Adding an Owner Record and Set to an IDMS Record

Adding an Owner Record and Set to an IDMS Record

Add one or more owner records and sets to a record in an IDMS data map.
To add an owner record and set to an IDMS record:
  1. Open the IDMS data map.
  2. On the
    Data Map
    tab in the
    Resource Explorer
    , right-click the record and click
    Properties
    .
    The
    Record Properties
    dialog box appears.
  3. On the
    Owner Record and Set Names
    tab, click the
    Add New
    toolbar button.
    The
    Owner Record and Set Properties
    dialog box appears.
  4. On the
    Owner Record and Set Details
    tab, define the owner record and set properties.
    The following table describes the information to enter:
    Option
    Description
    Owner Name
    Enter the name of the parent record. Enter SYSTEM to identify the set as a system-owned index.
    Set Name
    Enter a description of the relationship between the record and owner.
    Area Name
    Enter the name of the area in which the owner record and index structure are located. Enabled when you edit an existing owner record and set with an owner name of SYSTEM.
    Order
    Select the logical order for adding new member record occurrences to a set occurrence at run time:
    • None
    • First
    • Last
    • Next
    • Prior
    • Sorted
    If you select
    Sorted
    , the
    Sort Element Name
    tab appears on the
    Owner Record and Set Names
    dialog box. Click the
    Sort Element Name
    tab to set the sort order for elements.
    Default is none.
    Mode
    Select the set characteristic that determines how CA IDMS/DB pointers are maintained at run time:
    • None
    • Chain
    • Chain Linked to Prior Index
    • VSAM Index
    Default is none.
    Duplicates
    Select how CA IDMS/DB handles a record occurrence with a sort key that duplicates the sort key of an existing occurrence:
    • None
    • By DBKey
    • First
    • Last
    • Not Allowed
    Default is none.
    Set Options
    Select one of the following set options:
    • None
    • Mandatory Automatic
    • Mandatory Manual
    • Optional Automatic
    • Optional Manual
    Default is none.
    Natural Sequence
    Select this option to use the natural sort sequence, which sorts and evaluates the key fields using negative values before positive values.
    Clear this option to use the default sort sequence. By default, CA IDMS/DB sorts and evaluates the key fields using a standard collating sequence, which sorts data by its hexadecimal value.
    Default is cleared.
    Linked to Owner
    Select this option to link each member record of the specified type in the set to the owner record.
    You cannot change this option if the relationship is already being used by a defined table in the data map.
    Owner Key Position
    Enabled if the
    Linked to Owner
    option is selected.
    Enter the position within the record of the owner key. This value is the owner database key position or the index value, relative to 1, defined in a schema set statement. If you do not enter a position value, a value is automatically assigned.
    Default is 0.
    Owner Page Group
    Enter the IDMS page group of the owner record.
    Maximum value is 32767. Default is 0.
    Owner Radix
    Enter the IDMS radix for the owner record.
    Valid values are from 0 through 12. Default is 8.
  5. Click
    OK
    .
    The owner record and set appears in the
    Owner Record and Set Names
    list on the
    Owner Record and Set Details
    tab.
