The Generate CD-ROM Premastering Information (OPM, QLPCDINF; ILE, QlpGenCdPremasteringInfo) API allows you to do the following:

Generate the distribution set map file
A byte-stream file in the root directory is created and contains information about which tape files reside on each CD-ROM volume (only for files needed by the IBM^® i installation process, such as those saved with SAVSYS or SAVLICPGM). The name of this file is \qlptbdnnnnnnn, where tbdnnnnnnn is the name of the distribution set map identifier that is provided as an input parameter to this API. This file needs to be saved with the name QDSETMAP, using the CPYTOTAP command, to the same set of tapes prior to being sent off for mastering to CD-ROM. This file is written to each CD-ROM volume and is used by programs to ease in intelligent prompting during system installation.
Retrieve information about the files that were saved when the job was enabled for CD-ROM premastering using the Handle CD-ROM Premastering State (QLPCDRST, QlpHandleCdState) API. (Note: Premastering is the set of activities done in preparation for creating a master image as a template for manufacturing a number of copies of a CD-ROM.)
This information includes the tape file name, its corresponding CD-ROM file name (only for files needed by the IBM i installation process, such as those saved with SAVSYS or SAVLICPGM), the CD-ROM volume it will be placed on, and the volume serial position in this set of CD-ROMs. (Note: These files need to reside on the same volume: /QCDIMLP, /QCDIML, /QLANGID/SVvRrMm, /QLANGID/S_Lxxxx, /QLANGID/S_LVLlv, /QFILESCR, /QIAM400, /QFILELDS, /QFILEMCD and /QFILEBT, and these files need to reside on the same volume: /QLANGID/QVvRrMm, /QLANGID/Q_Lxxxx, /QLANGID/Q_LVLlv, /QFILEIPL and /QFILEIN)

Required Parameter Group

Qualified user space name

INPUT; CHAR(20)

The user space that receives the generated list and the library in which it is located. The first 10 characters contain the user space name, and the second 10 characters contain the library name.

The following special values are allowed for the library name:

*CURLIB

The current library is used to locate the user space. If there is no current library, QGPL (general purpose library) is used.

*LIBL

The library list is used to locate the user space.

Format name

INPUT; CHAR(8)

The content and format of the information returned.

The possible format name follows:

PCDL0100

Premastering information

For more information, see PCDL0100 List Data Section.

Distribution set map identifier

INPUT; CHAR(10)

The distribution set map identifier that uniquely establishes this set of CD-ROMs being premastered.

This name can only include the following characters:

Uppercase characters (A-Z)
Numeric characters (0-9)
Underscore character (_)

This identifier should be the same as that specified on the Handle CD-ROM Premastering State API.

CD-ROM size

INPUT; BINARY(4)

The size of the CD-ROM in megabytes that is used during mastering. This information is needed to accurately calculate where the tape files reside on CD-ROM.

CD-ROM volume identifier prefix

INPUT; CHAR(30)

The prefix of the volume identifier for the CD-ROM volumes. Each CD-ROM will be assigned a unique volume identifier starting with these 30 characters. A 2-digit numeric suffix is added to this prefix and then incremented for each CD-ROM volume in the set. For example, the volume identifiers for a 3-volume CD-ROM set when a prefix of MYCDS is used would be MYCDS01, MYCDS02, and MYCDS03.

Error code

I/O; CHAR(*)

The structure in which to return error information. For the format of the structure, see Error code parameter.

Format of the Generated List

The file member list consists of:

A user area
A generic header
An input parameter section
A header section
A list data section:
- PCDL0100 format

For details about the user area and generic header, see User spaces. For details about the remaining items, see the following sections. For detailed descriptions of the fields in the list returned, see Field Descriptions.

When you retrieve list entry information from a user space, you must use the entry size returned in the generic header. The size of each entry may be padded at the end. If you do not use the entry size, the result may not be valid. For examples of how to process lists, see Examples: APIs and exit programs.
