DB2 V9.1 Installation and Configuration Guide for AIX

DB2 V9.1 for AIX Installation and Configuration Guide

1. System Requirements Overview

1.1 Hardware Requirements

Before installing DB2 V9.1 for AIX, ensure the following minimum hardware specifications are met:

• Physical Memory: Minimum 256MB; however, 1GB is recommended for optimal performance.
• Disk Space: At least 500MB for DB2 and its GUI tools installation, excluding database files.

For DB2 and GUI tools, 512MB is the minimum, with a recommended 1GB for better performance. Consider additional memory for other software running on the system.

Memory Considerations:

- DB2 Client Support: Five concurrent client connections require the specified memory. For every additional five connections, add 16MB of memory.

- Database System Scale and Complexity: Memory requirements will vary based on database size, complexity, and the number of connected clients.

- Swap Space: For Linux, swap space should be twice the physical memory.

1.2 Software Requirements

For DB2 V9.1, the following AIX operating system requirements must be met:

• AIX Version: Supported versions are 5.2 (TL 5200-08, SP 5200-08-02) and 5.3 (TL 5300-04, SP 5300-04-02).
• C++ Runtime Environment: Minimum xlC.rte 8.0.0.4 and xlC.aix50.rte 8.0.0.8.

Additional Setup:

• Switch to 64-bit kernel using the following commands as root:

  # ln -sf /usr/lib/boot/unix_64/unix

  # ln -sf /usr/lib/boot/unix_64 /usr/lib/boot/unix

  # bosboot -a

  # shutdown -Fr

• Install the IBM C++ runtime environment component for AIX (available from the AIX support site).

• Supported browsers for online help and first steps (db2fs): Mozilla 1.4+, Firefox 1.0+, or Netscape 7.0+.
