Creating a Db2 administration server (DAS)

The Db2 administration server (DAS) is a control point used only to assist with tasks on Db2 database instances.

Before you begin

Important: The Db2 Administration Server (DAS) has been deprecated 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 .

To create a DAS, you must have root user authority on Linux® operating systems or use an account that has the correct authorization to create a service. On Windows, if a specific user is to be identified, create a user with local Administrator authority. Enter db2admin create. If a specific user account is desired, you must use /USER: and /PASSWORD: when issuing the db2admin create command.

About this task

You can have only one DAS in a database server. If one is already created, you need to drop it by issuing db2admin drop.

Typically, the setup program creates a DAS on the instance-owning computer during Db2 database product installation. If, however, the setup program failed to create it, you can manually create a DAS.

Procedure

As an overview of what occurs during the installation process as it relates to DAS, consider the following:

On Windows operating systems:
1. Log on to the computer you want to create the DAS on using an account that has the correct authorization to create a service.
  When creating the DAS, you can optionally provide a user account name and a user password. If valid, the user account name and password identify the owner of the DAS. Do not use the user ID or account name created for the DAS as a user account. Set the password for the account name to Password Never Expires. After you create the DAS, you can establish or modify its ownership by providing a user account name and user password with the db2admin setid command.
On Linux operating systems:
1. Ensure that you have root user authority.
2. At a command prompt, issue the following command from the instance subdirectory in the Db2 installation path:
```
dascrt -u DASUser
```
  DASUser is the user name of the DAS user you created when you were creating users and groups for the Db2 database.
