3.28.2 Supplied Parameters
The application supplies the following parameters:
opcode
AP_DEFINE_LOCAL_LU
lu_name
Name of the local LU. This is an 8-byte type-A EBCDIC string (starting with a letter), padded on the right
with EBCDIC spaces.
To modify the attach routing data or description of the default LU associated with the local node’s Control
Point, set this parameter to 8 binary zeros.
def_data.description
A null-terminated text string (0–31 characters followed by a null character) describing the local LU. This string
is for information only; it is stored in the node’s configuration file and returned on the QUERY_LOCAL_LU
verb, but SNAplus2 does not make any other use of it.
def_data.security_list_name
Name of the security access list used by this local LU (defined using the DE-
FINE_SECURITY_ACCESS_LIST verb). This parameter restricts the LU so that only the users
named in the specified list can use it. To specify that the LU is available for use by any user, set this
parameter to 14 binary zeros.
def_data.lu_alias
Alias of the local LU. This is an 8-byte ASCII string, using any locally displayable characters, padded on the
right to 8 bytes if necessary.
def_data.nau_address
Network accessible unit address of the LU. Specify zero if the LU is an independent LU, or an address in
the range 1–255 if the LU is a dependent LU.
def_data.syncpt_support
Specifies whether the LU supports Syncpoint functions. Set this to AP_YES only if you have a Sync Point
Manager (SPM) and Conversation Protected Resource Manager (C-PRM) in addition to the standard SNAplus2
product. Possible values are:
AP_YES
Syncpoint is supported.
AP_NO
Syncpoint is not supported.
def_data.lu_session_limit
The maximum total number of sessions (across all modes) supported by the LU.
For a dependent LU, this must be set to 1. For an independent LU, specify zero for no limit, or a value in
the range 1–65,535. If you specify an explicit limit, note the following:
• If the LU will be communicating with parallel-session remote LUs, the session limit must include sufficient
sessions for CNOS negotiation; a safe minimum is 3, or an additional 2 sessions for each partner LU.
