Transfer an application to a member server sample script for Liberty Collectives

Transfer an application to a member server

Description

In IBM WebSphere Application Server Network Deployment Version 8.5.5, Liberty profile has introduced the Liberty collective feature. Refer to information about collectives in the IBM WebSphere Application Server Version 8.5.5 information center for more specifics.

The transferAppToServer.py sample demonstrates how to call the FileTransfer MBean from a Jython script to transfer an application file to a member server.

  • The FileTransfer MBean operation used:
    • uploadFile

transferAppToServer.py script

This sample script demonstrates how to transfer an application to a member server with the given server name, server host name and server usr directory. A connection is made to the collective controller located at the given host and port, and the request to upload the application file is passed to the FileTransfer MBean.

Because this script uses the FileTransfer MBean to upload one or more files, the remoteFileAccess element must be specified in the server.xml of the server that will receive the file(s). Without this you will get a file permission error when using the script. Here is an example of a remoteFileAccess element:

<remoteFileAccess>

<writeDir>${server.config.dir}</writeDir>

</remoteFileAccess>

For further information and examples for remoteFileAccess, please visit the Information Center for “WebSphere Application Server V8.5 Liberty profile” and search for “List of provided MBean”, “remoteFileAccess” or “Configuration elements in the server.xml” information center topics.

File transfer and server commands require remote execution and access (RXA). Before running this sample script, ensure the target system(s) are configured for remote access. For more information on the remote execution and access requirements and setup, refer to Requirements for using Remote Execution and Access (RXA) in the information center.

Running the script pushes the application file to the apps directory of the member server. You still need to make a configuration update to the server.xml of the member server to add the application element and any other elements that the application needs. Automation of such changes can be seen in other sample scripts such as updateServerConfig.py or transferConfigToServer.py.
