Locked Data Maintenance

Data is locked by PAC when it is being processed. Users can unlock data which they themselves have locked.

Note:
Only a PAC administrator can unlock data which has been locked by other users.

If a migration event is not successfully completed, the data it locked remains locked. An uncompleted event can be resubmitted. In this case, an attempt is made to resume its processing from the beginning of the first uncompleted step. The PAC administrator can reset an uncompleted event. In this case, the data locked by the migration event remains locked. If, however, the event is resubmitted, it is restarted from the beginning rather than from the last step reached. The PAC administrator can also release an uncompleted event. If the event has not reached step 6, it is backed out. If it has reached step 6, its completion is forced.

On the Administrator Functions menu, enter Code L (Locked Data Maintenance). Or enter the command UNLOCK on the command line of any PAC menu.

  • the version number of each object migrated by the locked migration event;

  • The state of each locked object. The possible status values are:

    Check in of an object being migrated from maintenance;
    Check out of an object being migrated to maintenance;
    Roll in of a compile time subordinate which is being entered into the PCF system file to be used at the compilation incident to migration;
    Roll out of a versioned object being replaced in the PCF system file by another of the same name to be used at the compilation incident to a migration;
    Locked of the migration event that has caused the locking; of the application locked; of an object being migrated from or to a type other than maintenance; of an object being aligned or retired.

Release Locked Data

Warning:
The releasing of data locked by a migration event, which has not reached step 6, is accompanied by the undoing of the migration effects. The releasing of data locked by a migration event, which has reached step 6, forces the event's completion - for example, newly migrated objects stay in CONTROL.

Start of instruction set To release locked data use the following procedure.

  1. To access a Release Locked Data screen, do one of the following:

    • On the Administrator Functions menu, enter Code R (Release Locked Data) and optionally enter a user ID in the User field to limit the list.

    • On the Display Locked Data screen, mark the locked entity with R in the "C" column.

    This screen provides the same information as the Display Locked Data screen - that is, it lists the name and type of a locked entity; the cause of the locking (modification, deletion or migration); the user ID of the user who locked the entity. Each entry is assigned a number on the screen ("Nr" column); and an input field is provided for selecting an entry ("C" column).

    Press PF11 to display the ID of the terminal from which the data were locked and the date and time at which the data were locked. Press PF10 to again display the cause of the locking and the user ID.

  2. Select the data you want to release by

    • either entering the number of the entry (from the "Nr" column) in the Mark Selection field;

    • or by entering Rs in the "C" column next to the entries;

    • or by marking the entry with the cursor.

    If you select data that is not locked by a migration event, the Release/Reset/Undo Confirmation window appears:

    It is similar to the Display Locked Data window because it provides the following information: the entity locked; whether it was locked by a batch job or from an identified terminal; the time at which it was locked; and the cause of the locking.

    If you select data which is locked by a migration event, the Release/Reset Confirmation window appears:

    It is similar to the Display Locked Data window because it provides the following information: the event that caused the locking; the origin and the destination statuses; and the number and description of the step reached by the event. You can release the locked data or reset / undo the migration event. The resetting is described in section Reset a Migration Event.

  3. On either the Release or Release/Reset Confirmation window

    • To release the locked data, enter RELEASE.

    • To exit the window and display the Release Locked Data screen again without unlocking the data, enter a period (.), or press PF3 or PF12.

    When you enter RELEASE, the Release Locked Data screen appears. The layout of the screen depends on the type of data being released.

    If data locked by a migration event is being released, the screens look like this:

    The screens are similar to the Display Locked Migration Event Data screen with the exception that, in the rightmost column, actions performed on the entities are listed rather than the status of the entities.

    • To scroll through the complete list of entities, press ENTER.

    • To interrupt the unlocking and to return to the Release Locked Data screen enter a period (.) or press PF3.

    Release Locked Data screen displays one of the following messages:

    • "... data released", if the selected data was released;

    • "... was not released", if some of the selected data was not released.

Reset a Migration Event

When a migration event is reset, the following occurs:

  • The step number of the event is reset to 1.

  • The audit report is deleted.

If the event is then resubmitted, the data locked by it is released and the event is immediately restarted from the beginning. Since the application remains locked between the resetting and the resubmission, the state of the application's compartment will be the same at both submissions. It can, however, occur that the states of the compartments of the steplib applications or application Predict are different at the two submissions. Also, the states of any migration may change from the first submission to the second.

Start of instruction set To reset a migration event, use the following procedure:

  1. Enter Code R (Release Locked Data) on the Locked Data Maintenance menu.

    A Release Locked Data screen appears.

  2. On the Release Locked Data screen, select the migration event to be reset either by entering an R or placing the cursor in the "C" column, or by entering the number (from the "Nr" column) in the Mark Selection field.

    A Release/Reset Confirmation window for the migration event appears:

You have the option of releasing the locked data, resetting the migration event or undoing the migration event.

Enter UNDO.
