Accessing in BMP mode using a Dynamic PSB

Before you can access a database in BMP mode using a Dynamic PSB, your FM/IMS system must have been set up to allow this type of access. This is a task that is performed by your FM/IMS administrator, during the installation and customization of the FM/IMS environment.

  1. Select either option 1 Browse or option 2 Edit from the Primary Option Menu. The Browse Entry Panel or Edit Entry Panel is displayed.
  2. In the Subsystem name field, enter the ID of the IMS subsystem that the database you want to access is defined in, or if you want to select the required subsystem from a list, enter a subsystem name pattern or leave the field blank.
  3. In the Database name field, enter the name of the database that you want to access, or if you want to select a database from a list of DBDs, enter a database name pattern or leave the field blank.
  4. If the subsystem that you specified uses AGNs, enter in the AGN name field, an AGN name that will provide you with the access the function requires and that you have authority to use or, if AGNs for the subsystem are listed in the installation options module and you want to select an AGN from the list, enter an AGN name pattern or leave the field blank. If the subsystem that you specified does not use AGNs, no AGN name should be entered.
  5. If you want the function to use an existing view, enter in the View data set name field, the name of the data set that contains the view you want the function to use or, if you want to select the data set from a data set list, enter a data set name pattern. If the selected data set is partitioned, enter in the View Member field the view member name, or if you want to select the required view member from a list, enter a view member name pattern or leave the field blank. If the selected data set is not partitioned, leave the View member field blank.
  6. In the PSB type field, enter 1 to select a dynamic PSB.
  7. In the Region type field, enter 2 to select a BMP region.
  8. In the View usage field:
    • Enter 1 if you want the function to use a new view. The function creates a temporary view from the template for the database.
    • Enter 2 if you want the function to use the existing view you specified in the View data set name and Member fields.
    • Enter 3 if you do not want the function to use a view.
  9. If the database you selected has secondary indexes and you want to access the database by means of a secondary index, enter "/" in the Secondary index field.
  10. Press Enter to process the data you entered. According to what you entered on the panel, one or more of these panels may be displayed in the order they are listed:
    • Subsystem Selection panel
      • Displayed when you enter no subsystem name or a subsystem name pattern.
      • Displays a list of IMS subsystems defined by the FM/IMS administrator at installation time.
    • Database Selection panel
      • Displayed when you enter no database name or a database name pattern.
      • Displays a list of the DBDs in the DBD libraries for the specified subsystem.
      If the DBD libraries for the subsystem are not fixed, you specify the DBD libraries for the subsystem on the PSB and DBD Data Sets panel (option 0.6.7). If the DBD libraries for the subsystem are fixed, the FM/IMS administrator specifies the DBD libraries for the subsystem at installation time.
    • AGN Selection panel
      • Displayed when the specified subsystem uses AGNs and has some of them listed in the FM/IMS installation options module and you enter no AGN name or an AGN name pattern.
      • Displays the AGNs for the subsystem that are listed in the FM/IMS installation options module.
    • View Data Set Selection panel
      • Displayed when you enter a View data set name pattern and select "Existing" for View usage.
      • Displays a list of the data sets whose names match the specified View data set name pattern.
    • View Member Selection panel
      • Displayed when the specified View data set is partitioned, you enter no View member name or a View member name pattern and you select "Existing" for View usage.
      • Displays a list of the members in the View data set.
    • Secondary Index Selection panel
      • Displayed when you select the Secondary index option and the database that you selected has more than one secondary index.
      • Displays all the secondary indexes for the selected database.
    On each selection panel that is displayed, enter S in the Cmd field adjacent to the item you want to select and press Enter.
  11. Once you have completed these steps, the Database Positioning panel is displayed. You complete the access process by setting up the way you display the segment data. This process is described in Determining how to display your data.
