Sun Java Communications Suite 5 Release Notes

Messaging Server Installation, Upgrade, and Uninstallation

This section describes known issues with installing, upgrading, and uninstalling Messaging Server.


This version of Messaging Server does not support a staged rolling upgrade with minimum downtime in a symmetric HA environment.

With Messaging Server 5.2, you could install the Messaging Server more than once on the same machine and patch the different installations separately. This capability enabled support for minimal-downtime staged rolling upgrades.


You must use the Communications Services installer to install a cluster agent for Messaging Server.

To install Messaging Server in a Sun Cluster environment, see Sun Cluster Software Example in Sun Java Communications Suite 5 Installation Guide.

When Messaging Server is configured (immediately after installation), the Select Components to Configure screen displays the following components: Message Transfer Agent, Message Store, Messenger Express, Delegated Administrator LDAP entries, and Messaging Multiplexor.

However, all selected components show 0 bytes on the screen.
