Step 2—Prepare Total DDL Statements

After you select the Total database you want to convert, make sure you have all of the relevant Total DDL in a file. This file is part of the input to the generator.

If you are converting an entire database, you may already have the input file you need. If you are working with part of a database, however, you must prepare the input file appropriate to your conversion.

Comments in the Total DDL

If column 1 of a Total DDL input statement is blank, the generator considers the statement to be a comment and ignores it. This allows you to retain all of the original source DDL while selectively disabling some of the statements.

Limits on the Total DDL

At installation, the generator is set up to handle Total DDL input for up to 300 files, 5900 elements, 500 linkpaths, and 500 record codes. These limits are usually adequate for initial use of the transparency. If your DDL file exceeds these limits, see Increasing Generator Input Limits for information on increasing the limits.
