Use this command to display information about one or more logical units
(LUs).
Requirements and Restrictions
- You can enter this command only in 1052 state or higher.
- Information about parallel sessions is not included in displays that
contain more than one LU.
Format
- ID-netid.luname
- displays information about one or more LU, where netid is the 1-
to 8-character network identifier and luname is the 1- to 8-character
name of the LU. The network ID and name of a resource must both
begin with a letter (A-Z), @, #, or $.
The remaining characters can be letters (A-Z), numbers (0-9),
@, #, or $.
Notes:
- Use the asterisk (*) as a global file-name character to specify a group of
network identifiers or LU names that begin or end with a common string of
characters. For example, to display information about all the LUs that
have a name beginning with PP, enter:
ZNDLU ID-PP*
To display information about all the LUs in the ALPHA network, enter:
ZNDLU ID-ALPHA.*
- To specify an SNA network ID or resource name that contains dollar
signs ($), you must type two consecutive dollar signs
($$) for each dollar sign in the network ID or resource
name. For example, if the SNA resource name is $SNANAME, you must type
$$SNANAME.
- Mode-modename
- displays information about the sessions started for TPF Advanced
Program-to-Program Communications (TPF/APPC) LUs that have the specified mode,
where modename is the 1- to 8-character name of the mode.
Mode names must begin with a letter (A-Z), @, #, or
$. The remaining characters can be letters (A-Z),
numbers (0-9), @, #, or $.
- Note:
- To specify a mode name that contains dollar signs ($), you must
type two consecutive dollar signs ($$) for each dollar sign in
the name. For example, if the mode name is $MODNAME, you must type
$$MODNAME.
- ALs-alsname
- displays information about the logical units (LUs) that started a session
through a specific adjacent link station (ALS), network control program (NCP),
or channel-to-channel (CTC) resource, where alsname is the 1- to
8-character name of the ALS, NCP, or CTC resource. The network ID
and name of a resource must both begin with a letter (A-Z), @,
#, or $. The remaining characters can be letters
(A-Z), numbers (0-9), @, #, or
$.
- Note:
- To specify an SNA network ID or resource name that contains dollar signs
($), you must type two consecutive dollar signs ($$) for
each dollar sign in the network ID or resource name. For example, if
the SNA resource name is $SNANAME, you must type
$$SNANAME.
- APplication
- displays information about the LUs that are in session with a specific TPF
application or about the LUs that are not currently in session with a TPF
application, where:
- applname
- is the 1- to 8-character alphanumeric name of an application.
- NS
- displays information about the LUs that are not currently in session with
a TPF application.
- Procedure
- displays information about the LUs for which a session is currently being
started or ended, where:
- Bind
- displays information about the LUs for which a session is currently being
started.
- Unbind
- displays information about the LUs for which a session is currently being
ended.
- Rtp-index
- displays information about the logical units (LUs) that are in session
across a specific rapid transport protocol (RTP) connection, where
index is the 1- to 6-digit hexadecimal rapid transport protocol
control block (RTPCB) index.
- Type
- display information about the LUs of a particular type, where
- 0, 1, 2, 3, or 6.2
- displays information about the LUs of type 0, 1, 2, 3, or 6.2,
respectively.
- Any
- displays information about the LUs that are defined in the offline SNA
table generation program (OSTG) as LUTYPE=ANY and are not currently in
session.
- Note:
- If an LU is defined as LUTYPE=ANY and is currently in session, that LU is
considered to be of type 0, 1, 2, 3, or 6.2, depending on how the
session was started.
- PLu
- displays information about the primary logical units (PLUs) that are not
of type 6.2.
- CP
- displays information about the APPN control point (CP) LUs.
Additional Information
- Online help information is available for this command. To display
the help information, enter one of the following:
ZNDLU HELP
ZNDLU ?
- Enter ZNDLU (without any parameters) to display information
about every LU.
- When you enter this command, the TPF system searches the resource vector
table (RVT), entry by entry, for the LUs that match the information you
specified. Only the first 255 matching LUs found in the RVT are in
alphabetic order by LU name in the information that is displayed. The
remaining matching LUs are displayed in the order that they were found in the
RVT.
- You can specify the parameters for the ZNDLU command in any order.
- If you specify an LU name and the LU name does not contain any
asterisks(*), all of the other parameters that you specify in the
ZNDLU command, except the MODE parameter, are ignored.
