Operational Notes

In order to decide where to specify servers and profiles, the reader must

understand how the OSI manager process establishes connections. The following

discussion explains this process. After reading this discussion, read the

considerations for the ENTRY object to see where to specify servers and profiles.

When the OSI manager process receives a request from an application to establish

a connection with another application (attach and connect requests), several steps

happen before the connection takes place. The following discussion explains this

process.

Note The following discussion explains how the OSI manager process selects information from the MIB. In the

tables that accompany this discussion, the OSI manager process uses a hierarchical approach in

selecting one item from each of the tables below. The OSI manager process begins at the top of each list

and moves downward, selecting the first existing item.

Also, in the tables, the words local and remote refer to the two endpoints of a connection and there are

two cases to consider as to how these terms are used.

In the context of a connect request, the application that makes the request is the calling or local address

and the called application is the remote address. In this case, profiles associated with the called (remote)

address take precedence over profiles associated with the calling (local) address. Server specifications

are unnecessary for remote entries and are ignored.

In the context of an attach request, the application that issues an attach request is the called address and

is considered to be the local address—the remote entries in the table are ignored.

1. The OSI manager verifies the required entries. The OSI manager locates the

servers and profiles from the #APPL or other OSI address components

supplied in the attach or connect request call. Servers and profiles are

associated with the following MIB entries:

#APPL entry

#NSAP entry

#SNPA entry

#TSEL entry
