About the system requirements
InfoSphere Information Server product modules are installed in logical tiers: client tier, engine tier, services tier, and metadata repository tier. A tier is a logical group of components within InfoSphere Information Server and the computers on which those components are installed. For more information about tiers, see Understanding tiers and components.
Before you install the IBM InfoSphere Information Server suite product modules and components, you must ensure that each computer meets the system requirements for the logical tiers that you plan to install on that computer. The easiest way to verify that your computer meets the system requirements is to use one of the following tools:
- Start the Version 8.5 installation program to run the System Requirements Check.
- Use the ISA Lite for InfoSphere Information Server tool to run the System Requirements reports. To access this report, you must download, install, and configure the ISA Lite tool. For more information, see http://www.ibm.com/support/docview.wss?uid=swg24022700.
This document describes the system requirements in detail.
Operating system requirements
The engine tier, services tier, and metadata repository tier are supported on 64-bit AIX operating systems.
The following table specifies the supported AIX operating systems.
| Operating system | Processors | Notes | |
|---|---|---|---|
| AIX 5.3 | RISC POWER5, POWER6, and POWER7 processors | Technology Level 10 SP4 or Technology Level 11 is required. The Asynchronous I/O Extension (AIO) package is required. |
|
| AIX 6.1 | RISC POWER5, POWER6, and POWER7 processors | The Asynchronous I/O Extension (AIO) package is required. |
|
| AIX 7.1 | RISC POWER5, POWER6, and POWER7 processors | The Asynchronous I/O Extension (AIO) package is required. Warning occurs during installation requirements check, but can be ignored. See http://www.ibm.com/support/docview.wss?uid=swg21458229. |
Memory requirements
The minimum amount of memory for installing the InfoSphere Information Server engine tier, services tier, and metadata repository tier is as follows:
- Installation of a single tier on a computer requires 4 GB of memory.
- Installation of more than one tier on the same computer requires 6 GB of memory.
Memory requirements depend on the type of processing, the volume of parallel processing, the size and number of simultaneously running jobs, and the memory requirements of the operating system and other applications (such as relational databases).
Evaluate the following factors to determine the memory requirements for your system:
- Number of InfoSphere Information Server product components on the same server
- Other software on the same server
- Performance requirements
- Size and complexity of your configuration
- Extent of activity and the number of concurrent clients that access your server
Disk space requirements
See the disk space requirements for the engine tier, services tier, and metadata repository tier.
Engine tier disk space requirements
The following table specifies the minimum disk space requirements for the engine tier installation. These disk space requirements are the minimum requirements for installation. Operational requirements are significantly larger than these minimum installation disk space requirements.
| Engine tier component | Minimum disk space | Notes |
|---|---|---|
| Installation | 2 GB | The system temporary directory requires 1 GB of available free space during installation. |
| Product components | 1.7 GB |
Services tier disk space requirements
The following table specifies the minimum disk space requirements for the services tier installation. These disk space requirements are the minimum requirements for installation. Operational requirements are significantly larger than these minimum installation disk space requirements.
| Services tier component | Minimum disk space | Notes |
|---|---|---|
| Installation | 2 GB | The system temporary directory requires 1 GB of available free space during installation. |
| WebSphere Application Server | 2.1 GB | |
| Product components | 1.1 GB |
Metadata repository tier disk space requirements
The following table specifies the minimum disk space requirements for the metadata repository tier installation. These disk space requirements are the minimum requirements for installation. Operational requirements are significantly larger than these minimum installation disk space requirements.
| Metadata repository tier component | Minimum disk space | Notes |
|---|---|---|
| Installation | 2 GB | The system temporary directory requires 1 GB of available free space during installation. |
| DB2 database software | 1 GB | Optionally installed with Version 8.5. |
| Metadata repository database | 1 GB to 2.5 GB | Disk space requirements vary based on your database software. DB2 requires 2.5 GB, Oracle requires 1 GB, and SQL Server requires 1.2 GB. |
| InfoSphere Information Analyzer analysis database | 1.2 GB |
Networking requirements
The client tier, engine tier, services tier, and metadata repository tier must be able to communicate with each other over the network on all ports that are used by the software. The host computer must be able to resolve its host name to an IP address.
Database server requirements
The database server must be installed on the same computer that the services tier is installed on, or on the metadata repository tier computer with high-speed network connectivity to the services tier computer. This requirement might not be met when the computers are not on the same network segment or if a firewall is installed between the two computers.
Note: The Version 8.5 installation program can install a new instance of DB2 Enterprise Server Edition (ESE) Version 9.7, or you can use an existing DB2 ESE Version 9.5 or DB2 ESE Version 9.7 installation.
The following table specifies the database servers that are supported for the metadata repository database and the InfoSphere Information Analyzer analysis database:
| Database server software | Notes | |
|---|---|---|
| Microsoft SQL Server 2005 | Enterprise Edition | |
| Microsoft SQL Server 2008 | Enterprise Edition | |
| Δ | IBM DB2 Enterprise Server Edition Version 9.5 |
Fix Pack 2a or a subsequent fix pack for this version is required. High-availability disaster recovery (HADR) is supported. Partitioned databases are not supported. |
| Δ | IBM DB2 Enterprise Server Edition Version 9.7 |
Fix Pack 3a or a subsequent fix pack for this version is required. Partitioned databases are not supported. |
| Δ | IBM DB2 Version 9.1 for z/OS |
Version 9.1 or a subsequent fix pack for this version is required. |
| Oracle 10g Release 2 | Advanced Security option is not supported. Real Application Clusters (RAC) is supported only for the metadata repository database. Installation on the same subnet as WebSphere Application Server is recommended. |
|
| Oracle 11g Release 2 | Advanced Security option is not supported. Real Application Clusters (RAC) is supported only for the metadata repository database. Installation on the same subnet as WebSphere Application Server is recommended. |
Application server requirements
IBM WebSphere Application Server Network Deployment is required for the services tier.
- The InfoSphere Information Server installation program can install WebSphere Application Server Network Deployment, Version 7.0 fix pack 11 and additional iFixes when it installs InfoSphere Information Server Version 8.5. If you use an existing installation of WebSphere Application Server, you must install the fix pack and additional iFixes.
- The 64-bit version of WebSphere Application Server Network Deployment is supported, however the 32-bit version of WebSphere Application Server is not supported.
The following table specifies the application server requirements.
| Application server software | Notes | |
|---|---|---|
| Δ | WebSphere Application Server Network Deployment, Version 6.1 |
Fix pack 29 or a subsequent fix pack for this version is required. If you use an existing installation of WebSphere Application Server, additional iFixes might also be required. See http://www.ibm.com/support/docview.wss?uid=swg27019072. A supported web server is required. See System requirements for WebSphere Application Server V6.1 on IBM AIX. |
| Δ | WebSphere Application Server Network Deployment, Version 7.0 |
Fix pack 11 or a subsequent fix pack for this version is required. If you use an existing installation of WebSphere Application Server, additional iFixes might also be required. See http://www.ibm.com/support/docview.wss?uid=swg27019072. A supported web server is required. See System Requirements for WebSphere Application Server V7.0 on IBM AIX. |
InfoSphere DataStage and QualityStage requirements

- XL C/C++ for AIX, V9
- XL C/C++ for AIX, V10.1
- XL C/C++ for AIX, V11.1
Compilers on AIX 7.1 require the latest updates (PTFs). See http://www.ibm.com/support/docview.wss?uid=swg21110831.
