Optimized configuration (1) and connections

(2) The size of each Java Virtual Machine member must be set separately. The following is an example, as shown in:

Set the heap size (the maximum value is not 50% of the physical memory), as shown below:

Modify other members according to the preceding methods.

(3) enable high-speed cache

The following lists a member who starts the high-speed cache. Other members can start the cache as follows:

Summary:

The WAS cluster is slightly different from the single-node deployment during the building process. However, the cluster environment is similar to the single-node environment for package release and optimization item configuration, and can be combined with memory for learning.

What is cluster behavior? Give an example to illustrate the Psychological Mechanism of cluster behavior.

Cluster behavior has two features: it appears as a group behavior, and its purpose is to improve the interests of the group.
The cluster behavior theory, refined social identity theory, and de-personalization theory both explain the formation, development, and maintenance of cluster behavior from different perspectives. Social Identity, anger, and efficacy describe the mental preparation status before cluster behavior occurs.
The cluster action was first proposed by Ross (1908. He pointed out that for a group, in the face of conflicts, it is necessary to show a certain Clustering behavior or a specific cluster attitude. It can be seen that the concept of cluster behavior was closely linked with "Conflict" at the beginning. In the following decades, although the researchers did not precisely define cluster behavior, almost all researchers have continued Ross's views on "group" and "Conflict" in cluster behavior (e.g ., stagner, 1941; Campbell, 1975 ).
