The edit process is just that. DBD source is extracted from Panvalet and edited by the XBA010 program. The output indicates edit warnings and errors. Errors must be corrected. Warnings can normally be ignored, but may point to problems with DBD changes. The input file is the DBD source. An output file is created which is edited source. The file names are as follows:
| Edited DBD Source Files | |
|---|---|
| System | File DSN |
| ZSS | AUP08.ZSS.*.XDS000 |
| SIS | AUP01.SIS.*.XDS001 |
| FRS | AUP02.FRS.*.XDS002 |
| HRS | AUP03.HRS.*.XDS003 |
| LMS | AUP09.LMR.*.XDS005 |
The update process starts by executing the XBA020 program. This program does the actual updating of DBD files. If the DBD edit was clean, there should be no problems here. However, the output of this step must be examined to assure that there are no problems. One of the outputs reports on the number of T1 records. This is a measure of online storage needed to store data translation tables. This number must be less than the number specified in the ZADTvT assembly program (where v is the ZSS system. This is specified near the bottom of the program. If the DBD indicates a larger number than in the ZADTvT module, increase the number in the module, reassemble it and newcopy it in the appropriate CICS region.
The next part of the process is the ZBA070 program. This examines each of the application system's screens and makes sure the data elements on the screens exist in the DBD. If not, the process will terminate with a non-zero return code. Correct the problem as appropriate and rerun the DBD update. One of the potential errors concerns DO segments. These can normally be ignored, and are quite prevalent in the Purchasing section of FRS.
The next part of the process is to rebuild the online documentation with refreshed data translation values and data element information. This is done with the ZBA075 program and several IDCAMS processes. Examine the output to make sure no problems have occurred.
The next part of the process is system-specific. A DBD update can add new elements, delete old elements and change existing elements. Many files have a/many format record(s). This record is used to store default alpha/numeric values used when creating new records. These must be updated. Each ZSS application system has its own default record generator. This/these program(s) normally run as the last step of the DBD process.
