Database load function (online conversation)

The Data Base Load function consists of an online conversation and a batch job stream. The online screens prompt you for the information needed to submit the batch job to do the actual load.

The online conversation has a sequence of screens where you can do the following:

  1. Specify the job type of the load job (DLI or BMP).
  2. Specify the processing options to use (Load, Insert, Update, or Replace).
  3. Specify the dataset name of the load FROM file.
  4. Specify the PSB containing the PCB to be used for the load (static PSB only).
  5. Specify the DBD for the load TO database.
  6. When the primary DBD name in the FROM dataset is different from the TO DBD name, you can specify override values using the Load - DBD Name Override function.
  7. Specify the dataset names of the TO database (DLI region only).
  8. Specify the JCL information.
  9. Optionally edit the JCL generated by File-AID for IMS to perform the load.

Depending on the processing option used and whether secondary indexes and/or logical relationships are present, the batch job consists of three to nine steps. The main steps of the batch job perform the following actions:

  • Sorts the records in the load FROM dataset into the proper load sequence.
  • Reads the records from the sorted FROM file, strips off the File-AID for IMSprefix information, and inserts the segments into the TO database.
  • Writes a report that summarizes the results of the load.
