Messaging Server: Installing Multiple Instances

With the continued move towards using Solaris Zones for creating a Messaging Server installation of multiple instances, another approach to this situation might be getting lost in the mix. New in the Communications Suite installer (available with Messaging Server 6.3p1 and 7.0) is an "altroot" power user feature that enables you to install multiple instances of Messaging Server on the same host.

For more information, see the following document:

Performing Multiple Installations with an Alternate Root

A few caveats with this approach:

  • This feature gets limited operational testing, so we recommend field testing before deployment in your environment.
  • You have to configure the different instances to use different interfaces (for all the components) to prevent conflicts.
  • There are a few Messaging Server features that just won't work (for example, SNMP), and others that might require hand-editing to work (for example, SMF startup).
  • You need to understand the implications of altroot patching as well (it creates a SVR4 package/patch datastore separate from the main OS datastore for that information).
