Technical Requirements

To install CQ WCM you need:

• JRE or JDK 1.5 (or higher). See Additional Platform Notes for further information.
• the CQ WCM quickstart jar file which also contains the required applications:
  • CRX 2.3
  • CQSE (CQ Servlet Engine) supporting 2.4 (or higher)

The following are the minimum requirements:

• 2 GB free disk space in the deployment directory
• 1.5 GB memory
  If you are using CQ DAM, you must increase the heap size when starting CQ WCM.

You will have to increase these in accordance with your operational expectations. Please see the Hardware Sizing Guidelines for further information.

This document lists the supported client and server platforms for CQ 5.5 WCM. Adobe provides several levels of support, both for our recommended configurations and for other configurations.

Adobe recommends these configurations and provides full support as part of the standard software maintenance agreement. Here we share the same support level overview as in CRX.

The configuration is tested and known bugs are fixed. Issues that are submitted by customers in the form of a fully qualified request are addressed in future releases.

Adobe cannot guarantee that the configuration works as expected, and support for these configurations is not included in the standard software maintenance agreement.

CQ5 works with the following server platforms:

• Windows 2003 with SP2 is not able to connect to WebDAV. Please see Microsoft - Software Update for Web Folders (KB907306) for full details of the manual updates which need to be made.
• Please note, that there is no differentiation on a minor version level if not stated explicitly.

CQ running in virtual machines in the cloud computing environments is supported in compliance with Adobe's support policy for all other system components (operating system, JVM, application server, etc).

For example, CQ works with virtual machines in the following cloud computing environments, similar to the deployment on other virtual servers or dedicated servers:

• Amazon EC2
  

CQ5 operates with the following versions of the Java Virtual Machine (Runtime Environment).

• The IBM JRE is only supported on IBM server platforms (AIX), or in conjunction with Websphere. For all non-IBM platforms, the Oracle JRE is supported.
• The HP JRE is only supported on HP server platforms (HP-UX). For all non-HP platforms, the Oracle JRE is supported.
• If you are using Oracle JDK 1.5.0_6, your Java VM may crash. Upgrading to Oracle JDK 1.5.0_7 solves this problem.
  

CQ5 runs on the following application servers.

You can run CQ5 without an application server, but you need a Servlet Engine. Both CRX, and therefore CQ5, ship with Adobe's CQSE servlet engine, which you can use freely and which is fully supported.

CQ Dispatcher is the caching and load balancing solution for Adobe CQ. The following platforms are supported for use with a Dispatcher and refers to the CQ Dispatcher version 4.1.0 and higher. Dispatcher can be downloaded from Adobe PackageShare.

• Other HTTP servers, built on the basis of Apache sources, only have the same support level as that of the Apachehttpd server when official Apache source distributions were used, orthey were delivered with the operating system.
• If in doubt, please ask Adobe for confirmation of the support level related to the respective server product.

CQ WCM works with the following client platforms. All browsers are tested with the default set of plug-ins and add-ons.

• Mozilla Firefox 10 is a Extended Support Release. Learn more about this on mozilla.org
• Use of WebDAV with Windows Vista is only supported with SP2. Please see Additional Platform Notes - WebDAV Clients for full details of the manual updates which need to be made.

CQ5 operates with any JSR-283 compliant repository.

This section provides special notes and more detailed information about running CQ WEM on certain platforms.

Windows 2003

Windows 2003 with SP2 cannot connect to WebDAV. See Microsoft - Software Update for Web Folders (KB907306) for full details of the manual updates that need to be made.

Windows Vista

Windows Vista requires SP2 to connect to WebDAV.

To successfully connect with Vista SP2, basic authentication for webclients must be enabled. This requires a change in the windows registry to enable Basic authentication on the client computer:

1. Locate the registry subkey:
   • HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters
2. Add the BasicAuthLevel registry entry to this subkey using a value of 2 or more.

See Microsoft Support KB 841215.

Java Versions. Generally, at least JRE 1.5 is recommended, as the following CQ WCM components or features require at least JRE 1.5:

• CRX Launchpad
• CRX Package Manager
• CQ WCM Quickstart

Java Distributions. The CQ WCM application requires only a Java Virtual Machine to run, which is provided by the Java Runtime Environment (JRE) distribution. Generally Adobe recommends using the Java Development Kit (JDK) distribution, which is a typical requirement of the Java application servers in which CQ WCM runs. Both JRE and JDK distributions are a part of the Java Standard Edition (Java SE).

Java Environment Suppliers. The IBM and HP Java environments are only supported on IBM and HP server platforms, respectively. For all non-IBM, non-HP platforms, the Oracle JRE is supported.

Servlet API Versions. CRX Launchpad web development environment, based on Apache Sling, requires a servlet engine supporting Servlet API version 2.4. All other components of CRX, including the JCR repository and CRX web application, also work with servlet engines supporting Servlet API version 2.3.

Application Server Support. CQ WCM is expected to work with any modern application servers/servlet engines (that support at least Servlet API 2.3), including popular open source products like Jetty, Apache Tomcat, Apache Geronimo or Sun GlassFish. Adobe recommends stable, non-deprecated versions of these application servers (information available on supplier websites). For production use, Adobe offers optional support for these platforms.
