WebSphere Application Server Configuration Comparison Tool
How to check multiple server and resource configurations to:
- check for potential inconsistent behavior between application servers in a cluster.
- check for configuration creep.
- check for migration of configuration from version to version.
Important Note: The WebSphere Application Server Configuration Comparison Tool is published "as is." Please do not open a Case or PMR for tool usage issues. Best effort support can be obtained via the question and answer section of this document.
Manually configured application servers and resources are likely to have configuration differences. Finding these differences by navigating to configuration panels is error prone and time consuming. Applications servers and resources should be periodically checked for configuration differences.
The Configuration Comparison Tool (CCT) is a lightweight wsadmin script and Python report generation script which will produce HTML reports on configuration settings for the following types of resources.
- Application Servers
- Node Agents
- Global Security configuration (not Domain Security)
- SSL Configurations
- Data Sources
- J2C Resource Adapters
- JDBC Drivers
- Object Cache instances
- Servlet Cache instances
- Service Integration Bus instances
- Resource Environment Providers
- Resource Environment Entries
CCT usage scenarios:
- Isolating configuration creep: Periodic configuration snapshots can be gathered and archived. These can be used to see what configuration changes that have been made over time.
- Troubleshooting inconsistent cluster member configuration: Servers and node/server specific resource configuration anomalies can causes unexpected runtime behavior from different servers within a cluster.
- Assisting in migration to a new version of WebSphere: Cross version configuration reports can help ensure a complete migration of server and resource settings.

- ConfigDump.py on Windows systems that do not have a Unix shell (sh) will fail. Added messages documenting a workaround.
- Updated PDF presentation with ConfigReport.py prerequisites and syntax.
- May 27th, 2018
- Added a report key at the top of all report documenting values in match column and cell background colors.
- Added capability to replace a string with another value or a regular expression for the purposes of matching.
- Cell, node and server names are replaced with .* by default for matching purposes.
- June 2nd, 2018
- New report properties file processing introduced.
- Individual report properties may be set on the command line.
- Reports may be abbreviated to attributes that have differences only.
- A node agent report was added.
- Thread Pool Manager and all thread pools are now reported.
- June 17th, 2018
- Added ability to compare all SSL configurations, not just cell defaults.
- Enhanced Resources report to compare SSL configurations by the same name automatically.
