Abstract

Methods, systems, and computer program products for file version control management are provided. Methods include receiving a loadset of at least one data file and activating the loadset. For each data file in the loadset, the data file is written to a target system and identified by a base name and a generation number. A symbolic link with an activation number is created in a version control file index (VCFX) to the data file written to the target system. An application view to the symbolic link is provided as the base name of the data file, and the application view to the symbolic link is limited based on an activation number of the application corresponding to the activation number of the symbolic link.

Claims

1. A method for file version control management, the method comprising:

receiving a loadset of at least one data file; and

activating the loadset, comprising;

for each data file in the loadset;

writing the data file to a target system and identifying the data file by a base name and a generation number;

creating a symbolic link with an activation number in a version control file index (VCFX) to the data file written to the target system;

providing an application view to the symbolic link as the base name of the data file; and

limiting the application view to the symbolic link based on an activation number of the application corresponding to the activation number of the symbolic link.

2. The method of claim 1, further comprising:

accepting the loadset, comprising;

renaming each of the data files written to the target system to the base name of the data file; and

removing the symbolic links to each of the data files.

3. The method of claim 1, further comprising:

deactivating the loadset, comprising;

removing the symbolic links to each of the data files written to the target system; and

removing each of the data files written to the target system.

4. The method of claim 1, wherein the loadset further comprises at least one program.

5. The method of claim 1, wherein the data file is included in the loadset.

6. The method of claim 1, wherein the data file is affiliated in the loadset.

7. The method of claim 1, wherein the data file is a program base unique file.

8. The method of claim 7, further comprising:

linking the program base unique file to a program base through a virtual directory.

9. A system for file version control management, the system comprising:

a target file system;

a version control file index (VCFX); and

an online loader application, the online loader application performing;

receiving a loadset of at least one data file; and

activating the loadset, comprising;

for each data file in the loadset;

writing the data file to the target file system and identifying the data file by a base name and a generation number;

creating a symbolic link with an activation number in the VCFX to the data file written to the target file system;

providing an application view to the symbolic link as the base name of the data file; and

limiting the application view to the symbolic link based on an activation number of the application corresponding to the activation number of the symbolic link.

10. The system of claim 9, wherein the online loader application further performs:

accepting the loadset, comprising;

renaming each of the data files written to the target file system to the base name of the data file; and

removing the symbolic links to each of the data files.

11. The system of claim 9, wherein the online loader application further performs:

deactivating the loadset, comprising;

removing the symbolic links to each of the data files written to the target file system; and

removing each of the data files written to the target file system.

12. The system of claim 9 wherein the loadset further comprises at least one program.

13. The system of claim 9, wherein the data file is included in the loadset.

14. The system of claim 9, wherein the data file is affiliated in the loadset.

15. The system of claim 9, wherein the data file is a program base unique file.

16. The system of claim 9, wherein the online loader application further performs:

linking the program base unique file to a program base through a virtual directory.

17. A computer program product for file version control management, the computer program product comprising:

a storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for facilitating a method comprising;

receiving a loadset of at least one data file; and

activating the loadset, comprising;

for each data file in the loadset;

writing the data file to a target system and identifying the data file by a base name and a generation number;

creating a symbolic link with an activation number in a version control file index (VCFX) to the data file written to the target system;

providing an application view to the symbolic link as the base name of the data file; and

limiting the application view to the symbolic link based on an activation number of the application corresponding to the activation number of the symbolic link.

18. The computer program product of claim 17, wherein the instruction further facilitate:

accepting the loadset, comprising;

renaming each of the data files written to the target system to the base name of the data file; and

removing the symbolic links to each of the data files.

19. The computer program product of claim 17, wherein the instructions further facilitate:

deactivating the loadset, comprising;

removing the symbolic links to each of the data files written to the target system; and

removing each of the data files written to the target system.

20. The computer program product of claim 17, wherein the loadset further comprises at least one program.
