DB2 10.5 for Linux, UNIX, and Windows

Upgrading the DB2 Administration Server (DAS)

Upgrading your DB2® Administration Server (DAS) is only necessary to keep your existing DAS configuration.

Otherwise, you can drop your existing DAS and create a new DAS in DB2 Version 10.5.

Start using IBM® Data Studio and IBM Optim™ tools. For a mapping between these recommended tools and Control Center tools, see Table of recommended tools versus Control Center tools.

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 .

Before you begin

Ensure that you have SYSADM authority, and root access on Linux and UNIX operating systems or Local Administrator authority on Windows operating systems.

Restrictions

You can have only one DAS per computer.

Procedure

To upgrade the DAS:

Log on to the DB2 server as root on Linux and UNIX operating systems or Local Administrator authority on Windows.
Upgrade your existing DAS by running the dasmigr command:
Operating system Command syntax

Linux and UNIX $DB2DIR/instance/dasmigr

Windows %DB2PATH%\bin\dasmigr

Where DB2DIR and DB2PATH indicate the location that you specified during DB2 Version 10.5 installation.

If the DAS is running, the dasmigr command stops the DAS before upgrade and starts the DAS after upgrade.
If you created a tools catalog database and want to use your existing scripts and schedules in DB2 Version 10.5, perform the following steps:
- Upgrade the instance that owns the tools catalog database.
- Upgrade the tools catalog database.
- Verify that the DAS is configured to access the upgraded tools catalog database by running the GET ADMIN CFG command to display the current configuration settings for the tools catalog database:
```
   db2 GET ADMIN CFG

            Admin Server Configuration
    ...
    Tools Catalog Database                    (TOOLSCAT_DB) = toolsdb
    Tools Catalog Database Instance         (TOOLSCAT_INST) = db2inst1
    Tools Catalog Database Schema         (TOOLSCAT_SCHEMA) = cc
    Scheduler User ID                                       =
```
  Use the UPDATE ADMIN CFG command if you must change any configuration settings for the tools catalog database.
You should upgrade your tools catalog whether you decide to upgrade your DAS or not.
If you do not upgrade or do not have a tools catalog database, you can create one in a DB2Version 10.5 instance to use the task scheduling capability.

Operating system	Command syntax
Linux and UNIX	`$DB2DIR/instance/dasmigr`
Windows	`%DB2PATH%\bin\dasmigr`

Results

You can now use the DAS to administer DB2 Version 10.5 instances, as well as pre-DB2 Version 10.5 instances.
