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 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 .
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:
- Log on to the computer with superuser authority, usually
as "root".
- 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
