Note If concurrent sessions are allowed (see GET-PROFILE-ELEM, Element Identifier 4, for details), the
warning -4005 W-CONCURRENT-SESSIONS might be returned. The application may do an
END-TRANSACTION and continue using this session. If concurrent sessions are not allowed, error
4005 E-CONCURRENT-SESSION might be returned. In this case, the application must abort the
transaction and try later to start a session.

RETN-CODE-DETAIL
is an error number returned by a subsystem other than the TRANSFER delivery
system or is a further qualification of an error detected by the TRANSFER delivery
system.
SERVER-VERSION
is the software version designation of TISERV, returned by the TRANSFER
delivery system. For example, the first version of the TRANSFER delivery system
had a version designation of A01.
TIME-ZONE-DIFF
is the difference between the current timestamps of the server and the requester.
This value is expressed in minutes and rounded to the nearest minute.
Whenever a requester establishes a TRANSFER session, the difference in current
times between server and requester is retained as one of the session attributes.
The TRANSFER delivery system uses this time zone difference to translate all
timestamps into the local database frame of reference prior to storage, and to
translate them back to the local time of the requester prior to replying. Thus,
requesters always communicate with the TRANSFER delivery system in their own
local timeframe, and all timestamps are stored relative to the database local time.
