### Setting up the cluster

The setup process for JReport Enterprise Server cluster falls into the following procedures:

1. Set up the shared disk (disk array). If you do not want a shared disk, skip the step.
2. Install JReport Enterprise Server on every target computer that will join the cluster, using the appropriate license key for cluster.
3. Configure the clustered servers individually.

   You should configure each server in turn respectively, starting from the admin server, then backup servers, and finally the slave servers.

Notes:

- All servers in a JReport cluster should be set up on one platform.
- To use the old result files in `<reporthome>\history`, install the new JReport Enterprise Server to the same directory with a new license key, overriding the existing program files.
- In order to fax report set results successfully in a cluster, you need to configure the fax settings for both the admin server and backup server respectively according to your requirements.

The following topics show detailed steps for setting up a cluster:

- Setting up the shared disk
- Installing JReport Enterprise Server on cluster target computers
- Configuring the admin server
- Configuring the backup servers
- Configuring the slave servers
