The following list describes DB2 installation
methods.
- DB2 Setup wizard
- The DB2 Setup wizard is
a GUI installer available on Linux, UNIX,
and Windows operating systems.
The DB2 Setup wizard provides
an easy-to-use interface for installing DB2 products
and for performing initial setup and configuration tasks.
The DB2 Setup wizard can also create DB2 instances and response files
that can be used to duplicate this installation on other machines.
Note: For
non-root installations on Linux and UNIX platforms,
only one DB2 instance can exist.
The DB2 Setup wizard automatically
creates the non-root instance.
On Linux and UNIX platforms, an X server is required
to display the DB2 Setup wizard.
- Response file installation
- A response file is a text file that contains setup and configuration
values. The file is read by the DB2 setup
program and the installation is performed according to the values
that have been specified.
A response file installation is also
referred to as a silent installation.
Another advantage to response
files is that they provide access to parameters that cannot be set
using the DB2 Setup wizard.
On Linux and UNIX operating systems, if you embed the DB2 installation image in your
own application, it is possible for your application to receive installation
progress information and prompts from the installer in computer-readable
form. This behavior is controlled by the INTERACTIVE response
file keyword.
There are a number of ways to create a response
file:
- Using the response file generator
- You can use the response file generator to create a response file
that replicates an existing installation. For example, you might install
an IBM® data server client,
fully configure the client, then generate a response file to replicate
the installation and configuration of the client to other computers.
- Using the DB2 Setup wizard
- The DB2 Setup wizard can
create a response file based on the selections you make as you proceed
through the DB2 Setup wizard.
Your selections are recorded in a response file that you can save
to a location on your system. If you select a partitioned database
installation, two response files will be generated, one for the instance-owning
computer and one for participating computers.
One benefit of this
installation method is that you can create a response file without
performing an installation. This feature can be useful to capture
the options required to install the DB2 product.
The response file can be used at a later time to install the DB2 product according to the exact
options you specified.
You can export a client or server profile
with the db2cfexp command to save your client or
server configuration, and then easily import the profile using the db2cfimp command.
A client or server profile exported with the db2cfexp command
can also be imported during a response file installation using the
CLIENT_IMPORT_PROFILE keyword.
You should export the client
or server profile after performing the installation and cataloging
any data sources.
- Customizing the sample response files that are provided for each DB2 product
- An alternative to using the response file generator or the DB2 Setup wizard to create a response
file is to manually modify a sample response file. Sample response
files are provided on the DB2 product
DVD. The sample response files provide details about all the valid
keywords for each product.
- db2_install command (Linux and UNIX platforms
only)
- The db2_install command installs all components
for the DB2 product you specify
with the English interface support. You can select additional languages
to support with the -L parameter. You cannot select
or deselect components.
Although the db2_install command
installs all components for the DB2 product
you specify, it does not perform user and group creation, instance
creation, or configuration. This method of installation might be preferred
in cases where configuration is to be done after installation. To
configure your DB2 product while
installing it, consider using the DB2 Setup
wizard.
On Linux and UNIX operating systems, if you
embed the DB2 installation
image in your own application, it is possible for your application
to receive installation progress information and prompts from the
installer in computer-readable form.
This installation methods
requires manual configuration after the product files are deployed.
- Payload file deployment (Linux and UNIX only)
- This method is an advanced installation method that is not recommended
for most users. It requires the user to physically install payload
files. A payload file is a compressed tarball that contains all of
the files and metadata for an installable component.
This installation
methods requires manual configuration after the product files are
deployed.
Note: DB2 product installations are no
longer operating system packages on Linux and UNIX platforms. As a result, you
can no longer use operating system commands for installation. Any
existing scripts that you use to interface and query with DB2 installations must change.
