Automating data access resource configuration using wsadmin scripting

The scripting library provides Jython script procedures to assist in automating your environment. Use the resource management scripts to configure and manage your Java™ Database Connectivity (JDBC) configurations.

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 data access resource management procedures in the scripting library are located in the app_server_root/scriptLibraries/resources/JDBC/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, save your automation scripts to a new subdirectory in 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 scripts to perform many combinations of administration functions. Use the following sample combination of procedures to configure a JDBC provider and data source.

Procedure

  1. Verify that all of the necessary JDBC driver files are installed on your node manager. If you opt to configure a user-defined JDBC provider, check your database documentation for information about the driver files.
  2. Optional: Launch the wsadmin tool.
    Use this step to launch the wsadmin tool and connect to a server, or run the tool in local mode. If you launch the wsadmin tool, use the interactive mode examples in this topic 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:
      bin>wsadmin -conntype none -lang jython
    When the wsadmin tool launches, the system loads all scripts from the scripting library.
  3. Configure a JDBC provider.

    Run the createJDBCProvider procedure from the script library and specify the required arguments. To run the script, specify the node name, server name, name to assign to the new JDBC provider, and the implementation class name. You can optionally specify additional attributes in the following format: [["attr1", "value1"], ["attr2", "value2"]]. Custom properties for specific vendor JDBC drivers must be set on the application server data source. Consult your database documentation for information about available custom properties.

    The following example creates a JDBC provider in your configuration:
    bin>wsadmin -lang jython -c "AdminJDBC.createJDBCProvider("myNode", "myServer", "myJDBCProvider",
     "myImplementationClass", [["description", "testing"], ["xa", "false"], ["providerType", "provType"]])"
    You can also use interactive mode to run the script procedure, as the following example displays:
    wsadmin>AdminJDBC.createJDBCProvider("myNode", "myServer", "myJDBCProvider", "myImplementationClass",
     [["description", "testing"], ["xa", "false"], ["providerType", "provType"]])
    The script returns the configuration ID of the new JDBC provider.
  4. Use a template to configure a data source.

    Run the createDataSourceUsingTemplate procedure from the script library and specify the required arguments. To run the script, specify the node name, server name, JDBC provider name, configuration ID of the template to use, and the name to assign to the new data source. You can optionally specify additional attributes in the following format: [["attr1", "value1"], ["attr2", "value2"]].

    The following example uses a template to create a data source in your configuration:
    bin>wsadmin -lang jython -c "AdminJDBC.createDataSourceUsingTemplate("myNode", "myServer", "myJDBCProvider",
     "Derby JDBC Driver DataSource(templates/system|jdbc-resource-provider-templates.xml#DataSource_derby_1)",
     "myDataSource", [["authDataAlias", "myalias"], ["authMechanismPreference", "BASIC_PASSWORD"],
     ["description", "testing"], ["jndiName", "dsjndi1"], ["logMissingTransactionContext", "true"],
     ["statementCacheSize", "5"]])"
    You can also use interactive mode to run the script procedure, as the following example displays:
    wsadmin>AdminJDBC.createDataSourceUsingTemplate("myNode", "myServer", "myJDBCProvider", "Derby JDBC Driver 
     DataSource(templates/system|jdbc-resource-provider-templates.xml#DataSource_derby_1)", "myDataSource", 
     [["authDataAlias", "myalias"], ["authMechanismPreference", "BASIC_PASSWORD"], ["description", "testing"],
     ["jndiName", "dsjndi1"], ["logMissingTransactionContext", "true"], ["statementCacheSize", "5"]])
    The script returns the configuration ID of the new data source.

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.
