Because the server type cannot be changed after it has
been installed, read this section before installing the product.
To learn about the server modes and types, see:
Modes of operation
IBM® Rational Change supports two modes of operation:
stand-alone and central.
Central mode server types
There are two complementary server types in the central
mode: central and remote. Within a central server cluster, there is
always a single central server and zero or more remote servers. Each
server, regardless of its type, can host multiple databases.
Server type selection
The server type (stand-alone, central, or remote) is designated
at the time of installation and cannot be changed thereafter.
Considerations for upgrading from a stand-alone server to a central server
To upgrade from a stand-alone server to a central server,
you must select a central CR database. Then, you must migrate all
existing CRs into the central CR database. A central server offers
many benefits. However, sometimes it is not the correct choice for
all users. Read this entire section so that you understand all of
the caveats before upgrading to a central server. When you have upgraded,
you cannot revert to a stand-alone server.
Change request process selection
When you deploy IBM Rational Change, you must decide
which change request (CR) process to install and use.
