# INPL Utility

The INPL utility (Initial Natural Program Load) is used to load or scan Natural objects and shared resources from files.

The INPL Utility documentation covers the following topics:

- Introducing the INPL Utility

- Load Libraries Only

- Load DDMs Only

- Load Error Messages Only

- Load All Objects

- Scan INPL File

- Natural Security Recover

- User Exit Routines

#### Notation vrs or vr:

When used in this document, the notation `vrs` or `vr` represents the relevant product version (see also Version in the Glossary).

## Introducing the INPL Utility

The INPL utility processes Natural objects and shared resources .

The following diagram is a basic illustration of the INPL functionality:

The Natural objects and shared resources are delivered as installation or update files which are assigned to Work File 1. The INPL utility loads the Natural objects and shared resources from Work File 1 into Natural system files.

The Natural objects and shared resources include cataloged objects and source objects that are contained in libraries in the Natural system files FNAT and FUSER.

In addition to loading Natural objects and shared resources, the INPL utility provides a scan function to check the contents of the file assigned to Work File 1 and a Natural Security Recover function which forces initialization of the Natural Security environment.

When loading cataloged objects into Natural system files, the INPL utility deletes any buffer pool entries of cataloged objects with identical names if contained in the same buffer pool used by the INPL utility.

If an error occurs during INPL execution, the INPL will be interrupted and terminate abnormally with Condition Code 40.

This section covers the following topics:

- INPL Restrictions

- Special Case

- Invoking INPL

- INPL Options Available

- INPL Report

### INPL Restrictions

You can process only files which are marked as "SAG system INPL file".

### Special Case

When an INPL is to be performed in a Natural Security environment, the INPL command can be specified using the dynamic Natural profile parameter `STACK`.

### Invoking INPL

To invoke the INPL utility

1. Enter the following Natural system command:

       INPL

   An INPL menu similar to the example below is displayed:

2. From the INPL menu, you can choose one of the following functions by entering the corresponding function code in the Code field:

   - Load Libraries Only

   - Load DDMs Only

   - Load Error Messages Only

   - Load All Objects

   - Scan INPL File

   - Natural Security Recover

   For detailed information on these functions, refer to the corresponding sections. Modify or complete the remaining input fields as described in Options Available.

3. Choose ENTER to confirm your entries.

### INPL Options Available

The following section describes the input fields on the INPL menu where you can specify the file to be used for the INPL and one or more parameters as object selection criteria for the INPL function specified in the Code field. The use of a parameter depends on the respective function as indicated in the relevant documentation sections.

Field | Description
--- | ---
Replace | Specifies whether the Natural objects and shared resources to be processed are to replace any that already exist on the system files. Possible settings are:
`Y` | All existing Natural objects and shared resources are replaced. This is the default setting.
`N` | Existing Natural objects and shared resources are not replaced.
`O` | Resets the owner information of specified objects. Only applies to the function Natural Security Recover.
See also Check Date to replace only Natural objects and shared resources that are older than the Natural objects and shared resources to be processed. If you use the function Natural Security Recover, you can enter Option `O` in this field to reset the owner information of specified objects.
DDM Name | The name of a DDM or a range of names. If you enter a value that ends with an asterisk (*), each DDM with a name that starts with the specified value is processed. If only an asterisk (*) is entered or if this field is empty, all DDMs are processed.
Library | The name of a library or a range of names. If you enter a value that ends with an asterisk (*), each library with a name that starts with the specified value is processed. The library name is mandatory if Object Name is specified.
Object Name | The name of a Natural object (except DDMs) or a range of names. If the value ends with an asterisk (*), each object with a name that starts with the specified value is processed.
Check Date | Specifies whether existing Natural objects and shared resources are to be replaced depending on their time stamp. This parameter has no effect if Replace is set to `N`. Possible settings are:
`Y` | Only objects which are older than the Natural objects or shared resources of the same name are replaced. An object is older if it was saved or cataloged before the object to be loaded.
`N` | All objects are replaced. This is the default setting.
Load Except | Specifies whether to exclude Natural objects and shared resources from processing. This parameter does not apply to error messages. Possible settings are:
`Y` | All Natural objects and shared resources are processed except for the objects specified in the fields DDM Name, Library and/or Object Name.
`N` | No exceptions; all Natural objects and shared resources are processed. This is the default setting.
Examples of load exceptions: All libraries except the library ABC are loaded: Code = `L` Library = `ABC` All DDMs with a prefix other than XY are loaded: Code = `D` DDM Name = `XY*` All objects contained in libraries with a prefix other than AB and all DDMs with a prefix other than CD are loaded: Code = `B` Library = `AB*` DDM Name = `CD*`
Date | Restricts processing to Natural objects and shared resources which were saved or cataloged on or after the date entered in this field. The date must be entered in the format YYYY-MM-DD (YYYY = year, MM = month, DD = day).
Number | Limits processing of Natural objects and shared resources to a specified number. All objects are counted which are loaded or scanned according to the selection criteria specified in the INPL menu. If the number of Natural objects processed has reached the value entered in the Number field, processing is terminated with a corresponding message.
File Type (batch or direct commands only) | INPL automatically recognizes the type of the load file such as binary or portable. However, due to compatibility reasons, the `File type` parameter must still be specified when executing INPL in batch or direct command mode, but it will not be evaluated.
Load File | The name of the file to be loaded. Work File 1 is used. The name can be an environment variable pointing to the Load file. The name can be a text file containing a list of Load files. Work Files 1 and 2 are used.
Report File | The name of the file into which the INPL report (see below) is to be written. Work File 4 is used.

The following options are provided:

- Reset Environment

- Remove Owners

### Reset Environment

| Warning: Execution of this function will reset the user profile DBA and the library profile SYSSEC as well as the link between these two objects as they were after the initial installation; all other links to the library SYSSEC will be canceled. Other Natural Security profiles and links will not be modified. Contact support for further information.

To reset the environment

- In the INPL menu, enter function code `R`.

### Remove Owners

To remove owners

- In the INPL menu, enter function code `R` and enter an `O` in the Replace field to reset the owner information of specified objects.

## User Exit Routines

An INPL user exit routine is supplied as source object INPLSXnn in the Natural system library SYSLIB where nn denotes the ID of the user exit routine.

To activate a user exit routine

1. Copy the source code from SYSLIB into a user library.

2. Catalog it under the name `INPLUXnn.`

3. Copy it back into the Natural system library SYSLIB.

   Note
   The source object that you might have modified, and the cataloged object of the user exit routine are renamed to avoid them to be overwritten by an update installation.

The following user exit routines are available:

Name | Function
--- | ---
`INPLUX01` | Prevent error message texts to be replaced.

### INPLUX01

You can use this user exit to define ranges for error messages (user defined or Natural system error messages) that cannot be replaced during an INPL session. For further details, see the source of `INPLSX01` in the Natural system library SYSLIB.
