This document covers the following topics:
When PAC is initialized, a set of Predict generation defaults called "DEFAULTS" is automatically defined for use with migrations of Predict data into PAC.
Additionally, the PAC administrator may copy and store different sets of Predict generation defaults from Predict and may assign to each a specific name for use with migrations of Predict data into PAC.
The defaults to be used with a Predict migration event can be specified during authorization by entering the appropriate name of the defaults set previously saved.
If no defaults set is specified for a migration of Predict data into PAC, the default set DEFAULTS is used.
Note:
Note: If the DEFAULTS set is not found or if the specified set is
not found, error 7012 is returned, indicating the defaults set that could not
be located; the migration terminates at the generation step.
Generation defaults for Adabas files have up to ten (10) databases to which files may be linked. On the Copy View Defaults screen, the Adabas Subsystem Specification DB-ID parameter determines whether a linked database is required. (This means that the generated DDM will not be assigned a DBnr.)
If the DB-ID=N is set in the stored generation defaults of Predict, a DDM with DBnr=0 is generated, even if the file is linked to several databases.
If DB-ID=Y is set in the stored generation defaults, Adabas files can be linked to databases. Note the following:
Where no database is linked, the generation aborts and error 2047 is returned.
Where one database is linked, PAC generates the view/DDM, using this database. The resulting DDM will have this database Dbnr.
Where several databases are linked, PAC determines the database as follows:
If the file is linked to one or more databases in the object list of the event, PAC takes the first database in alphabetical order.
If the file is linked to one or more databases in the generation defaults, PAC takes the database from there. A database can be specified for each event for which the generation defaults set is used. PAC checks sequentially to determine whether the userview is linked to a database. The first database found with a link to the userview is selected for the generation.
If the user exit PACEX037 is active, PAC invokes the exit before the generation command is built in order to determine the linked database to be used for the DDM generation. If no linked database is found or DBID=N is set, a blank is passed to the exit. The user exit may then verify, override, or reset the linked database name.
From the Predict Generation Defaults menu, you can copy, display, purge, or select Predict userview generation defaults; and modify the list of linked databases.
From the General Defaults menu, enter Code G (Predict Generation Defaults).
The Predict Generation Defaults menu appears:

In addition to the Code field, the following input fields are available for processing generation defaults:
| Input Field | Description | |
|---|---|---|
|
|
||
| Defaults Name | Name of the set of generation defaults. The name can be 1 to 8 characters long and have any combination of characters. | |
| Predict DBnr/Fnr | Database number (DBnr) and file number (Fnr) of the Predict (FDIC) file from which the new defaults are to be copied. | |
| Replace | Used with subfunction code C (Copy Generation Defaults from
Predict). If a set of generation defaults already exists with the specified
name: N (Default): The existing set is not replaced; Y: the existing set is replaced. |
|
You can copy the Predict generation defaults in your FDIC file to the PCF system file.
The generation defaults, as they are currently defined in the referenced FDIC, file will be copied.
Note:
The values for these are not modifiable in PAC. To change the
options, you must change the values in Predict, then copy the defaults into
PAC.
The following are forced defaults for the DDM generation defaults.
| Parameter | Default | |

To copy Predict generation defaults:
Enter Code C (Copy Generation Defaults) and a name for the Predict userview generation defaults to be copied.
The Copy View Defaults screen appears, displaying the Predict userview generation defaults to be copied:

Note:
Except for the Linked Databases List, the values for these
defaults are not modifiable in PAC. To change the options, you must change the
values in Predict, then copy the defaults into PAC.
To modify the linked databases, type Y over the default in the Linked Databases List field.
For more information, refer to Modify Linked Databases.
To copy the generation defaults, press ENTER. Or, to terminate the function without copying the defaults, press PF3 (Exit) or PF12 (Canc).
When you press ENTER, the Verification Defaults window appears, verifying that rules as well as views will be copied.
To complete the copying of the generation defaults, press ENTER. Or to terminate the function without copying the defaults, press PF3 (Exit) or PF12 (Canc).
The message "Generation Defaults have been copied." appears on the Predict Generation Defaults menu after you have successfully copied the Predict generation defaults to your PCF system file.
To modify the list of databases linked to the Predict
userview generation defaults
access the Modify Linked Databases List screen in one of the following ways:
| From this Screen | User Action | |

modify or add the database names of up to 10 databases;
The database names can be entered, using uppercase or lowercase text; however, the first character must be capitalized.
modify the entry in the Title field, which is used to specify an extended name or description for the generation defaults set;
press ENTER to confirm your modifications.
You are returned to the Predict Generation Defaults menu.

The Display View Defaults screen lists the generation defaults for the specified Predict userview. This screen is similar to the Copy View Defaults screen; however, the Display View Defaults screen may not be modified.
To display a list of databases linked to the generation defaults, type Y over the N default in the Linked Databases List field.
The Display Linked Databases List screen appears. The linked databases list may not be modified. For an example of a similar screen, refer to Modify Linked Databases.
The purge function is used to purge the defaults for both rules and userviews.
To purge a Predict generation default set, access the Purge Confirmation window in one of the following ways:
From the Predict Generation Defaults menu, enter Code P (Purge Generation Default) and the name of the generation default set to be purged in the Defaults Name field.
From the Predict Generation Defaults Selection List, mark the desired generation default set with P in the "C" column.
From the Purge Confirmation window, do one of the following:
To purge the Predict generation defaults, enter CONFIRM or press PF5.
To terminate the function without purging the defaults, enter a period (.) or press PF3 (Exit) or PF12 (Canc).
The message "Predict ... Generation Defaults purged" appears after you have successfully purged the Predict generation defaults.
To display a selection list of all Predict generation default sets, enter Code S (Select Generation Defaults). Use range notation if you want to limit the list of generation defaults.
The Predict Generation Defaults Selection List screen appears displaying a list of Predict generation default sets which have been copied into PAC as shown in the following example:

To display a specific set of Predict generation defaults on the Display View Defaults screen, mark the defaults set with an X in the C column, or enter the number (from the Nr column) in the Mark Selection... field.
You may modify a linked databases list (M), display generation defaults (D), or purge generation defaults (P) directly from this screen by marking the name of the generation defaults set with the appropriate code in the C column. Refer to the relevant sections for examples of the resulting screens.
