About this task
Before you can make changes to the data and pointers, you must provide information that identifies the initial segment or record that you want to display, and then specify the format in which you want the data displayed.
Procedure

-
In the Select IMS system panel, select the IMS system ID that you want to
work with by entering an S in the input field that corresponds to the IMS system ID. Then, press Enter.

In the Specify database panel, specify the database name or, for a partitioned database, the master DBD name
in the DBD name field. Then, press
Enter.

SMPORDP1IMS Database Repair Facility determines the database organization type and the access method that is associated with this database. This information determines which panel is displayed next. Typically, the Update libraries panel is displayed.
-
In the Update libraries panel, examine the libraries and, if necessary, update the libraries. Then, press
Enter.
The library names that are displayed on the Update libraries are the names that you specified on the Setup- Specify libraries panel. If you change the library names on the Update libraries panel, the new names become the default library names for this database until you modify them again.

These fields are mutually exclusive; if you use one field, you must leave the other field blank.
If the database is not contained in the dynamic allocation library, you can specify the name of a data set or a PDS member that contains a list of DD names and the data set names that are associated with the database in the List of DB data set names field. If you specify this field and press Enter, the TSO edit panel is displayed.
If the data set or PDS member was defined and the list is in the required format, IMS Database Repair Facility displays the contents. If the format is incorrect, IMS Database Repair Facility deletes the contents and formats the data set or member. If this data set or PDS member does not exist, IMS Database Repair Facility allocates or creates it and formats it.
In the TSO edit panel, enter or modify the data as needed. Then, press END (PF3).
