Introduction to Natural modernization
This page will guide you through the creation of a new Natural modernization project.
Creating a Blu Age modernization project will transform your legacy code into a language understandable by any developer. It will also enhance your team productivity by :
- Enabling the usage of an Integrated Development environment;
- Providing all the Blu Age modernization tools.
Natural Project Creation
To create a new BluAge Natural Modernization project, use the following steps :
- Right-click on the Explorer view;
- Select the menu entry New -> Other;
- Select Natural Reverse Project in the BLU AGE Reverse Modeling -> Natural Project folder;
- Enter a project name and click Next;
- The following screen will appear :
- First step is to find the location of your Natural legacy inputs. They can be imported either from a folder or from an archive file. Select the appropriate format as shown in (1) and then browse the location accordingly;
- You can then select Natural inputs character encoding, as shown in (2);
Set the value of DC attribute of Natural inputs with (3) combo box;
When you import configuration is correct, you can click on Finish.
The extraction process will start. It might take several minutes if the number of programs imported and/or their size is significant.
Natural Project Structure
Once the extraction process has finished, a new project is added to the package explorer view. Then, if not already done, you may want to build it.
- All inputs successfully extracted will produced a DSL file dslnat;
- Your files will be parsed against the BluAge Natural parser and parsing issues will be displayed in the Problems view of the IDE.
- The input (1) folder contains your Natural legacy inputs;
- The extractionReport.xml (2) file contains BluAge Natural extractor execution report
- Extraction summary
- Unresolved dependencies, it might be kind to resolved all of these before modernization starts
- Errors details
- The programDependencyCartography.csv (3) file summarizes project dependencies
- The output (4) contains all dslnat files from BluAge Natural extractor organized by source types
- DDMs : Database table descriptors
- Data Areas : Local, global and parameter data's description
- Helproutines : Messages or screen helping users
- Maps : Screen specifications
- Reports : Batch report specification
- DictionaryEntries : Extracted entries of Dictionary, these files can be used in Maps or Reports validation rules
- Programs : Main application source code files
- Copycodes : In legacy, Copycodes are injected in other files. Natural extraction make with some artificial Subprograms the others are injected like legacy
Knowledge Base Creation
In order to begin the modernization process, a BluAge Knowledge Base project must be present in the workspace. It will help you sharing many information on your modernization project such as annotations on your COBOL files, artifacts, scripts,...
