Installing Unica Plan in a cluster

You can install Plan in a cluster by completing additional tasks while installing Plan.

To install Unica Plan in a cluster, follow the instructions from chapters 2 through 7 and supplement those instructions with information from this chapter.

When you install Unica Plan in a cluster, there are many ways to configure the installation. However, the basic process follows.

  1. Run the installers on one system: typically, the administration server (or whatever the equivalent is for your application server type).
  2. Create and share a file directory to hold the upload files for all the Unica Plan installations.
  3. Create the EAR file, and then deploy it on each machine in the cluster.
  4. Configure each system to share the same Unica Platform system tables and the same Unica Plan system tables.
  5. Configure each system to use the shared file directory.
  6. Determine which machine in the cluster should send notifications. Then suppress the notification process on all the other machines.
  7. Enable the UMOSESSIONID cookie for all servers in the cluster.
  8. Configure plan_ehcache.xml for distributed caching of templates and offer folders.
