It is recommended that you install the Version 8.1 OLAP server component
with Version 8.1 client products. Client products include the Application
Manager, Spreadsheet Add-ins for Microsoft Excel and Lotus 1-2-3,
and the Runtime Client.
There are limitations when you mix different versions of clients and servers
in the same environment:
- Newer clients with older servers
- Using a client that is newer than the server is not recommended or supported.
- Older clients with newer servers
- Using a client that is older than the server version is not supported.
However, some clients of previous releases might work with the Version 8.1
server, although with feature limitations.
Be careful when modifying Version
8.1 databases or outlines with earlier releases of Application Manager. If
you save a Version 8.1 database that contains new Version 8.1 features with
an earlier release of the Application Manager, the new features may be stripped
from the database.
Depending on the service level of an older client,
it might not be able to connect with a newer server. Additionally, the newer
server might issue messages that are incorrect in the context of the older
client.
- One client with many servers
- If you need to connect a client to several OLAP servers on different
machines or operating systems, it is recommended that you make them all the
same version and service level. Your client should at least be at the same
as the lowest level server. If you experience problems, you might need to
use different client machines to match up with the appropriate host, or upgrade
all clients and servers to the same service level.
- Different versions of clients on the same client system
- If you install more than one client component on the same computer,
such as Spreadsheet Add-in and Application Manager, make sure that all of
the components are on the same release level. Version 8.1 clients share.dll files that may not work with earlier client components.
- IBM components with Hyperion components
- IBM does not support mixing OLAP clients and servers from IBM with OLAP
clients and servers from Hyperion Solutions. There are some differences in
feature mixes, levels, and some issues in licensing that may cause problems,
even though mixing IBM with Hyperion products might appear to work in some
situations.
