Installing IBM data server clients (Linux and UNIX)

To install an IBM® data server client on Linux® or UNIX operating systems, perform the following instructions. The instructions apply to the IBM Data Server Client and the IBM Data Server Runtime Client.

Before you begin

  • If the machine already has an earlier version of a client installed, review the topics that cover upgrading.
  • Determine whether the IBM Data Server Client or the IBM Data Server Runtime Client best suits your needs.
  • Locate a DVD or other installation image that you need. To download an image,
    1. Go to the IBM Support Fix Central website (
    2. From the Product Group list, select Information Management.
    3. From the Information Management product list, select IBM Data Server Client Packages.
    4. From the Installation Version list, select a particular version or all versions.
    5. From the Platform list, select a particular platform or all platforms, and click Continue.
  • Ensure that your system meets all memory, disk space, and installation requirements. The installation program checks the disk space and basic system requirements and notifies you if there is a problem.
  • If you are installing an IBM data server client on a Linux operating system, you must update your kernel configuration parameters.
  • If you are installing your IBM data server client on an NFS-mounted file system, you must verify that Network File System (NFS) is running.

About this task

If the machine already has a data server product installed, it is not necessary to install a client because the data server provides all the capabilities of the IBM Data Server Client software.


To install any IBM data server client on a Linux or UNIX operating system:

  1. Insert and mount the appropriate DVD.
  2. In the directory where the DVD is mounted, start the setup wizard by entering ./db2setup .
  3. When the Db2Launchpad opens, choose Install a Product.
  4. Select the client that you want to install.
  5. Follow the prompts in the setup wizard. Help is available in the wizard to guide you through the remaining steps.


When installation is complete, the IBM data server client is installed in the following directories by default:
Linux operating systems
UNIX operating systems

What to do next

After installing your IBM data server client, configure it to access a remote data server.

National language installations

You can run the setup wizard in a language other than the default system language by manually invoking the setup wizard and specifying a language code. For example, the ./db2setup -i fr command runs the setup wizard in French. However, the setup wizard fields do not accept non-English characters.

Installing on a machine that has an existing Db2® Version 11.1 client

The default directory name for the first copy is V11.5. For additional copies on a particular machine, the default directory name is V11.5_nn, where nn refers to the number of copies that are installed minus one. For example, the second installation has a default directory name of V11.5_01.

Installing the IBM Data Server Client or IBM Data Server Runtime Client on a system that already has a Db2 Version 11.1 client preserves that copy and installs an additional Db2 Version 11.1 or higher copy. For information about upgrading client instances, see the upgrading topics.
