installation options:
<P

><UL
><LI
>Typical: 460–560 MB. This option installs and
configures most of the DB2 components, using a typical
configuration with default values. This option includes all of the
core features, along with ODBC support, and commonly used tools
such as the Control Center. You can select the "<B
CLASS="command"
>View
Features</B
>" button to see what components get installed
with this option.
</LI
><LI
>Compact: 380–460 MB. This option installs and
configures only the basic DB2 components, with minimal
configuration performed on your computer. With this option you get
the base server and client support, along with Java and SQL
procedure support. Again, you can click
the "<B
CLASS="command"
>View Features</B
>" button for more
information.
</LI
><LI
>Custom: 320–820 MB. This option allows you to install
only those components that you select; and to create and customize
a basic DB2 instance.
</LI

>Make your choice and click "<B
CLASS="command"

of these instructions are based on the Custom installation option).

installations settings in a response file by selecting "<B

option if you plan to install DB2, with these same settings, on other
computers in your environment.</P

browser. If you have a copy of the DB2 Information Center installed
elsewhere on an intranet server, you can choose the "<B

creates a local database that stores task metadata. If you do not have
this task repository, the scheduler will not function. If you want to
create a DB2 tools catalog after you finish the installation, select
the "<B

notify administrators if a database requires attention.
Either create a new contact list that is stored locally, or use an
existing global contact list that resides on a remote DB2 server. Use
an available SMTP server that will accept an unauthenticated SMTP
message for e-mail notifications. You may also choose to skip this
step; DB2 will still record all administration notifications in the
log files. Click "<B
CLASS="command"
>Next</B

>If you specified a new local list for contacts in the previous
step, then in the Specify a contact for health monitor notification, you
can add a name and email address where DB2 Health Center messages will
be sent for any health alerts from DB2 databases.

the installation settings, and then click

While the files are being copied to your computer, you will see two status
bars on the <B

indicating the progress of each individual installation task, and one for
the overall installation progress. When the installation is finished, the
<B

post-installation steps need to be taken, along with a tab (labelled "Log
File") that shows the log file report for the installation. Click
"<B
