setup program for that language. Online help is available to guide you through

click Cancel at any time to end the installation.
Your
DB2 product will be installed, by default, in the x:\Program
Files\IBM\sqllib directory, where x: represent the drive letter of the drive where
you have installed your DB2 product.
If you are installing on a system where this directory is already being used, the
DB2 product installation path will have _xx added to it, where _xx are digits,
starting at 01 and increasing depending on how many DB2 copies you have
installed.
You can also specify your own DB2 product installation path.
For information on errors encountered during installation, review the installation
log file located in the My Documents\DB2LOG\ directory. The log file uses the
following format: DB2-ProductAbrrev-DateTime.log, for example, DB2-ESE-Tue Apr
04 17_04_45 2006.log.
If you want your DB2 product to have access to DB2 documentation either on your
local computer or on another computer on your network, then you must install the
DB2 Information Center. TheDB2 Information Center contains documentation for
the DB2 database system and DB2 related products. By default, DB2 information
will be accessed from the web if the DB2 Information Center is not locally
installed.
DB2 Express memory limits and the DATABASE_MEMORY configuration parameter:
If you are installing DB2 Express Edition or DB2 Express-C Edition on a system
that has more memory than the maximum memory limit of 4GB, as outlined in the
terms and conditions of the product, you need to explicitly set the DATABASE_MEMORY
configuration parameter to 4GB or less, so that the Self Tuning Memory Manager
will work within your licensed memory limits.
Note: If you have more than one database on that server, the sum of all database
memory usage cannot exceed 4GB.
You can use the Control Center or the UPDATE DATABASE CONFIGURATION
command to make this change. For example, to set the DATABASE_MEMORY limit to
4GB, enter the following command:
DB2 UPDATE DATABASE CONFIGURATION using DATABASE_MEMORY 1000000 IMMEDIATE;
CONNECT RESET;
Also, when using the Configuration Advisor to assist you in configuring the
performance of your database, you need to set the Target Memory on the Server
page to a percentage of your total system memory that will ensure you stay under
the 4GB memory limit.
