MIBJ - Migration perimeter
All the VA Pacbase Programs and Screens are not in production. A migration help is proposed for these entities. It determines if the migration must be effective, standard or partial. To prevent manual modifications in the repository (deletion of the "Type of COBOL to generate" for example) or in the INPUTMIAn files (deletion of entities for example), the MIBJ procedure automates these actions.
This procedure enables you to constitute filters from the MIAMNREP and MIAMNMIG files (produced by the MIAM procedure), and from the USERNREP (PAC7NT) and USERNMIG (PAC7NM) user files.
You can select a list of entities not to be migrated.
You can assign a migration help MODE to the entities.
Filter of the model:
Pos. | Len. | Meaning |
---|---|---|
1 | 3 | Library code |
4 | 3 | PAF type |
7 | 30 | Entity code |
Filter of the entities to be generated:
A MODE option is created for the migration help. It can take the following values:
- N: No migration of the source code (the design is migrated),
- S: Standard migration.
Pos. | Len. | Meaning |
---|---|---|
1 | 3 | Library code |
4 | 3 | PAF type |
7 | 30 | Entity code |
49 | 1 | Migration help mode |
The MIAMNMIG file that is produced by the MIAM procedure contains the Screens or Programs whose source code is not to be migrated (Screens with a Definition only or with Descriptions only). It is concatenated with the USERNMIG file and transformed into an indexed file.
When the command files of the MIAn procedures are created, the migration help MODE option is deduced from the indexed file. If the entity is not to be migrated, it is not included in the INPUTMIAn files.
Sample MIA2 command line:
Z90GCO SCREENC9 MODE=S
