This section lists the software and hardware requirements for Active Cluster. All data sources and databases that are supported with this release of TDV are supported by Active Cluster.

The data source capability files and LDAP properties file are not automatically synchronized with other machines in the cluster. Therefore, if you customized the ldap.properties file or data source capability files on a TDV Server that will be in a cluster, you need to copy these files manually to all computers that are members of the cluster.

For example, if you modified the external domain configuration file and the data source capability file for DB2, you would need to copy the following files to all computers that are or will become members of the cluster:

A digital certificate ensures the identity of a particular computer and the data it transmits to another computer. Every server in an Active Cluster must have a digital certificate set up on the computer. A trial digital certificate is shipped with TDV Server but must be changed to ensure full security. See Updating the Digital Certificate to Secure Cluster Communication for how to do this.

See Installation Requirements and Support Information for a list of the platforms and protocols supported by Active Cluster.

Active Cluster requires an additional 4 MB of disk space.

Although a load balancer is not required to be used with Active Cluster, it is highly recommended to achieve the maximum benefits of using Active Cluster.
