| Database Definitions (ttaad4110s000) |  |
| use.session.to define the details for the database definition, such as, the database type, database parameters. Enter the database code and a short description. If you want to use the database on a remote system, enter the system name. Specify the database type of the local, or the remote system. If you do not fill in the System Name field, the tabledef6.X file will only be created on the local system. If this field is filled in, the database is created both on the local system and on the remote system. Make sure that the BSE_REM variable is set. You can only do this if the remote system contains the data dictionary. On the local system, the tabledef6.X file refers to the remote system. The tabledef6.X file on the remote system shows the database type per table. If required, use variables in the Parameter field in order to define a database copy in another file system on your local system. If you change the data this does not mean that the databases are changed. Once an ORACLE database is created, it will remain an ORACLE database.

Fields | Description
Database | The identification code of the database in the Tools environment.
Description | Enter a short description of the database definition.
System Name | Enter the name of the system where the database is located. If the database is on the local system, and the system is not part of a remote database configuration, do not fill this field. Specify the database type of the local database in the Database Type field. If you use a remote database configuration, enter the name of the system where the database is located. Example Assume the following configuration: host 1 : the system where the database is located workst 1: work station 1 workst 2: work station 2 The application manager works on workstation 1 and starts the Database Definitions (ttaad4110s000) session. He must enter host 1, the system where the database is located, on the System Name field. This is the system where the database is located. The application manager specifies the database type of the tables in the Database Type field. When he starts the Create Runtime Database Definitions (Tabledef) (ttaad4113s000) session the application manager can specify to dump the tabledef file on the system where the database is located, workstation 1 and workstation 2. Note The application manager must have a remote user file in order to have access to the systems mentioned, to dump the table definition file, tabledef, on the system host1 and workst2.
Database Type | Enter the database type of the database definition code. The data of those tables assigned to a database definition code, is physically stored in its database (type). If the System Name name field is filled in, the database type of the remote system can be defined on this field. You must use this for converting data to the tabledef6.1 file on the remote system. Tools supports several database types.
Parameter | If required, enter a parameter. If you use parameters, you can define a database copy in another file system on your local system. If the file system crashes, you still have a backup copy which is located on another file system. The databases ORACLE and Informix use parameters, and environment variables in order to indicate tables. For example, an ORACLE database can have the following parameters: ORACLE_HOME=/usr/oracle7,ORACLE_SID=d1. Note It is recommended to create a database copy on a remote system.
Force to Read | If this check box is selected, the table is force read. If you use more than one database, or database redirections to another system, you can specify which database must be accessed for specific tables. Typically, the bshell accesses the database that has been specified as the first database in the table's database definition. There can be reasons, for example, performance, to read the table from another database (type). In that case, you can specify to force read table.
Copy(ies) Present | If this check box is selected, a database copy or alternative database exists.
