db2install.history. If the name already exists, then the DB2 installer renames it
db2install.history.xxxx, where xxxx is 0000-9999, depending on the number of
installations you have on that machine.
Each installation copy has a separate list of history files. If an installation copy is
removed, the history files under this install path will be removed as well. This
copying action is done near the end of the installation and if the program is
stopped or aborted before completion, then the history file will not be created.
On Linux 32-bit, 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. The DB2 Information
Center contains documentation for the DB2 database system and DB2 related
products.
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.
