Introduction to the NOF API
NOF Verbs to Manage Specific SNAplus2 Functions
1.5.6 LUA Communications
If applications running on SNAplus2 will be using LUA to communicate with host programs, you need to define
the communications link to the host. For more information, see Section 1.5.2,
Getting Started. The definition of
the LS to the host must include the name of a local PU to own the LUs, and must have the
solicit_sscp_sessions
parameter set to
AP_YES.
You then need to define LUs that can be used for LUA. To define the LUs, use the following verbs:
• DEFINE_LU_0_TO_3 to define an individual LU or DEFINE_LU_0_TO_3_RANGE to define multiple LUs
with a single verb
To delete LUs when they are no longer required, use the following verbs:
• DELETE_LU_0_TO_3 to delete an individual LU or DELETE_LU_0_TO_3_RANGE to delete multiple LUs
with a single verb
To obtain information about the configuration or current status of LUs, use the following verb:
• QUERY_LU_0_TO_3
To obtain information about the PU that owns an LU, use the following verb:
• QUERY_PU
If you want to provide LU pools (groups of LUs that can be assigned to applications as required, rather than having
LUs explicitly defined for each application), use the following verbs to define a pool, to obtain information about
the definition, or to delete a pool or remove LUs from it when no longer required:
• DEFINE_LU_POOL, QUERY_LU_POOL, DELETE_LU_POOL
If applications running on SNAplus2 will be using LUA to communicate with applications on downstream computers,
you need to define the LUs on the downstream computer and map these to the LUs on the SNAplus2 node. To
define the downstream LUs, use the following verbs:
• DEFINE_DOWNSTREAM_LU, DEFINE_DOWNSTREAM_LU_RANGE, DEFINE_DSPU_TEMPLATE
To obtain information about the configuration or current status of downstream LUs or about the downstream PU
that serves them, use the following verbs:
• QUERY_DOWNSTREAM_LU, QUERY_DOWNSTREAM_PU, QUERY_DSPU_TEMPLATE
To delete downstream LUs when they are no longer required, use the following verbs:
• DELETE_DOWNSTREAM_LU, DELETE_DOWNSTREAM_LU_RANGE, DELETE_DSPU_TEMPLATE
1.5.7 APPC Communications
If applications running on SNAplus2 will be using APPC to communicate with applications running on host or peer
computers, you need to define LUs that can be used for APPC.
APPC configuration in an APPN network is much simpler than in a pre-APPN SNA network. Many of the required
components, and the interactions between them, can be defined or determined dynamically when sessions are started
and do not need to be specified explicitly in the initial configuration.
Each node includes a default APPC local LU (the “control point LU”). An APPC application can use this LU,
or you can define additional LUs so that different applications can use different LUs. To define the LUs, use the
following verb:
• DEFINE_LOCAL_LU
To obtain information about the configuration or current status of LUs, including the control point LU, use the
following verb:
• QUERY_LOCAL_LU
