Creating and populating the database for DB2 for z/OS for the Dynamic Workload Console

Instructions for creating and populating the database for DB2 for z/OS for Dynamic Workload Console

Before you begin

Ensure a DB2 for z/OS database is installed.

About this task

Creating and populating the Dynamic Workload Console database

You can perform a typical database procedure, as described in the following scenarios, or you can customize the database parameters, as described in FAQ - Database customizations.

DB2 for z/OS requires a specific procedure in which you first create the database and then create and populate the database tables. To simplify the database creation, a sample JCL named EQQINDWC is provided with Package HWAZ_950_APAR_HC00001 containing the specifics for creating the Dynamic Workload Console database. The database administrator can use this file to create the database. After the database has been created, you can proceed to create and populate the database tables.

You can run the configureDb command specifying a typical set of parameters. In this case, default values are used for all remaining parameters.

For more information about all parameters and supported values of the configureDb command, see Database configuration - configureDB script. Default values are stored in the configureDb.properties file, located in image_location.

If you need to modify any of the default values, edit the configureDbdatabase_vendor>.properties file, but do not modify the configureDbdatabase_vendor>.template file located in the same path.

To create and populate the Dynamic Workload Console database and schema for DB2 for z/OS, perform the following steps:

Procedure

From the SEQQSAMP library, edit the EQQINDWC sample JCL as required.

Note: The EQQINDWC sample JCL is provided with the Package HWAZ_950_APAR_HC00001. If you did not install this APAR, create a JCL named EQQINDWC that looks like the following example:

Instruct the DB2 for z/OS administrator to create the DB2 for z/OS user on the server hosting the DB2 for z/OS database. You will then specify this user with the dbuser parameter when creating and populating the database with the configureDb command on the Dynamic Workload Console. When you run the configureDb command, this user is automatically granted access to the Dynamic Workload Console tables on the database server.
On the server where you plan to install the Dynamic Workload Console, browse to the directory where you extracted the Dynamic Workload Console image.
Type the following command to create and populate the Dynamic Workload Console database tables with typical settings:
On Windows operating systems
```
cscript configureDb.vbs --rdbmstype DB2Z --dbhostname DB_hostname
--dbport db_port --dbname db_name --dbuser db_user
--dbadminuser DB_admin_user --dbadminuserpw DB_admin_pwd
--zlocationname zOS_location_containing_db --zbufferpoolname buffer_pool_in_zOS_location
```
On UNIX operating systems
```
./configureDb.sh --rdbmstype DB2Z --dbhostname DB_hostname
--dbport db_port --dbname db_name --dbuser db_user
--dbadminuser DB_admin_user --dbadminuserpw DB_admin_pwd
--zlocationname zOS_location_containing_db --zbufferpoolname buffer_pool_in_zOS_location
```
On z/OS operating systems
```
./configureDb.sh --rdbmstype DB2Z --dbhostname DB_hostname
--dbport db_port --dbname db_name --dbuser db_user
--dbadminuser DB_admin_user --dbadminuserpw DB_admin_pwd
--zlocationname zOS_location_containing_db --zbufferpoolname buffer_pool_in_zOS_location
```
where:

--rdbmstype

The database vendor.

--dbhostname db_hostname

The host name or IP address of database server.

--dbport db_port

The port of the database server.

--dbname db_name

The name of the Dynamic Workload Console database.

--dbuser db_user

The database user you must create before running the configureDb command. When you run the configureDb command, this user is automatically granted access to the HCL Workload Automation tables on the database server.

--dbadminuser db_admin_user

The database administrator user that creates the Dynamic Workload Console schema objects on the database server.

--dbadminuserpw db_admin_password

The password of the DB administrator user that creates the Dynamic Workload Console schema objects on the database server.

--zlocationname zos_location_containing_db

The name of an already existing location in the z/OS environment that will contain the new database. The default value is LOC1.

--zbufferpoolname buffer_pool_in zos_location

The name of an already existing buffer pool created in the location specified by -zlocationname. The default value is BP32K.
Note: The following parameters specified with the configureDb command are also required when installing the Dynamic Workload Console and their values must be the same:
- --rdbmstype
- --dbhostname
- --dbport
- --dbname
- --dbuser
- --zlocationname

Results

You have now successfully created and populated the Dynamic Workload Console database.

For more information about all parameters and supported values of the configureDb command, see Database configuration - configureDB script.

What to do next

You can now proceed to Installing the Dynamic Workload Console.
