ZSS DBD Training/The DBD Update Process

The DBD Jobs

The Basic DBD Jobs

AU3115

AU3115 is the basic DBD source edit. This edits the transactions in the DBD source and indicates if any problems were found. Some messages are warnings and some are errors. There is no clean way of determining which warnings can be ignored. Experience with the process is the best guide.

The edit job first extracts the DBD source(s) from Panvalet. The order of extraction when multiple sources exist is quite important. Make sure the order is as specified in the default SCT-supplied JCL.

Next, the XBA010 program is invoked. It does the actual edit. If the edit is successful, an edited source file (the XDSnnn file) is created. It is used for the DBD update process and in DBD reporting.

The edit process executes the XBA010 program.

Sample Output

AU3119

AU3119 exists only in the production environment. It is used to close necessary files to Production CICS for the DBD update process.

The job first attempts to invoke the ZFOC transaction to close files. If this is unsuccessful, the files are closed by invoking the CAFC process.

AU3120

This is the heart of the DBD process. It takes the edited DBD source from AU3115 and updates the DBD files. It also validates the screens in the system being updated and refreshes its online documentation with the most recent data translation values.

The update process executes the XBA020, ZBA070 and ZBA075 programs.

AU3121

AU3121 exists only in the production environment. It is used to reopen files to Production CICS after the DBD update process completes.

The job first attempts to reopen files by invoking ZFOC. If this is unsuccessful, CAFC is invoked to open the files. By using this method, the online tables needed by ZSS application systems are reloaded, preventing online problems.

Other DBD Jobs

There are two other jobs that sometimes accompany a DBD cycle. If there are new screens or procedures that need to go into production, they must first be placed in the screen and/or procedure transfer bins. This is done by using the SPX ZST option. This option transfers items one at a time. A VSAM REPRO can be used if a large number of screens or procedures need to be moved. This must be done using the REPLACE option. The transfer files are:

AU3101

This job will migrate screens from the transfer file into the production screen file. This should only be used if there are screens which need to be migrated into production. This job is normally run before the normal DBD cycle. If this job is scheduled to run independently of the DBD process, it must be followed by AU3118Zv.

AU3102

This job will migrate procedures from the transfer file into the production procedure file. This should only be used if there are procedures which need to be migrated into production. This job is normally run before the normal DBD cycle. If this job is scheduled to run independently, no further action is necessary.
