You can configure DB2® for z/OS® subsystems for use with the
no-charge tuning features by submitting a JCL job.
Before you begin
Ensure that the IBM Data Studio full client, Version 3.1.1
is installed on a workstation that you have access to.
About this task
If your subsystem was configured
for the no-charge tuning features that were in IBM® Data Studio full client or administration
client, Version 3.1, then you do not need to follow the steps in this
procedure.
Procedure
Perform the following steps on the DB2 for z/OS subsystem
to configure it for tuning SQL statements:
- Upload the required JCL job files and DBRMs to the subsystem
from the client system.
The JCL files and DBRMs are
located inside the installation directory for the IBM Data Studio full client.
- If you installed the IBM Data
Studio full client on a Windows system,
the JCL is in the installation_directory\QueryTunerServerConfig\no_charge_features\ZOS\version_number_and_mode directory.
- If you installed the IBM Data
Studio full client on a Linux system,
the JCL is in the .installation_directory/QueryTunerServerConfig/no_charge_features/ZOS/version_number_and_mode directory.
Upload the JCL files in ASCII format and the DBRMs in
binary format.

- If your subsystem was configured for earlier versions of IBM Data Studio, and before configuring
for version 3.1.1 you want to drop both the data objects from those
earlier versions and the data in those objects, drop the following
databases.
Important: This step is not required.
Follow it only if you are sure that you want to delete the data that
is in these databases.
Option |
Description |
If your subsystem is configured for versions 2.2.1 or 2.2.1.1: |
Drop databases DB2OSC, DSNOSCDB, and AOCOEDB. |
If your subsystem is configured for versions that are earlier
than 2.2.1: |
Drop databases DB2OSC, DSNOSCDB, and DB2OE. |
- If your subsystem was configured for IBM Optimization Service Center, and before configuring
for version 3.1.1 you want to drop both the data objects from those
earlier versions and the data in those objects, drop databases DB2OSC
and DSNOSCDB.
Important: This step is not required.
Follow it only if you are sure that you want to delete the data that
is in these databases.
- Create the tables for Version 3.1.1.
On the subsystem, modify the corresponding AOCDDL JCL job file to
conform to your environment, then submit the job. The following
table lists the AOCDDL JCL job files for each environment.
