LDSN Command

The LDSN command lists data set information from the database including data set attributes, device and volume information, and information about which jobs use the data set or are trigger scheduled as a result of its creation.

This command has the following format:

LDSN,{DSN=dsname|DSNBR={DSnnnnnnnn|DS0nnnnnn*|DS*}}
     [,LIST={DSN|option}]
     [,USERS={0,32767|(minimum,maximum)}]

DSN

Defines the fully qualified name of the data set. For partial qualification, the name can end at a period or can be delimited with an asterisk (*).

Limits: 1 to 44 alphanumeric characters

Required: Yes (unless DSNBR is used)

DSNBR

Defines a single or generic CA WA CA 7 Edition data set number identifying the members whose records are to be listed. Must be entered with the DS prefix. With this option, the major sequence of the output listed is by data set number.

Required: Yes (unless DSN is used)

DSnnnnnnnn: Defines the value for a single CA WA CA 7 Edition assigned data set number in up to eight digits with a prefix of DS. Leading zeros can be omitted.
DS0nnnnnn*: Defines a generic data set number in up to seven digits preceded with DS and terminated with an asterisk. The leading zero must not be omitted. For example, to list all DSNBRs in the range 7000-7999, use DSNBR=DS00007*.
DS*: Specifies all data set records.

LIST

(Optional) Specifies list options for data set information.

DSN: Specifies data set information only. DSN is the default.
ALL: Specifies data set information, "using-jobs" and documentation entries.
EXTL: Specifies data sets that are classified external to CA WA CA 7 Edition.
INTL: Specifies data sets that are classified internal to CA WA CA 7 Edition.
NORM: Specifies data sets shown as NORM on the DB.6 panel. Includes internal and external data sets.
NOUSER: Specifies data sets that have no "using-jobs."
PERM: Specifies data sets shown as PERM on the DB.6 panel.
TRIG: Specifies all the jobs that the data set triggers.
USERS: Specifies all users of a data set. These are jobs that reference the data set in their JCL. Jobs with large JCL may not show in the list (for example, over 100 steps and 500 DDs).

Note: LIST=TRIG and LIST=ALL cannot be used for generic requests by DSN or DSNBR.

USERS

(Optional) Specifies selecting data sets meeting minimum and maximum number of using jobs.

Limits: 5 numeric characters from 00000 to 32767

minimum: Specifies to select data sets with the specified minimum of using jobs.
(minimum,maximum): Specifies to select data sets in the specified range of using jobs.
