Upgrade Apache Tika in Performance Monitoring Toolset

Download Apache Tika 3.2.3
Checksum: 70dd753ebefecb242d82eba0f5050f82
To upgrade Apache Tika in the Performance Monitoring Toolset (PMT), complete the following steps:
  1. Replace the existing Apache Tika version with Apache Tika 3.2.3 in the following directory: ColdFusion2025PerformanceMonitoringToolset/datastore/modules/ingest-attachment
  2. Restart the datastore service to apply the changes.

Prerequisites

  1. On 64-bit computers, use 64-bit JRE for 64-bit ColdFusion.
  2. If the ColdFusion server is behind a proxy, specify the proxy settings for the server to get the update notification and download the updates. Specify proxy settings using the system properties below in the jvm.config for a stand-alone installation, or corresponding script file for JEE installation.
    • http.proxyHost
    • http.proxyPort
    • http.proxyUser
    • http.proxyPassword
  3. For ColdFusion running on JEE application servers, stop all application server instances before installing the update.

ColdFusion JDK flag requirements

COLDFUSION 2025 (version 2025.0.0.331385)

For Application Servers
  • Apache Tomcat Application Server: edit JAVA_OPTS in the ‘Catalina.bat/sh’ file
  • WebLogic Application Server: edit JAVA_OPTIONS in the ‘startWeblogic.cmd’ file
  • WildFly/EAP Application Server: edit JAVA_OPTS in the ‘standalone.conf’ file
Set the JVM flags on a JEE installation of ColdFusion, not on a standalone installation.

Installation

ColdFusion Administrator

In Package Manager > Packages, click Check for Updates in Core Server.
After it detects an update, click Update. The core package gets updated the the latest update.
All installed packages also get updated.
Restart ColdFusion for the changes to take effect.

Install the update in offline mode manually

  1. Download the hotfix installer from the link.
  2. Download the packages zip file from this link and extract its contents to a location accessible to all ColdFusion server instances.
  3. Update "packagesurl" in cfusion/lib/neo_updates.xml of cfusion and all its child instances to point to <InstallerRepositoryUnzippedPath>/bundles/bundlesdependency.json present inside the downloaded folder.
You must have privileges to start or stop ColdFusion service and full access to the ColdFusion root directory.
  • Windows:<cf_root>\jre\bin\java.exe -jar <InstallerRepositoryUnzippedPath>\bundles\updateinstallers\hotfix-006-331564.jar
  • Linux-based platforms:<cf_root>/jre/bin/java -jar  <InstallerRepositoryUnzippedPath>/bundles/updateinstallers/hotfix-006-331564.jar
If the core server hotfix installation is successful and if there are errors or issues with packages, packages can be installed/updated from the package manager client(cfusion\bin\cfpm.bat|cfpm.sh).
Ensure that the JRE bundled with ColdFusion is used for executing the downloaded JAR. For standalone ColdFusion, this must be at, <cf_root>/jre/bin.
Install the update from a user account that has permissions to restart ColdFusion services and other configured webservers.
For further details on manually updating the application, see the help article.

Post installation

Note:
After applying this update, the ColdFusion build number should be 2025,0,06,331564

Uninstallation

To uninstall the update, perform one of the following:
  • In ColdFusion Administrator, click Uninstall in Server Update > Updates > Installed Updates.
  • Run the uninstaller for the update from the command prompt. For example, java -jar {cf_install_home}/{instance_home}/hf_updates/hf-2025-00006-331564/uninstall /uninstaller.jar
If you can't uninstall the update using the above-mentioned uninstall options, the uninstaller could be corrupted. However, you can manually uninstall the update by doing the following:
  1. Delete the update jar from {cf_install_home}/{instance_name}/lib/updates.
  2. Copy all folders from {cf_install_home}/{instance_name}/hf-updates/{hf-2025-00006-331564}/backup directory to {cf_install_home}/{instance_name}/
Note:
Uninstalling this update only removes the core update itself. Any ColdFusion packages that were updated as part of this release remain at their latest compatible versions. If you need to revert package versions, you must do so separately; uninstalling the core update does not roll back package versions automatically.
Frequently asked questions
If I uninstall ColdFusion 2025 Update 6, will all the packages installed with it be rolled back?
No. Package rollback depends on the minimum core dependency of each package:
  • Packages with a minimum core dependency of update 6 (that is, they specifically require this core level) are rolled back when you uninstall this core update.
  • Packages with a minimum core dependency of Update 4 or Update 5 remain installed at their latest compatible versions and are not automatically rolled back when you uninstall the core update.
