Updating the Db2 administration server (Linux and UNIX)

On Linux® and UNIX operating systems, Db2 database products can be installed multiple times on a single machine. There can only be one Db2 Administration Server (DAS), however, and it will be used by all of the Db2 copies. The DAS can be created from any Db2 Copy and will run at the same fix pack level as that Db2 Copy. If you apply a fix pack to that Db2 Copy, you should issue the dasupdt command to update the DAS.

About this task

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 .
You can also use the dasupdt command to move the DAS from one Db2 Copy to another, provided that they are both running the same version of Db2 database system. For example, if there is a Db2 Copy that is running at a more recent fix pack level than all of the other Db2 copies, consider updating the DAS to belong to that Db2 Copy.
Note: If you want to move the DAS to a Db2 Copy running at an earlier fix pack level, you need to specify the -D command parameter.

Procedure

To update the DAS:

  1. Log on to the computer with superuser authority, usually as "root".
  2. Issue the dasupdt command.
    For example: 
    DB2DIR/instance/dasupdt
    where DB2DIR represents the location where the Db2 copy is installed.

Results

Once this command completes, the DAS runs at the new fix pack level of the Db2 copy.

Examples

If the DAS is associated with a Db2 copy that is installed in /opt/ibm/db2/V9.1_01 and Fix Pack 3 is installed on the Db2 database products in that Db2 copy, the following command will update the DAS to Fix Pack 3 
/opt/ibm/db2/V9.1_01/instance/dasupdt
If the DAS is associated with a Db2 copy that has Fix Pack 3 installed, and there is another Db2 copy that has Fix Pack 2 installed (located in /opt/ibm/db2/V9.1_02 ), the following command will downgrade the DAS to Fix Pack 2: 
/opt/ibm/db2/V9.1_02/instance/dasupdt -D
