Create JES3 initialization stream checker data

Because JES3 does not access the IODF directly, it has to be checked whether JES3 I/O and MVS I/O definitions are the same. It is essential that these definitions are consistent. Each time you run this task, the JES3 initialization stream checker data is stored in a data set, thus allowing JES3 to check the above mentioned definitions and to detect inconsistencies among them.

You can start the task from a work IODF as well as from a production IODF. However, it is recommended to use a production IODF to ensure that the same information is used for IPL.

1. On the Primary Task Selection panel, select Activate or process configuration data.
2. On the resulting panel select Create JES3 initialization stream data. HCD displays the Create JES3 INISH Stream Checker Data panel.

3. Specify the required values.

   The output data set will automatically be allocated (record length 80, record format fixed block). Depending on whether you specify the data set name as sequential or partitioned, the data set will be either sequential or partitioned. It is recommended to specify a partitioned data set (PDS), because this is required by the JES3 initialization stream checker.

   If the data set already exists, you will be asked to confirm replacing it with the new one.

You can also invoke this task in batch mode. See Build I/O configuration data for a description of the job control information that you need to specify when you build JES3 initialization stream checker data.
