Review the descriptions of each upgrade procedure to determine
how to perform your upgrade.
You can have more than one installation, with the
same or different versions, of Rational® Synergy on
a given computer, for client and engine software. Your existing Rational Synergy databases
can run on one or more servers.
On Windows,
you cannot have more than one Rational Synergy Informix® server per computer,
even for different releases of Rational Synergy.
Installing a Rational Synergy 7.2 or later server
on a Windows computer upgrades
any previously existing Rational Synergy servers.
It also disables the use of those servers under the earlier releases.
As a result, there are two ways to upgrade your
databases from earlier releases.
Methods for performing upgrades
Choose from
one of the following upgrade procedures for each server:
- Upgrading a new server
- Create a 7.2 or later server
on a different computer, and then, copy your databases to this new
server, and upgrade them. Databases can be copied to the new server
by using ccmdb pack. Then, use ccmdb unpack.
Perform this procedure when you test Rational Synergy 7.2 or later.
After you have completed testing, use it again when you upgrade production
databases for live use.
- Upgrading an existing server
- Upgrade an existing server to 7.2 or later,
and upgrade all the databases in that server. Installing 7.2 or later using
this procedure immediately performs the server upgrade, and renders
the databases unusable under previous releases. Each database on the
server must be upgraded to 7.2 or later before
it can be used. It is not required to move or copy the databases because
they are already in an upgraded server. Do not use this procedure
while testing Rational Synergy 7.2 or later.
However, you can use it after you have completed testing on a separate
server.
Note: You can use different procedures for different servers.
To
determine which method to use, review the following checklists.
Upgrading an existing server checklist
Use the procedures in the Upgrading an existing server if
all of the following items pertain to you:
- Your operating system is compatible with both your
previous release of Rational Synergy and
Release 7.2 or later.
- You want to keep the same CM administrator user.
- You want to upgrade all your databases on the server
at the same time. All databases can be concurrently offline until
the upgrade is complete.
- You do not want to create an Informix database server. You want to upgrade
your existing server and its databases in place.
Note: You receive some performance benefits if
you choose to create an Informix database
server. Your databases are unpacked, which causes the database indexes
to be rebuilt and the data to be defragmented, This process improves
performance.
Upgrading a new server checklist
Use
the procedures in the Upgrading a new server if any one of the following items pertain to
you:
- You are testing the new release of Rational Synergy.
- You must upgrade to a new operating system that
is not compatible with your previous release of Rational Synergy.
- You want to change the CM administrator user.
- You want to upgrade only some of the databases
on a server at this time, leaving the others accessed through the
previous release.
- You want to move some databases between file systems,
servers, or computers (including from UNIX to Windows, or from Windows to UNIX).
- You want to create an Informix database server.
