What Is WebLogic Scripting Tool?


Angela Bailey

The WebLogic Scripting Tool (WLST) is a command-line scripting interface that allows administrators to automate administrative tasks in Oracle WebLogic Server. It provides a convenient way to manage and configure WebLogic domains, servers, and applications using a scripting language.

Key Features of WLST:

  • Automation: WLST enables administrators to automate repetitive or complex tasks by writing scripts. This can save time and effort in managing large-scale deployments.
  • Flexibility: WLST supports both interactive and non-interactive modes of operation.

    In interactive mode, administrators can execute commands directly from the command-line prompt, while in non-interactive mode, scripts can be executed without user intervention.

  • Scripting Language: WLST uses the Python programming language as its scripting language. This makes it easy for administrators familiar with Python to write scripts for managing WebLogic Server.
  • Access to WebLogic APIs: WLST provides access to the entire set of WebLogic Server APIs, allowing administrators to perform a wide range of administrative tasks. This includes configuring server resources, deploying applications, managing security settings, and monitoring server health.

Getting Started with WLST:

To start using WLST, you need to launch the command-line interface of your operating system and navigate to the location where Oracle WebLogic Server is installed. Once you are in the correct directory, you can run the “wlst” command to start the WLST shell.

In the WLST shell, you can execute commands interactively or write scripts to automate tasks. The basic structure of a WLST script consists of importing necessary libraries and connecting to a WebLogic domain.

To connect to a WebLogic domain, you can use the following command:

connect(username, password, url)

Replace “username”, “password”, and “url” with the appropriate values for your WebLogic domain. Once connected, you can execute various commands to manage your domain.

Example WLST Script:

Here’s an example of a WLST script that deploys an application to a WebLogic Server:

# Import necessary libraries
import os
import sys

# Connect to the WebLogic domain
connect("admin", "password", "t3://localhost:7001")

# Deploy the application
deploy('myapp', '/path/to/myapp.war')

This script first imports the required libraries and then connects to the WebLogic domain using the provided username, password, and URL. Finally, it deploys the application located at “/path/to/myapp.war” with the name “myapp”.


The WebLogic Scripting Tool (WLST) is a powerful command-line interface that allows administrators to automate administrative tasks in Oracle WebLogic Server. With its automation capabilities and access to WebLogic APIs, WLST provides a flexible and efficient way to manage and configure WebLogic domains. By leveraging its scripting language and features, administrators can streamline their operations and improve productivity.
