Introduction to the NOF API
NOF Verbs to Manage Specific SNAplus2 Functions
Chapter 1 81
However, you may want to set up entries for particular nodes or LUs so
that the local node can communicate with these resources without
having to search for them. Because setting up entries for particular
nodes or LUs overrides the normal APPN resource location process, you
can have problems at this node or at other nodes in the network if the
definitions are not correct. Do not define explicit entries for resources at
other nodes unless you are sure that the definitions are correct.
To define an individual node, LU, or wildcard entry for a range of LUs,
use the following verb:
• DEFINE_DIRECTORY_ENTRY
To delete an individual node, LU, or wildcard entry from the directory,
use the following verb:
• DELETE_DIRECTORY_ENTRY
Delete only directory entries that were explicitly defined using the verbs
described previously (these entries return an entry type of HOME on the
QUERY_DIRECTORY_ENTRY verb). Do not use this verb to delete
cached entries (entries that have been set up dynamically as a result of
network searches).
Querying the Network Topology
To obtain information about the TGs to adjacent network nodes, use the
following verb:
• QUERY_LOCAL_TOPOLOGY
Checking the Communications Path to a Remote LU
To check that a particular target LU can be accessed (that the node
owning the LU is active and that there is a communications path to the
LU), use the following verb:
• APING
Managing Servers on the SNAplus2 LAN
To obtain a list of servers (nodes) on the SNAplus2 LAN, use the
following verb:
• QUERY_NODE_ALL
