Creating a DB2 administration server (DAS) - IBM DB2 9.7 for Linux, UNIX, and Windows

The DB2® administration server (DAS) provides support services for DB2 tools such as the Control Center and the Configuration Assistant.

Before you begin

To create a DAS, you must have root user authority on Linux operating systems or using 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 db2admin create.

About this task

You can only have 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 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: 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 will 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 install 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.
