CEMT SET CONNECTION
RELeased (
appc only
)
specifies whether CICS is to release a session with the
logical unit represented by the CONNECTION name. To
get more detailed information about the availability status
of the connection elements, use the CEMT INQUIRE
MODENAME command.
RESync (
mro to CICS Transaction Server for OS/390 and
later systems and appc only
) (APPC parallel-session,
CICS-to-CICS MRO, and LU61 only)
Any UOWs shunted due to the failure of this connection
are to be retried (that is, exchange lognames
resynchronization for this connection is to be attempted).
This process should normally be started automatically
when a connection is acquired or when a UOW is
unshunted. The normal resynchronization process is to
be partially overridden: decisions are taken for any units
of work that are in-doubt due to a failure of the
connection; but the decisions are recorded and any data
inconsistencies are reported when the connection is next
acquired.
Notes:
1. The COMMIT, BACKOUT, FORCEUOW and
RESYNC operations are synchronous with setting
the state of the UOW; that is, an INQUIRE UOW
following SET CONNECTION BACKOUT, COMMIT,
FORCEUOW, or RESYNC returns the new UOW
states.
2. Specifying one of these options unshunts all units of
work that have failed due to a failure of the
connection. Before issuing SET CONNECTION
FORCEUOW, you may want to use the SET UOW
command to specify commit or backout for each
in-doubt unit of work explicitly, rather than letting it
default, Local procedures determine the importance
of the data and the method of using the INQUIRE
UOW, INQUIRE UOWENQ, and INQUIRE
UOWLINK commands to establish the correct
actions.
3. You can specify only one of the BACKOUT,
COMMIT, FORCEUOW, RESYNC, NOTPENDING,
and NORECOVDATA options. SET CONNECTION
NORECOVDATA should be used only in exceptional
circumstances.
4. To force all in-doubt units of work caused by a
failure of the connection in the same direction, use
SET CONNECTION COMMIT or SET
CONNECTION BACKOUT.
5. The BACKOUT, COMMIT, FORCEUOW, or
RESYNC options of SET CONNECTION and SET
UOW do not clear resync information. If you want to
do this, you must use SET CONNECTION
NOTPENDING or SET CONNECTION
NORECOVDATA.
6. You can issue BACKOUT, COMMIT, FORCEUOW,
or RESYNC commands
before
issuing SET
CONNECTION NOTPENDING or SET
CONNECTION NORECOVDATA.
