Chapter 1. Installation prerequisites

Disk and memory requirements

Disk requirements:

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.

On Windows®, you might require significantly more space on FAT (File Allocation Table) drives with large cluster sizes than with NTFS (New Technology File System) drives.

Remember to include disk space for required software and communication products.

Memory requirements:

At a minimum, a DB2 database system requires 256 MB of RAM. For a system running just DB2 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:

vFor DB2 client support, these memory requirements are for a base of five concurrent client connections. You will need an additional 16 MB of RAM per five client connections.

vMemory requirements are affected by the size and complexity of your database system, as well as by the extent of database activity and the number of clients accessing your system.

In DB2 Version 9, the new 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.

vOn Linux, SWAP space at least twice as large as RAM is recommended.

Getting started with database authorities

Authorities provide a way both to group privileges and to control maintenance and utility operations for instances, databases, and database objects. Users can have administrative authorities that give full privileges on a set of database objects, or they can have system authorities that give full privileges on managing the system but do not allow access to the data.
