If you are upgrading to DB2 OLAP Integration Server Version 8.2 from a previous release, you
should assess several system environment and data migration issues before
installing the new software.
The following tasks cannot be completed until after you have installed DB2 OLAP Integration Server:
- On UNIX systems, you cannot update environment variables until after the
installation process has completed and the environment variable script files
that you need have been created (see Configuring the environment on UNIX).
- On all systems, you cannot migrate existing OLAP Metadata Catalogs until
after the installation process has completed and the SQL scripts you need
have been created (see Creating or upgrading OLAP Metadata Catalogs).
If you have an existing OLAP Metadata Catalog from an earlier version of DB2 OLAP Integration Server,
you must upgrade it before using the OLAP Metadata Catalog with the current
release of the software.
You cannot upgrade an existing OLAP Metadata Catalog until after you have
completed the installation process. The Essbase Integration Services setup
program installs the scripts that are needed for the upgrade (see Creating or upgrading OLAP Metadata Catalogs).
CAUTION:
If you have installed the sample application from a previous release
of Essbase Integration Services, you should back up your existing sample database,
OLAP Metadata Catalog, and the OLAP models and metaoutlines stored in the
catalog. You can then upgrade your existing catalog to be compatible with
the current release of the software. You cannot, however, store new sample
OLAP models and metaoutlines in your previous catalog.
To upgrade an existing OLAP Metadata Catalog, perform the following tasks:
- Complete the upgrade steps for the existing OLAP Metadata Catalog described
in Creating or upgrading OLAP Metadata Catalogs.
- When connecting to the relational database, make sure to use the same
user name and password that you used when you created the original OLAP Metadata
Catalog. This procedure adds new tables to the OLAP Metadata Catalog without
disturbing the existing information.
CAUTION:
After you upgrade an OLAP Metadata Catalog, you cannot roll back
to the previous release. The new release of OLAP Metadata Catalog is not compatible
with previous releases of DB2 OLAP Integration Server. In addition, do not attempt to use the Version
8.1 OLAP Metadata Catalog with previous releases of the software; doing so
could result in corrupted catalog data.
