ColdFusion 11 Update 1 (release date September 22 2014) includes important bug fixes for Connector, Installation, Database, and ORM. 

Prerequisites

1. On 64-bit computer, use 32-bit JRE for 32-bit ColdFusion and 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.
   1. http.proxyHost
   2. http.proxyPort
   3. http.proxyUser
   4. http.proxyPassword
3. For ColdFusion running on JEE application servers, stop all application server instances before installing the update.

Installation

For instructions on how to install this update, see Server Update section.

• The update can be installed from the Administrator of a ColdFusion instance or through the command-line option.
• Windows users can launch the ColdFusion Administrator using Start > All Programs > Adobe > Coldfusion 11 > Administrator.
• Microsoft Windows 7, Windows 8, Windows Server 2008, and Windows Server 2012 users must use the “Run as Administrator” option to launch wsconfig tool at {cf_install_home}/{instance_name}/runtime/bin .
• If you get the following error when installing the update using the Download and Install option, ensure that the folder{cf_install_home}/{instance_name}/hf_updates has write permission: "An error occurred when performing a file operation write on file {cf_install_home}/{instance_name}/hf-updates/hotfix_001.properties".

Post installation

This update addresses two important bug fixes for IIS connector. If you are facing connector-related issues mentioned above in the "Issues Fixed" section, then reconfigure the connector using wsconfig tool. It is available at {cf_install_home}/{instance_name}/runtime/bin.

Important Note: Adobe recommends that you make a backup of all connector configuration files before you consider reconfiguring the connector. Connector-related configuration files are available at {cf_install_home}/config/wsconfig/.

Uninstalling

To uninstall the update, do 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-11-00001/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-11-00001}/backup directory to {cf_install_home}/{instance_name}/

Remember

1. In the ColdFusion Administrator, if you see the update listed in both Available Updates and Installed Updates, it could be a caching issue. Do the following:
   1. Navigate to Server Update > Updates > Available Updates and click Check For Updates.
   2. Press Ctrl+F5 to remove the bulb notification from the top banner of the ColdFusion Administrator.
2. If ColdFusion server doesn't start automatically (ps -ef | grep -i coldfusion command indicates ColdFusion is running, but the ColdFusion Administrator cannot be accessed), restart the server manually after applying the update. This issue is rare and occurs on few Unix or Linux-based operating systems (when buffer allocation size of the machine console is almost zero).
