Specifies the name of an XRC session that is to have its coupling
status changed. It can refer to an uncoupled session or a coupled
XRC session. This name can be any name acceptable to TSO that matches
the name of a session that was previously specified on the XSTART
command. The maximum length of the name is eight characters. Do not
include embedded blanks. TSO ignores the leading blanks and the trailing
blanks.
(ADD | DELETE | PURGE)
(ADD) indicates that the specified XRC
session session_id is to be added or coupled to the group
of sessions that is associated with the master session. (DELETE) indicates
that the specified active XRC session session_id is to be
removed or uncoupled from the group of sessions associated with the
master session. (PURGE) removes information
about the XRC session from the master data set when the XRC session
is inactive.
MSESSION(msession_id)
Specifies the name of the master session. The master session
is a logical entity that is used to coordinate session commands and
data consistency across multiple XRC sessions. A master session exists
as long as there is an XRC session coupled to the master session.
The maximum length of the name is eight characters. Do not include
embedded blanks. TSO ignores the leading blanks and the trailing blanks.
This parameter is not used on the XCOUPLE DELETE command.
