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 top 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.
