Executing a DELTA List

To Execute a DELTA List

1. Go to the DELTA List Edit/Execute Entry panel.From the DELTA PLUS Main Menu, type 1 in the selection field and press Enter. The DELTA List Edit/Execute Entry panel is displayed.

2. Decide if you want to execute a specific existing DELTA List or choose an existing DELTA List for executing. Perform the appropriate action.

   Activity	Action
   execute a specific existing DELTA List	Type 2 in the selection field and the name of an existing DELTA List in the DELTA List field.
   choose an existing DELTA List for executing	Type 2 in the selection field and leave the DELTA List field blank or type a masking pattern in the DELTA List field.

3. Type the data set name of the library in which the existing DELTA List resides in the DELTA List library field.

4. View Profile —Type the name of the View Profile in the View Profile field; otherwise, accept the default View Profile.

   Note

   When UPF security is in effect, this field will be labeled IMSID or Group. Enter the IMSID or Group for which you intend to execute the DELTA List. The view profile used will be of the form DLAKWTnn for DELTA PLUS VIRTUAL TERMINAL or DDCKWTnn for DELTA PLUS for DBCTL, where nn is from the applicable UPF record.

   This field may not display on the panel if no View Profile data set is specified in the Global Options.

5. Press Enter.

   Previous Action	Result
   You typed 2 in the selection field and the name of an existing DELTA List in the DELTA List field.	The DELTA List Execution panel is displayed.
   You typed 2 in the selection field and left the DELTA List field blank or typed a masking pattern in the DELTA List field.	The member selection list is displayed, allowing you to select a DELTA List.

6. If you are on a member selection list panel, select a DELTA List to execute by typing S next to one of the DELTA PLUS PDS member names listed on the panel and pressing Enter.The DELTA List Execution panel is displayed.
7. Type 2 in the Execution type selection field.
8. Type the name of the target IMSID(s) or Group(s) against which you want to execute this DELTA List in the Target IMSIDs or Groups entry fields.

9. Ty pe the name of the Variable Definition Set in the Override Variable Definition Set field that contains the variable definitions you want for this execution of the DELTA List.The Variable Definition Set you specify will be used to resolve symbolic variables for this execution of DELTA List instead of the Variable Definition Set specified in the DELTA List Options for this DELTA List.

   Leave this field blank if you want to use the Variable Definition Set specified in the DELTA List.

   Note

   The Override Variable Definition Set will be used to resolve symbolic variables in any nested DELTA Lists.

10. Type a / in the selection field next to one or more of the following options to select option(s):

    Option	Description
    Reset results list	Resets the results list. A results list is the information returned at the completion of a DELTA List detailing the outcome of DELTA List Check or Execute. Resetting the results list indicates to DELTA PLUS to discard the output from any previous DELTA List Check or Execute.
    Coordinate elements across IMS systems within each specified group	Ensures that changes to resources contained in the DELTA LIST are coordinated across all IMS control regions in the Group. If there is an error in any element in the DELTA List on any of the IMS control regions, then no changes will be occur on any IMS control region to ensure that the systems remain in synchronization. This option is valid only when the target is a Group.
    Execute Marked elements only	Indicates that only those elements in the DELTA List that have been marked for execution will be processed. Any element that is not marked will be ignored. If this option is not selected, then all elements in the DELTA List are processed.

11. Type the appropriate option number in the Execution mode selection field to indicate whether you want to execute the DELTA List in optimized mode or one element at a time.

    Note

    If you choose optimized mode, the entire DELTA List is sent to the target IMS control region(s) and all the elements are processed together. This mode processes a DELTA List in a more efficient manner. If the DELTA List contains a mixture of dependent and independent DELTA Lists, then processing may occur in multiple passes as each dependent or independent collection of elements is processed as a single unit of work.

    If you choose to process the DELTA List one element at a time, each element in the DELTA List is sent to the target IMS control region(s) individually and processed before the next element in sequence is processed.

12. Optional. If you select the One element at a time option in the Execution mode field, you can type a / in the selection field under it to have the processing of the DELTA List pause when any errors are encountered.You will then be given the option of continuing the DELTA List processing with the next element or canceling the DELTA List processing.
13. Press Enter.
