Cluster configuration scripts

The scripting library provides multiple script procedures to automate your application server configurations. Use the scripts in this topic to configure clusters with or without cluster members, using a template, and to remove clusters from your configuration. You can run each script individually, or combine procedures to create custom automation scripts.

The AdminClusterManagement script procedures are located in the app_server_root/scriptLibraries/server/V70 directory.

Use the following script procedures to configure clusters in your environment:

Use the following script procedures remove clusters and cluster members from your configuration:

createClusterMember

This script assigns a server cluster member to a specific cluster. When you create the first cluster member, a copy of that member is stored as part of the cluster data and becomes the template for all additional cluster members that you create.

Table 1. createClusterMember argument descriptions. Run the script with the cluster name, node name, and new member name arguments.

Argument

Description

clusterName

Specifies the name of the cluster to which the system adds the cluster member.

nodeName

Specifies the name of the node on which the application server resides.

newMemberName

Specifies the name to assign to the cluster member.

Syntax

AdminClusterManagement.createClusterMember(clusterName, nodeName, newMemberName)

Example usage

AdminClusterManagement.createClusterMember("myCluster", "myNode", "clusterMember1")

 

createClusterWithFirstMember

This script creates a new cluster configuration and adds the first cluster member to the cluster. Use clusters to manage a group of application servers as a single unit, and distribute client requests among the application servers that are members of the cluster. Create a cluster to balance your client requests across multiple application servers and to provide a highly available environment for your applications.

Table 2. createClusterWithFirstMember argument descriptions. Run the script with the cluster name, cluster type, node name, and server name arguments.

Argument

Description

clusterName

Specifies the name to assign to the new cluster.

clusterType

Specifies the type of cluster to create. You can specify a value of APPLICATION_SERVER, GENERIC_SERVER, orWEB_SERVER.

nodeName

Specifies the name of the node on which the cluster resides.

serverName

Specifies the name of the server to add to the cluster.

Syntax

AdminClusterManagement.createClusterWithFirstMember(clusterName, clusterType, nodeName, serverName)

Example usage

AdminClusterManagement.createClusterWithFirstMember("myCluster", "APPLICATION_SERVER", "myNode", "myServer")

createClusterWithoutMember

This script creates a new cluster configuration in your environment. Use clusters to manage a group of application servers as a single unit, and distribute client requests among the application servers that are members of the cluster. Create a cluster to balance your client requests across multiple application servers and to provide a highly available environment for your applications.

Table 3. createClusterWithoutMember argument descriptions. Run the script with the cluster name argument.

Argument

Description

clusterName

Specifies the name to assign to the new cluster.

 

Syntax

AdminClusterManagement.createClusterWithoutMember(clusterName)

Example usage

AdminClusterManagement.createClusterWithoutMember("myCluster")

 

createFirstClusterMemberWithTemplate

This script uses a template to add the first server cluster member to a specific cluster. A copy of the first cluster member that you create is stored in the cluster scope as a template. You can create the first cluster member using any existing server as a template or a default server template. You can also create a first cluster member when you create the cluster by converting a server to a cluster. When you create a first cluster member, the template of the cluster member is stored in the scope of the cluster. Additional cluster members are created using the cluster member template stored in the cluster scope

Table 4. createFirstClusterMemberWithTemplate argument descriptions. Run the script with the cluster name, node name, new member name, and template name arguments.

Argument

Description

clusterName

Specifies the name of the cluster of interest.

nodeName

Specifies the name of the node on which the application server resides.

newMemberName

Specifies the name to assign to the cluster member.

templateName

Specifies the name of the template to use to create the cluster member.

Syntax

AdminClusterManagement.createFirstClusterMemberWithTemplate(clusterName, nodeName, newMemberName, templateName)

Example usage

AdminClusterManagement.createFirstClusterMemberWithTemplate("myCluster", "myNode", "myClusterMember", "default")

createFirstClusterMemberWithTemplateNodeServer

This script uses a node with an existing application server as a template to create a new cluster member in your configuration. When you create the first cluster member, a copy of that member is stored as part of the cluster data and becomes the template for all additional cluster members that you create.

