To create the various forms of the sample databases, use a single command procedure with Oracle Rdb. By default, the command procedure builds the single-file personnel database using SQL data definitions. Use the following command to build this database: $ @RDM$DEMO:PERSONNEL You can specify parameters when you invoke the command procedure to create alternative versions of the sample databases. The following shows the format of the command you enter to create a sample database: $ @RDM$DEMO:PERSONNEL interface-lang database-form reposit multischema dir The parameters specify the following choices: 1. Interface-lang: Enter SQL. Specifies SQL as the data definition language. SQL is the default. There are slight differences between the SQL definitions of PERSONNEL and MF_PERSONNEL. 2. Database-form: Enter S or M. Specifies the creation of either a single-file (S) or multifile (M) database. A single-file database is the default. 3. Reposit: Enter CDD or NOCDD. Specifies whether or not to store data definitions in the repository. The default is not to store data definitions in the repository. 4. Multischema: Enter MSDB or omit parameter. Specifies the creation of a multischema database, CORPORATE_ DATA. Note that for the first three parameters you must specify the SQL interface, the single-file database form, and that data definitions not be stored in the repository. The following example demonstrates how to create the multischema database: $ @RDM$DEMO:PERSONNEL SQL S NOCDD MSDB 5. Dir: Enter a directory specification where you want the database created. If you do not specify this parameter, this procedure will prompt you for a directory specification. If you do not provide a directory specification at the prompt, your default directory will be used. If you run this procedure in batch and this parameter is empty, your default directory will be used. To specify the second, third, fourth, or fifth parameters, you must include any previous parameters. You can use uppercase or lowercase to specify the parameters. For example, to build the the multifile version using SQL data definitions and storing the data definitions in the repository, enter the following command: $ @RDM$DEMO:PERSONNEL SQL M CDD When you build the single-file personnel database, the command procedure builds a database called PERSONNEL.RDB, regardless of the interface language used. When you build the multifile mf_personnel database, the command procedure builds a database called MF_PERSONNEL.RDB (plus related storage area files), regardless of the interface language used. When you build the multischema corporate_data database, the command procedure builds a database called CORPORATE_DATA.RDB. You can use only SQL to build the database. NOTE When you create the personnel or mf_personnel database, the log of the database definition statements used in creating the database is placed in a file called PERSONNEL.LOG in the same directory as the database. When you create the corporate_data database, the log of the database definition statements used in creating the database is placed in a file called CORPORATE_DATA.LOG in the same directory as the database. The personnel command procedure consists of several smaller command files, executable files, and data files. These files are located in the directory RDM$DEMO. You might want to use these files as models in creating your databases. For additional information about creating the sample databases, read the online file ABOUT_SAMPLE_DATABASES.TXT. This file is located in the Samples directory.
