The naming convention for the workspace data sets for remote connections that use the APPC protocol is:

prefix.local_luname.remote_luname_or_wdsqual.ds_identity

where:

prefix

Is a value you specify with the PREFIX keyword on the TARGET command

local_luname

Is the LU name of the local node

remote_luname_or_wdsqual

Is the LU name of the remote node if a WDSQUAL value is not specified on the TARGET command. If the LU name for a node is a qualified name in the form netid.luname, RACF® uses only the second part of the qualified LU name in the names of the workspace data sets. If a WDSQUAL value is specified on the TARGET command, RACF uses that value instead of the LU name of the remote node.

ds_identity

Is either INMSG or OUTMSG
