Recreating database tables from the exported table data definition language

When the WebSphere Application Server deployment tooling deploys an EJB jar file containing container-managed persistence (CMP) enterprise beans, it selects the target database and creates a corresponding Table.ddl file. This file contains the SQL statement necessary to generate the database table for your CMP beans.

About this task

The following steps demonstrate the process for creating tables in DB2.

Procedure

  1. Extract the Table.ddl file from your CMP enterprise bean JAR file and save it on your database server.
    • Save the file to a working directory, such as C:\temp, on your DB2 machine.
  2. Run the Table.ddl file.
    • Run the command C:\temp>db2cmd, replacing C:\temp with your chosen directory. A DB2 command window is displayed, in which you enter the following commands (replacing C:\temp with your chosen directory):
      1. C:\temp>db2 connect to your_db_name
      2. C:\temp>db2 -tf Table.ddl //This command runs and creates tables for your CMP enterprise bean.
      3. C:\temp>db2 disconnect all
      [AIX] [HP-UX] [Solaris] Note: If you run DB2 on supported UNIX systems, use these same commands. Run them from a user with permissions for DB2, rather than from a DB2 command window.

Results

The database tables are created.
