Automating resource configurations using wsadmin scripting

The scripting library provides Jython script procedures to assist in automating your environment. Use the scripts in the AdminResources script library to configure mail, URL, and resource settings.

Before you begin

Before you can complete this task, you must install an application server in your environment.

About this task

A biblioteca de scripts fornece um conjunto de procedimentos para automatizar as funções mais comuns de administração de servidor de aplicativos. Há três maneiras de utilizar a biblioteca de script Jython.
  • Execute scripts da biblioteca de scripts Jython no modo interativo com a ferramenta wsadmin. Você pode ativar a ferramenta wsadmin e executar scripts individuais incluídos na biblioteca de scripts utilizando a seguinte sintaxe:
    wsadmin>AdminServerManagement.createApplicationServer("myNode", "myServer", "default")
  • Utilize um editor de texto para combinar diversos scripts da biblioteca de scripts Jython, conforme exibido na seguinte amostra:
    #
    # My Custom Jython Script - file.py
    #
    AdminServerManagement.createApplicationServer("myNode", "Server1", "default")
    AdminServerManagement.createApplicationServer("myNode", "Server2", "default")
    
    # Use one of them as the first member of a cluster
    AdminClusterManagement.createClusterWithFirstMember("myCluster", "APPLICATION_SERVER",
        "myNode", "Server1")
    
    # Add a second member to the cluster
    AdminClusterManagement.createClusterMember("myCluster", "myNode", "Server3")
    
    # Install an application
    AdminApplication.installAppWithClusterOption("DefaultApplication",
        "..\installableApps\DefaultApplication.ear", "myCluster") 
    
    # Start all servers and applications on the node
    AdminServerManagement.startAllServers("myNode")
    Salve o script customizado e execute-o na linha de comandos, conforme demonstra a seguinte sintaxe:
    bin>wsadmin -language jython -f path/to/your/jython/file.py
  • Utilize o código da biblioteca de scripts Jython como sintaxe de amostra para gravar scripts customizados. Cada exemplo de script na biblioteca de scripts demonstra boas práticas para escrever scripts wsadmin. O código da biblioteca de script está localizado no diretório app_server_root/scriptLibraries. Nesse diretório, os scripts são organizados em subdiretórios, de acordo com a funcionalidade. Por exemplo, o subdiretório app_server_root/scriptLibraries/application/V70 contém procedimentos que executam tarefas de gerenciamento de aplicativo que são aplicáveis à Versão 7.0 e posterior do produto. O subdiretório V70 nos caminhos da biblioteca de scripts não significa que os scripts contidos nesse diretório são scripts da Versão 7.0.
The resource management procedures in scripting library are located in a app_server_root/scriptLibraries/resources/ subdirectory. Each script from the directory automatically loads when you launch the wsadmin tool. To automatically load your own Jython scripts (*.py) when the wsadmin tool starts, create a new subdirectory and save existing automation scripts under the app_server_root/scriptLibraries directory.
Boas Práticas Boas Práticas: To create custom scripts using the scripting library procedures, save the modified scripts to a new subdirectory to avoid overwriting the library. Do not edit the script procedures in the scripting library.bprac

You can use the AdminResources.py scripts to perform multiple combinations of administration functions. See the documentation for the resource configuration scripts for additional scripts, argument descriptions, and syntax examples.

The example script configures a custom mail provider and session. A mail provider encapsulates a collection of protocol providers like SMTP, IMAP and POP3, while mail sessions authenticate users and controls users' access to messaging systems. Configure your own mail providers and sessions to customize how JavaMail is handled.

Procedure

  1. Optional: Launch the wsadmin tool.
    Use this step to launch the wsadmin tool and connect to a server, job manager, or administrative agent profile, or run the tool in local mode. If you launch the wsadmin tool, use the interactive mode examples to run scripts.
    • Enter the following command from the bin directory to launch the wsadmin tool and connect to a server:
      wsadmin -lang jython
    • Enter the following command from the bin directory to launch the wsadmin tool in local mode and using the Jython scripting language:
      wsadmin -conntype none -lang jython
    When the wsadmin tool launches, the system loads all scripts from the scripting library.
  2. Create a mail provider.
    Run the createMailProvider script from the AdminResources script library, specifying the node name, server name, and new mail provider name, as the following example demonstrates:
    wsadmin -lang jython -c "AdminResources.createMailProvider(myNode, myServer, newMailProvider)"
    You can also use interactive mode to run the script procedure, as the following example demonstrates:
    wsadmin>AdminResources.createMailProvider(nodeName, serverName, mailProviderName)
  3. Define the protocol provider for the mail provider.
    You can also configure custom properties, classes, JNDI name, and other mail settings with this script. See the documentation for the resource configuration scripts for argument descriptions and syntax examples. Run the configMailProvider script from the AdminResources script library to define the protocol provider, as the following example demonstrates:
    wsadmin -lang jython -c "AdminResources.configMailProvider(myNode, myServer, newMailProvider, "", "", "SOAP", "", "", "", "", "", "")"
    You can also use interactive mode to run the script procedure, as the following example demonstrates:
    wsadmin>AdminResources.configMailProvider(myNode, myServer, newMailProvider, "", "", "SOAP", "", "", "", "", "", "")
  4. Create the mail session.
    Run the createMailSession script from the AdminResources script library, specifying the node name, server name, mail provider name, mail session name, and Java™ Naming and Directory Interface (JNDI) name arguments, as the following example demonstrates:
    wsadmin -lang jython -c "AdminResources.createMailSession("myNode", "myServer", "newMailProvider", "myMailSession", "myMailSession/jndi")"
    You can also use interactive mode to run the script procedure, as the following example demonstrates:
    wsadmin>AdminResources.createMailSession("myNode", "myServer", "newMailProvider", "myMailSession", "myMailSession/jndi")
  5. Save the configuration changes.
    Utilize o seguinte exemplo de comando para salvar suas alterações de configuração:
    AdminConfig.save()
  6. Synchronize the node.
    To propagate the configuration changes to the node, run the syncNode script procedure from the AdminNodeManagement script library, specifying the node of interest, as the following example demonstrates:
    wsadmin -lang jython -c "AdminNodeManagement.syncNode("myNode")"
    You can also use interactive mode to run the script procedure, as the following example displays:
    wsadmin>AdminNodeManagement.syncNode("myNode")

Results

The wsadmin script libraries return the same output as the associated wsadmin commands. For example, the AdminServerManagement.listServers() script returns a list of available servers. The AdminClusterManagement.checkIfClusterExists() script returns a value of true if the cluster exists, or false if the cluster does not exist. If the command does not return the expected output, the script libraries return a 1 value when the script successfully runs. If the script fails, the script libraries return a -1 value and an error message with the exception.

By default, the system disables failonerror option. To enable this option, specify true as the last argument for the script procedure, as the following example displays:
wsadmin>AdminApplication.startApplicationOnCluster("myApplication","myCluster","true")

What to do next

Create custom scripts to automate your environment by combining script procedures from the scripting library. Save custom scripts to a new subdirectory of the app_server_root/scriptLibraries directory.
