Upgrading to a clustered listener environment
Follow these instructions if you want to upgrade your existing single-listener configuration for Unica Campaign to a clustered listener configuration. A listener cluster is a set of two or more listeners that act as a unit to provide load balancing and high availability. Unica Campaign listener clusters are Active-Active; meaning each node serves requests using the load-balanced approach. Each Unica Campaign listener provides an interface between front-end clients (such as the Unica Campaign web application) and back-end analytical server processes.

Upgrade Guide
- Upgrade Guide
  - Upgrade overview
    An upgrade of Unica Campaign and Unica Optimize is complete when you upgrade, configure, and deploy and configure Unica Campaign and Unica Optimize. The Unica Campaign Upgrade Guide provides detailed information about upgrading, configuring, and deploying Unica Campaign and Unica Optimize.
  - Planning the Unica Campaign and Unica Optimize upgrade
    You can upgrade your current version of Unica Campaign to bring it up-to-date with the latest features.
  - Upgrading Unica Campaign and Unica Optimize
    You can upgrade Unica Campaign and Unica Optimize to version 12.0 from version 11.1.0 only.
  - Upgrade considerations to Deliver
  - Deploying Unica Campaign web application
    You can deploy the Unica Campaign web application by using an EAR file or you can deploy the individual WAR files.
  - Configuring Unica Campaign and Unica Optimize after deployment
    After you deploy Unica Campaign, you must verify that the Unica Campaign listener is running, set up the Unica Campaign system user, set Unica Campaign configuration properties, and verify the Unica Campaign installation.
  - Configuring multiple partitions for Unica Campaign
    In the Unica family of products, partitions provide a way to secure the data that is associated with different groups of users. When you configure Unica Campaign or a related Unica application to operate with multiple partitions, users can see each partition as a separate instance of the application. There is no indication that other partitions exist on the same computer.

When you configure Unica Campaign or a related Unica application to operate with multiple partitions, users can see each partition as a separate instance of the application. There is no indication that other partitions exist on the same computer.
  - Configuring multiple partitions in Deliver
    Configure multiple partitions in Unica Deliver to isolate and secure data for different groups of Unica Deliver users. As each partition has its own set of configuration properties, you can customize Unica Deliver for each group of users.
  - Unica Platform utilities
    This section provides an overview of the Unica Platform utilities, including some details that apply to all the utilities and which are not included in the individual utility descriptions.
  - Uninstalling Unica Campaign and Unica Optimize
    Run the Unica Campaign and Unica Optimize uninstaller to uninstall Unica Campaign and Unica Optimize. When you run the uninstaller, the files that were created during the installation process are removed. For example, files such as configuration files, installer registry information, and user data are removed from the computer.
  - Unica Campaign web application clustering
    You can configure the Unica Campaign web application (J2EE application) in a cluster by completing additional tasks during the Unica Campaign installation.

    - Shared network location for clustered listeners: campaignSharedHome
      A clustered listener configuration for Unica Campaign requires that certain files and folders must be shared and accessible to all listeners in a cluster. Therefore, you must have a shared file system in place.

Diagram of listener clustering

This diagram illustrates a three-node listener cluster configuration.

Note: The following summary provides a high-level overview of the components. Details are provided in separate topics.

A cluster consists of multiple listener nodes. Each node (unica_aclsnr) is on a separate physical machine, and each node has a native ODBC connection to the Unica Campaign system database. As with a single-node configuration, each unica_aclsnr process spawns additional back-end processes for logins and flowcharts.

Each node also has a connection to a back-end user database (not shown in diagram).

In a clustered configuration, one node acts as the master listener. The job of the master listener is to perform load balancing by distributing incoming requests to each node. The Unica Campaign web application sends client requests over TCP/IP, and the load balancer component communicates with clustered nodes over TCP/IP. All nodes share a network file system, so they can access shared files. Additionally, each node has its own local tmp folder and its own set of files that are not shared.
