6.4.1 Creating a repository
The first thing to note when creating a repository is the great number of data sets that File
Export will generate. To avoid overcrowding the available disk space, limit the number of
Figure 6-8 gives an idea of the number of generated data sets per repository.
Figure 6-8 DSLIST of File Export repository
The repository contains records layouts: MVS, DB2, and IMS. Items of the same type can be
linked together in a global definition called a storage name.
You can start by loading data definitions and link them later in a storage. This process for
MVS data will be described in the following paragraphs.
For DB2 data, start by creating a storage name and then specifying the table definitions you
want to load from the DB2 catalog.
For IMS data, start by creating a storage name and then specifying the segment definitions
you want to load from the IMS library.
6.4.2 Load a data definition from a COBOL copybook
Start the File Export Repository management function, open the repository, display the list of
the existing data descriptions.
You can exclude from the display the default record types corresponding to data definitions
loaded from a DB2 DBRMDLIB or an IMS DBDLIB.
The process is the same for a PL/I include.
