The DB2 Administration Server (DAS) is a special DB2® administration service used to support the GUI tools. The DAS assists the administration tools in local and remote administration, job management and notification. You must have the DAS running if you want to use the DB2 graphical tools.
You can have only one DAS on a computer. During installation, the DAS is configured to start when the operating system is started. If you want to upgrade or update the DAS after installing your DB2 product, see the following commands:
It is recommended that the user ID or the user name have SYSADM authority on each of the computers within the environment so that it can start or stop other instances if required.
In a Network Information Services (NIS) environment, users and groups are remotely managed from an NIS server. Users and groups that you want to use with your DB2 product must exist on the NIS server prior to installation. The DB2 Setup wizard cannot create users or groups in an NIS environment.
To create a new user ID to be the DAS user ID, click New user and provide the required information for the instance-owning user.
The User name you specify must be a valid DB2 user ID. Valid DB2 user IDs:
A UID is a number that uniquely identifies a user. If you want a specific UID to be used, type it in the UID field. Otherwise, select Use default UID to use a system-generated UID.
The Group name you type can be an existing group you have defined, or a new group that will be created if it does not exist. The group must be the primary group of the user.
A GID is a number that uniquely identifies a group. If you are creating a new group and you want a specific GID to be used, type it in the GID field. Otherwise, select Use default GID to use a system-generated GID. If the group already exists, then the GID field will be filled and Use default GID will be disabled.
The Password you specify must contain 1 to 8 characters.
Confirm the password by typing it again in the Confirm password field.
The Home directory is used for storing all information that pertains to the DAS.
You cannot change the location of the directory once it is created.
You can type a valid new directory or click [...] to select an existing directory, although permission problems could arise if an existing directory is used.
The DB2 Setup wizard will check the user ID, home directory and password for validity. The user ID and password are stored in the operating system security files.
Click Existing user to use an existing user ID. You can type a valid User name or click [...] to select an existing user name.
