Creating a DB2 database on Windows

Use the mqsicreatedb command to create a DB2 or Derby database for the broker. Alternatively, you can use the DB2 Control Center to create a DB2 database. If you prefer, you can use any other method supported by DB2 (including command line or batch files); refer to the DB2 documentation for details of how to do this.

When you create a broker, you specify the user ID and password that are used to connect to the database. The user ID must be known to the database and must own the tables that are being accessed. When you create the database, ensure that you create them for the right user ID. DB2 authenticates the user ID using operating system user management, you do not have to define the user ID to DB2 itself.

  1. If you want to create a database with the mqsicreatedb command, enter the command at the command line, specifying the appropriate parameters. You must provide a userID and password known to DB2. Indicate whether you want to create a DB2 database, or a Derby database. For more information about these and other parameters, refer to the mqsicreatedb command.

    If you want to use the Control Center instead of the mqsicreatedb command, complete step 2.

  2. Start the DB2 Control Center. For each database you want to create:
    1. Expand All Systems in the object tree in the DB2 Control Center until you find Databases. Right-click Databases and click Create Database > Standard.
    2. Enter a name and alias for your database. If you have a naming convention for databases, choose a compatible name. The alias name can be the same as the database name. Database names are limited to eight characters. For example, enter WBRKBKDB.
    3. Click Done.
  3. You must increase the database heap size to ensure it is sufficient for the broker. This task is described in Customizing DB2 databases.
  4. When you have completed these steps for every database you have created, click OK.

If you use the DB2 command line to create the databases, you must bind the db2cli package to the database. You do not have to do this if you used the DB2 Control Center wizard, the mqsicreatedb command, or if you created the broker with the Default Configuration wizard.

  1. Open a DB2 Command Line Processor window.
  2. Connect to the broker database:
    db2cmd db2 CONNECT to <YourBrokerDatabaseName>
  3. Enter the following commands, where c:\ is the drive on which you installed DB2. You must enter your full DB2 installation path; do not use spaces or quotes.
    db2 bind C:\SQLLIB\BND\@db2ubind.lst GRANT PUBLIC 
    db2 bind C:\SQLLIB\BND\@db2cli.lst GRANT PUBLIC 
  4. Repeat the previous two steps for every broker database.
