Hardware and software requirements

An overview of the requirements follows. To learn more about the system requirements for the Db2 Recovery Expert product, see the System requirements for IBM Db2 Recovery Expert for Linux, UNIX, and Windows document.

Hardware requirements overview

Requirements for the Db2 Recovery Expert server include the following:

• Operating system platform: The Db2 Recovery Expert server software can be installed on any supported Linux, UNIX, or Windows operating system platform. Optionally, it can be installed on the same system as an existing Db2 database server.
• Storage and memory requirements:
  • A minimum of 1 GB of disk space should be available on the file system where the Db2 Recovery Expert server components will be installed.
  • Additional space may be required for storing activity logs and intermediate result data that is made available to the Db2 Recovery Expert browser clients. The amount will depend on the type of product activity.
  • At least 1 GB of temporary space should be available during installation on the system temporary file system (the /tmp file system on Linux/UNIX systems, or the location specified by the TEMP variable on Windows systems).
  • A minimum of 2 GB of available memory is recommended.
• Processor requirements: Sufficient processing power should be available to support the demands of any concurrent Db2 Recovery Expert browser client sessions.

Requirements for the Db2 Recovery Expert browser client include the following:

• Operating system platform: No product software needs to be installed to run the Db2 Recovery Expert browser client application. The browser client application runs in a supported web browser on any of the supported operating system platforms. It accesses the application software on the system where the Db2 Recovery Expert server is installed.
• Storage and memory requirements:
  • A reasonable amount of local disk space should be available for the user to save Log Analysis reports, SQL output, or other result data.
  • No local disk storage is required for product intermediate or result data because all processing occurs remotely on the Db2 Recovery Expert server or on the Db2 database server systems.
  • A minimum of 2 GB of available memory is recommended.
• Display recommendations: The minimum recommended screen resolution for using the browser client is 1024 x 768 (width x height). To increase the viewable area, adjust the following settings:

  • Disable search bars and Toolbars in the browser.
  • Decrease the font size in the browser.
  • Decrease the zoom setting in the browser.
  • Increase the resolution of the display.

Requirements for the Db2 Recovery Expert database server components include the following:

• Operating system platform: The Db2 Recovery Expert database server components must be installed on any supported Linux, UNIX, or Windows operating system platform where you want to use Db2 Recovery Expert to access Db2 databases.
• Storage and memory requirements:
  • A minimum of 1 GB of disk space should be available on the file system where the Db2 Recovery Expert database server components will be installed.
  • Additional space will be required for storing intermediate working data while the product is running, and for storing result data into the product datastore repository. For more information about disk space requirements, see Operational prerequisites.
  • A minimum of 2 GB of memory should be available for running Db2 Recovery Expert processes on the Db2 database server systems.

Requirements for the Db2 Recovery Expert command line processor (CLP) include the following:

• Operating system platform: The Db2 Recovery Expert CLP can be installed on any supported Linux, UNIX, or Windows operating system platform where you want to use the command line feature.
• Storage and memory requirements:
  • A minimum of 500 MB of disk space should be available on the file system where the CLP will be installed.
  • At least 500 MB of temporary space should be available during the installation on the system temporary file system (the /tmp file system on Linux/UNIX systems, or the location specified by the TEMP variable on Windows systems).
  • A minimum of 2 GB of available memory is recommended.

Requirements for the Db2 Recovery Expert License Activation Kit include the following:

• Operating system platform: The Db2 Recovery Expert License Activation Kit can be installed on any supported Linux, UNIX, or Windows operating system platform where the Db2 Recovery Expert server has been installed.
• Storage requirements:
  • Only a small amount of disk space is used on the file system where the Db2 Recovery Expert database server components were installed.
  • At least 500 MB of temporary space should be available during the installation on the system temporary file system (the /tmp file system on Linux/UNIX systems, or the location specified by the TEMP variable on Windows systems).

Software requirements overview

The software requirements for running the Db2 Recovery Expert server and the Db2 Recovery Expert database server components vary depending on the operating system, platform, and other environmental considerations.
