Automating server administration using wsadmin scripting

The scripting library provides Jython script procedures to assist in automating your environment. Use the server management scripts to configure servers, the server runtime environment, Web containers, performance monitoring, and logs. You can also use the scripts to administer your servers.

About this task

스크립트 라이브러리는 가장 일반적인 애플리케이션 서버 관리 기능을 자동화하는 프로시저 세트를 제공합니다. Jython 스크립트 라이브러리를 사용하는 방법에는 다음 세 가지가 있습니다.
  • wsadmin 도구를 사용하여 대화식 모드에서 Jython 스크립트 라이브러리의 스크립트를 실행합니다. wsadmin 도구를 실행한 후 다음 구문을 사용하여 스크립트 라이브러리에 포함된 개별 스크립트를 실행할 수 있습니다.
    wsadmin>AdminServerManagement.createApplicationServer("myNode", "myServer", "default")
  • 문서 편집기를 사용하여 다음 샘플에 표시된 것과 같이 Jython 스크립트 라이브러리의 여러 스크립트를 결합합니다.
    #
    # 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")
    사용자 정의 스크립트를 저장한 후 다음 구문 데모에 표시된 것과 같이 명령행에서 이 스크립트를 실행합니다.
    bin>wsadmin -language jython -f path/to/your/jython/file.py
  • 샘플 구문과 같이 Jython 스크립트 라이브러리 코드를 사용하여 사용자 정의 스크립트를 작성합니다. 스크립트 라이브러리의 각 스크립트 예제는 wsadmin 스크립트를 작성하는 우수 사례를 보여 줍니다. 스크립트 라이브러리 코드는 app_server_root/scriptLibraries 디렉토리에 있습니다. 이 디렉토리에서 스크립트는 기능에 따라 서브디렉토리로 구성됩니다. 예를 들어, app_server_root/scriptLibraries/application/V70 서브디렉토리에는 버전 7.0 이상 제품에 적용 가능한 애플리케이션 관리 태스크를 수행하는 프로시저가 있습니다.스크립트 라이브러리 경로의 서브디렉토리 V70은 해당 서브디렉토리의 스크립트가 버전 7.0 스크립트임을 의미하지 않습니다.
The AdminServerManagement procedures in scripting library are located in the app_server_root/scriptLibraries/servers/V70 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.
우수 사례 우수 사례: 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 AdminServerManagement.py scripts to perform multiple combinations of administration functions. Use the following steps to create an application server, connect the application server to the AdminService interface, configure Java™ virtual machine (JVM) settings, add the application server to a cluster, and propagate the changes to the node.

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:
      bin>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 an application server.
    Run the createApplicationServer script procedure from the AdminServerManagement script library, as the following example demonstrates:
    bin>wsadmin -lang jython -c "AdminServerManagement.createApplicationServer("myNode", "myServer", "default")"
    You can also use interactive mode to run the script procedure, as the following example demonstrates:
    wsadmin>AdminServerManagement.createApplicationServer("myNode", "myServer", "default")
  3. Connect the application server of interest to the AdminService interface.
    The AdminService interface is the server interface to the application server administration functions. To connect the application server to the AdminService interface, run the configureAdminService script procedure from the AdminServerManagement script library, specifying the node name, server name, and connector type arguments, as the following example demonstrates:
    bin>wsadmin -lang jython -c "AdminServerManagement.configureAdminService("myNode", "myServer", 
    "IPC", "JSR160RMI")
    You can also use interactive mode to run the script procedure, as the following example demonstrates:
    wsadmin>AdminServerManagement.configureAdminService("myNode", "myServer", "IPC", "JSR160RMI")
  4. Configure the Java virtual machine (JVM).

    As part of configuring an application server, you might define settings that enhance the way your operating system uses of the JVM. The JVM is an interpretive computing engine responsible for running the byte codes in a compiled Java program. The JVM translates the Java byte codes into the native instructions of the host machine. The application server, being a Java process, requires a JVM in order to run, and to support the Java applications running on it.

    Run the configureJavaVirtualMachine script procedure from the AdminServerManagement script library, specifying the node name, server name, whether to run the JVM in debug mode, and any debug arguments to pass to the JVM process. You can optionally specify additional configuration attributes with an attribute list. Use the following example to configure the JVM:
    bin>wsadmin -lang jython -c "AdminServerManagement.configureJavaVirtualMachine("myNode", 
    "myServer", "true", "mydebug", [["internalClassAccessMode", "RESTRICT"],
         ["disableJIT", "false"], ["verboseModeJNI", "false"]])"
    You can also use interactive mode to run the script procedure, as the following example demonstrates:
    wsadmin>AdminServerManagement.configureJavaVirtualMachine("myNode", "myServer", "true", 
    "mydebug", [["internalClassAccessMode", "RESTRICT"],
    		 ["disableJIT", "false"], ["verboseModeJNI", "false"]])
  5. Create a cluster, and add the application server as a cluster member.
    Run the createClusterWithFirstMember script procedure from the AdminClusterManagement script library, as the following example demonstrates:
    bin>wsadmin -lang jython -c "AdminClusterManagement.createClusterWithFirstMember("myCluster", 
    "APPLICATION_SERVER", "myNode", "myServer")"
    wsadmin>AdminClusterManagement.createClusterWithFirstMember("myCluster", "APPLICATION_SERVER", 
    "myNode", "myServer")
  6. Synchronize the node.
    To propagate the configuration changes to the node, run the syncNode script procedure from the AdminNodeManagement script library, and specify the node of interest, as the following example demonstrates:
    bin>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.
