A.
Assign more than one managed server to a physical hardware that allows better CPU
utilization.
B.
Assign more than one application to one managed server to better utilize threads within a single
JVM process.
C.
Assign the same application to more than one managed server to load balance requests
between servers.
D.
Assign the same heap size to the managed server across the cluster for easier control of
memory footprint
E.
Create a virtualized environment with hypervisor for an easier solution
Explanation:
How about the first choice ?
I think A is also a good way to solve this problem.
First Choice means that if you want to expand/scale out you will have to add additional hardware.
Why????
Running more than one managed servers in the single host does not mean add a hardware
It’s incorrect A, because in SCALE OUT, we add hardware to add Managed Server always. By other hand in scale UP we add Managed Server in same hardware.
If you want add Managed Server in “””MODE””” scale OUT, you must add hardware.
A,D e E
Corrigindo…
as respostas corretas são:
B,D,E
B, D, E are correct options. Option A doesn’t suit here due to hardware requirement.
How come would A require additional hardware? “Assign more than one managed server to a physical hardware”, not get another physical hardware
According https://docs.oracle.com/middleware/1212/core/ASADM/scaling.htm#ASADM685 “A” is scaling up, not scaling out, so it should be incorrect.
A its incorrect
Machine scale-out is the process of moving a server, one of many on one machine, to another machine for high availability. Machine scale out is different from Managed Server scale up, which is the process of adding a new Managed Server to a machine that already has one or more Managed Servers running on it. For more information on scaling up your environment, see “Scaling Up Your Environment” in the guide Oracle Fusion Middleware Administering Oracle Fusion Middleware.
