Communications Express Installation Considerations

Before installing Communications Express, consider the following planning aspects:

• You cannot use the installer to install the Universal Web Client (UWC) or Access Manager on a sparse non-root global Solaris zone. Instead, you need to manually add the packages from the distribution CD using pkgadd.

• Delegated Administrator requires that you install Access Manager and the web container (either Web Server or Application Server) on the same host.

• You can deploy Communications Express and Access Manager in both SSL and non-SSL modes, either on the same or a different web container.

• Due to a JavaScript security dependency, you must install Communications Express and Messenger Express on the same host, or Communications Express and Messaging Express Multiplexor on same host (in a multi-tiered environment).

• You can plan for a distributed deployment in which Directory Server, Messaging Server, Calendar Server, and Access Manager are installed on separate hosts.

• If you are using Calendar Server hosted domains, you enable Communications Express support for hosted domains during the configuration phase.

• You can configure Communications Express for SSL or non-SSL. If you configure SSL, you can choose between having Communications Express clients use SSL only for authentication, or to use SSL for the entire session.
