About this task
Two upgrade procedures are presented in
this section.
You can have more than one installation, with
the same or different versions, of Rational Synergy on a given machine,
for client and engine software. Your existing Synergy databases reside
on one or more servers.
On Windows, you cannot
have more than one Rational Synergy Informix server per machine, even
for different releases of Rational Synergy. Installing a Rational
Synergy 7.1 server on a Windows machine 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.
Perform
one of the following steps:
- Create a 7.1 server on a different machine,. Then,
copy your databases to this new server, and upgrade them. Databases
can be copied to the new server using ccmdb backup or ccmdb
pack. Then, use the ccmdb unpack, or ccmdb
dump and ccmdb load, in combination with
a copy of the file system portion of the database. Perform this procedure
when you test Rational Synergy 7.1. After you have completed testing,
use it again when you upgrade production databases for live use.
OR
- Upgrade an existing 6.4, 6.5, or 7.0 server to
7.1, and upgrade all the databases in that server. Installing 7.1
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 7.1 before it can be used. The databases
do not need to be moved or copied because they are already in an upgraded
server. Do not use this procedure while testing Rational Synergy 7.1.
However, you can use it after you have completed testing on a separate
server.
For each server, upgrade the databases on that
server using one of these two procedures. You can use different procedures
for different servers.
Upgrading an Existing
Server" and "Upgrade to a New Server" are outlined in two different
checklists in this section. The following paragraphs explain which
checklist you need to follow.
Existing server
upgrade
Use the procedures in Overview if:
- Your operating system is or will be compatible
with both your previous release of Rational Synergy and Release 7.1, and
- You want to keep the same CM administrator user, and
- 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, and
- 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.
New server upgrade
Use the procedures
in Overview if:
- You are testing the new release of Synergy, or
- You need to upgrade to a new operating system that
is not compatible with your previous release of Rational Synergy, or
- You want to change the CM administrator user, or
- You want to upgrade only some of the databases
on a server at this time, leaving the others accessed through the
previous release, or
- You want to move some databases between file systems,
servers, or machines (including from UNIX to Windows, or from Windows
to UNIX), or
- You want to create an Informix database server.
