Citrix Systems 4.2 instruction

Upgrade from 2.2.x to 4.2

12.Choose "U" to upgrade the package.

13.If you have made changes to your existing copy of the configuration files components.xml, db.properties, or server.xml in your previous-version CloudPlatform installation, the changes will be preserved in the upgrade. However, you need to do the following steps to place these changes in a new version of the file which is compatible with version 4.2.

Note

How will you know whether you need to do this? If the upgrade output in the previous step included a message like the following, then some custom content was found in your old file, and you need to merge the two files:

warning: /etc/cloud.rpmsave/management/components.xml created as /etc/cloudstack/

management/components.xml.rpmnew

a.Make a backup copy of your previous version file. For example: (substitute the file name components.xml, db.properties, or server.xml in these commands as needed)

#mv /etc/cloudstack/management/components.xml /etc/cloudstack/management/ components.xml-backup

b.Copy the *.rpmnew file to create a new file. For example:

#cp -ap /etc/cloudstack/management/components.xml.rpmnew /etc/cloudstack/management/ components.xml

c.Merge your changes from the backup file into the new file. For example:

#vi /etc/cloudstack/management/components.xml

14.On the management server node, run the following command. It is recommended that you use the command-line flags to provide your own encryption keys. See Password and Key Encryption in the Installation Guide.

#cloudstack-setup-encryption -e <encryption_type> -m <management_server_key> -k <database_key>

When used without arguments, as in the following example, the default encryption type and keys will be used:

•(Optional) For encryption_type, use file or web to indicate the technique used to pass in the database encryption password. Default: file.

•(Optional) For management_server_key, substitute the default key that is used to encrypt confidential parameters in the properties file. Default: password. It is highly recommended that you replace this with a more secure value

4.2 specifications

Citrix Systems, a leading provider of virtualization solutions and cloud computing technologies, released version 4.2 of its popular software, Citrix XenApp, which was previously known as Presentation Server. This version marked a significant evolution in providing users with remote access to applications and desktops, emphasizing simplicity, performance, and security.

One of the standout features of Citrix XenApp 4.2 is its improved application streaming capabilities. This technology allows applications to be delivered to users in real-time, reducing the need for extensive local installations and enhancing the user experience. With application streaming, administrators can efficiently manage applications on a central server while ensuring that users have immediate access to the necessary tools.

Another highlight of this version is the enhanced security measures put in place to protect sensitive data. Citrix XenApp 4.2 includes support for SSL encryption, providing a secure communication channel for data transmitted between the server and clients. This is particularly crucial for businesses that need to comply with strict data protection regulations. Additionally, the integration of endpoint security features ensures that unauthorized access to applications is minimized.

Performance enhancements are also a critical focus in this release. Citrix optimized the delivery of applications over various network conditions, ensuring that users experience minimal latency regardless of their location. This was achieved through the incorporation of SmartAccess and SmartControl technologies, which allow administrators to set policies based on user roles, device types, and network conditions. This level of granularity enables organization-wide security without compromising on usability.

The user experience was further improved with a revamped interface, making it easier for end-users to access their applications and data. Simplified menus, clear navigation paths, and the ability to customize user settings contributed to a more efficient workflow, allowing users to focus on their tasks rather than struggling with the software.

Finally, Citrix XenApp 4.2 was designed to be highly scalable. Organizations of all sizes could deploy this solution to deliver applications efficiently, adapting to their specific needs as their user base grows or changes. This flexibility is crucial for businesses looking to future-proof their IT investments while maintaining optimal performance.

In summary, Citrix XenApp 4.2 stands out with its enhanced application streaming, robust security features, improved performance under varying conditions, user-friendly interface, and scalability, making it an ideal choice for organizations seeking to leverage virtualization for remote access to applications and desktops.
