Automation scripts leveraging WebLogic Scripting Tool (WLST). Each subfolder contains:
.py WLST script (core logic).sh wrapper (shell script for execution).properties files (for connection/config parameters; not required for some tools)change_server_listenport/
Change or list the non-SSL listen port for a specific WebLogic Server instance (e.g., 7003 => 7004).
log_settings_admin/: For AdminServer (extended log format does not apply)log_settings_ms/: For Managed Serversset_default_stagingmode/
Configure the default deployment staging mode (stage/nostage) for a server.
set_machine_nmtype/
Set the NodeManager type (SSL or Plain) for a machine. Useful when managing server instances with NodeManager.
set_autorestart/
Enable or disable the AutoRestart setting for a given server. Useful when managing server instances with NodeManager.
set_restartdelaysec/
Set the restart delay (in seconds) for a server. Use together with the set_autorestart tool.
MaxRequestParameterCount) for a server.ORACLE_HOME, WL_HOME, DOMAIN_HOME) and ulimits for the oracle user. Adjust as needed.
⚠️ Many Automation-WLST scripts read this file to ensure environment variables are set. Most scripts will not function properly unless this file is deployed and contains the appropriate values.
rsyslog rules to redirect journald logs for WebLogic server instances to /var/log/weblogic/* when the servers are run under systemd.Systemd service definitions for running WebLogic as managed Linux services.
weblogic-admin.service
Unit file for Admin Server
weblogic@.service
Template unit for Managed Servers (parameterized by instance name, e.g., ‘MS1’)
sysconfig/weblogic-AdminServer
Environment file used by the systemd unit for Admin Server
sysconfig/weblogic-MS1
Sample environment file used by the systemd unit for a Managed Server named ‘MS1’. The name after the - corresponds to the server instance.
change-wls-java_home.sh
Safely modifies, reports, or backs up the JAVA_HOME path parameter in WebLogic/Oracle Middleware OUI properties and configuration files.
As you may know, updating the JDK version on an already installed/configured Middleware server often involves a series of tedious and error-prone steps.
This tool is designed with safety in mind; it provides a ‘list-only’ mode runtime option and an in-file ‘SAFE_MODE’ switch.
💡 Caution & Tips The script provides extensive help output, which can be displayed by using the
-hoption. It also provides a detailed ‘Procedure Outline: How this script is involved in WebLogic Server JDK Replacement’ in the comments, which describes the practical replacement procedure. Be sure to read these instructions carefully for a successful replacement.
derby-disable.sh
Disables the built-in Java DB (derby.jar) by renaming the jar file (💀 demo DB; can consume production server resources).
jre-securerandom-fix.sh
For JDK 11+: Switches securerandom.source from /dev/random to /dev/urandom in java.security to avoid entropy depletion and speed up JVM start.
jre8-securerandom-fix.sh
Same as above, but for Java 8, which requires /dev/./urandom (with a dot in the path).
oracle user, with relevant environment variables set (see profile.d/oracle.sh)..properties files — be sure to check and edit these before use.All scripts and configurations are provided as-is, without warranty. Test thoroughly in a non-production environment before applying to live systems.