Table 5. createFirstClusterMemberWithTemplateNodeServer argument descriptions. Run the script with the cluster name, node name, new member name, template node name, and template server name arguments.

Argument

Description

clusterName

Specifies the name of the cluster to which the system adds the cluster member.

nodeName

Specifies the name of the node on which the application server resides.

newMemberName

Specifies the name to assign to the cluster member.

templateNodeName

Specifies the name of the node with an existing application server to use as the template when creating the new cluster member.

templateServerName

Specifies the name of the existing application server to use as the model when creating the new cluster member.

Syntax

AdminClusterManagement.createFirstClusterMemberWithTemplateNodeServer(clusterName, nodeName, newMemberName, newMemberName, templateNodeName, templateServerName)

Example usage

AdminClusterManagement.createFirstClusterMemberWithTemplateNodeServer("myCluster", "myNode", "newClusterMember", "myTemplateNode", "myTemplateServer")

deleteCluster

This script deletes the configuration of a server cluster. A server cluster consists of a group of application servers that are referred to as cluster members. The script deletes the server cluster and each of its cluster members.

Table 6. deleteCluster argument description. Run the script with the cluster name argument.

Argument

Description

clusterName

Specifies the name of the cluster to remove from your configuration.

Syntax

AdminClusterManagement.deleteCluster(clusterName)

Example usage

AdminClusterManagement.deleteCluster("myCluster")

deleteClusterMember

This script removes a cluster member from your cluster configuration. A cluster member is a server that belongs to a cluster.

Table 7. deleteClusterMember argument descriptions. Run the script with the cluster name, node name, and server cluster member arguments.

Argument

Description

clusterName

Specifies the name of the cluster from which to remove the cluster member.

Understanding SSL

Image
Understanding SSL: There are many ways to go about creating an SSL connection between servers,  and the best one for your situation will depend upon the type of protocol you're planning to tunnel through it. As you probably know, the Secure Sockets Layer (SSL) allows the use of encryption to protect data sent via a TCP/IP connection. The most commonly used implementation of SSL is the HTTPS protocol: a secure encrypted alternative to HTTP for transferring information over the Web. Secure Sockets Layer ( SSL ) is a computer networking protocol for securing connections between network application clients and servers over an insecure network, such as the internet. Due to numerous protocol and implementation flaws and vulnerabilities, SSL was deprecated for use on the internet by the Internet Engineering Task Force ( IETF ) in 2015 and has been replaced by the Transport Layer Security ( TLS ) protocol. While TLS and SSL are not interoperable, TLS is backwards-compatible with

WebSphere Application Server Session Management Session support allows a Web application developer to maintain state information across multiple user visits to the application.  We will cover below points 1. HTTP session management 2. Session manager configuration 3. Session identifiers 4. Local sessions 5. General properties for session management 6. Session affinity 7. Persistent session management 1.HTTP session management: When an HTTP client interacts with a servlet, the state information associated with a series of client requests is represented as an HTTP session and identified by a session ID. Session management is responsible for managing HTTP sessions, providing storage for session data, allocating session IDs, and tracking the session ID associated with each client request through the use of cookies or URL rewriting techniques. 2.Session manager configuration: Session management in WebSphere Application Server can be defined at the follow

What is WebSphere Application Server  ? WebSphere is a set of Java-based tools from IBM that allows customers to create and manage sophisticated business Web sites. The central WebSphere tool is the WebSphere Application Server (WAS), an application server that a customer can use to connect Web site users with Java applications or servlets. IBM released WebSphere Application Server 8.5 in June 2012 and 8.5.5 in June 2013 A pplication Server provides the infrastructure to host enterprise application. It handles application operation between user request to backend business application like a database, messaging, etc. Enterprise application, which is usually transactional based or heavily used, must have an application server with built-in redundancy, high availability, and performance oriented like WebSphere Application Server. Application Server usually sits between Web Server and Database or another backend like messaging, etc. Below is the typic
