Defining exception characteristics

GDFN

Defines or lists exception groups for exception analysis.

This section lists the commands that allow you to customize your exceptions and save the new definitions in a user profile.

With this command, exceptions can be organized by groups such as hardware, software, system services, critical applications, tape and disk drives, and online applications. Then, when you invoke exception analysis by group with the XGRP command, critical and related exceptions appear together on the display.

Type:

Immediate

Format:


GDFN      
     [GROUP=cc]
     [LIST=cccc,aaaa NAME=’ccc∥ccc’]
     [POSITION=nn]
     [DELETE=EXCEPTION LIST=cccc,aaaa]
     [DELETE=GROUP]

(Blank): Lists user-defined and IBM-defined exception groups along with the exceptions included in each group.
GROUP=cc: Specifies the 2-character exception group ID. A group ID can be any two unique alphanumeric characters. To list the entries for an existing group, enter this keyword and the group ID.
LIST=cccc,aaaa,∥: Lists and adds exceptions to the exception group specified with the GROUP= keyword. An exception may be associated with only one group at a time.
NAME=’ccc∥ccc’: Specifies a 25-character user-defined description of the exception group. Enclose in single quotes if there are blanks, special characters, or single quotes in the name.
POSITION=nn: Specifies the order in which GDFN displays defined groups. The variable nn is a position number for the specified group relative to the other groups.
DELETE=EXCEPTION: Deletes exceptions specified with LIST= from the group specified by the GROUP= keyword. Note that the syntax does not allow you to use the DELETE keyword followed by a list of exceptions. You must enter the LIST keyword.
DELETE=GROUP: Deletes the entire exception group specified by the GROUP= keyword.

For example, to define the group SP and its related exceptions, enter:


GDFN GROUP=SP POSITION=1 NAME=’SYSTEMS PROGRAMMER’
GDFN GROUP=SP LIST=ABND,ELAP,MAXU,PSCU,SLOG,TSOR,WAIT,XCON
GDFN GROUP=SP LIST=XCSA,XDDR,XECS,XGRS,VISC,XRMF

To delete specific exceptions from group TX, enter:


GDFN GROUP=TX DELETE=EXCEPTION LIST=WSHI,WSLO

To delete the group TX and all its related exceptions, enter:


GDFN GROUP=TX DELETE=GROUP

Important: In the examples of the GDFN DELETE keyword, note that you must specify what type of delete function you want GDFN to perform: delete only individual exceptions that you list (DELETE=EXCEPTION and LIST=exception,||), or the entire group (DELETE=GROUP).
