Analyze Database File Keys (ANZDBFKEY)

The Analyze Database File Keys (ANZDBFKEY) command produces, from the data generated by the Analyze Database File (ANZDBF) command, two reports showing the key structure of the database files.

One report is written to the printer file QPPTANZK. The other report is written to the printer file QPPTANKM. QPPTANZK contains a listing of the access paths and (logical files only) selection criteria for each key field or selection rule. QPPTANKM contains a matrix of the key fields for all logical files based on the physical file.

Parameters

Keyword	Description	Choices	Notes
FILE	Physical file	Name, *NUMLF	Optional
NUMLF	Min number of logical files	1.0-99999.0, 5	Optional
JOB	Job name	Name, ANZDBFKEY	Optional
JOBD	Job description	Single values: NONE Other values: Qualified object name*	Optional
	Qualifier 1: Job description	Name, QPFRJOBD
	Qualifier 2: Library	Name, LIBL, CURLIB

Physical file (FILE)

Specifies which physical files to select from the list processed by the Analyze Database File (ANZDBF) command. The report includes all logical files associated with each selected physical file.

*NUMLF: Specifies all physical files that have at least a minimum number of associated logical files. The specific minimum is defined by the Min number of logical files prompt (NUMLF parameter).
file-name: Specify the name of a particular physical file.

Min number of logical files (NUMLF)

Specifies the minimum number of logical files associated with a physical file before that physical file is selected. This parameter is valid only when *NUMLF is specified on the Physical file prompt (FILE parameter).

5: At least 5 logical files must be associated with a physical file.
file-count: Specify the minimum number of logical files required.

Job name (JOB)

Specifies the job name to be used if submitting the job for batch processing.

Any value for this parameter is ignored if *NONE is specified for the Job description prompt (JOBD parameter).

Note: If *NONE is specified for the Job description prompt (JOBD parameter), job processing is performed interactively.

The possible job name values are:

ANZDBFKEY: The command name is used for the job name.
job-name: Specify the name to be used for any and all batch jobs.

Batch job description (JOBD)

Specifies the job description used to submit the job for batch processing.

The possible job description values are:

QPFRJOBD: The IBM-supplied job description, QPFRJOBD, is used.
job-description-name: Specify the name of an alternate job description.
*NONE: A batch job is not submitted; processing continues interactively while the user waits. The user's workstation is not available for other use during this time, which could be significant for long jobs.

The possible library values are:

*LIBL: All libraries in the job's library list are searched until the first match is found.
*CURLIB: The current library for the job is used to locate the job description. If no current library entry exists in the library list, QGPL is used.
library-name: Specify the library in which the job description is located.

Examples

ANZDBFKEY   FILE(*NUMLF)  NUMLF(2)

This command produces reports on the keys for all files that refer to physical files with at least two associated logical files.
