The disk space required for your product depends on the type of installation you choose and the type of file system you have. The DB2® Setup wizard provides dynamic size estimates based on the components selected during a typical, compact, or custom installation.
Remember to include disk space for required databases, software and communication products.
On Linux® and UNIX® operating systems, 2 GB of free space in the /tmp directory is recommended.
At a minimum, a DB2 database system requires 256 MB of RAM. For a system running just a DB2 product and the DB2 GUI tools, a minimum of 512 MB of RAM is required. However, 1 GB of RAM is recommended for improved performance. These requirements do not include any additional memory requirements for other software that is running on your system.When determining memory requirements, be aware of the following:
For DB2 server products, the self-tuning memory feature simplifies the task of memory configuration by automatically setting values for several memory configuration parameters. When enabled, the memory tuner dynamically distributes available memory resources among several memory consumers including sort, the package cache, the lock list and buffer pools.
