OMI - Sessions

1995 Version of ANSI (Equivalent to Current ISO Version) of Standard

Right Hand Pointer

4.3.1 Sessions

OMI uses one circuit to establish a session between exactly two OMI nodes. However, implementers may supply servers that support many sessions, to give several client nodes access to the server node's database. Implementers may also permit more than one session on a client node, so that different client processes may refer to data on several server nodes. However, a particular client shall connect to a particular server through only one session at a time, because duplicate paths between a client and a server could cause transactions to be processed out of sequence.

Initiation and termination of sessions shall be invisible to application programs. The implementation shall establish and terminate sessions as necessary to perform OMI operations.

A session is not symmetric. Requests from one client node are satisfied at the other server node. Another session is needed to handle requests in the opposite direction.
