Db2 Administration Server

The Db2 Administration Server (DAS) is a control point used only to assist with tasks on Db2 database instances. You must have a running DAS if you want to use available tools like the Replication Center or the Development Center.

Important: The Db2 Administration Server (DAS) has been deprecated in Version 9.7 and might be removed in a future release. The DAS is not supported in Db2 pureScale® environments. Use software programs that use the Secure Shell protocol for remote administration. For more information, see Db2 administration server (DAS) has been deprecated .

DAS assists when working on the following administration tasks:

  • Enabling remote administration of Db2 database instances.
  • Providing the facility for job management, including the ability to schedule the running of both Db2 database manager and operating system command scripts. These command scripts are user-defined.
  • Providing a means for discovering information about the configuration of Db2 instances, databases, and other Db2 administration servers in conjunction with the Db2 Discovery utility. This information is used to simplify and automate the configuration of client connections to Db2 databases.

You can only have one DAS in a database server. If one is already created, you need to drop it by issuing db2admin drop. DAS is configured during installation to start when the operating system is booted.

DAS is used to perform remote tasks on the server system and the host system on behalf of a client request from any of the available tools.

The DAS is available on all supported Windows and UNIX operating systems as well as the zSeries (OS/390® and z/OS® only) platforms. The DAS on zSeries is used to support the Development Center and Replication Center in administrative tasks.

The Db2 administration server on zSeries (OS/390 and z/OS only), will be packaged and delivered as part of the Db2 Management clients feature of the Db2 system. Products that need DAS, like the Replication Center, and Development Center, require the installation of the DAS function.
