ADAREORG on the server platform is very similar to the mainframe version. It enable the DBA to make complex changes to database files with the minimum of effort and risk. This avoids complex programming in Natural and testing requirements associated with this approach.
The simple command language enables the rapid implementation of changes as required from DEV, TEST and through to PROD with minimal downtime. In fact ADAREORG runs in a very similar fashion to the standard ADABAS utilities.
