Prerequisites

Before you install or upgrade any HCL Unica product, you must ensure that your computer complies with all of the prerequisite software and hardware.

System requirements

For information about system requirements, see the Recommended Software Environments and Minimum System Requirements guide.

Network domain requirements

The HCL Unica products that are installed as a suite must be installed on the same network domain to comply with the browser restrictions that are designed to limit the security risks that can occur with cross-site scripting.

JVM requirements

HCL Unica applications within a suite must be deployed on a dedicated Java™ virtual machine (JVM). HCL Unica products customize the JVM that is used by the web application server. If you encounter errors that are related to the JVM, you must create an Oracle Weblogic domain or IBM Websphere profile that is dedicated to the HCL Unica products.

Knowledge requirements

To install HCL Unica products, you must have a thorough knowledge of the environment in which the products are installed. This knowledge includes knowledge about operating systems, databases, and web application servers.

Internet browser settings

Make sure that your internet browser complies with the following settings:
  • The browser must not cache web pages.
  • The browser must not block pop-up windows.

Access permissions

Verify that you have the following network permissions to complete the installation tasks:
  • Administration access for all necessary databases
    Note: Administrator must have CREATE, SELECT, INSERT, UPDATE, DELETE, and DROP rights for both tables and views.
  • Read and write access to the relevant directory and subdirectories for the operating system account that you use to run the web application server and HCL Unica components
  • Write permission for all files that you must edit
  • Write permission for all directories where you must save a file, such as the installation directory and backup directory if you are upgrading
  • Appropriate read, write, and execute permissions to run the installer
  • Root access for the Linux™ operating system.

Verify that you have the administrative password for your web application server.

For UNIX™, all installer files for Unica products must have full permissions, for example, rwxr-xr-x.

The following additional permissions are necessary for UNIX:
  • The user account that installs Collaborate and Platform must be a member of the same group as the Campaign users. This user account must have a valid home directory, and have write permissions for that directory.
  • All installer files for Unica products must have full permissions, for example, rwxr-xr-x.

JAVA_HOME environment variable

If a JAVA_HOME environment variable is defined on the computer where you install an HCL Unica product, verify that the variable points to a supported version of JRE. For information about system requirements, see the HCL Unica Recommended Software Environments and Minimum System Requirements guide.

If the JAVA_HOME environment variable points to an incorrect JRE, you must clear the JAVA_HOME variable before you run the HCL Unica installers.

You can clear the JAVA_HOME environment variable by using one of the following methods:
  • Windows™: In a command window, enter set JAVA_HOME= (leave empty) and press Enter.
  • UNIX: In the terminal, enter export JAVA_HOME= (leave empty) and press Enter.

You can clear the JAVA_HOME environment variable by running the following command in the terminal:

export JAVA_HOME= (leave empty)

The HCL Unica installer installs a JRE in the top-level directory for the HCL Unica installation. Individual HCL Unica application installers do not install a JRE. Instead, they point to the location of the JRE that is installed by the HCL Unica installer. You can reset the environment variable after all installations are complete.

For more information about the supported JRE, see the Recommended Software Environments and Minimum System Requirements guide.

Platform requirement

You must install or upgrade Platform before you install or upgrade any HCL Unica products. For each group of products that work together, you must install or upgrade Platform only once. Each product installer checks whether the required products are installed. If your product or version is not registered with Platform, a message prompts you to install or upgrade Platform before you proceed with your installation. Platform must be deployed and running before you can set any properties on the Settings > Configuration page.

Campaign requirement

You must install or upgrade and configure Campaign before you install or upgrade Collaborate.
Note: To install Collaborate with MariaDB as a system database, Collaborate base installation (12.1.0) is not required. You will have to install Collaborate 12.1.0.4 directly, where support for MariaDB as a system database has been introduced. For more details, see the Minimum Software Requirements and Environment Guide.
