The scripting library provides Jython script procedures
to assist in automating your environment. Use the application management
scripts to install, uninstall, export, start, stop, and manage applications
in your environment.
About this task
Scripting 程式庫提供一組自動執行最常見應用程式伺服器管理功能的程序。
Jython Script 程式庫有三種使用方式。
- 利用 wsadmin 工具,以互動模式執行 Jython Script 程式庫中的 Script。
您可以啟動 wsadmin 工具,然後利用下列語法來執行併入 Script 程式庫的個別 Script:
wsadmin>AdminServerManagement.createApplicationServer("myNode", "myServer", "default")
- 利用文字編輯器,依照下列範例所示,將 Jython Script 程式庫中的若干 Script 結合起來:
#
# My Custom Jython Script - file.py
#
AdminServerManagement.createApplicationServer("myNode", "Server1", "default")
AdminServerManagement.createApplicationServer("myNode", "Server2", "default")
# 使用其中一個作為叢集的第一個成員
AdminClusterManagement.createClusterWithFirstMember("myCluster", "APPLICATION_SERVER",
"myNode", "Server1")
# 新增第二個成員到叢集中
AdminClusterManagement.createClusterMember("myCluster", "myNode", "Server3")
# 安裝應用程式
AdminApplication.installAppWithClusterOption("DefaultApplication",
"..\installableApps\DefaultApplication.ear", "myCluster")
# 啟動節點上的所有伺服器和應用程式
AdminServerManagement.startAllServers("myNode")
請將自訂 Script 儲存起來,然後依照下列語法所示,從指令行執行它:
bin>wsadmin -language jython -f path/to/your/jython/file.py
- 利用 Jython Scripting 程式庫程式碼作為撰寫自訂 Script 的語法範例。
Script 程式庫中的各個 Script 範例示範撰寫 wsadmin Script 的最佳實務。
Script 程式庫程式碼位於app_server_root/scriptLibraries 目錄中。
在這個目錄內,Script 是先依照功能組織成子目錄。
例如,app_server_root/scriptLibraries/application/V70
子目錄所包含的程序會執行適用於產品 7.0 版及更新版本的應用程式管理作業。Script 程式庫路徑中的 V70 子目錄不表示
在該子目錄中的 Script 為 7.0 版 Script。
The
application management procedures in scripting library are located
in the
app_server_root/scriptLibraries/application/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.
最佳作法: 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.

You can use the AdminApplication.py scripts
to perform multiple combinations of administration functions. Use
the following steps to use the scripting library to install an application
on a cluster and start the application:
Procedure
- 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 to run scripts.
When the wsadmin tool launches, the system
loads all scripts from the scripting library.
- Create a cluster.
Run the createClusterWithoutMember
script procedure from the AdminClusterManagement script library, and
specify the required arguments, as the following example demonstrates:
bin>wsadmin -lang jython -c "AdminClusterManagement.createClusterWithoutMember('myCluster')"
You
can also use interactive mode to run the script procedure, as the
following example demonstrates:
wsadmin>AdminClusterManagement.createClusterWithoutMember("myCluster")
- Create a cluster member for the new cluster.
Run
the createClusterMember script procedure from the AdminClusterManagement
script library, and specify the required arguments, as the following
example demonstrates:
bin>wsadmin -lang jython -c "AdminClusterManagement.createClusterMember('myCluster', 'myNode, 'myNewMember')"
You can also use interactive mode to run the script
procedure, as the following example demonstrates:
wsadmin>AdminClusterManagement.createClusterWithoutMember("myCluster", "myNode", "myNewMember")
- Install the application on the newly created cluster.
Run the installAppWithClusterOption script procedure from
the AdminApplication script library, and specify the required arguments,
as the following example demonstrates:
bin>wsadmin -lang jython -c "AdminApplication.installAppWithClusterOption('myApplication','myApplicationEar.ear','myCluster')"
You
can also use interactive mode to run the script procedure, as the
following example demonstrates:
wsadmin>AdminApplication.installAppWithClusterOption("myApplication", "myApplicationEar.ear", "myCluster")
- Start the application on the cluster.
Run
the startApplicationOnCluster script procedure from the AdminApplication
script library and specify the required arguments, as the following
example displays:
bin>wsadmin -lang jython -c "AdminApplication.startApplicationOnCluster('myApplication','myCluster')"
You
can also use interactive mode to run the script procedure, as the
following example displays:
wsadmin>AdminApplication.startApplicationOnCluster("myApplication", "myCluster")
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.
