Specifying the Unload Data Sets

Before unloading data from source or target tables, specify which data sets will be used as destinations for unloading the tables. Otherwise, Data Compare uses data sets with names generated in the following manner.

Before unloading data from source or target tables, specify which data sets will be used as destinations for unloading the tables. Otherwise, Data Compare uses data sets with names generated in the following manner.
How Unload Data Set Names Are Generated
The unload data set names are generated by Data Compare if not specified. Data Compare uses Model Services for generation. The format depends on the model used to generate the data sets.
To choose user-specified names for the unload data sets, enter the high-level and secondary qualifiers, without quotes. Data Compare adds .DATA to the end of the data set name. For example, USER5.TABLE1 would generate the data set name USER5.TABLE1.DATA.
If the data set names (generated by either method) are the same, Data Compare makes them unique by adding a time stamp. Data is not overwritten.
View or Update Unload Data Set Names
To view or update the data set names currently attached to the data compare strategy, issue the
E
(Edit) line command next to the table pair on the Data Compare Explode Services panel.
After entering
E
and pressing Enter, the Data Compare Dataset Specification screen appears.
The strategy name, creator, description, and share option are displayed. None of these fields can be changed. The creators and table names of both the source and target tables for the current data compare strategy are also displayed. These fields cannot be changed on this screen.
The following fields can be filled in or changed on the screen.
  • SOURCE DATASET
    Enter the data set that holds the unloaded data for the source table.
  • TARGET DATASET
    Enter the data set that holds the unloaded data for the target table.
The source data set name and target data set name are the only fields that can be changed. After changing these data set names, enter
SAVE
on the command line to link the revised names to the Data Compare strategy. Then press F3 (End) to return to the Data Compare Explode Services panel; or press F3 (End) to return to the Data Compare Explode Services panel without making changes to the data set names.
