Create tables for scheduler on DB2® databases using data definition language (DDL) or structured query language
(SQL) files.
Before you begin
This task requires you to configure a database and make it available. Refer to the Creating
DB2 databases for
schedulers topic for more information.
About this task
To create tables for scheduler on DB2 databases, using data definition language (DDL) or structured query
language (SQL) files, use these steps.
Procedure
- Open a DB2
command-line window.
- Verify that you have administrator rights for the database system.
- Create the table space and schema.
- Analyze the results of your experiences during development and system testing. The size of your database depends on many factors. If possible, distribute table space
containers across different logical disks, and implement an appropriate security policy. Consider
the performance implications of your choices for buffer pools and log file settings.
- Using a text editor, edit the following scripts according to the instruction at the beginning
of each file.
Note: When setting the table prefix, capitalize all characters.
%WAS_HOME%\Scheduler\createTablespaceDB2.ddl, %WAS_HOME%\Scheduler\createSchemaMod1DB2.ddl, %WAS_HOME%\Scheduler\dropSchemaMod1DB2.ddl, and %WAS_HOME%\Scheduler\dropTablespaceDB2.ddl.
- Verify that you are attached to the correct instance. Check the environment variable
DB2INSTANCE.
- To connect to the database, scheddb, for example, and enter the command:
db2 connect to scheddb
- Create the table space. Enter the following command:
db2 -tf createTablespaceDB2.ddl
Verify that the script
output contains no errors. If there were any errors, you can drop the table space using the
following script: dropTablespaceDB2.ddl
- To create the schema (tables and indices), in the DB2 command line processor, enter the command db2 -tf
createSchemaMod1DB2.ddl. Verify that the script output contains no errors. If there were any errors, you can use the
following file to drop the schema:
dropSchemaMod1DB2.ddl
- Verify that the DB2_RR_TO_RS DB2 flag is set to YES to avoid deadlocks. Restart the DB2 instance to activate the change, if
needed.
Results
The DB2 tables
and schema for the scheduler exist.
