on the number of options you have installed. There are three options to install IBM DB2 9, which are ESE, CLIENT, and RTCL. Generally, 2 GB space is sufficient if you install all three options. On AIX, the basic DB2 products are installed in the/opt/IBM/DB2/V9.1 directory by default.
Memory Requirements
The DB2 database system requires at least 256 mb ram. For a system that only runs the DB2 and DB2 GUI tools, at least 512 mb ram is required. However
