VLFDATA USER subcommand output

This report provides status information relating to the identified programs using VLF at the time the dump was requested. Specifically, the information provided relates to the address space associated with the active task that was using a VLF function. For SCOPE=SYSTEM, the address space is that of the using program that issued the IDENTIFY request and owns the user token.

If VLFDATA USER(uclass) is specified, the report shows the information only for identified users related to a user class.

This information is available only if VLF recovery processing took the dump.

The following information appears in the report:

CLASS identified to: This is the name of the VLF class associated with the using program. It is the class name that was specified in the COFVLFxx parmlib member.

Note: An A-I prefix indicates an IBM-supplied class.

SCOPE of IDENTIFY: The scope of an identify is one of the following values:

HOME - Indicates that only services with the same HASID as the task that issued the COFIDENT macro are allowed to invoke the retrieve function using the UTOKEN returned by the identify.
SYSTEM - Indicates that any services in any address space are allowed to invoke the retrieve function using the UTOKEN returned by the identify.

DDNAME:

Major names in search orderP

These are the major names that are found in the identified user's search order.

If the major name can be translated to characters, it appears in the report as C‘major name’.
If the major name cannot be translated to characters, it is converted to hexadecimal and appears in the report as X‘converted major name’.

The column labeled VLF on the far right contains either:

Y - Indicates that the printed major name is in the user's search order and is specified in a COFVLFxx parmlib member with either the EDSN or EMAJ keyword.
N - Indicates that the printed major name is in the user's search order but is not specified in the COFVLFxx parmlib member.
