About this task
When migrating an existing system
to Telecom Web Services Server version 7.1,
the program code is updated independently of your configuration data.
Not all of the existing configuration data will necessarily apply
to the new version 7.1 system.
However, wherever possible, your existing configuration data can be
brought forward to the new version level.
The following
steps outline the process for migrating a non-production, or test,
system to version 7.1.
- Verify the hardware topology. For
details, refer to the topic Standard configurations for Telecom
Web Services Server.
In TWSS version 7.1 it
is recommended–but no longer required–that you run the Access Gateway in
a separate cluster from the other product components. As a result,
you may choose to modify your clustering topology to use TWSS Version 7.1.
- Verify that the appropriate version of WebSphere® Application Server and
all other prerequisite software is installed. For details,
refer to the topic Software requirements.
- Stop all application servers, node agents, and
deployment managers. For details, refer to the topic Stopping
and starting the server.
- Remove applications and uninstall the program
code for the old version of Telecom Web Services Server. For detailed instructions, refer to the Removing Telecom
Web Services Server section of the information center for the
product version you are replacing.
The First Steps script will
migrate data only from a consolidated or shared database, not from
a distributed database. Verify that the Service Policy Manager tables,
CONFIGPROPERTIES and CFGPROPERTIES (if Parlay is used), tables exist
in the primary database before proceeding.
- Run the TWSS base installer to install version 7.1 program
code on the new deployment manager, or on the single server instance
if there is no deployment manager. For details, see the Installing
Telecom Web Services Server base components section of this
information center.
- Run the TWSS services installer to install version 7.1 program
code for the Web service implementations on
the new deployment manager, or on the single server instance if there
is no deployment manager. For details, see the Installing
Telecom Web Services Server services section of this information
center.
- Start the deployment managers and all node agents. For details, refer to the topic Stopping and starting
the server.
- Run the First Steps script to
configure each deployment manager or server on which you installed
the TWSS program code. The First Steps script has
a Migrate option that enables you to migrate old
policies and configuration data.
In a distributed database configuration
where there is one database per cluster, run the First Steps script,
using the Migrate option, on each cluster. In each
case, make sure that the database parameters refer to the database
that pertains to that cluster–for example, AGDB for the Access Gateway cluster
or SPMDB for the Service Policy Manager cluster.
In
a distributed database configuration where there is more than one
database per cluster, create a new temporary database and run the First Steps script on
each cluster. You will need to manually configure the data sources
in the WebSphere Integrated Solutions Console to
point to the right database after the First Steps is completed.
For
details, refer to the topic Migrating data in a distributed
database configuration.
- Create additional data sources, as necessary,
and update the necessary JNDI bindings to the respective data sources.
- Test the database connection and start the
clusters or server instances.
