The amount of random-access memory (RAM) that you require to run your DB2 server depends on the size of your databases and on the administration tools you will use. For example, if you plan to use the DB2 GUI tools to administer and configure your DB2 databases, the minimum amount of RAM we recommend is 128 MB.
The DB2 GUI tools are a set of administration and configuration tools that include the Command Center, Control Center, and the Data Warehouse Center. Additional GUI tools are available on Windows 32-bit and OS/2 operating systems. These include the Client Configuration Assistant, Event Monitor and Event Analyzer. For more information about DB2 GUI tools and the platforms on which they are available, refer to the Administration Guide.
To run a DB2 Run-Time Client or an DB2 Application Development Client, you need a minimum of 16 MB of RAM. If you are planning to run a DB2 Administration Client, you need a minimum of 32 MB of RAM.
