Specifies the amount of work that is directed to the application
server. If the weight value for the server is greater than the weight values
that are assigned to other servers in the cluster, then the server receives
a larger share of the server workload.
The weight that is displayed depends on the tab in which you are viewing
the information. If you are viewing the
Runtime tab, the runtime weight
displays. If you view the
Configuration tab, the configured weight
displays.
Important: If enabled, the dynamic workload manager
(DWLM) overrides any values that you enter. DWLM is enabled by default. To
disable DWLM, click Servers > Dynamic clusters >dynamic_cluster_name>
Dynamic workload management (DWLM).
On the z/OS platform, weight is used to balance some of
the workload types, but others are balanced by the z/OS system.
- For HTTP requests, weights are used to distribute HTTP traffic between
the Web server plug-in and the controller handling the clustered application
server. Assign a higher weight value to the application server that is receiving
the HTTP traffic.
- For Web services calls, information is transferred from a servant in
one application server to a controller in another application server. The
application server that receives the call has the highest weight value.
- Weight has no affect on Internet Inter-ORB Protocol (IIOP) requests.
IIOP requests are distributed to the correct application server using the
sysplex distributor.
